How exactly do thermally broken windows work?

Most windows are made from standard aluminium frames, which carry their own range of incredible benefits but ultimately lack the ability to insulate your home from harsh temperatures. Thermally broken windows, on the other hand, are specifically designed to keep the heat and the cold out, maintaining your home at a comfortable temperature all-year round. Insulated using state of the art glazed technology, this durable, long-lasting solution is perfect for those households that are located in particularly cold or hot areas. On top of its insulation benefits, our thermally broken windows are simply a gorgeous addition to any space. Simple, clean and effortlessly functional, they allow you to make the most of the natural light. Our sliding system also makes it easier than ever for you to open the doors either one by one or completely, by stacking them on top of each other. This is perfect for those times when you want to increase your space or combine indoor to outdoor living.
