Energy-Efficient Windows
Our PVCu windows feature multi-chambered profiles and EnergyPlus top caps that reduce heat transfer. Tested to British standards, they maintain comfortable indoor temperatures while lowering energy bills. Available in various styles including casement, tilt-and-turn, and heritage designs.
Conservatory Systems
Custom conservatories with aluminium frames and PVCu components combine thermal efficiency with aesthetic appeal. Available in Victorian, Edwardian, and modern styles, featuring self-cleaning glass and patented weatherproofing technology for year-round usability.
Garden Rooms
Thermally insulated garden rooms with powder-coated aluminium frames and EPDM rubber roofs withstand extreme weather. Designed for multiple uses including home offices, gyms, or entertainment spaces, with optional electrical and plumbing integration.
Composite Fencing
Low-maintenance fencing systems with galvanised steel posts and multi-chambered PVCu panels. Resistant to storm-force winds, available in woodgrain or composite finishes with 10-year colour fade guarantees and full recyclability.
Roofline Products
20mm thick fascia boards and fire-resistant soffits extruded to precise tolerances. Featuring pre-marked installation guides and secret fixings, they provide durable, low-maintenance roofline solutions that match Liniar window systems exactly.
Questions
Are Liniar products suitable for listed buildings?
Yes, our heritage window systems replicate traditional timber designs while meeting modern performance standards, making them suitable for conservation areas with appropriate planning permissions.
Do your conservatories require planning permission?
Most installations qualify as permitted development, but we recommend checking current regulations regarding size restrictions and boundary proximity before installation.
How do your PVCu products handle extreme weather?
All products undergo rigorous testing for hurricane-force winds (up to 154mph), heavy rainfall, and snow loading, with documented performance certifications available through suppliers.
Can I install Liniar products myself?
We recommend professional installation through our approved network due to technical requirements for structural integrity and compliance with building regulations.
What sustainability measures do you implement?
Our zero-landfill policy recycles 100% of production waste, and all products contain recycled PVCu while remaining fully recyclable at end-of-life through our take-back scheme.

We had some Liniar bifold doors supplied as part of our new conservatory. So very impressed, not only with the doors themselves which are glorious, but the customer service has been second to none. Unreservedly recommend!

We install Liniar frames as a company. One of the best manufacturers for uPVC windows. Been using since 2011, great quality and aftersales. Highly recommend to any one considering upgrading their windows.

As a supplier of signage to Liniar, my firm , Lemon Signs has experienced at first hand the commitment to quality and attention to detail that all the previous 5 star reviews have referenced. As a client, they are accommodating, clear, responsive and fair. In particular, our primary contacts, Sue Davenport and Charlotte Curtis, have been exemplary in their dealings with us.

Ive had bi folds for approx 8years. Last year a bottom hinge snapped - the door is used every day. Liniar sent new improved hinged to be fitted by their representative. Not only did he do that, but he replaced the door insulation for the improved product and fitted new brush insulation too. The doors had been given a complete overhaul. Just before 'lockdown', in the searing heat the doors had begun to expand and were catching, but I knew Liniar wouldn't be out for some time. As soon as lockdown restriction where released, without me calling them, they rang and booked the rep in again. He came

After a totally useless independent installer had completely ruined my conservatory roof, I contacted Liniar to ask for their assistance.
Liniar and particularly Tony Basile, were amazing, taking the time to visit my property to assess the situation, advise on the best way forward and supply everything to correct the roof. The best customer service of all time, thank you
