KAPO Turn-tilt windows are made-to-measure timber or timber-aluminium windows designed for residential, educational, and public buildings requiring durable, high-quality fenestration with flexible opening options. Manufactured from solid timber scantlings, the windows are available in a range of wood species, including spruce, larch, ash, oak, and meranti, with oiled, glazed, or painted finishes. Timber-aluminium versions combine the warmth of timber internally with a low-maintenance aluminium exterior, supporting long-term weather protection and design flexibility.
The windows can be specified with different glazing types, including thermal-insulation, solar-control, fire-protection, acoustic, safety, and security glazing. Technical features include energy-saving triple glazing, thermally separated external rain rails, aluminium sash-cover profiles, and continuous perimeter seals, helping to improve thermal performance, comfort, and building energy efficiency.
Their sustainability benefits are linked to the use of timber as a renewable material, the potential for regional wood sourcing, long service life, repairability, and improved operational energy performance through high-performance glazing and airtight detailing. KAPO also highlights its use of solvent-free paints and lacquers, and a biocide-free, water-based wood-protection system designed to allow treated timber to be recycled, supporting a more circular approach to timber window production.
