ROOF WINDOWS
DOWNLOAD BROCHURES
By choosing the Roto products, you choose a brand having “made in Germany” quality. Our roof windows, solar systems and accessories are made of top-class materials and raw materials displaying convincing properties such as longevity, resistance, appealing appearance, and simple maintenance.
ROTO roof windows that belong to Designo series are equipped with WD thermal insulation pack which improves insulation parameters (technical properties) of the entire window by up to 15%. Such solution prevents formation of condensation as well as formation of heat bridges at the most exposed positions.
Firm connection and good sealing properties are also guaranteed by the use of EPDM seal on the exterior side of the frame as well as the insulation foil that creates vapour barrier. Roof windows with WD thermal insulation packs in their frames do not have ventilation grilles as micro-ventilation is achieved by placing the handle in the specified position.
