For non standard sizes, we can offer two solutions, one being our 'adapter kerb' (see data sheet) which is manufactured to suit our standard range and splayed at base to suit existing kerbs. The second option, and preferred method for difficult propositions whilst maintaining cost effectiveness, is our 'Bridge mould' (see data sheet) which will allow greater tolerance of fit without the need for an adapter kerb.

Manufacture:
Thermoformed from 3mm thick polycarbonate sheet, and available as single, twin or triple skin units, our roof lights benefit from high impact resistance and long life, due to the UV protective coating applied to the outer skin during sheet manufacture. A wide range of colour and transparency options are available to suit the majority of applications, the most commonly supplied to our clients being clear, clear patterned or opal. Please contact our technical staff if you require colour samples or information on additional colour options.

Size Explained:
Our standard rooflight @ 900 x 900, would have a clear light size of 750 x 750 (150mm less than overall size).

Cleaning / Maintenance:
Cleaning - Thermoformed roof lights should be washed down with a mild detergent and warm water. Do not use abrasives.

Maintenance - Annually check mechanical components, and lubricate where necessary, actuating components.

Points to check prior to advising us of your requirements:
When placing an enquiry/ order please be sure to note the roof opening size , and where possible the width of the upstand kerb.

Impact Test:
At the request of Nulite Ltd, B.R.E tested various size samples of Domed roof lights with either a PVC or steel upstand kerb, the test assesses the fragility of the specimen roof light when subjected to an impact by a large soft body as in the standard ACR (m) 001:2000 (full details on the test report are available on request).
