altherm™ speciality

Altherm’s™ portfolio of speciality and high performance products offer alternative window and door systems for demanding or distinctive projects.

Each system offers a different level of suitability depending on aesthetic requirement, scale, wind exposure or function. Product ranges offer aluminium joinery, the composite Smartwood™ product, and high thermal efficiency windows and doors to minimise condensation and cold transfer.

Profile shapes generally reflect contemporary preferences for clean, flush surfaces and square edges.
