The Alitherm Heritage profile offers the ideal solution for heritage applications such as listed building renovations where planning regulations demand a like-for-like replacement window with optimum thermal performance. 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 designed drip bar between modules. This modern, but vintage looking alternative gives character to a building and are a treat to look at.
