Skylights for Flat Concrete Roofs
The following skylights are designed for flat concrete roofs. They need to be incorporated at the design phase of the roof. In addition, it is advisable to find out the standard sizes before casting the slab. It could be that the hole left is 10mm bigger than a standard size, which will then require a custom fit which will be more expensive.
Note: It is not a good idea to install skylights in existing precast slabs. Reinforced concrete roofs are designed to span a given distance and any attempt to cut them could be disastrous, they could fail. Fabtec will only install a skylight into an existing reinforced concrete roof after a qualified structural engineer can guarantee the that the slab can take it. In addition, the cutting of the roof is very expensive, requiring diamond head cutters etc.
No maintenance option
We also have a No Maintenance option where the base fits over the upstand. This skylight will also have a five-year guarantee. These are similarly priced per square metre, but you pay more for the skylight because it is bigger. They are maintenance free as they will not require the waterproofing to be repainted every 3 – 5 years as the others do, and are well worth the extra expense.
Custom Glass Skylights
Typically, glass square, rectangular or radial pyramids can be made to any size, ie custom made. Costs are similar to the moulded acrylic skylights which come only in standard sizes. So, if you have an odd size that is required, it is better to opt for a custom-made glass skylight.
