   Patio & French Doors



We recognise your new windows and doors make up a large part of the façade of your home and that means aesthetics are just as important as total security. Whatever your requirements, Pro-fix has a style to suit your desire.


Since the introduction of composite doors, and especially ROCKDOOR composite doors, the classic uPVC panel door has lost it's place as the most secure and energy efficient door on the market, however, they are still incredibly efficient and secure doors and can be upgraded in security for peace of mind.


All our windows and doors are environmental friendly and exceed the Government’s environmental and energy efficiency requirements. So you can be assured that you’re receiving the best possible quality of windows.


Available foiled colours:




Irish Oak

Light Oak

Key Features & Benefits


All our doors are fitted with high security multi-point locking as standard and are independently tested to the requirements of PAS:24 2012.


With a unique six-chamber PVCu profile, EnergyPlus can easily achieve an A+ rating, helping you contain and conserve heat within your property.


All our doors offer total versatility with its traditional British style and  offer a wide range of styles to suit every home.


All our doors are available with triple glazing - capable of achieving a U-value of 0.8 with EnergyPlus profile.


All our doors are made from lead-free PVC, which is extruded in Derbyshire at the HL Plastics extrusion plant. The factory  boasts the largest PVC mixing plant in the UK and is one of the largest employers in the region. Continued investment in the facilities keeps Liniar at the forefront of innovation.


The revolutionary profiles used in Liniar doors are far more thermally efficient than traditional uPVC door profiles. By removing unnecessary steel reinforcement, instead developing the latest in multi-chambered profile technology, we make sure the heat stays where it belongs – inside the home.


The profiles used in Liniar doors deliver high energy savings for the homeowner at a cost effective price. Liniar doors are capable of achieving WER (Windows Energy Ratings) A+12 with cost effective double glazing – and a U-value as low as 0.8 W/m²K (with triple glazing).


In addition to saving energy costs for homeowners, Liniar door frames have always been 100% lead-free, well in advance of legislation – better for you and your family. Furthermore, all elements of Liniar uPVC doors are fully and easily recyclable at the end of their life.

All our doors are also fully accredited

It’s important to us to prove our products are backed by the highest standards, and an ongoing testing programme ensures that all systems remain fully compliant – often ahead of legislation. View our manufacturers accreditations below:

Secured by Design


Secured by Design is a police-backed initiative, with this status being awarded to products designed with exceptional security features as their main priority.


Liniar products that qualify to hold this certification are tested to meet the requirements of the Association of Chief Police Officers.


BBA Approval


The BBA (British Board of Agrement) is the UK’s major authority offering approval of construction products, systems and installers.


Their certificates are recognised by architects, engineers and specifiers as an impartial and unbiased review on the performance of products, and Liniar holds a certificate for the whole window system.





This accreditation is part of the British Standards system and shows the product has been subjected to a series of tests, demonstrating enhanced security performance, air and water tightness and wind loading to BS6375 for peace of mind.
