How to Calculate Windows and Glasswork Cost for Any Space

Calculating windows and glasswork cost for any space involves a systematic approach, considering various factors like the type of window, the specific application, and the overall design.

Windows are crucial for aesthetics, light, and insulation. Two popular choices dominate the Pakistani market: Aluminum and uPVC. Understanding their cost differences is key to budgeting effectively. Let's look at the price ranges and what influences them.

A glass price is not a window price.

5 mm clear glass costs PKR 280 to 400 per square foot cut to size. A finished window with that glass in it costs PKR 1,900 to 2,900 per square foot of opening in Lahore, because the frame, hardware, seals and fitting cost more than the glass. Both prices, and everything between them, are set out below for Lahore, Islamabad and Rawalpindi.

Glass price per square foot, by thickness

Clear float glass, supplied and cut to size in the Punjab market. The edge drawn beside each thickness is to scale, so you can see what you are paying for.

In Lahore and Islamabad, clear glass cut to size costs PKR 280 to 400 per square foot at 5 mm, PKR 330 to 500 at 6 mm, PKR 460 to 800 at 8 mm and PKR 610 to 1,200 at 10 mm, rates reviewed 25 September 2026. Tempering adds roughly 18 to 36 per cent.

Clear float glass, supplied and cut to size, PKR per square foot of glass. The low end of each range is an online retailer's cut to size listing; the high end is the upper quote in published window vendor price guides. Tempered ranges apply the 18 to 36 per cent tempering premium observed on the same retailer's listings. Q4 2026 rate set, reviewed 25 September 2026.

Why glass prices online disagree

Search for 5 mm glass and you will find figures from about PKR 140 to PKR 400. They are usually not wrong. They are three different prices for the same sheet.

1. Dealer sheet list

PKR 151/ sq ft

5 mm clear in the most recent dealer list we could find, dated November 2025 and republished in July 2026. Uncut, collected from the dealer.

2. Cut to size

280–400/ sq ft

Cut, edged and delivered in the size you ordered. This is what you pay for a replacement pane.

3. Inside a finished window

Window price per square foot, supplied and fitted

Measured per square foot of structural opening, with frame, glass, hardware, gaskets, fly mesh and fitting included. Four tiers, each defined by what is in it rather than by an adjective.

In Lahore, windows supplied and fitted cost PKR 1,300 to 1,900 per square foot of opening at Essential, PKR 1,900 to 2,900 at Standard, PKR 3,000 to 4,500 at Premium with sealed double glazing, and PKR 4,500 to 7,500 or more at Luxury, rates reviewed 25 September 2026.

PKR per square foot of opening, supplied and fitted. Islamabad and Rawalpindi apply the same uplift used for finishing works on the house construction cost page, between 2 and 6 per cent by tier. DHA adds 6 per cent for the society's inspections and drawing compliance. Q4 2026 rate set, reviewed 25 September 2026.

uPVC and aluminium window prices, by opening type

Published window vendor price lists for Lahore in 2026 quote these ranges per square foot. They are wider than our tiers because vendors mix profile grades within one line. Use them to place a quotation, then check it against the tier it claims to be.

Frame and opening	Published range	Nearest tier	What to know
Aluminium, fixed	1,000 to 1,800	Essential to Standard	No sash, rollers or locks to pay for. The cheapest glazed area in a house.
Aluminium, sliding	1,200 to 3,200	Essential to Standard	The most common Pakistani window. Seals less tightly than a casement.
Aluminium, casement	1,800 to 3,500	Standard	Opens on hinges and compresses its seal, so it keeps dust out better.
uPVC, fixed	1,200 to 1,800	Standard	Also sold as plastic, PVC or fibre windows.
uPVC, sliding	1,500 to 2,500	Standard	Check the profile class and the steel core before comparing prices.
uPVC, casement	1,800 to 3,000	Standard to Premium	Good seal, good value. The usual uPVC choice for bedrooms.
uPVC, tilt and turn	2,500 to 4,500	Premium	Mostly a uPVC product in Pakistan. The hardware is most of the premium.
Aluminium, double glazed	2,500 to 4,800	Premium	Better glass in a frame that still conducts heat, unless it has a thermal break.
uPVC, double glazed	2,800 to 5,500	Premium	Insulating frame and sealed unit together. The strongest value for air conditioned rooms.
Thermal break aluminium	3,200 to 7,000	Luxury	A polyamide strip stops heat crossing the frame. Slim sightlines, large spans.

uPVC or aluminium: which suits Lahore and Islamabad?

Choose uPVC when

The room is air conditioned and you want the frame itself to insulate.

Openings are normal bedroom and lounge sizes, up to about 6 feet wide.

Noise matters: a casement uPVC window seals tighter than any slider.

Choose aluminium when

The opening is wide, a sliding door onto a lawn or terrace, or the sightline must be slim.

The budget is tight and the room is not air conditioned: a 1.5 mm powder coated section is honest value.

You need thermal performance at large spans: then pay for a thermal break, not plain aluminium.

Send us a window quotation. We will tell you what it leaves out.

Most window quotations price a rate per square foot and stay silent on the profile class, the steel, the glass build up and how the frame is sealed into the wall. Those are the four things that decide whether the window is still working in year eight. If you would rather have someone read it line by line, send it over.

Glass partition price per square foot

Framed aluminium partitions, frameless glass walls, shower screens and glass doors. Framed partitions are priced supplied and fitted. Frameless work is priced as glass, because the fittings are chosen per job.

A framed aluminium glass partition costs PKR 1,000 to 1,800 per square foot of partition in Lahore and PKR 1,050 to 1,890 in Islamabad or Rawalpindi, supplied and fitted with 5 or 6 mm glass, rates reviewed 25 September 2026.

Frameless glass partitions and glass walls

A frameless partition is tempered glass standing in a floor channel or held by patch fittings, with polished edges doing the work a frame would. The glass is the part that can be priced from a list. Channels, patch fittings, silicone and fitting are specified per job and quoted separately.

Tempered glass supplied cut to size, PKR per square foot of glass. Same ranges as the glass table above. Reviewed 25 September 2026.

Double glazed glass and window prices

Double glazing is two panes of glass sealed around a spacer, made in a factory. It is priced two ways: as a glass unit, and as part of a finished window. Both are below, along with what actually makes a window soundproof.

A sealed double glazed unit of two 5 mm clear panes with a 12 mm cavity costs PKR 1,510 to 2,050 per square foot of glass, supplied, rates reviewed 25 September 2026. In a finished window it is the Premium tier: PKR 3,000 to 4,500 per square foot of opening in Lahore.

Supplied glass, PKR per square foot of glass, and the Lahore window tiers either side of the upgrade. The online listing for sealed units quotes the sealing charge excluding glass, so the unit price here adds two 5 mm panes cut to size.
Item	Single glazed	Double glazed	The upgrade costs
Glass only, per sq ft of glass	280 to 4005 mm clear, cut	1,510 to 2,0505 + 12 + 5 mm sealed unit	1,230 to 1,650

The limits come from the Energy Conservation Building Code of Pakistan, Energy Provisions 2023, Section 4.1.2: 3.5 W per square metre kelvin where glass is 40 per cent or less of the external wall, 2.5 above that. Note the third bar: a sealed unit in plain aluminium improves the glass and leaves the frame conducting heat.

Soundproof windows and Low E glass

What makes a window quieter

Noise gets in through the weakest path, which is usually the seal, not the glass. A casement or tilt and turn window that compresses its gasket will outperform a sliding window with better glass. After that, a laminated pane or two panes of different thickness in the sealed unit stop the glass resonating. Ask for a tested sound reduction figure, quoted as Rw in decibels to EN ISO 717-1. A window sold as soundproof with no figure is sold on an adjective.

What Low E glass does

A Low E coating reflects radiant heat while letting most daylight through. It earns its cost only inside a sealed unit, in a frame that does not conduct heat itself, on elevations that take direct sun. It is processed to order, so it is quoted per project rather than from a list, and we have not found a published Pakistani rate we would stand behind.

What one window costs, by size

The price of a single window, supplied and fitted in Lahore, at each tier. Most fabricators bill a minimum of about 10 square feet per unit, which is why small windows cost more per square foot than large ones.

A 4 x 4 foot window costs PKR 20,800 to 30,400 at Essential and PKR 30,400 to 46,400 at Standard, supplied and fitted in Lahore, rates reviewed 25 September 2026.

One window, supplied and fitted, Lahore, PKR. Minimum billable area 10 sq ft per unit. Islamabad or Rawalpindi add 2 to 6 per cent by tier, DHA a further 6 per cent. As a cross check, published 2026 Lahore vendor lists put a 4 x 4 aluminium window at PKR 20,000 to 38,000, which sits across the Essential and Standard columns here.

Window replacement cost

Replacing a window in a lived-in house costs the new window from the table above, plus four things a new build does not pay for:

Taking out the old frame without cracking the plaster around it.

Making good the reveals, plaster and paint once the new frame is in.

A new sill if the old one breaks or sits at the wrong level for the new frame.

Carting away the old frame and glass.

These depend on the wall and the finish, so they are priced per opening after measuring. If the opening size changes, the lintel may need attention, and that is a structural question before it is a window one.

Replacing only the glass

A cracked pane in a sound frame needs glass cut to size plus refitting. Use the pane calculator above for the glass. Two cautions. Tempered glass cannot be cut after tempering, so the new pane is made to exact size and takes longer. And a fogged double glazed unit cannot be repaired: the whole sealed unit is replaced.

Building a new house? Your window sizes are fixed at grey structure.

Opening widths, lintel levels, sill heights and the depth of every sunshade are set when the walls go up. By the time a window vendor measures, most of the cost is already decided. Avenir sets the window schedule inside the architectural and structural drawings, so the openings are right before anyone quotes them.

Review my plot requirements Lahore, Islamabad and Rawalpindi.

Where the money sits inside a window

A window is the only part of a house that has to be structural, weathertight, insulating, secure and transparent at once. Tap any item to see where it sits. Every cost argument in the market is about one of these eight things.

Horizontal section through a window jamb, exterior on the left. Drawn diagrammatically, not to scale.

What windows cost for a whole house

A 10 per cent glazed opening allowance applied to typical double storey covered areas, at each tier, in Lahore. The highlighted cell is the tier most owners choose at that plot size, the same default the house construction cost calculator opens on.

For a 10 Marla house of 3,000 sq ft in Lahore, windows and glazing cost PKR 5.70 lakh to 8.70 lakh at Standard and PKR 9.00 lakh to 13.5 lakh at Premium, supplied and fitted, about 4.5 to 6.9 per cent of the Standard finishing budget, rates reviewed 25 September 2026.

Window and glazing package, Lahore, PKR, supplied and fitted, at 10 per cent of covered area. Covered areas match the house construction cost and plumbing cost pages. Islamabad or Rawalpindi add 2 to 6 per cent by tier; DHA a further 6 per cent. Basement glazing is extra.
Plot	Essential	Standard	Premium	Luxury
5 Marla1,900 sq ft covered, 190 sq ft of openings	2.47 lakh to 3.61 lakh	3.61 lakh to 5.51 lakh	5.70 lakh to 8.55 lakh	8.55 lakh to 14.2 lakh

Per square foot of covered area, and as a share of finishing

Same at every plot size, because both the window package and the finishing budget scale with covered area. Finishing rates are the Lahore figures on the house construction cost page.
Tier	Windows per sq ft of covered area	Finishing per sq ft	Windows as a share of finishing
Essential	PKR 130 to 190	PKR 3,500	3.7 to 5.4 per cent
Standard	PKR 190 to 290	PKR 4,200	4.5 to 6.9 per cent
Premium	PKR 300 to 450	PKR 6,300	4.8 to 7.1 per cent
Luxury	PKR 450 to 750	PKR 9,450	4.8 to 7.9 per cent

The decision that moves the bill most

8 per cent240 sq ft of openings4.56 lakh to 6.96 lakh

12 per cent360 sq ft of openings6.84 lakh to 10.4 lakh

15 per cent450 sq ft of openings8.55 lakh to 13.1 lakh

Each outer square is the same 3,000 sq ft house. The inner square is its glazed openings, drawn to true area. Standard tier, Lahore.

Going from restrained to generous glazing, 8 to 15 per cent of covered area, adds PKR 3.99 lakh to 6.09 lakh to a Standard 10 Marla house. Moving the same house from Standard to Premium adds PKR 3.30 lakh to 4.80 lakh. Decide how much glass first, then what kind. Most owners do it the other way round, then economise on the specification to pay for the area.

What the building code requires, and what good looks like

Pakistan has no mandatory performance certificate for residential windows, so nothing stops an untested product being sold. That is why specification, not price, is the thing to argue about. Two reference frames help: the Pakistani energy code, which is law above a size threshold, and the European and American product standards better manufacturers test against voluntarily.

Energy Conservation Building Code of Pakistan, Energy Provisions 2023, National Energy Efficiency and Conservation Authority

Section 4.1.2: Where external glass is 40 per cent or less of the external wall, the heat transmission coefficient must not exceed 3.5 W per square metre kelvin and the shading coefficient 0.76. Above 40 per cent: 2.5 and 0.35.
Section 4.1.3: Maximum solar heat gain coefficient against window to wall ratio: 0.60 at 20 per cent, 0.50 at 30, 0.40 at 40. Visible light transmittance never below 35 per cent.
Section 4.1.4: Openable area above 4 per cent of floor area in mechanically cooled buildings; 50 per cent of window area openable in naturally ventilated ones; safety rails on openable windows above ground.
Section 4.1.5: Horizontal shading on south, east and west at a depth of at least 0.234 times window height. Vertical fins on the west. North exempt.
Section 4.1.7.1: Air leakage through windows and doors not above 2.0 litres per second per square metre.

Does the code apply to your house?

Section 1.3 applies the code at a connected load of 100 kW, a contract demand of 125 kVA, a conditioned area of 500 square metres (about 5,382 sq ft), or an unconditioned covered area of 900 square metres (about 9,688 sq ft). A 5 or 10 Marla house is below every threshold. A fully air conditioned 1 or 2 Kanal house may not be, and then glazing becomes a compliance question. The code also publishes two conflicting solar heat gain tables, 4.4 and 4.5; the figures above are from 4.4. Society byelaws on projections, setbacks and privacy are separate and must be checked for your scheme.

The shading rule almost nobody applies

x ≥ 0.234 y

Energy Provisions 2023, Section 4.1.5. South, east and west elevations. North is exempt.

High sun, stopped by a shade built to the minimum
Low western sun, which gets under it
A deeper overhang, which keeps the glass shaded for longer

Overhang drawn at the code minimum, to proportion. For a 5 foot high window the minimum shade is 14 inches; for 7 feet, about 20 inches. Treat it as a floor, not a target: a sunshade is concrete priced with the structure, and on a west elevation in Lahore it does more than any glass upgrade.

International benchmarks worth asking a supplier about

None of these is mandatory in Pakistan. They define questions with factual answers. Powder coating is normally specified at 60 microns minimum and anodising at 15 to 25 microns: industry convention, worth writing into the purchase order.
What you are testing	Standard	What a good answer looks like
uPVC profile quality	EN 12608-1	Class A: at least 2.8 mm on sight surfaces and 2.5 mm elsewhere. Class B: 2.5 and 2.0. Class C: no minimum.
Air tightness	EN 12207 or ASTM E283	A class from 1 to 4, where 4 is tightest.
Water tightness	EN 12208 or ASTM E331	A class from 1A upwards. This is the monsoon test.
Wind load	EN 12210 or ASTM E330	A pressure class and a deflection class. Matters on upper floors and wide sliders.
Whole window heat loss	EN ISO 10077 or NFRC 100	A U value for the complete window, not the glass alone.
Sealed unit durability	EN 1279	Evidence of a factory sealed unit with a secondary seal and desiccant.
Safety glass	EN 12150, EN ISO 12543, EN 12600	A stamp in the corner of each pane. Doors, side panels, low glazing and shower screens need it.
Sound reduction	EN ISO 717-1	A tested Rw figure in decibels, not the word soundproof.

Windows are settled on the drawings, not in the showroom.

Opening sizes and orientation are drawn to the room, the view and the sun path, so the glass you pay for is glass you want.
Sunshade depths are designed to the 0.234 rule or deeper, and priced with the structure rather than bought as tinted glass later.
Specification by room: uPVC casements where air conditioning runs, aluminium sliders where the opening is wide, safety glass in doors, low level glazing and shower screens.

Nine checks before you sign a window quotation

Each one has caught a real cost problem, and none needs technical knowledge. Tick them off as you read a quotation; nothing is saved or sent anywhere.

0 of 9 checked

Fix the measurement basis. Structural opening, outer frame size, shutter area or aluminium by weight. Two honest quotations on different bases can differ by 5 to 10 per cent before the specification changes.
Ask for the minimum billable area. Usually about 10 to 12 sq ft per unit. A 2 x 2 ft ventilator is then billed as a 10 sq ft window.
For uPVC, ask where the steel is. Galvanised steel of 1.2 to 1.5 mm in frame and sash chambers stops sag. It is invisible once glazed.
For aluminium, ask the wall thickness and finish. 1.2 mm and 1.6 mm sections look identical on a drawing. Mill finish is not a finish.
Treat glass thickness as structural. It follows pane size and exposure. 5 mm that is right at 3 x 4 ft is wrong at 6 x 7 ft.
Confirm double glazing is factory sealed. A spacer, desiccant and secondary seal. Two panes assembled on site will fog within a couple of monsoons.
Check the frame on thermal claims. A sealed unit in plain aluminium still conducts heat through the frame. Pay for a thermal break or choose uPVC.
Get the installation detail. Backer rod and sealant, a drip groove at the head, a sloped and sealed sill, packers at fixing points.
Tie payments to milestones. Balance against delivery, installation and a joint snagging inspection, not a calendar date.

What moves the cost

Window and glazing cost drivers, largest first.
Driver	Effect
Glazed area as a share of covered area	The largest driver. 8 to 15 per cent almost doubles the package on the same specification.
Single glazing to a sealed unit	About PKR 1,100 to 1,600 per sq ft of opening in Lahore, Standard to Premium.
Frame system	Local aluminium to thermal break or Class A uPVC is a two to four times move on the frame.
Opening type	Fixed, then sliding, then casement, then tilt and turn and lift and slide. The cost is in hardware and sealing.
Pane size and span	Large spans need thicker glass, heavier sections and stronger hardware at once. Cost rises faster than area.
Many small openings	Minimum billable areas and per-unit hardware make ten small windows dearer than the same area in five.
Colour and finish	Wood grain and anthracite laminated uPVC carry a premium over white.
Exchange rate	Imported profiles, hardware and coated glass follow the dollar and the euro.
Floor level and access	Above first floor, scaffolding or hoisting is usually quoted separately.

How these rates were built

Glass is priced from an online glass retailer's cut to size listings, read on 13 and 25 September 2026, against the ranges in published window vendor price guides. Where two sources disagree, the range spans both and says so.
Window tiers are set to the overlap of several published 2026 Lahore vendor lists for each frame and glass combination, then defined by what is in them so a quotation can be checked against the tier it claims.
Islamabad, Rawalpindi and DHA use the same factors as Avenir's house construction cost page: the finishing uplift by tier, and 6 per cent for DHA.
Double glazed units add the retailer's sealing charge, which excludes glass, to two panes cut to size. Listing the sealing charge alone as a unit price is a common error.
Partitions are derived from fixed aluminium glazing rates. Whole house figures apply a stated glazing allowance to the same covered areas used across Avenir's cost pages.
Regulatory figures are read from the NEECA code document itself, with section numbers so you can check them.

Honest limits

Every market rate here comes from published retail and vendor sources, not from Avenir's own purchase orders. They are planning ranges.
Rates for thick glass vary more than twice over between sources. The ranges are wide because the market is.
Laminated and Low E glass are not priced: we found no published Pakistani rate we would stand behind.
U values in the drawings are indicative, to show position against the code, not test results for a product.

Questions

All figures from register WGC-2026-09-25, Q4 2026 rate set, reviewed 25 September 2026.

What is the price of glass per square foot in Pakistan?

Clear float glass cut to size costs PKR 180 to 320 per square foot at 4 mm, PKR 280 to 400 at 5 mm, PKR 330 to 500 at 6 mm, PKR 460 to 800 at 8 mm, PKR 610 to 1,200 at 10 mm and PKR 730 to 1,800 at 12 mm in the Punjab market, rates reviewed 25 September 2026.

Uncut sheets bought from a dealer cost less, and glass inside a finished window costs far more per square foot, because you are then paying for the frame, hardware and fitting as well.

What is the price of 5 mm window glass in Pakistan?

5 mm clear glass costs PKR 280 to 400 per square foot cut to size, rates reviewed 25 September 2026. An online cut to size listing showed PKR 328 on that date, and the most recent dealer sheet list we found, from November 2025, showed about PKR 151 for an uncut sheet.

5 mm is the usual glass in Essential and Standard windows for panes up to about 15 square feet. Larger or more exposed panes should step up to 6 mm.

How much do 6 mm, 8 mm, 10 mm and 12 mm glass cost?

Cut to size, clear glass costs PKR 330 to 500 per square foot at 6 mm, PKR 460 to 800 at 8 mm, PKR 610 to 1,200 at 10 mm and PKR 730 to 1,800 at 12 mm. Tempered, the same thicknesses cost PKR 390 to 680, 540 to 1,090, 720 to 1,630 and 860 to 2,450. Rates reviewed 25 September 2026.

The ranges for thick glass are wide because published prices for it vary more than twice over between sources.

How much does tempered glass cost in Pakistan?

Tempered, also called toughened, glass costs PKR 540 to 1,090 per square foot at 8 mm and PKR 860 to 2,450 at 12 mm, supplied and cut to size, rates reviewed 25 September 2026. Tempering adds roughly 18 to 36 per cent to the price of the same clear glass.

Tempered glass cannot be cut or drilled afterwards, so it is made to exact size with every hole marked. It is required for doors, side panels, low level glazing and shower screens.

What is the price of double glazed glass and windows in Pakistan?

A factory sealed double glazed unit of two 5 mm clear panes with a 12 mm cavity costs PKR 1,510 to 2,050 per square foot of glass, supplied, rates reviewed 25 September 2026. A finished double glazed window is the Premium tier: PKR 3,000 to 4,500 per square foot of opening in Lahore.

Moving from a Standard single glazed window to a Premium double glazed one adds about PKR 1,100 to 1,600 per square foot of opening.

What is the aluminium glass partition price per square foot in Lahore?

A framed aluminium glass partition built from standard window sections with 5 or 6 mm glass costs PKR 1,000 to 1,800 per square foot in Lahore and PKR 1,050 to 1,890 in Islamabad or Rawalpindi, supplied and fitted, rates reviewed 25 September 2026. DHA adds 6 per cent.

Doors within the partition, frosting, blinds and proprietary slim office partition systems are extra. Frameless partitions are priced as tempered glass plus fittings chosen per job.

How much does a bathroom glass partition cost in Pakistan?

A shower screen with a 3 foot fixed panel and a 2 foot door, 7 feet high, uses about 35 square feet of tempered glass. In 10 mm glass that costs PKR 25,200 to 57,100 for the glass alone, rates reviewed 25 September 2026. Hinges, handle, seals and the wall channel are extra.

A complete enclosure quoted near the bottom of that range is usually thinner glass, a framed system, or has left the hardware out.

What is the window price per square foot in Pakistan?

Supplied and fitted in Lahore, windows cost PKR 1,300 to 1,900 per square foot of opening at Essential, PKR 1,900 to 2,900 at Standard, PKR 3,000 to 4,500 at Premium and PKR 4,500 to 7,500 or more at Luxury, rates reviewed 25 September 2026. Islamabad and Rawalpindi are 2 to 6 per cent higher and DHA adds 6 per cent.

uPVC and aluminium windows both appear in the Standard and Premium tiers. What sets the price is the profile grade, the glass and the hardware, not the material name.

How much does one 4 x 4 window cost?

A 4 x 4 foot window, 16 square feet, costs PKR 20,800 to 30,400 at Essential and PKR 30,400 to 46,400 at Standard, supplied and fitted in Lahore, rates reviewed 25 September 2026.

Windows smaller than about 10 square feet are usually billed as 10, so a 2 x 2 foot ventilator costs about the same as a 3 x 3 foot window.

Is uPVC or aluminium better for a house in Lahore or Islamabad?

For air conditioned bedrooms and lounges, a multi chamber uPVC casement insulates and seals better for the money. For wide openings, sliding doors and slim sightlines, aluminium is structurally better, and thermal break aluminium closes most of the performance gap at a higher price. Most houses end up with both.

uPVC windows are also sold as plastic, PVC or, loosely, fibre windows. Ask which profile system, which EN 12608 class and whether the frame has a steel core.

How much does window replacement cost?

Replacing a window costs the new window at the per size prices on this page, plus removing the old frame, making good the plaster and paint at the reveals, a new sill if needed, and carting away the old frame. Those extras depend on the wall and finish, so they are priced per opening after measuring.

Replacing only a cracked pane costs the glass cut to size plus refitting. A fogged double glazed unit cannot be repaired and is replaced whole.

Are soundproof windows worth it, and what makes a window soundproof?

Noise gets in through the weakest path, which is usually the seal. A casement or tilt and turn window that compresses its gasket will outperform a sliding window with better glass. After that, laminated glass or two panes of different thickness reduce resonance.

Ask for a tested sound reduction figure, quoted as Rw in decibels to EN ISO 717-1. A window called soundproof with no figure is sold on an adjective.

Why do glass price lists online show different prices?

Because they quote different things. A dealer sheet price is for an uncut sheet collected from the dealer. A cut to size price includes cutting, edging and delivery. A window price is per square foot of opening and includes the frame and fitting.

Several lists carrying a 2026 date also repeat a table first published in March 2023, with 5 mm clear at PKR 142. Check the date and the basis before comparing any two figures.

How much should I budget for windows in a 10 Marla house?

For a 10 Marla house of about 3,000 square feet in Lahore, with glazing at 10 per cent of covered area, budget PKR 5.70 lakh to 8.70 lakh at Standard and PKR 9.00 lakh to 13.5 lakh at Premium, supplied and fitted, rates reviewed 25 September 2026. That is about 4.5 to 6.9 per cent of the Standard finishing budget.

How much glass you design in moves the budget more than the tier: 8 per cent glazing and 15 per cent glazing on the same house differ by nearly double.

What does the Pakistani building code require for windows?

The Energy Conservation Building Code of Pakistan, Energy Provisions 2023, limits the heat transmission of glazing to 3.5 W per square metre kelvin where glass is 40 per cent or less of the external wall, and 2.5 above that. It caps solar heat gain by window to wall ratio, requires openable area and safety rails, and requires sunshades at least 0.234 times the window height on south, east and west elevations.

The code applies above set thresholds, including 500 square metres of conditioned area, about 5,382 square feet. Most 5 and 10 Marla houses are below them; a fully air conditioned 1 or 2 Kanal house may not be.
