First, let's look at what they are. Unlike a regular wood or standard UPVC door, composite doors are formed from several materials. The inner section is usually foam for insulation, while for the outer skin you can choose from aluminum-steel, UPVC, or glass reinforced plastic (GRP). The latter material is very popular nowadays owing to its many intriguing properties that make it perfect for use in doors.
They also work to keep out the cold and keep in the heat. And by keeping the warmth in your home, they help lower heating costs. In fact a composite door can retain up to six times as much heat as a wood door does. Meanwhile in summer they keep in the cool and keep out the warmth.
Other than the inner foam, these doors have other insulating enhancements in the form of high efficiency sealing systems to further keep out sound and the elements.
