Getting Started

Welcome to the new age

of Composite French Doors

Composite french doors by Rockdoor are a preferred alternative to standard uPVC french doors which have hardly changed in over 2 decades. Composite french doors have the same characteristics of solid timber but with the practicality of uPVC. Extremely strong and robust, the only way through them is with a chainshaw!

Better yet, because we’re Rockdoor Trusted Installers we can guarantee to beat any price!

‘Secured By Design’ uPVC & Composite French Doors

Pro-fix Windows offer a huge range of energy efficient and ‘Secured By Design’ french doors which are the perfect addition to any home.

We offer a choice of 8 colours in our upvc french doors and 13 colours in our Rockdoor composite french door collection. The colours can be used on both exterior and interior – with the option of a different colour for the outer frame. We can tailor our windows and doors to suit the look of any residential or commercial property.

Strong, secure and durable.

Designed with security in mind, our doors come with multi-point hooks, deadlocks and shootbolts. Matching sets of keys for the anti-snap & anti-pick cylinder locks keep things simple for the homeowner.

Less frame, more glass.

Let in as much light as possible.

Cost Effective

Liniar profiles deliver even more energy savings for the homeowner. Liniar window systems are capable of achieving WERs (Window Energy Ratings) of A++, with U-values as low as 1.2w/m²K (DGU) and 0.8w/m²K (TGU).

Technically Advanced

The technology used in many other PVCu door profiles is at least 20 years old. Our door profile (Liniar) was designed completely from scratch in 2007 and is far more technically advanced – built for today’s exacting challenges.

British Made

Our uPVC doors are extruded in Derbyshire at the HL Plastics manufacturing plant, which boasts the largest mixing plant in the UK. Continued investment in the factory and facilities keeps Liniar at the forefront of innovation. Our Rockdoor composite doors are manufactured in Blackburn.
