The SolTech Sigma is installed in accordance with traditional methods for tiled roofs at a slightly higher t for that of a traditional roof.
In the case of re-roofing, the old roof cladding i taken down, including battens. Once the roof is cleared of tiles, nails and battens, the installation of the SolTech Sigma system may begin.
Underlay
In the same way as with a traditional roof we begin with the underlay. If the roof was recently re-roofed (less than 10 years) you may be able to keep the old underlay, check the condition of the underlay. Otherwise replace the underlay with a new one in accordance with your building regulations.
Battens
Traditional battens are installed. The only difference is that our batten distance may differ and our dimension of the battens are somewhat different.

Insulation
For optimal efficiency and function a layer of insulation is placed between the battens. The battens work both to reduce losses but also to protect the underlay from exposure to excess temperatures.
Absorbers
Our especially designed absorbers are placed between the battens onto the insulation. The absorbers are the result of extensive research and development at SolTech Energy for optimal efficiency, installation and production cost.
Collection manifolds
The absorbers are connected to manifolds that collects the energy from the absorbers. The manifolds are placed at the side of the SolTech Sigma System and are also covered by the glass roof tiles. The collection manifolds are connected to insulated pipes connecting the SolTech Sigma to the solar coil in the accumulation tank.
The collection manifolds are prefabricated and supplied by SolTech Energy but can also be tailored for specific installations.
The GlassRoof Tiles
The Glass roof tiles are the result of several years of research here at SolTech Energy and is made of high transparency glass with a low level of iron oxide. The tile is a Double-S profiled tile very similar to traditional concrete tiles used in the Nordic and other countries.
The SolTech Glass Roof Tile has superior durability against erosion and sunlight and has a life expectancy far grater than that of any traditional roof tile. Tests conducted at The Swedish Cement and Concrete Research Institute (CBI) show that the glass roof tile can withstand pressure 7 times the requirement for that of a concrete roof tile.
An additional feature of the SolTech Glass Roof Tile is that it allows snow to easily glide off the roof in winter time. Since the surface is smooth, with a little help of the sun, the snow glides off the roof by itself.
Laying of Glass Roof Tiles
The tiles are laid on the roof and battens much in the same way as traditional concrete tiles. The tiles are packed in bundles of 5 for easy and ergonomic handling. Laying begins in the lower right hand corner.
