Rooflight cassettes for
C300 sandwichpanels: |
|
|
|
| |
 |
Inside and outside polyester sheet in 450 gr/m2 with Melinex-longlife
protection film |
|
| |
|
Melinex-longlife protection film reduces ageing of the sheets as
a result of UV-radiation and improves smoothness of the
finishing so less |
|
| |
|
dirt will be held by the surface |
|
| |
|
Rooflights are factory assembled with spacers at each purlins
center, lengthwise, impregnated and waxed ribs are inserted to
improve |
|
| |
|
the strength of the cassettes |
|
| |
|
For span larger than 2000 mm, an extra rib will be applied in
the middle of the cassette |
|
| |
|
Lateral sealant |
|
| |
|
Maximum length 12000 mm - additional price for lengths shorter
than 3000 mm |
|
| |
|
Fasteners in each top of trapezium with large spacer - see
assembly manual |
|
| |
|
Fireclass DIN-B2 (Melting temperature > 140º C) |
|
| |
|
Some condensation may build up in the cassettes with large
climate- or temperature variations between inside and outside,
as soon as |
|
| |
|
temperature difference falls, this will disappear |

Rooflights on southern roofs will result in much more
overheating in summer - see picture |
|
| |
|
We also
supply ridge-rooflights with special polyester (so thermal
broken) stands to put the polycarbonate and aluminum bows in |
