Security Doors, a division of ASSA ABLOY UK, the global leader in opening solutions, has tested a new high-efficiency thermal door offering excellent insulation.

The thermal door has achieved a U-Value of 1.6 W/m²K in both single and double door configurations, exceeding thermal energy efficiency standards referred to in Part L Building Regulations guidelines, which require external pedestrian doors to achieve a U-Value under 2.2 W/m²K.

The U-Value refers to the amount of heat transferred through a material. A slow transfer of heat leads to a better insulating value, and a lower numbered U-Value. If required, the thermal door can be upgraded to achieve a higher thermal efficiency U-Value of 1.3 W/m²K, preventing heat loss further.

The thermal technology is concealed in the door’s interior, making it door the same thickness and frame appearance of a standard door, so it is aesthetically appealing for both commercial and residential use.

Brian Sofley, Managing Director at ASSA ABLOY Security Doors said: “ASSA ABLOY is well-known for reliable, high performance products, and our new thermal door is no different. Suitable for use in private and commercial properties, occupants can benefit from its high insulating value.

“On average up to 20% of heat loss is due to poorly insulated doors and windows. Our advanced thermal technology will contribute to the energy efficiency of buildings as well as saving the bill payer money.

“Taking the correct measures to insulate a building, will help to create a comfortable working environment.”

The thermal door will be fully CE marked, ensuring validity to be sold throughout the European Economic Area. Covered by a harmonised European products standard or a European Technical Assessment.
