Our unique fixed triangular rooflight uses the same structural silicone glazing techniques as our entire range of rooflights, ensuring a very high-quality product, manufactured at our factory in Leicester. It comes fully watertight with a premium flush glazed and refined aesthetic.
All our shaped rooflights feature fully enclosed double glazed units to eliminate any risk of breakage. Please note that traditional ‘stepped edge’ shaped glass rooflights have a significantly higher vunerability to breakage due to exposed edges.
Duplus roof lanterns are double glazed in clear HEATSOAKED toughened safety glass as standard.
Options are available:
Our fixed rooflight is easy to install. An integral perimeter gasket creates an air and water seal without the need for site applied silicone. The product is secured via screw fixing to the builders kerb externally and a matching cover clip is then applied to conceal the fixings.
Yes, we can construct isosceles-shaped triangular rooflights. Just let us know your required dimensions and we can provide you with a quote directly to your inbox.
All our rooflights satisfy the thermal performance criteria defined in the Building Regulations and achieve a high resistance to condensation under normal conditions. We can provide True U-value and Ud-values upon request.

As standard, the extruded aluminium perimeter frame is powder-coated RAL 7016 dark grey matt or RAL 9005 black matt. We can offer other RAL colour options upon request.
Our glazing specifications incorporate clear low ‘E’ glass as standard, achieving a centre pane U-value of 1.1 W/m²K.
