When making the decision of upgrading your existing door you can be assured that when choosing a 70mm double rebate door from  Trade Windows 4U you will have an entrance door with leading edge performance. 

The main feature of our twin rebate doors is the 70mm door slab as opposed to a 44mm slab used in traditional composite doors. The primary benefit of the increased slab size is that it provides a higher lever of thermal efficiency. When tested against a 48mm solid timber composite door, the 70mm slab was 19% more thermally efficient. The three images below demonstrate this feature as the darker the blue, the less heat is being lost.
