    How do I repair a rooflight that has been damaged?

    Tom-April 27th, 2023-

    Generally, and to maintain the non-fragility status of a rooflight, any damaged rooflights should be replaced. The need to ensure that the non-fragile status is maintained means that repair kits can no longer be used effectively.

    Tom-April 27th, 2023-

    This kind of information should be contained in the building records or building maintenance manual. Our rooflights are printed along their edge with identification marks, relating to the manufacture and specification of the product. This can only be applied to the outer surface of the

    How do I know if my roof is leaking or just condensation?

    Tom-April 27th, 2023-

If a rooflight is leaking, it will generally correlate regularly with certain weather conditions, even if not immediately obvious. Condensation is more likely to occur during colder weather and damper conditions irrespective

  • What happens if a rooflight gets damaged?

    What happens if a rooflight gets damaged?

    Tom-April 27th, 2023-

    To preserve the non-fragility classification and service life guarantee, in most instances rooflights would require replacement. Small areas of damage that appear slightly cloudy or as a ‘bloom’ where the structure of the rooflight sheet has not been compromised, and the surface film is undamaged,

  • How should you clean rooflights?

    How should you clean rooflights?

    Tom-April 27th, 2023-

    Zenon rooflights can be cleaned with a mild detergent or soap solution and a soft bristled brush.  Care must be taken to prevent any damage to the surface film protection. Separate details are available upon request. Pressure washing should not be used on metal cladding
