A couple in harmony will spare both sides’ energy.
Klaus Ender, Poet
The particular wood thickness and the immense stability of the casements, frames and fittings deliver convincing arguments for COMBINApassiv: This wood/aluminium window system has a frame thickness of 111 mm, triple-glazing and break-in resistance as standard features, and is therefore the strongest in the KATZBECK range. COMBINApassiv is also suitable for
passive houses, as it satisfies the strict thermal insulation standards required in energy-efficient construction.
COMBINApassiv is a highly durable product that guarantees a comfortably warm home and a pleasant sense of security. What’s more, it provides all the benefits of wood/aluminium systems and possesses an ideally proportioned design.
