Energy Efficiency & Environmentally Friendly

100% Lead-Free

By working with Liniar products, our entire window and door range is fully lead free. There is no lead used in the profile itself or throughout the actually manufacturing process. Such a unique, eco-friendly process is unheard of with other manufacturers.

Lower Carbon Footprint

Both the profile and the glazing we use offers fantastic thermal insulation as standard. With improved heat retention, you may not need to have your heating on as high in winter. Doing so can see you improve your carbon footprint over time.

100% Recyclable

The uPVC profile used for our Liniar windows and doors is made from fully recyclable materials. Despite this, they still deliver superb thermal and security performances across the board, standing toe to toe with new profiles from other manufacturers.

Energy Efficient Profile

All our Liniar uPVC windows and doors are fantastically energy efficient. The multi chambered uPVC profile retains the maximum amount of heat, adhering to the latest regulations. Your home will sit at the optimal temperature during winter.

Sliding Sash Windows

If you live in an older property here in Buckinghamshire, new sliding sash windows are a fantastic renovation option. They authentically replicate the vertical sliders of old, offering you a modern uPVC home improvement disguised as a traditional timber product. You can fit them to an older property, improving its overall performance without compromising on the period charm.

Sliding sash windows operate on a vertical sliding mechanism. This allows the bottom half of the sash to slide vertically, sitting parallel with the top half when opened. These types of window are almost exclusively fitted to older properties here in the Buckinghamshire region. However, with Victorian houses more popular than ever, the demand for new vertical sliders has reached its peak.

Maximum Security

Hidden Attack Lock

Ultion locking systems come with unique technology that will detect if an intruder is attempting to gain unwanted access through the window or door. When activated, a hidden firing pin secures the central cam, fully preventing any forced entry into your home.

£1,000 Security Guarantee

The Ultion locks fitted to your new windows or doors are supported by a financial guarantee. If an unwanted intruder does manage to break-in, you’re entitled to compensation of up to £1000. The chances of this ever happening is extremely thin, however.

Drill Protection System

20 hardened steel pins are fitted into an Ultion lock as standard. They are precisely and individually positioned to specifically prevent an unwanted intruder from using an electric drill to get into your property. No other lock on the market can offer the same.

Secured by Design

Our windows and doors can reach Secured by Design requirements when they are fitted with Ultion locks. A scheme supported by the UK police, it lays out the minimum standards for competent home security. Our products comfortably exceed these.
