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 COMBINA: This wood/aluminium window system has a frame thickness of 99 mm, triple-glazing and break-in resistance as standard features, and is therefore one of the strongest in the KATZBECK range.
COMBINA 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.
