The Liniar brand is synonymous with quality. A high-tech range of UPVC windows, doors, conservatories, decking, fencing and piling systems is designed and manufactured by HL Plastics at a state-of-the-art extrusion facility. Focusing on research, development and design, Liniar pushes the boundaries of innovation. Continued investment in infrastructure, technology and people has brought market-leading success and sustainable growth. Although Liniar produces plastic profiles and puts products through extensive testing, it doesn't actually manufacture finished uPVC windows and doors itself. These are produced all over the UK by a network of specialist window fabricators. Liniar's thermally efficient uPVC window range includes casement windows, bi-fold windows, tilt and turn windows, flush sash windows, French windows, bay windows, bow windows and even a Passive House ready 90mm window system. Liniar fabricators can also supply a wide range of matching doors - from uPVC residential doors to composite doors, and even stable doors - all using energy efficient Liniar plastic profiles. Sliding patio doors feature Liniar's patented ModLok™ exoskeleton; a combined modular locking system offering unparalleled security and strength. The Liniar patio system is one of the most attractive on the market and is light to handle with an 'air glide' motion. Liniar ModLok™ technology also features in its uPVC bi-folding doors, which were awarded a Queen's Award for Innovation in 2017. Unlike other uPVC bi-fold doors, the Liniar ModLok™ exoskeleton prevents expansion and contraction, making them robust and durable - they have been cyclic tested to more than 12 times the British Standard. Liniar has also designed a range of aluminium doors. The Alumina by Liniar range features an aluminium bi-fold door up to 7 panes wide, French doors and single doors in a flush sash style. uPVC conservatories and lantern roofs are also available with many patented features, as well as matching fascia, soffit and rainwater goods. Liniar has designed and manufactured plastic decking since 1999, supplying holiday parks and caravan owners with uPVC verandahs. Liniar uPVC decking features a modular steel framework for durability, expanding into the domestic garden market as consumers realise the low maintenance benefits of plastic deck boards. Decking kits are available direct from Liniar, or through a nationwide network of decking installers. Low maintenance plastic fencing is also popular with consumers. Liniar's uPVC fence panels and posts come in a choice of 11 colours and finishes to suit any garden, with no sanding or staining. Liniar plastic piling is suitable for a variety of applications. uPVC piling and log pile are ideal for flood prevention, soil and water retention.
