Why composite doors resist weather and age better than traditional doors

There are several very good reasons why composite doors are better than other styles in almost every way and have become more and more desirable over the years. They are inherently so much more weather-resistant and age-proof than other, more traditional doors and this essentially comes down to the bespoke materials used to create them and the scientific way that they are combined and utilised. 

How are composite doors constructed?

Composite doors are constructed using a mixture of natural and synthetic materials. They are carefully combined and balanced in a way that ensures maximum strength and durability. One key step that elevates the robust nature of composite doors to an entirely different level is that the layering and glueing together of the materials are done under extreme pressure. This creates a tight bond that is unlike anything found in any old-fashioned door. The materials used often include:

  • Wood 

A timber core provides the strength and durability that the other layers build upon.

  • uPVC (unplasticised polyvinyl chloride)

A strong, lightweight, and low-maintenance plastic building material.

  • Metal

The frame that surrounds the door once the layers have been sealed together tends to be metallic for strength and added security.

  • Glass

Small windows allow light to pass but remain good at preventing temperature transfer and tend to be too small to be useful attack points for intruders.

  • Foam

The foam layer traps huge amounts of air inside the material and is exceptional at preventing the transfer of heat or cold.

  • GRP (glass-reinforced plastic)

Another key element in the prevention of temperature loss and also an incredibly strong one. GRP is flexible but almost freakishly strong and virtually impenetrable. In fact, it is not dissimilar from bulletproof glass in the way that it is constructed. 

An all-weather solution 

The weather-resistant, anti-ageing qualities of composite doors are a direct result of the materials used to construct them and the cutting-edge method by which they are layered together and sealed. This makes them strong and durable and helps to keep the heat in or out, depending on your needs and the climate in which they are installed. Wooden doors are, of course, made of natural material that is much more susceptible to weathering and they require regular painting or staining to protect them from the elements. 

What are some other reasons why composite doors are better than other styles?

When it comes to high-quality composite doors, there are a huge number of benefits and almost no disadvantages. Even the added cost is mitigated by the energy that is saved by preventing almost all heat/cold exchanges. 

  • Strength and security

Composite doors are significantly stronger and hardier than traditional wooden ones. Even a solid wooden door will eventually yield to forced entry given enough time and effort but a composite one is so difficult to damage that it might almost be considered impenetrable. The Rockdoor composite doors that we offer here at Rock Solid Doors represent the ultimate in security with superior features like:

  • Winkhaus multipoint locking system 

  • High-impact skin 

  • Box section reinforcement 

  • 50mm core 

  • A to A++ energy-rated glass 

  • 3 Star Euro cylinder as standard

  • Maintenance

Composite doors require almost zero maintenance as they are infused with materials that easily resist stains, water damage, and general wear and tear. Whereas a traditional wooden door will require regular coats of protective varnish and other attention, the most a composite door requires is a quick wipe-down with a damp cloth every now and again. And even that is purely for cosmetic purposes more than anything else. Composite doors are exceptionally tough and impervious to almost anything that the world can throw at them.

  • Reduced energy costs

Composite doors are so good at insulating interiors that it is not uncommon to notice significant bill reductions almost immediately once they are installed. 

How long do composite doors last when compared to wooden ones?

Although properly maintained wooden doors can actually last for many decades, they do not fare well at all without that regular care and attention. Harsh outdoor environments soon take their toll on wood in the form of potential rot, parasites, and warping due to heat and moisture. 

Composite doors are generally made to last for a maximum of around 30 years but are much more resistant to changes in climate, attacks from insects, and decay. They fare superbly well in extreme conditions and this is why composite doors are better than other styles when it comes to their suitability for use as external barriers.

Extremely happy

I was extremely happy with this from start to finish. My flat is in an awkward location, but Paul visited promptly and provided expert and comprehensive advice. Ordering was error-free and installation took place on the day specified. As well as doing a very neat job with a high-quality door, the installers were able to modify the installation as they went when snags were identified (e.g. a very narrow hallway meaning a safety chain couldn't be attached so a spyhole was fitted instead - from stock carried on the van). It was a joy to work with people so straightforward to deal with and skilled at their work. I am already recommending you to visitors who comment on the door - thank you

100% recommend Paul and Harry a great father and son team! I'm so pleased that we used them to supply and fit our new front door. Straightforward to deal with from start to finish and communication throughout was excellent. They are extremely knowledgeable and were able to offer advice and suggestions when we were choosing the door we wanted. Nothing was rushed during the installation with great attention to detail. They took away our old door and frame and left everything clean and tidy at the end of the job. Thank you, Harry, for taking the time to go through everything with us at the end of the job, much appreciated. I would not hesitate in using Paul and Harry again. Thank you both so much, we are so pleased!

Had a door fitted by these very friendly chaps about 18 months ago. We're very happy with it. When an issue arose with the mechanism, they came out and fixed it in about 5 minutes and it's as it if is brand new again. Very pleased, would highly recommend.

Highly recommend. We had our front door fitted by this lovely team. They were friendly, helpful, willing to listen to me debate options and provided helpful advice for choosing the right door for us. When he had a slight issue (no fault of their own) they came out to us the very next day and sorted it. Such a good supplier to work with!

Brilliant service. No hidden costs or fees and no heavy sales tactics. Very open and clear from the start, and they worked really hard to fit a great new door in our thinner than average doorway! Great value and great result. Will be recommending to all.

Highly recommend Rock Solid doors. We have used this friendly family company several times and have recommended them to others who have been equally impressed with the high standard of work and the product. We have received quick service and found them to be very reliable knowledgeable with no hard sell. The installations have been carried out professionally and they go the extra mile to ensure you are happy with everything. The external doors are robust and we are impressed with the quality of the product.

Faultless customer service from a fantastic company to do business with. From start to finish it’s been a pleasure buying composite doors from Rock Solid Doors – in fact, we were so impressed with the front door and installation service they provided (we opted for a Solidor Ludlow 2 with 2 x fully glazed side lights) that we got them back to supply our utility door (Windsor Solidor – fully glazed) shortly afterwards. Paul dealt with our initial queries promptly, came to measure on site and provided a competitive quote very efficiently. These guys are first-rate craftsmen and know their stuff: evidenced by working around a couple of quirky construction issues without any problem – leaving us really impressed with the end product. It’s great to come across a local business that takes pride in what they do, going the extra mile for customer satisfaction – we cannot recommend Rock Solid Doors highly enough! Thank you Paul and Harry!

Brilliant service from Paul at Rock Solid; our letter box seal had gone causing a slight leak - he responded immediately, attended this week and fixed with a new gasket. Would highly recommend the product and the service.

I ordered my Vogue Rock door with the Ocean glass from Rock Solid Doors at the end of 2021. I had a number of criteria when searching for my new entrance door. It’s ability to insulate had to be A rated. I also wanted it to have a good quality locking mechanism that is smooth in action. My new door needed to be modern with a pane that lets plenty of light in and thus goes lower than the half line on the door, while leaving sufficient height for the letter box, so it is sufficiently high to be comfortably reached by our postman. The Vogue Rock door provided all that and more. I love sailing and the Ocean glass design evokes the lines of a sail in a beautifully minimalistic fashion. It also makes the door look unique, which is always a bonus. During my search for the perfect door I had lots of technical questions too. Only Paul and his colleague from Rock Solid Doors were able to answer all my questions and provide a door that offered what I was looking for. They supplied and fitted my new door in early 2022. My heating bill has gone down noticeably, as a result. With the golden oak wood grain on the outside, my door looks beautiful and elegant. Everyone who comes to the house for the first-time comment on it. The multi-locking mechanism has a smooth action and it is easy to use. The white wood grain on the inside finishes off the hallway like a designer window and door in one. Paul and his colleague went out of their way to make sure that I have the door and the finish just, as I wanted and that it worked seamlessly there on. We could not be happier. Thank You!
