Appearance

The low profile dome provides an economical solution when circular rooflights are required. We supply as either dome only to fit existing upstands or can be supplied with an insulated GRP kerb.

Quality

Mardome Roofligths are designed and manufactured under an ISO9001 approved quality system
BBA Approval - Full BBA approval under 06/4385

Composition

Outer dome is manufactured from 3mm impact resistant Marlon FSX Longlife polycarbonate sheet which has a UV Protective coating on both sides. This coating stabilises the product to avoid discolouration and weakening due to exposure to sunlight. Where double and triple glazed domes are being used, the inner domes are manufactured from 2mm thick impact resistant Marlon FSX longlife polycarbonate sheet. Polycarbonate is has an impact strength 200 times greater than glass which makes breakage very difficult.

The kerb is manufactured from insulated Glass Reinforced Plastic (GRP) with a gloss gel coat layer to the inside. This gives a smooth, maintenance free surface with excellent reflective properties.

Fire Rating

Building Regulations Approved Document B (2006 edition amended 2007) sets out the rules for fire safety of buildings, which can be met by achieving specific fire ratings to either British (BS476) or European (BS EN 13501) test standards.
Brett Martin Daylight Systems Mardome Circular Rooflights achieve Class B s1, d0 to BS EN 13501: Part 1. Building Regulations state they can be regarded as Broof (t4).
