These include single skin and Cornforth factory assembled insulated GRP rooflights (FAIRS), GRP and polycarbonate domes and multi-wall polycarbonate glazing systems.

Cornforth rooflights become discoloured over time from exposure to ultra violet radiation.

This discolouration can be mistaken for dirt, but often attempts to clean them has no effect as the discolouring is a result of fibres within the GRP changing colour.

Sometimes a Cornforth roof may have twin skin rooflights, an internal and external layer. Sometimes the problem may only be within the top sheet allowing us to simply replace with new or both may require replacement.

Ageing skylights can become problematic, whether it’s leaking fixings, cracks in the fibreglass or other related problems. However, we are able to effectively prolong their serviceable life with expert repairs using specialised products.
