Glass is the fastest growing material of choice for roof glazing products. Xtralite offers a comprehensive range to meet the most exacting project requirements.

Offering an excellent combination of thermal insulation perofmrnace and light transmission, plus the opportunity to opt for solar control properties and/or coloured glazing, glass is the perfect choice. All Xtralite glass rooflights are manufactured using toughened and laminated glass ensuring non-fragility and safety standards are met or exceeded.

Xtralite glass rooflights can be supplied in a number of configurations, as shown below. Each rooflight is made to order, so we are able to offer a bespoke service to manufacture products to your exact size requirements.

Low Profile Glazed Units


Low profile glass rooflights can be supplied to fit your own upstand (kerb) or manufactured to include a kerb and roof fixing attachments. A range of thermal performance options are available, with u-values compliant with, or exceeding, the requirements of Building Regulations, Part L.

Flush Fitted, Glass Walk-On Rooflights 


As the name suggests these rooflights fit flush to the exterior roof surface and are supplied in toughened, laminated glass enabling them to be walked on when traversing the roof. Glass walk-on rooflights are ideal for modern, flat roofed extensions.
