Frequently Asked Questions

How much does a UPVC window cost per square metre?
Supply-only UPVC window pricing typically sits between £180 and £320 per m² depending on profile system, glass spec, and colour. Doorwin recalculates per project using your own supplier price list — the figure you see is what you quote.
Can I include installation labour in the estimate?
Yes. Set a daily labour rate, a flat fit cost per window, or a percentage uplift. Scaffolding, trims, silicone, and disposal line items are available as optional extras.
Does it handle triple glazing and aluminium spacers?
Triple-glazed 36mm and 44mm units are fully supported. You can choose aluminium, warm-edge (Super Spacer, Swisspacer), or steel spacer bars — each with its own cost and U-value impact.
Is the calculator accurate for trade and retail pricing?
Yes — Doorwin separates cost price from sell price with configurable markup per window type. Trade customers see the net figure; retail quotes include your margin, VAT, and optional warranty.
