A Trapezoid Window is a custom-shape window designed for non-standard rooflines, gables, attics, or lofts.

Its trapezoidal geometry (two parallel sides and two angled sides) allows it to fit sloped walls, gable ends, or angled ceilings — ideal for converting attics, lofts, or unusual roof spaces into bright, usable rooms.

The trapezoid shape becomes a striking architectural detail while still providing light and ventilation.

Materials & Customization
You can choose the frame material — PVC (uPVC), aluminum, wood, or a combination — depending on project requirements. The window shape, angles, and size are customizable, so you can adapt the trapezoid to match your roofline or wall geometry. For insulation and comfort, you can combine frame material with double- or triple-glazing. This flexibility allows for custom solutions in loft conversions, gable walls, or any space with non-standard geometry.

Applications
Attic windows / loft conversions
Gable-end windows under pitched roofs
Bathroom, stairwell, or hallway windows with angled ceilings
Architectural accent windows for modern or classic homes
Renovations or custom builds needing special-shape glazing

Pricing & Ordering (Estimate)
Because each Trapezoid Window is custom configured — size, shape, material, glazing, finish — pricing depends on all these factors. Customers must submit the exact geometry and configuration to get a quote. Expect costs higher than standard rectangular windows due to custom fabrication, shaping, and specialized glazing.
