PVCu Windows
Our advanced window systems feature multi-chambered profiles with thermal reinforcement technology. These windows provide exceptional energy efficiency, achieving U-values as low as 0.8 W/mK while maintaining structural integrity. The innovative design incorporates multi-point locking mechanisms and optional solar control glazing, offering homeowners year-round comfort with minimal heat transfer.
Conservatory Roofs
Engineered with EnergyPlus top caps and patented glazing retention systems, our conservatory roofs deliver superior thermal performance. The aluminium construction with PVCu capping combines slim sightlines with enhanced insulation, reducing heat loss by up to 40% compared to traditional systems while maintaining structural durability against extreme weather conditions.
Garden Rooms
Custom-designed garden rooms feature powder-coated aluminium frameworks with EPDM rubber roofing. These structures withstand hurricane-force winds while providing year-round usability. The modular design allows for multiple configurations including workspaces, fitness areas, and entertainment zones, all incorporating energy-efficient insulation and weatherproofing technologies.
Composite Fencing
Our fencing systems combine galvanised steel reinforcement with multi-chambered PVCu panels. This construction achieves Class 4 wind resistance while maintaining low maintenance requirements. Available in multiple finishes including woodgrain foils, the fencing offers 10-year colourfast guarantees and complete recyclability at end-of-life.
Soffits & Fascias
Manufactured with 20mm thick profiles for enhanced strength, these roofline components feature pre-marked installation guides and integrated ventilation systems. The fire-resistant materials (Class 1Y rating) ensure safety compliance while the foiled finishes provide 10-year colour guarantees matching window and door systems.
Questions
Are Liniar products suitable for listed buildings?
Our heritage range replicates traditional timber profiles while meeting modern performance standards. Many installations have been approved for conservation areas and listed buildings.
How do Liniar windows compare to timber alternatives?
Our systems offer equivalent thermal performance with 70% lower lifetime maintenance costs. The multi-chambered profiles provide better sound insulation than traditional timber windows.
Can I install Liniar products myself?
We recommend professional installation through our approved network. Our systems require specific tooling and certification to ensure compliance with building regulations.
What fire safety ratings do your products achieve?
Our cladding systems achieve D-S3-D1 fire classification, while roofline products have Class 1Y fire resistance. All materials meet UK building regulation requirements.
How does the colour guarantee work?
Factory-foiled components carry a 10-year guarantee against colour fading. This is validated through accelerated weathering tests simulating 30 years of UK climate conditions.
Are your products recyclable?
All PVCu components are 100% recyclable. We operate a closed-loop recycling system where production waste is reprocessed into new profiles.
