How composite doors are constructed

Our GRP Composite doors are produced to the highest standards, ensuring durability, strength, and security. The composite front door has a subframe made of solid water-resistant polymer material that is reinforced with laminated veneer lumber. The GRP skin is then glued to the subframe, while the door’s core is filled with high-density foam. Water-resistant polymer rails protect the door’s core from damage and water.

The high-impact resistant GRP skin makes your composite front door look excellent for years. The composite door core contributes to the door’s thermal efficiency while also lowering sound. This makes it one of the most thermally efficient doors available.

All of our composite doors are A+ rated, which keeps your home warm in the winter and cool in the summer while saving you money on energy bills over time.
Our trained team is here to assist you in selecting the best door for your home. We’ll walk you through the entire process, from glass and trim options to colours, designs, and accessories.
