How composite doors can with help noise reduction

The list of benefits that comes to mind when considering the installation of high-quality composite doors is a long and impressive one whichever way you look at it. We tend to focus on their:

  • Incredible strength
  • Thermal efficiency and subsequent energy-saving
  • Increased security
  • Durability
  • Zero maintenance
  • Wide range of finishes and options for customisation
  • Longevity
  • Stylish good looks

In the face of so many impressive, practical properties, the question ‘Can composite doors help with soundproofing?’ is seldom asked. Yet one of the lesser-mentioned major advantages of composite doors is that they possess inherent noise-reducing qualities. Some might view this as nothing more than an added bonus, others as a highly-desirable feature. Either way, it is another tangible reason why composite doors are light-years ahead of other options in virtually every conceivable way.

Can composite doors help with soundproofing?

In a word - yes. One of the many benefits of composite doors is that the dense, tightly-packed layers of insulating material act as a superb barrier to excessive noise in either direction. Composite doors are not intentionally designed to be soundproof, it is the nature of their construction that provides this effect as a bonus to the other incredible benefits they offer.

Why do composite doors help reduce noise?

The multiple layers of materials used in the construction of composite doors are key to their soundproofing qualities. But what exactly are those layers made from and what is their intended purpose? The layers inside composite doors usually include:

  • Solid timber or laminated hardwood core
  • uPVC
  • Insulating polyurethane (PU) foam
  • GRP (Glass Reinforced Plastic or fibreglass)
  • Strong metal frame
  • Double-glazed glass

The incredible strength and durability that these layers provide come not just from the nature of the materials themselves, but also from the way in which they are constructed and joined together. The layers are glued under extreme pressure, making them extremely dense and enhancing their soundproofing qualities exponentially. Even though the layers are tightly compressed, a typical composite door has a thickness of around 44mm and is comparatively thicker than a traditional wooden or hollow front door. The sheer density of all that material compressed into a tight space gives the doors incredible strength and also keeps out a lot of unwanted noise.

A snug fit is key

Because composite doors are manufactured under carefully controlled conditions, their tolerances and clearances can be strictly monitored and adjusted. These stunning doors are essentially part of a set that also includes the surrounding frame, where a great deal of the strength lies. The fit and finish of these two elements are so perfectly in sync because the pieces are designed and constructed to go together.

Unwanted spaces and gaps that plague lesser doors, allowing draughts of air and unwanted noise to pass are eliminated with composite doors. When we take this tight fit and add double, and occasionally triple-glazed panes of glass, it is not hard to see why composite doors are so effective at soundproofing.

When is soundproofing useful?

Most of us have experienced the misery of noisy neighbours, bustling businesses and roadside locations disturbing our tranquillity at one time or another. If the property in question is situated close to an airport flight path, by a road, or any other loud entity, composite doors are a superb way to help counter that disturbance. The effect works both ways and maximising soundproofing helps in situations where the inhabitants intend to make a lot of excessive noise and don’t want to upset the neighbours. So, how much can composite doors help with soundproofing? By themselves, composite doors are not capable of completely removing nuisance noise but have been shown to reduce sound by up to 36 decibels. When combined with the strategic use of double-glazing and other sound-muffling materials, they form part of a very effective soundproofing strategy.

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.

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!
