The Rockdoor Ultimate Composite door range

Composite doors are a favored choice among homeowners for their robust security, energy efficiency, and low maintenance. Unlike traditional wooden, uPVC, or metal doors, they require no painting or varnishing and are easily cleaned with soap and water.

These doors combine materials like GRP, timber, and PU foam to enhance insulation, keeping your home warm and reducing energy costs. However, not all composite doors are created equal. Rockdoor composite doors stand out by using a high-density core that is 60% stronger than standard models, applicable to all their front, back, French, and stable doors. This makes them a visually appealing and practical option for home security and energy efficiency.

Composite doors are the superior choice for home exteriors, providing top-notch security and thermal insulation over timber, uPVC, and GRP doors.

Rockdoor, a leader in the industry, has developed composite doors that surpass others in security and thermal performance. Their doors are proven to be 35% stronger than standard GRP doors, making them some of the most secure in the UK.

From the beginning, Rockdoor has been pioneering industry standards, achieving the prestigious Secured by Design accreditation for all our composite doors, including our French doors—a first among door manufacturers.

We continue to lead with innovations in door security and were also the first to advocate for energy ratings on doors. Our efforts culminated in Rockdoor being the first to receive an A++ energy rating, confirming our doors as the top choice for enhancing both security and thermal performance.
