Rooflights |
|
 Rooflights used effectively can promote a naturally light
environment
whilst
not
reducing the insulation, water
proofing or stability properties of the system. Our
rooflights are manufactured from GRP material which complies to BS4154,
ensuring consistent performance. They are
kept in stock in both Class I (fire rated) and Class III grade
(exterior use). In the case of Class I sheets, the fire rating
will be shown by the use of a coloured thread.

The above image
demonstrates the correct positioning in regards to laps.
Notice the higher end of the rooflight is lapped underneath
the cladding. This minimises the risk of water ingress,
allowing the water to run down the roof, over the rooflight. |
|
 |
|
Sufficient lap
should be allowed in both rooflights and roofsheets (shown
above). This is applicable to both single and double skin
construction Appropriate
tapes,
sealants and
fixings should be used to
maximise rooflight performance. |
