Bi-folding doors FAQ's

If you have any questions about aluminium bi-folding doors look no further - we have answered all your common questions!
1. Are bifolding doors thermally efficient?
Yes! Our bifolding doors are manufactured using a top-quality aluminium system that benefits from a thermal break for maximum thermal efficiency. This means that, depending on glass choice, our bifolds can achieve an impeccable U-Value of 1.4.
2. Do bifold doors add value to a home?
Bifold doors are most desirable due to their ability to flood your home with natural light. On top of this, they’re practical for day-to-day use as an easy access to your garden. Along with a whole host of other benefits, these are what can make bifold doors a great addition to any home, and most certainly a good investment.
3. Do I need planning permission to get bifolding doors?
In most cases, if you’re installing bifold doors into your home you will not need planning permission. However, if your property is a listed building or the bifolds are forming a part of a new extension, always ensure to check with your local building regulations first.

Equally, if you are based within a conservation area, check with your local council before going ahead with the installation.
4. How do I measure for new bifolds?
To measure accurately for your new bifolds, follow the steps outlined below:

1. Take a tape measure and record the height of the opening in 3 places; at the left, middle, and righthand side of the opening from the exterior.

2. Repeat step one, this time with the width of the opening.

3. Take the smallest measurements for both the height and width, then deduct 10mm from each to allow for tolerance when installing.

4. Lastly, make sure that the aperture of the opening is square by taking the measurements of the diagonals and ensuring they are the same length.
5. What kind of lintel is needed for bifold doors?
As bifolding doors are not weight-bearing, you will need to have a supportive lintel that is either wooden, concrete, or steel cavity.

As a general rule of thumb, you should also ensure that the lintel has at least 150mm bearing at each end, and that the length of the lintel is at least 300mm more than the opening width.
6. What size of bifolds do you offer?
7. What is a traffic door?
8. What colour can I have my bifolds?
Our bifolds are available in three popular colour options: black, white, and anthracite grey. We even offer the option to choose different internal and external colours, so you can select whatever colour combination your heart desires for the inside and outside of your bifolding door.
