However, choosing the right door is not that easy, with all the composite door manufacturers available. Whether you are looking for composite front doors or other exterior doors, most manufacturers can cater to all your needs and preferences.

If you are based in Northern Ireland or a location without one of their trusted installers, Rockdoor can provide you with an alternative.

One of the standout features of Rockdoor’s composite doors is that they use S-Glaze technology. Meaning that the double glazing is part of the door itself, so potential intruders cannot remove it to break into your home.

Furthermore, Rockdoor is proud to announce that their doors are 35% stronger than a typical GRP (Glass Reinforced Polymer) door, making it one of the most secure doors available in the nation.

2. Endurance Doors4.5 stars.

Advantages of Composite Doors

Composite doors in the UK are, without a doubt, one of the best choices a house owner can make. However, your final decision will depend on your individual needs, so it’s important to consider how composite doors weigh up compared to other options, such as uPVC and timber doors. Below are some of the most notable advantages of composite doors:

1. Durability

If you want a door that’s going to last you a long time with minimal upkeep, a composite door is probably your best bet. Due to the way composite doors are built, the unique combinations of materials mean that they are highly resistant to abrasion and weathering. Their typical lifespan is around 35 years, and without maintenance, they can still last around 32 years.

This trumps the standard uPVC doors, which typically last around 20-25 years with little maintenance. The durability of timber doors can vary greatly depending on the type of wood used. For example, pine doors only last around 20 years, whereas mahogany doors can last 60 years or more.

It’s important to note that timber doors require more maintenance compared to both composite and uPVC doors.

2. Security

One of the most important factors to consider when purchasing external doors is the level of security. Manufacturing processes for door and lock designs are always improving, so in 2022 you can definitely feel confident in the available options to keep you and your home safe.

Composite doors are one of the best options for security due to their mix of materials. They have a polyurethane core that becomes rock-solid and is usually up to twice as thick as uPVC doors. Thus, breaking a composite door is a near-impossible battle.

Even though uPVC doors have improved over the years, their typical styrofoam core is considered to be much more flimsy compared to composite doors’ hardwood internal frame. Timber doors are also a sturdy choice, however, as mentioned above they require relatively more maintenance to sustain their level of security.

Concerning locks, there are a lot of choices available for all types of doors. In most cases, the lock is what determines whether or not burglars will be able to break into your home. Investing in a high-quality lock is thus very important, no matter which kind of door you choose.

3. Style

Composite doors are available in a wide variety of colours, with black and light green being two of the most popular shades in 2022. Another plus to composite doors is that they don’t require repainting, while this is not the case for timber doors.

As composite doors are made of multiple materials, there is even more flexibility in style with composite doors. You can find a large range of designs, from modern to more traditional styles that suit period properties.

uPVC doors also provide popular styles, such as uPVC French doors or uPVC Stable Doors; however, they are generally best suited for these more contemporary looks.

4. Value for Money

When it comes to price, you can find composite doors ranging from £550 up to £2,500. Therefore, you are likely to find something suitable for your budget. However, this also means it’s important to shop around and compare prices, as you may be missing out on a better deal. To get you started, you can fill out the form at the top of this page to get up to 4 free tailor-made quotes from UK suppliers to help you find your perfect door.

Furthermore, composite doors are typically more budget-friendly than timber doors, both in regards to the initial price and the required upkeep. uPVC doors, on the other hand, are always cheaper than composite doors.

However, composite doors are more energy efficient than uPVC, meaning that you will save on energy in the long run. Chances of replacing your front door sooner are also higher if you choose uPVC. To conclude, while uPVC doors are cheaper, composite doors can be seen as more of an investment as they last longer and are more energy-efficient.

Now that you know what to consider when choosing the best composite door for you, you can take the next step in your comparison journey by receiving quotes free of charge from suppliers in your area. Just click the button below.

Opt for Energy Efficient Windows too

When it comes to windows, sash windows are a very popular style among UK homes.
