Rockdoor

GAP

For over 25 years, Rockdoor has been GAP’s flagship composite door brand, with over two million doors manufactured for commercial and domestic properties across the UK.

Known for its innovation in security, thermal efficiency, and style, Rockdoor is the go-to choice for housebuilders looking to offer a top-quality, durable composite door solution.

Why are Rockdoors so popular?

1. Enhanced Security
Rockdoor’s S-Glaze technology is a key innovation that sets it apart from other composite door manufacturers. Unlike traditional doors that use clip-on cassettes to hold the glass, which can discolour and are a weak point for intruders, S-Glaze seals the glass between two Rockdoor skins, making it impossible to remove or tamper with. This improves security by preventing access to the glazing and eliminating a common vulnerability.

2. Thermal Performance
All Rockdoors as standard come with a Windows Energy Rating of at least a C, in line with the newly updated Part L building regulation changes as of 15th June 2022. Rockdoor styles that are unglazed will automatically receive a rating of an A.
Offering the widest range of A rated composite doors on the market, alongside new and improved innovations such as a new aluminium sub-frame, which has allowed us to recently introduce a ‘no bow guarantee’ to its’ customers.

3. Durability and Long-Lasting Performance
Rockdoor is built to last. The high-quality composite materials ensure that the doors won’t warp, bow, or fade. With the introduction of a new aluminium sub-frame, Rockdoor now offers a ‘no bow guarantee,’ reassuring housebuilders of the door's long-term reliability.

4. Customizable Design
With over 25 unique designs, 14 colours, and numerous glass options, Rockdoor offers a wide range of combinations to suit any property. Whether for modern new builds or traditional homes, Rockdoor’s versatile design options make it the perfect choice for housebuilders aiming to meet diverse aesthetic preferences.
