Toughened Glass Systems framed flat rooflight is priced competitively without compromising on quality. Boasting a centre pane U-value of 1.1 W/m2K the rooflight we supply is one of the most thermally efficient double-glazed roof lights available.

Unlike other competitors rooflights which are supplied with bottom pane 6mm toughened glass, this product comes with a 6.4mm minimum inner laminated glass. For larger rooflights the inner pane will be 9.5mm or 11.5mm lami. Laminated panes are produced by bonding a film, or interlayer between two or more plies of glass. Upon fracture, the interlayer holds the broken shards of glass, preventing injury to those immediately below the rooflight. Toughened glass would shatter into thousands of prices risking injury to those below the rooflight. Use of laminate glass on the bottom which we supply makes our rooflight product much safer compared to toughened glass only on the bottom pane which is what most other competitors offer.

Please delivery tab for more information on lead time. The skylights simply fit directly on top of the existing builders upstand/kerb.  The skylight is manufactured to ISO 9001 industry standards in the UK.

Please see delivery tab for lead time information for all sizes.

Measuring & Installation Guide

Please see fitting instructions below and downloadable PDF link at the bottom of this page. Please note the prices listed on this page do not include a upvc upstand, these are to be fitted on a builders upstand. If required upstand can be supplied at an additional cost.

Please note size you purchase from the drop down menu on the website is based on the external upstand dimensions. If you purchase a 1000mm by 1000mm from our website then your external upstand dimension would be 1000mm by 1000mm. We have 20mm tolerance all around built into our sizes so if your external dimensions were 1020mm by 1020mm this would still fit. The width of your upstand should be 75mm wide.

Acceptable tolerance:

– Fixed Flat Glass Rooflight = rooflight size +20/-0mm

Please note self-clean option is only offered with some sizes and only works effectively at pitches of 10 degrees and above.

A minimum of 5 degree pitch is required for sizes where both the length and width are larger than 1650mm.
