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.
Superior Gaskets
Our patented double-action gaskets stop gaps from forming thereby preventing heat loss. Memory retentive properties maintain consistently tight weather seals throughout the product lifecycle.
Hinges Designed for Triple Glazing
Triple glazed sealed units are 50% heavier than a double glazed units. Whilst our standard hinges are capable of carrying this additional weight in most circumstances, sometimes a more heavy-duty hinge is required. TruFrame offer the Trojan 'Mega Egress' Hinges as an optional upgrade for all our triple glazed products, providing a true 'fit and forget' level of reliability.
OUR TRIPLE GLAZING PROMISE
Triple Glazing
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!
