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.

Tilt and Turn Windows

Tilt and turn windows are the latest and most innovative profile option available to homeowners in Buckinghamshire and surrounding areas. As their name would suggest, these profiles open from the side of the frame like a normal window as well as tilting forward with the frame. They combine visual appeal with modern functionality, making them a superb renovation option for every homeowner.

Liniar are our designated tilt and turn window supplier. They are the leading name in this industry and provide us with high quality extruded uPVC profiles. As a bespoke glazing specialist, we then craft and fit the glazing for these windows in-house, ensuring it’s of the highest quality, without fail. With this, your tilt and turn windows deliver the best possible performance.

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.
