Bifold doors benefit from large expanses of glass panels. 

However, due to them being mainly glass, people often think they make the home colder in the winter months. Moreover, glass can be draughty and can infiltrate cold into the home. Despite this belief, bifold doors allow natural light into the home all year round, meaning the home is warm and cosy in the cold months. Hence, thermally efficient bifold doors are advisable for any home. 

Throughout this article, we will discuss the necessary U-value of bifold doors and why you should choose bifolds for your next project.

How To Check Thermal Efficiency

One way to check the thermal efficiency of a product is to look at its U-value. The U-value measures how well a product retains heat. Hence, the lower the value, the better – the more thermally efficient it is. Regulations today suggest that a window or door needs to have a U-value of 1.6 W/m2K. 

Why Choose Thermally Efficient Bifold Doors?

Bifold doors have improved in recent years due to advances in technology and double glazing. Hence, not only has the quality of the glass improved but so has the design of the doors themselves. In turn, this means that bifold doors provide thermal protection and ensure that heat doesn’t escape from the home. 

Furthermore, bifold doors are weatherproof and prevent draughts, rain and cold weather from affecting the temperature of the home. Thermally efficient bifold doors can lower energy bills for homeowners too! 

Wooden bifold doors need to be FSC certified to ensure they are performing to their optimum level. Aluminium bifold doors are more secure and help to protect the home from the winter weather. 

As bifold doors are more efficient thermally than patio or sliding doors, the energy efficiency of the home will also increase. Hence, bills will reduce and the environment will benefit from them too!
