Why Choose an Advanced Roofline Composite Door?

Strength and Security

We’ve already mentioned how great composite doors look, but did you know that they also provide high levels of strength and security. Constructed from high-density polyurethane foam, timber and glass-reinforced plastic outer skin, our composite front doors are extremely durable.

Their lightweight material, GRP also has a higher strength ratio than mild steel which makes this door design virtually impact resistance. As composite door suppliers we ensure that our product is highly secure. Each fitted with a multi-point locking system and optional cylinder locking mechanisms – tested to Pass 24 requirements – for the ultimate reassurance.

All of our composite doors are fitted to a steel reinforced door frames. With a range of door threshold options available, including low/flush thresholds for unrestricted access and enhanced weather-resistance.

Energy Efficient

Another reason to choose a composite door for your home is energy performance. They’re an excellent way to save energy and this is all down to their core material polyurethane foam, which offers outstanding levels of heat insulation and thermal efficiency.

Multi-chambers within in the door frame can further increase efficiency by acting as a barrier against heat loss. For ultimate energy savings we recommend choosing a double rebated door fitted with 50mm triple glazed units. Our triple glazing features high-performance coated glass which will reflect heat back into your home improving thermal energy and limiting wastage.
