Why composite doors appeal
Warmer entrance doors
Low stated U-values help reduce heat loss at one of the busiest and most exposed openings.
Strong security features
A solid build and quality hardware help the door feel secure every time it closes.
More design freedom
Glazing, colour and hardware choices let you shape the look without losing performance.
A front or rear door that feels solid
A good entrance door should shut with confidence, hold heat better and look like it belongs on the property rather than like a thin afterthought. Composite construction brings together thermal performance, security and a more substantial look, which is why it suits both front and rear upgrades so well. With Smyth Window Systems, you can choose from oak-replica woodgrain finishes, concealed hinges, wood-look glazing beads and a wide range of decorative designs, so the finished door feels considered rather than generic.


Pick the details before the door is made
The best result comes from getting the practical choices right at the start. We help you work through colour, glazing, hardware, opening direction and whether the door is best suited to a main entrance or a rear access point. Through Smyth Window Systems, the glass is triple glazed and paired with Edgetech Warm Edge seals, while door glass is produced in-house for direct control over quality. Once the final design is agreed, we move into measuring, manufacture and fitting with the details already settled.
Frequently asked questions
What makes a composite door thermally efficient?
The door slab, glazing and sealing details all matter. These doors feature triple-glazed glass with a 0.7 U-value, Edgetech Warm Edge seals and a stated complete-door U-value of 0.205, giving clear thermal figures to compare.
Can I choose the glazing and hardware details?
Yes. We work through colour, glazing, hardware and opening direction before the order is finalised. That helps you match the door to the entrance, the level of privacy needed and the overall look of the property.
What warranty comes with a composite door?
Composite doors carry a 10-year supplier-backed warranty. That gives you product cover on a door that is designed to combine a solid appearance, security and useful thermal performance in one unit.
