ALUNA Aluminium Casement Windows — Contemporary Build
About this project
Anthracite ALUNA aluminium casement windows installed across a contemporary apartment building in Surrey. The super-slim sash profile of the ALUNA system was specified to maximise glass area and deliver the clean architectural lines the project demanded. Each window is Energy Rated A and PAS24:2022 certified — the benchmark for security on any residential project. The thermally broken construction achieves a U-value of 1.4 W/m²K, exceeding current Building Regulations requirements comfortably.
