Rockdoor Composite Doors

GAP

Manufactured for over 25 years in the heart of East Lancashire, Rockdoor is GAP’s flagship composite door brand, with over two million doors manufactured for both commercial and domestic properties in the UK.

The composite door manufacturer is synonymous with security, thermal efficiency, and style thanks to years of built-up reputation, due to their innovations in manufacturing and beneficial designs to keep homes and properties around the UK safe and energy efficient.

Rockdoors’ feature the innovative S-Glaze technology, the only composite door manufacturer to use such a manufacturing process, which not only improves the security of the door but also the energy efficiency for the entire property.

This substitutes the traditional method of using clip-on cassettes to hold the glass in place, which tend to age and discolour over time, as they are often not manufactured out of the same materials as the uPVC door skins.

Not only can they become aesthetically displeasing over time, but they are also a susceptible point for breaking and entering properties, because of their design, making them easy to pry open.

S-Glaze is the process of sealing the glass unit between two Rockdoor skins, so that the glazing cannot be replaced or removed in its lifetime, offering a whole host of benefits to homes:

• An increased thermal efficiency due to their being no opportunity for drafts to enter a property via the glazing.
• Increases property security as the glazing cannot be removed to allow intruders.
• Longer lasting door substrate colour which won’t fade or discolour, like clip-on cassettes, keeping properties looking newer for longer.
