The Efficient Way to Warm Homes with Glow Heated Glass for Bifold Doors

Glow heated glass is the latest innovative technology to take the glazing industry by storm. It is a specialist glazing that has a conductive coating which generates heat when an electrical current passes through it. This pioneering product can be used as a sole heating source for heating a room, or as an additional heating source for places where extra heating is required e.g., extensions and conservatories etc.

The temperature of Glow heated glass like other primary heating sources is thermostatically controlled. This helps maintain a consistent temperature by turning the glass on and off as needed. This can reduce energy consumption and wastage and lead to lower utility bills.

The average hourly cost is around 9p per Bifold door. Therefore, as an example a 3 door Bifold configuration running for 5 hours per day will cost around £1.35 based on an electricity cost of 25p/kWh.

Glow heated glass has been designed specifically to emit radiant heat rather than convection heat as used in traditional radiators. Radiant heating solutions have many benefits as it heats people and objects unlike convection that heats space. As an example, radiant heat is what makes sunshine feel warm on your skin.

These DGU’s are glazed in a similar fashion to conventional DGU’s. We recommend the electrical work is carried out by a qualified electrician with the product conveniently designed to connect direct to your 240v home mains supply making installations easier and hassle-free. We also provide a comprehensive installation guide with each order.

The Future of Home Heating Solutions

Traditional radiators and gas boilers have been recognised as inefficient and not environmentally friendly by the Government as part of their 2025 Future Homes Standard initiative. In its current format gas boilers and therefore radiators will be banned in new build houses by 2025. Glow Heated Glass with its many benefits will conform to this new legislation.

The electrically heated glass units are thermostatically controlled creating ambient temperatures which are perfect for installation in Bi-folding doors reaching glass surface temperatures of 35-40°C. For the first time, a realistic alternative to radiators, electric fires or underfloor heating systems is available either as the main or an additional source of heating for the home

Available in a range of opening configurations and colours which can fold inside or out, to suit any household.
