Alitherm Heritage 47

About Alitherm Heritage 47


Alitherm Heritage is the ideal solution for heritage applications such as listed building renovations and large scale replica-refurbishment projects where planning constraints are an issue.

The Alitherm Heritage window is designed to be built as a series of horizontal modules which can be stacked using horizontal couplers to form a multi-part window featuring a specially design drip bar between modules.

Alitherm profiles use innovative polyamide thermal break technology which creates a barrier between the cold air outside and the warm air inside. This technology significantly reduces thermal transmittance and enhances the overall U Values.

The Heritage window is also designed to meet the exacting requirements of Document L 2010.
