Energy efficiency

Minimise waste on a property

Research has proven that poor quality uPVC and ill-fitted products are responsible for up to 20% of a home’s total waste. Our Liniar profiles have been intelligently designed to minimise this.

100% Recyclable

Our uPVC windows hold fantastic energy saving values, without the use of harmful materials such as lead and steel. This makes our uPVC frames kinder to the environment, as well as being 100% recyclable.

Tough wearing

As a material, uPVC is an incredibly energy efficient, exceptionally workable and tough! Our patented design comes complete with glazing flippers and thermal dams to help minimise cold air ingress and prevent water leaking through.

Multi Chambered

The intelligent frame is constructed from a series of size optimised chambers. These chambers trap pockets of warm air, creating a thermal barrier within the frame. This prevents the cold air from transferring into the property.

Why Choose TruFrame for your Liniar Windows?

As an energy efficient manufacturer, TruFrame are conscious of providing products that are not only energy efficient but are also kind to the environment.

Key Features

If you would like to find out further information about the energy efficiency of our uPVC profile, feel free to contact our in-house team of uPVC experts at any time. We’re here to help you choose the perfect profile for your project. Below are key features of our energy efficient products:

A+14 WER

The Liniar window system is capable of achieving a WER (Window Energy Rating) of A+14 using a double glazed sealed unit. We are not aware of another window profile system that can match this extraordinary level of energy efficiency.

More Thermally Efficient

The revolutionary Liniar window system uses the very latest in uPVC profile technology. Its multiple size-optimised chambers are specially designed to lock in the heat and break up mini convection currents.

100% Lead Free

Better for the environment, Liniar frames have always been made from completely lead free materials well in advance of legislation. Moreover, all elements of the Liniar profile are 100% recyclable.

Our Commitment to Recycling

Our uPVC windows are extremely robust and do not need expensive steel reinforcement. They are therefore 100% recyclable making them a truly environmentally friendly product.

Incredible U-values

The Liniar window system, utilising a 38mm triple glazed unit, can achieve U-values as low as 0.9 W/(m²-K), and an A+25 WER!

38mm Glazing Bead

Specifically designed to accommodate a 38mm triple glazed unit.

Our Triple Glazing Promise

Most UK window systems are not designed for triple glazing. Consequently, installers are forced to fit much thicker triple glazed unit into a profile designed to take a 28mm unit!

The result is that fitters struggle to bead windows, with the units being forced under such pressure they fail, with expensive service calls virtually guaranteed.

Not with TruFrame! The Liniar system has a triple glazing bead that is specifically designed to allow 38mm units to be easily accommodated. It is simple and straightforward to use and eliminates costly service calls!
