Aru 78 MODERN EX

The Aru 78 MODERN EX is a square-profile, outward-opening wooden window designed for energy-efficient and modern buildings. A triple-glazed unit is installed in the frame profile, ensuring high thermal performance.

The lower part of the multilayer deep-impregnated laminated timber frame is protected with an aluminium drip cap. To reduce thermal bridging at the edge of the glazing unit, we recommend using a unit with warm-edge spacer bars (e.g. CHRU, SWS, etc.).
