This calculator does two things. It works out the real area and panel sizes of your opening, so you know exactly what you are buying, and it lets you price the window either as a single all-in rate per square foot or as separate lines for profile, glass, mesh, hardware and fitting. Pricing it both ways is often the fastest way to see whether a quote makes sense.

What This Tool Does

It calculates the opening area in square feet and square metres, the outer frame perimeter in running feet, and the approximate width of each sliding panel. Then it prices the window using either your complete per-square-foot rate or your itemised rates, and multiplies up if you are buying several of the same size.

Who It Is For

• Homeowners getting aluminium windows quoted for a new house or a replacement job.
• People comparing two fabricators who want to normalise both quotes to the same scope.
• Builders and contractors pricing windows across a project.
• Aluminium fabricators who want a quick estimate sheet to hand a customer.

How To Use It

1. Measure the window opening in the wall, width and height. Measure at more than one point and use the smaller figure, because openings are rarely true.
2. Choose the window type: two track sliding, three track sliding, fixed glass, openable casement, or a sliding door.
3. Enter how many windows of this exact size you need.
4. Choose how your rate is quoted. If your fabricator gave you one figure per square foot, pick the complete rate option and enter it.
5. If you want to see where the money goes, switch to itemised and enter the profile rate per running foot, the glass rate per square foot, mesh, hardware and fitting separately.
6. Press the button. For the itemised route, ask your fabricator for the actual profile length their system consumes, because the outer frame perimeter alone understates it.

Inputs And Units Explained

• Opening width and height — the masonry opening the window has to fill. Everything else is derived from these.
• Window type — the number of panels follows from this: two track gives two panels, three track gives three.
• Complete rate per square foot — the all-in figure most Pakistani fabricators quote, covering profile, glass, hardware and usually fitting. Ask what it includes.
• Profile length and rate — for itemised pricing. Profile consumption depends on the brand and series, so get the running feet from your fabricator or their catalogue rather than assuming.
• Glass rate per square foot — for the glazing. Thickness changes this significantly.
• Mosquito mesh — priced on roughly one panel of area when you tick it.
• Hardware and fitting — locks, rollers, handles and the labour to install, per window.

How The Calculation Works

Area is width times height, converted to square feet at 10.7639 square feet per square metre. The outer frame perimeter is twice the width plus twice the height, expressed in running feet, which is what profile is sold by. Panel width is the opening width divided by the number of panels, which is a geometric split and ignores the sash overlap that a real system adds.

With a complete rate, the estimate is simply area times rate times quantity. With itemised rates, the tool prices profile by running feet, glass by area, mesh by roughly one panel of area, and adds hardware and fitting per window. If you leave the profile length blank it falls back to the outer frame perimeter and says plainly that real consumption is higher, because sashes, tracks and beading all consume profile that the outer frame does not account for.

Worked Example

A lounge window in a Rawalpindi house measures 5 feet by 4 feet, two track sliding, and the fabricator has quoted a complete rate per square foot.

Input or result	Value
Opening	5 ft × 4 ft
Area	20 sq ft (1.86 m²)
Type	Two track sliding, two panels
Outer frame perimeter	18 running ft
Approximate panel width	about 2 ft 6 in each

Twenty square feet is the number that matters. Multiply it by the rate quoted and you have the window price, and multiplying by the number of identical windows gives the order total. If a second fabricator quotes a lower rate, the question to ask is which profile series and glass thickness that rate assumes.

Features And Benefits

• Honest area and perimeter figures, so a per-square-foot quote can be checked in seconds.
• Two pricing modes, so you can compare an all-in rate against the sum of its parts.
• Panel widths calculated, which is what tells you whether a sliding window will feel right.
• A printable estimate with specification notes to attach to your enquiry.
• No assumed rates anywhere, so nothing goes stale.

Assumptions And Accuracy Limits

• Profile consumption is brand and series specific. Without the real figure from your fabricator, the itemised mode understates profile.
• Panel widths here are geometric. Actual sash overlaps and track deductions come from the system catalogue.
• The tool does not judge whether a profile is heavy enough for the panel size, which is a real limit on large sliding windows.
• Nothing is included that you have not entered, so check whether your quote covers mesh, fitting and silicone.

Common Mistakes To Avoid

• Comparing rates without comparing the profile series. Ask for the series name and the wall thickness in writing from every fabricator.
• Forgetting the glass. A quote with 4 mm glass and one with 5 mm are not the same window, and on large panels the difference matters.
• Measuring the old window instead of the opening. Measure the masonry, and let the fabricator work out their own deductions.
• Assuming fitting is included. It often is, but when it is not it can be a surprise at the end of the job.

Aluminium Window Price In Pakistan: What Changes The Number

Searching for an aluminium window price in Pakistan gives you rates per square foot, but the final figure changes with the section thickness, the glass, the colour finish and the type of window. A fixed window and a sliding window of the same size are not priced alike, and a 1.6 mm section is not priced like a 1.2 mm one.

This calculator keeps those pieces separate. You enter the size, the section, the glass thickness and the rate your supplier has quoted, and it adds up each part. If two quotes for the same window are far apart, the gap usually lies in one of those inputs, and the tool shows you which.
