Winter gardens

The structure of a winter garden consists of glue-laminated spruce timber with a colourless base-coating, which is finely smoothed and can assume every colour. The glazing of the lateral parts consists of double heat protection glass, the glazing of the slanted roof of a heat protection safety insulation glass (laminated safety glass in step construction) with a U value of at least 1,1 W/m2K. 


Special profile systems guarantee a controlled drainage. The coverings of the rafters and glass joints in aluminium profiles are available in any RAL colour.

Old wood

Old wood can have been used for a house construction for the first time between 100 and 500 years earlier. It is very hard, dry, and shrinks only very little. If in its use the structural wood preservation is considered, for its long lasting no coatings or chemical preservations are required.


Old wood is often used for outside panelling, facings, floors, wall boarding, interior equipment, doors, and roof trusses.


The manifold applications of old wood in new buildings, restorations, and interior constructions are endless.
