Consistent design

Our gable end glazing, made up of angled units, is perfectly suited to sit above windows, sliding or bifold doors. Wherever possible, we try to match the frames of the gable end glazing to the sight lines of the doors or windows below to provide a clean look to your design.

Increasing natural light

Whether they extend over a single storey or two floors, pitched roof extensions or renovations with glazed gable ends help provide bright internal spaces, pulling in natural light even as the sun lowers in the sky in the evenings

A real design statement

Pitched roofs really add to a home’s architectural appeal. For two storey gable ends using full-height fixed frame windows (stacked on top of each other with the structural join clad in aluminium to match the frames) provides a design statement for any extension, new-build or particularly barn conversion or period-renovation.

Full, part or offset gable ends

Every one of our angled fixed frame windows is designed in house and made to order to your exact requirements by our own team of experienced fabricators, ensuring whatever your design or pitched roof angle we can incorporate our glazing to suit.
