Liniar

Who we are

Liniar is a leading manufacturer of uPVC windows, doors, outdoor products, and conservatories. Based in Derbyshire, we pride ourselves on producing industry-leading, quality-assured supplies for residential and commercial use. With over 500 years of industry experience, we design, manufacture, and test our products at our modern extrusion facility to ensure the highest standards of quality and performance.

What we Do

Our range of uPVC windows and doors is one of the most technically advanced on the market. Designed from scratch to incorporate the latest developments in uPVC window profile engineering technology, our products are highly energy efficient. The multi-chambered design of the Liniar profile ensures superior insulation, resulting in cost-effective double glazing that can achieve an A+ energy rating. Our windows are lead-free, fully recyclable, and available in various styles and designs to suit any property.

In addition to windows and doors, we also offer decking and fencing solutions that are popular for holiday homes and gardens. Made from lead-free uPVC with up to 86% recycled content, our decking boards are maintenance-free, durable, and environmentally friendly. Our balustrade system features a sculptured range in a variety of colours and finishes, providing an attractive and long-lasting fencing solution.

Furthermore, our piling and retention systems are used across various industries and applications, offering a lightweight and cost-effective alternative to traditional steel piling. Made from 100% recycled PVC, our plastic piling is versatile, strong, and eco-friendly. Whether for construction, landscaping, flood defense, or erosion prevention, Liniar piling provides a reliable solution for water and soil retention.

We also provide a range of building products exclusively available through Liniar fabricators. From foam trims to sealants, cleaners, fixings, and accessories, our building products are designed to complement our windows and doors perfectly. With color-matched foam trims and a single point of guarantee for the entire installation, Liniar offers a seamless solution for window fitters and installers.
