Comp Door Harlington Composite Door In White

Please note: The lower the U value the better, as this means the door is more energy efficient and will retain heat inside the home better. All doors meet current 2022 building regulations.

All composite doors have U values between 1.2 and 1.8. This is dependent on the exact door design and glass option specified.

The Mustang range is also dependent on design, but these doors offer impressive energy performance with U values as low as 0.92. (That's very low!)

Our doors are no different to fit to any other door hung in an outer frame, which means they require skill and care. We understand that many people like to source their own installer to save money, or even ‘have a go’ themselves if you are a handy DIYer! Please consult our installation guide before ordering, and ensure any tradesmen you have lined up are competent.

If installed correctly, our doors will require little to no maintenance. Almost all of the issues reported with entrance doors are down to improper installation, so please exercise caution!

Yes, we can offer marine-grade upgrades for customers who live within 10 miles of the coast.

Deciding which threshold and sill combination you have on your door is perhaps the most important decision. If the wrong threshold is selected, you could have issues with floor levels and the door opening clearance. There are various thresholds to choose from, and we recommend consulting the help icon on the website for a detailed explanation of each. If you are in doubt, please call or email us for advice on choosing the right threshold.

All products have measuring instructions on the product page.

Our best offering is the Mustang door, which can achieve an impressive U value as low as 0.92.

Planning permission is not typically required for replacement entrance doors, providing you are not making any alterations to the original aperture.

For refurbishment projects in a property you own, you will not need any building control or authority sign off providing you are replacing the current doors with an improved or like-for-like product.

For new builds and extensions, the products will need building regulations consent and must meet the current recommended minimum requirements. Further accreditations such as document Q, PAS24 and Police Approved may not be essential, but check that your architect or authority has not specified this.

All door ranges are available with a range of side panels and top lights, which you can select and design on the door designers.

The entrance door is the first thing many people look at on a new home and it is often the focal point of a building - with that in mind, how do you know which door is best for you?

We recommend the first consideration is budget - aluminium are truly stunning but being a true aluminium product they are more expensive than a composite alternative. If budget permits, an aluminium door is recommended (especially to match aluminium windows). With that said, if you are installing uPVC windows then a composite door is a great choice as they have matching uPVC frames and offer massive design variety.

Once your budget is established, you should then consider the key points of each door to decide which is more suitable for your project:

Energy efficiency - all are good energy performers but Mustang has very impressive energy ratings.

Security - all doors have the same accreditations in this respect. However, a Mustang door is the thickest and heaviest door.

Looks - Mustang is a very modern-looking product, Solidor and Door-Stop offer both modern and traditional appearances.

Value for money - Door-Stop is our most competitive door and superb value for money.
