Doors FAQs

Question 1

What does GRP mean in doors?

Answer

GRP stands for 'glass reinforced plastic'. It can also be known as fibreglass. GRP is used as a skin for composite doors, adding a thick layer on each side of the door. Thanks to this, GRP-based doors are one of the best options for external doors due to their durability and strength.

Question 2

Which is better, composite or uPVC?

Answer

There is not necessarily one objective answer, since both have different benefits from each other, as well as those that are similar.

Security - composite doors are known to be one of the strongest types of doors available, thanks to their thick cores and range of security features. Composite doors are often up to twice as thick as uPVC doors. The security options for uPVC doors are still prevalent, though. Modern options typically have features such as multi-point locking systems and reinforced panels.

Value for money - value for money is one of the main benefits for uPVC doors. They are supremely cost-effective while still laying claim to a host of other benefits. Composite doors are more expensive, but their modern designs, thermal efficiency and security credentials mean that there is still certainly value to be had.

Energy efficiency - composite doors are engineered to achieve fantastic levels of thermal efficiency, thanks in chief to their contemporary designs. UPVC doors are also effective at keeping homes warm and are able to achieve some impressively low U-values. The multi-chambered profiles act as thermal barriers to help retain heat.

Question 3

How long will a UPVC door last?

Answer

UPVC doors are typically known to last around 20-25 years with the potential to last longer. As always, any such figures will be based around the homeowner keeping up the maintenance effectively. Fortunately, uPVC doors are very low maintenance and generally only need a wipe down with some warm water and a cloth. The aesthetic appeal can be easily maintained with regular upkeep.

Question 4

What are the benefits of a composite door?

Answer

Composite doors are one of the most popular options for good reason. Their market-leading designs provide excellent security options thanks in large part to their thick, durable GRP skins. The Solidor range, for example, has a broad selection of additional security features and accessories, as well as innovative locking systems. The customisation options are also plentiful, meaning you can design your door to your exact desires. Given you can design your dream door, it is a good thing that their durability provides a long lifespan, often up to 35 years.

Question 5

Which door material has the longest lifespan?

Answer

Aluminium - Naturally, aluminium is one of the strongest and most durable materials available. It is not a surprise, then, that it has potential for a very long life. Its life expectancy can be up to 45 years.

Composite - The estimated life expectancy for composite doors is up to 35 years. There is even potential to last longer, but for one of the premium materials available, there is a lot of life available.

uPVC - UPVC doors can also have the potential to last up to 35 years or more, but the closer estimate is between 20 and 25 years.

Timber - Timber is known to be the longest-lasting of all door materials. However, that is largely dependent on the level of maintenance, with timber also being the hardest material to maintain. Timber doors can have the potential to last well over 50 years, given they receive the correct care and maintenance. Interior wooden doors are likely to last even longer than exterior doors.

Question 6

Do you need planning permission and building regulations for a door?

Answer

Usually, you will not need planning permission for a door. If you are planning to install a new door, then as long as it is similar in appearance to the one that you are replacing then planning permission will not be required. Minor additions or repainting are also things that do not need planning permission and fall under permitted development rights instead. Installing doors such as French doors, bifold doors or sliding doors also fall under permitted development rights. You will, however, typically need approval from buidling regulations. Other restrictions include:

Listed buildings

Article 4 Direction

Designated areas (i.e. conservation areas, national parks, areas of outstanding beauty)

Leaseholders

Question 7

What are the best back door options?

Answer

French doors - French doors are one of the most aesthetic doors available, steeped in architectural history and heritage. Their design lends itself to traditional properties but they are still a fantastic option for modern homes. French doors are able to open both inwards and outwards and in turn provide an influx of natural light and fresh air.

Stable doors - Stable doors provide fantastic amounts of versatility for any home. Due to their unique design, stable doors have a range of benefits. For example, you can couple added ventilation and natural light intake with added safety due to the split design; you can keep the bottom half closed to protect children and pets, while keeping the top half open for light and fresh air.

Bifold doors - In a similar vein to French doors, bifold doors are able to open up a room and give great views of your garden and beyond. Bifolds have proven to be a very popular choice in recent times and they are an ideal option for contemporary homes, particularly the strong yet sleek aluminium variant.

Patio doors - The views and natural light intake are amplified with patio doors. Due to their design, which features a large quantity of glass fitted from the top to the bottom, you are able to benefit from floods of light. Again, the aluminium option is popular because it can make the frames even slimmer, allowing for an almost uninterrupted view.
