For all its benefits, Aluminium is not naturally thermally efficient, which is why Origins Research and Development team have designed the Origin aluminium structure to have thermal polyamide breaks. These limit the heat transfer from inside to out. Sophisticated weathertight seals, and clever glass ensures the weather stay out. This means Origin windows help make homes warmer in the winter and cooler in the summer and this helps reduce your energy bills.
