Frame
The outer structure fixed into the opening. Choose white or a colour finish, with Deceuninck or VEKA Halo profile recorded on the quote.
Windows and style builder
Design the window, understand the price.
Start with an exact matrix style or build your own layout. Add every room to one quotation and see how the job price changes as the basket grows.
Window anatomy
Know what you are choosing.
Sash
The part of the window that can open. A fixed pane has no opening sash. Side and top openers change the factory configuration.
Mullion
A vertical division between sections. A horizontal division is often called a transom. Together they create the layout.
Glass
Clear, privacy or safety glass. The right specification depends on location, pane size and the final survey.
Build your quotation
Your proper window designer.
Choose an existing matrix design for instant pricing, or switch to Build custom and click each pane to cycle between fixed, side-opening and top-opening. If the exact custom layout is not in the matrix, we will price it manually.

One vent is already included per window.

How safety glass is handled
The designer flags critical glazing zones.
For a normal window away from a door, glazing that enters the zone below 800 mm from finished floor level may need safety glazing. Beside a door, the critical area extends to glazing within 300 mm of the door and below 1500 mm.
What the calculator does
- Marks the panes likely to enter a critical zone
- Adds an estimated toughened-glass area allowance
- Records whether the window is beside a door
- Records a possible escape-window requirement
- Leaves the final compliance decision to the survey
Permanent fixtures, stairs, outside drops, pane dimensions and alternative compliant glazing can affect the final specification.
Transparent, not reckless
What the live price can and cannot promise.
The estimator uses the current customer-facing matrix for white uPVC casement windows. It moves your measurement up to the next listed width and height. Colour upgrades, unusual access, structural work, non-standard glass, custom layouts and anything outside the matrix are confirmed after review.
All estimates remain subject to final survey and factory confirmation. Nothing becomes an order until you approve a written quotation and contract.
