What Are
Composite Back Doors?

Composite back doors are external rear doors made from glass-reinforced plastic (GRP). They are usually made with a solid timber core and insulating foam, ensuring strength, durability and security. They provide an insulating seal to prevent heat loss and draughts, creating a durable, stable door with improved thermal performance.

It is a popular choice among Glasgow homeowners for its resilience and low maintenance. Unlike traditional timber doors that need to be regularly treated and painted, composite back doors only need a wash with soap and water to keep them looking fresh.

These modern doors won’t warp, crack, rot or fade in Glasgow’s wet and cold weather conditions. You can get your composite back doors fully fitted in various colours, styles, and glazing options to ensure you get the perfect back door to leave a lasting impression.

Why Choose Composite Doors?

Composite back doors offer excellent insulation, design flexibility, and long-lasting style, making them the ideal choice for your new back door. A rear entrance door typically gets a lot of heavy use and needs to be able to withstand daily wear and tear. Our GRP composite back doors are designed to provide security and warmth from Scotland’s wet and windy weather.

A few key features of our standard composite back doors include:

  • Low-maintenance: Doesn’t warp, rot or fade when compared to timber or inferior composite door alternatives.
  • Enhanced thermal performance: Keeps your home warm and helps retain heat and improve comfort.
  • Weather-resistant GRP exterior: Protects your home from changing weather conditions.
  • Stylish Options: A wide range of colours to match your home.

Whichever style you choose, you can trust that our durable and secure composite back doors will be the perfect addition to your space. They’re a great option for both traditional homes and contemporary properties.

Homeowners also have the option to upgrade their side panels with double-glazing for added security against forced entry while still allowing natural light to pour in.

Excellent Energy Efficiency & Thermal Performance

Composite back doors feature a solid timber core with insulating foam that provides enhanced thermal performance with a waterproof seal. It helps keep internal heat locked in and external draughts from seeping into the house. This ensures a comfortable and consistent, thermally-efficient home and supports a stronger energy rating for your home.
