8 Reasons to Choose Liniar

Strong and Secure

Liniar’s range of windows and doors is tested to the latest security standards, with PAS24:2012 enhanced security performance passed with flying colours. Built-in security features mean that Liniar frames hold Secured by Design (SBD) status. SBD is a police backed initiative that works to ‘design out crime’ when it comes to home improvement solutions.

Liniar products are fitted with high-security, multipoint locking systems that have been designed to engage at different parts of the frame. This means that security is kept consistent across the whole frame, so you won’t have to worry about there being a weak spot at any part of the window that could be used as a leverage point to gain access to your property. It’s important that these locks are integrated into the frame to ensure they can’t be used to bypass the security of the frame.

Comprehensive Colour Range

The whole Liniar range is available in a wide choice of attractive colours and finishes. With an easy clean, low maintenance finish, Liniar’s coloured foils give the appearance of woodgrain and won’t scratch or peel off. This means that you’ll be able to enjoy all of the benefits that the timber aesthetic is able to bring without having to miss out on the modern innovations that are going to make a Liniar window a worthwhile investment for your home.

This also means that your new window or door is going to serve as an accurate reflection of your tastes as well as a complementary new addition to your property style. Whether you’re looking for something that is going to stand out, or you want something that is going to blend in, then you’ll be able to choose exactly what you need. Simply speak to your nearest Liniar installer to see what they can offer you for your home.

Fully Tested

To ensure peace of mind that Liniar products will endure the rigours of daily living, Liniar carries out weather and security testing, and has also invested in a robot for cyclic testing. This means that you’ll be able to rest assured that you’ll be bringing lasting quality to your home without compromising on style. A Liniar product will be able to bring a standard of quality to your home that will continue to deliver long after the installation has been carried out. Why settle for less when you don’t have to?

More Thermally Efficient

By removing unnecessary steel reinforcement and developing the latest in multi-chambered profile technology, Liniar’s revolutionary profiles (frames) are far more thermally efficient than traditional uPVC window profiles – keeping the heat inside your home and your energy bills lower. With these factors in place, you’ll be able to keep the warmth inside your home for a longer period of time.

As mentioned, this means that you could find that you end up saving money on your heating costs as you rely less frequently on your heating to keep your home at the optimum temperature. Consequently, this also means that you could end up reducing your carbon footprint too as you use less energy to keep those winter winds at bay. All in all, Liniar products are a fantastic way for you to bring sustainable, industry-leading quality to your home.

Less Frame, More Glass

Liniar products have been designed with ultra-slim sightlines, allowing in maximum natural light and resulting in more attractive windows and doors. All of this is achieved without compromising on structural integrity or performance. This means that you’ll be able to make your home a bright and spacious place to be without having to worry about missing out on industry-leading standards.


Liniar profiles come with a 10 year guarantee against discolouration, warping and cracking. This is thanks to the premium grade materials that are used in their manufacturing process, which ensures they need minimal input from you to keep them looking and performing at their very best.

This is important when it comes to ensuring they offer you lasting quality for your home, as a rotting or twisted frame is going to bring a host of security and weatherproofing problems. All of which is going to have a negative effect on how much comfort they are going to be bringing your property.

Made in Britain

The Liniar range is designed, manufactured and supported by an innovative team with more than 500 years of window industry experience.

Eco Friendly

Furthermore, Liniar frames are better for the environment. They have always been 100% lead-free, well in advance of legislation, and all elements of a Liniar window are fully and easily recyclable at the end of its life.

Don’t worry though, due to modern recycling techniques these products don’t lost their quality when they are recycled. This means that the best of both worlds can be achieved when it comes to ensuring they offer sustainability and high standards of performance. Speak to your nearest Liniar installer to bring the best of these designs to your home a way that isn’t going to be detrimental to the environment.
