Marvault Features and Options

Components

Vaulted rooflight system in two height options - 1/6 for a gentle low curved arched profile and a 1/2 for a dramatic semi-circular effect, capable of spanning up to 5 metres.



 

Light Levels

The provision of natural daylight is a regulatory requirement, with recommendations for a minimum rooflight area of 10%, a 12% area for industrial buildings, and a greater percentage of rooflights for buildings such as sports halls etc.

Compatibility 

Vault rooflights from are compatible with most commonly used building materials. However, solvents and alkaline cleaners should not be used with any vault rooflight. Polycarbonate vault rooflights should not come into contact with any plastisol coated steel.

Kerbs

Appropriate roof apertures and insulated kerbs in either timber, steel, GRP or concrete for the fitting of the selected vault rooflight system must be provided by the contractor.

Handling

Vault rooflights should always be handled by two people. If vaults are to be mechanically handled they must be secured on pallets and deposited at safe positions on the roof. Great care must be taken with all vaults in windy conditions.

Storage

All vault rooflights should be stored in cool, dry conditions away from direct sunlight, preferably indoors. If outside storage is unavoidable the units should be stacked on a pallet and covered with an opaque waterproof cover draped over timbers placed on the top vault to ventilate the stack and prevent overheating.

Safety

Rooflight installations must comply with the Construction (Design and Management) Regulations 1994.Vault installations in all materials can be made to satisfy the Regulations. Brett Martin CDM specifications and guidance should be obtained for specific projects.

Brett Martin recommend that rooflights should not be walked on under any circumstances.

Maintenance and Cleaning

The general condition of units and all accessories, particularly security of fixings and sealants, should be checked periodically. Abrasive and alkali cleaning materials should be avoided. A mild detergent and a soft rag or sponge can be used to remove surface dirt.
