What is the difference between double doors and French doors?
Often confused and spoken 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 as back doors or side doors, to incorporate light into a living area, or provide easy access to 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 Rockdoor double doors completely secure?
Double doors were once seen as an easy target for burglars given the difference in locking methods to a traditional entrance door.
Rockdoor tore up the rule book completely to create the most secure set of double doors on the composite door market, which resulted in us becoming the first manufacturer to achieve the Police backed ‘Secured by Design’ accreditation for our double doors.
Our efforts paved the way and set high standards for double door security across the composite door market, which we still place at the forefront of our designs to this day.
Already synonymous with security and style, Rockdoor double doors come in a variety of options to keep your home looking refined and secure, choose from a glazed or solid door style, with or without side frames!
We have the utmost confidence that potential intruders will be unable to gain entry to your property by picking or manipulating the lock and that all our Avocet 3* Cylinders come with a £2,000 security guarantee.
Are double doors suitable for keeping energy bills low?
Not only do our composite 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 efficiently 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 a WER of an A.
Which composite double door will you choose?
Two of our most admired composite door styles that are also extremely popular as composite double door sets are Vermont and Indiana, two versatile entrance doors that look fantastic with a wide variety of furniture combinations.
Our Vermont door uses four rectangular mouldings, on 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!
One of our solid door styles, our Indiana doors feature vertical mouldings which run nearly all the way from top to bottom of the door creating a parallel effect. A fantastic and versatile style that goes well with numerous furniture combinations.
