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. |
