What is the difference between double doors and French doors?

Often confused and spoke about as the same thing, although they look very similar, they tend to be used for different things.

Double doors were once a popular commodity for commercial and leisure properties; however, they are now becoming increasingly popular as front doors amongst homeowners due to their elegance and high-quality security measures.

Whereas French doors are typically used for back or side doors, to incorporate light into a living area, or provide easy access onto a porch or garden, double doors tend to be used as front entrance doors for properties due to them offering a better level of privacy, for those opting for double doors instead of a single front door and side lights.

Although of course you can opt to include side lights with any of our double door styles!

Are double doors suitable for keeping energy bills low?

Not only do our double doors look fantastic and are exceptionally secure, but they are also known for being incredibly thermally efficient.

Part L building regulations were updated in June 2022 and all our doors reflect the new changes to create entrance doors as efficient as possible for you.

All double door sets with glazing units require a minimum Window Energy Rating of a B, whereas a double door set with no glazing will automatically get an WER of an A.

Which double doors will you choose? The choice is yours!

Two of our most admired door styles that are also extremely popular as double door sets are the Vermont and the Indiana, two versatile entrance doors that look fantastic with a wide variety of furniture combinations.

Our Vermont door uses four rectangular mouldings, either side of the narrow pane of glass other to create a truly contemporary look for the front of your home. The image on the left/right shows an anthracite grey Vermont as a double door set with dual bar handles for a completely modern look!
