Here are some interesting facts about bifold doors:
- Bifold doors consist of multiple panels that fold in a concertina-like manner, allowing them to open and close with ease.
- These doors are usually made of materials such as aluminum, timber, or uPVC (unplasticized polyvinyl chloride), providing durability and strength.
- Bifold doors offer a wide opening space, maximizing natural light and creating a seamless transition between indoor and outdoor areas.
- The use of double or triple glazing in bifold doors improves energy efficiency, noise reduction, and security.
- Bifold doors are available in various configurations and sizes, making them suitable for different architectural styles and purposes.
- The U value of a door indicates its overall thermal performance, and lower U values represent better insulation properties.
- Investing in bifold doors with a good U value can potentially save on energy bills and reduce carbon footprint.
- Regular maintenance and proper installation are essential to ensure the optimal performance and longevity of bifold doors.
To provide a visual representation, here is a simple table showcasing the U values and corresponding thermal insulation qualities:

1.1-1.4 W/m2KThis is the most cost-effective version that keeps the home well insulated and energy efficient. With a u-value of 1.1-1.4 W/m2K, double glazed bifold doors can also reduce outdoor noise and offer more security because of their increased thickness.
The U value of a bifold door measures how well it insulates a building, with lower values indicating better insulation and reduced heat loss. Current building regulations dictate that a ‘bifold door set’ should have a U value of 1.8wm2k or less for replacement, new builds and extensions. Triple glazed bifold doors typically have a U value of about 0.8, whereas double glazed bifold doors will have a U value of between 1.2 and 1.4. The U-value of the glass is generally better than that of the frame due to glazing and thermal breaks.
The U value of a bifold door measures how well it insulates a building, the lower the U value the better it insulates your home and thus reduces heat loss. Current building regulations dictate that a ‘bifold door set’ should have a U value of 1.8wm2k or less for replacement, new builds and extensions.
Triple glazed bifold doors typically have a U value of about 0.8, whereas double glazed bifold doors will have a U value of between 1.2 and 1.4. The better-insulated a door and its glazing is, the lower the U-value will be.
When looking at how thermally efficient bifold doors are, it is the U-Value that you need to pay attention to. The lower the U-Value of a door, the better. Building regulations state that new replacement doors must have a maximum U-Value of 1.8W/m2k.
There are regulations around U-values which outline that any door set must be at least: 1.4 W/m2K when replacing any existing doors 1.6 W/m2K for new build doors or extension doors All bifold door sets should be 1.4 W/m2K but the lower that number is, the better. Vufold’s Ultra range offers U-values of just 1.0 W/m2K!
When checking the U-value of a certain material: the lower the U-value, the better the insulation of a material. Bifold doors may have two U-values for each major component – the glass U-value and the frame U-value. Generally, the U-value of the glass is better than that of the frame due to glazing and thermal breaks.
