Composite doors for commercial buildings

When choosing the best doors for any commercial building, offices, and the other working locations, it is essential to give consideration to composite doors and the serious advantages they offer. But what exactly are the benefits of composite doors for commercial buildings? In this article, we will lay out the advantages we have experienced in many years of working with these doors and also discuss any options available and when to choose them. But first, let's get a better idea of the products we're going to be talking about:

What is a composite door?How are composite doors constructed?

Composite doors are constructed from a clever combination of many different materials, each of which provides an integral part of the overall stability, strength, and appearance of the door. Those layers include:

They are glued together under extreme pressure and this serves to ramp their stength up even further. The high-tech process and materials, when finished, results in a remarkable product indeed, as well will discover. 

Benefits of composite doors

The list of benefits of composite doors is an impressive one that includes:

Superior insulating performance

The materials used and the layered composition of composite doors make them exceptionally efficient at preventing temperature transfer from one side of the door to the other. This works whether it is sweltering outside and you want to keep the air-conditioned air inside, or there is snow and ice on the ground outside and you want to stay warm and toasty inside. Commercial buildings are already expensive to heat or cool and keep that way, so doors that are unmatched in their insulating properties are perfect choice.

Environmental responsibility

Many companies are concerned with doing their part and reducing their environmental impact wherever possible. Lowering energy bills is a superb way to start and eliminating energy-sapping temperature changes is one of the huge benefits of composite doors for commercial buildings. Not only do these last for decades, reducing the need for extra materials to be produces but they can also be largely recycled or repurposed at the end of their working lives.

Streng and durability

One of the most impressive, useful benefits of composite doors is that they are so incredibly strong and durable. Composite doors can be expected to last for many decades and look just as good as they did when brand new. They do not mark easily and, as we will see when discussing security shortly, are virtually indestructible.

Weather resistance

Unlike traditional wooden doors, composite doors are perfectly adaptable to any weather conditions, no matter how extreme or prolonged. They have weathertight seals that keep the elements at bay and simply will not warp, bow, or twist. When the elements attack, they are almost unbelievably hardy and not suspectible to:

High Security

Composite doors are high-tech, impact-resistant addition to any modern security system and are hugely popular in residential and commercial buildings alike for this season. Add to this inclusion of multi-point locking systems. installed at potentially exploitable weak spots across the frame and you have a door that is all but impenetrable. The locks are designed to be impervious to drilling or picking and have a cylinder that will not snap. When combined with reinforced, high-density cores and steel frames, the security level is off the chart and far exceeds many recommended standards.

If your commercial buildings is left unattended outside of working hours then it is inconceivable you would consider any other kind of door to protect your business. If you want to go all out the make it more likely that the wall will fall down before the door gives way then can you can select additional latches and bolts as optional extras.

Customisable design options

Unlike traditional doors, composites are extremely versatile in terms of their appearance. From the range of non-fading colours to finishes that give the appearance of wood and others materials, the options for customisation are impressively varied. This is especially helpful if your commercial building needs to match an existing colour scheme or company branding style. If you prefer larger glazed panels then those are option to consider, as are any engraving and artwork you may wish to adorn them with. The final touches include a range of hardware options from letter plates and door-knockers to handles and trims.


One of the best benefits of composite doors is that they don't require frequent maintenance to remain in premium condition. They don't ever need to be repainted to look good and all that's necessary is the occasional wipe-down with a damp cloth.

Sound insulation

No matter the location of your commercial property, or the nature of the activities therein, you are unlikely to be disturbed by outside noise or to disturb others with your own. The materials that provide all the strength and insulation also happen to keep lots of noise out and give you maximum privacy and optimum working conditions at all times.

Final thoughts

It barely needs to be reiterated how vastly the benefits of composite doors outweigh the disadvantages, the only real one of which is the increased cost. Even this is likely to be negated over time as energy and insurance bills are reduced. Composite doors are simply unrivalled in any department and will genuinely stand the test of time.

The ability to design and install bespoke composite doors that will last for decades and take up no more of your precious time or money is not to be underestimated. They will continue to represent your company beautifully and provide the kind of streng and security all commercial buildings can benefit from.

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!

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!
