Zenon Roof Lights

This is not always obvious, as cooling due to rainfall can cause condensation. 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

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,

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

As a component manufacturer, we are not in the position to advise on risk assessments and method statements for construction for site works. Please remember that rooflight panels installed in ‘walkable’ liner systems should still not be walked on.

No, it is not necessary with GRP rooflights but may be a requirement with other rooflight materials.

Saddle washers are not required with Zenon rooflights.  The recommendation on all GRP trapezoidal profiles is to fix in the trough of the sheet, using a self-drilling, self-tapping fastener with a minimum 29mm diameter washer.  Saddle washers are only required where an oversized hole should

The material and performance of the fastener is not something that we would generally specify or make any specific recommendations on other than following recognised good industry practice. It is generally now accepted that for cladding systems and rooflights incorporated into them to meet their

In accordance with recommended industry practice, and to ensure that the expected non-fragile rating is achieved, sufficient overlap should be allowed for on-site tolerances so that the fasteners can be installed a minimum of 50mm from the sheet end. For site assembled rooflights, we normally

All rooflights should be stored off the ground and under cover to protect from UV and weathering prior to installation.

All Zenon rooflights should be handled, stored off the ground and adequately supported in accordance with the pallet labelling until installed.
