What are the common problems with composite doors?

Composite doors offer many advantages over wholly UPVC or timber doors. Each of those materials has its own set of drawbacks, by combining them into a composite door we can provide the best of both worlds in terms of security and durability. With that being said, in rare cases some issues can affect composite doors - although these can all typically be avoided by ensuring the door is properly sized, fitted and used properly.

What is the difference between a composite door and a uPVC door?

The key difference between a composite door and a uPVC door lies in their materials and construction. Whereas uPVC doors are made entirely of plastic, composite doors are composed of a number of different materials with the intention of making them stronger and hard-wearing. For example, the Rockdoor composite doors that we fit are composed of GRP (glass reinforced plastic) in addition to rigid uPVC profiles and reinforced aluminium frame boxes. This combines to create a door that is incredibly secure and thermally efficient.

Do these safety doors warp in the sun?

Only low-quality composite doors will warp in the sun, which is why it’s important to invest in a quality brand and product when purchasing your new doors. We’ve chosen Rockdoor as our supplier of composite doors, as they’re one of the few companies that meet our rigorous standards for quality. Their doors utilise an aluminium subframe which combats warping from excessive heat.

Do composite doors crack?

High-quality composite doors, such as the products provided by Rockdoor, do not crack. Rockdoor has spent years researching and developing a composite door that effectively mitigates the effects of heat to prevent any kind of cracking.

Do composite doors fade?

Composite doors do not fade over time. This is one of their clear advantages over the more traditional door materials such as wood or uPVC. Rockdoor’s construction process includes vacuum forming a high impact skin onto an intricate aluminium mould. This low maintenance grained skin makes the colour much hardier than any other door finish.

Are these safety doors draughty?

The composite doors we fit from Rockdoor are noted for their thermal efficiency - so they’re not draughty at all. All composite doors we fit combine a thermally efficient PVC-U skin with a 50mm thick sash and foam insulation to achieve industry leading thermal performance ratings. These doors also use S-Glaze to further prevent draughts.

Are composite doors resistant to scratches?

Our composite doors are made with a scratch resistant GRP material that is highly durable. As such you’ll find that all the composite doors that we fit will stand the test of time and remain an appealing feature of your home for a long time to come.

Do composite front doors expand in summer?

All doors, regardless of the materials, will expand to a greater or lesser degree during the heat of the summer. The issue is really how much this happens, and how this impacts the door fitting. We chose Rockdoor as our composite door supplier, as they have put extensive research into their products. They offer a ‘no-bow guarantee’ on all their doors, so you can buy with confidence knowing that your door will remain properly in place, no matter how hot it gets.

Are composite doors worth it?

Composite doors are more expensive than most uPVC and wooden doors, which naturally raises the question of if they’re actually worth the investment. The best composite doors offer class-leading high security, thermal performance and durability that other types of doors simply can’t compete with.

How long do composite doors last?

Composite doors have a typical lifespan of at least 30 years. Depending on the weather conditions and how well you look after it, yours could well last longer on this.

What materials are composite doors made of?

The Rockdoor composite doors we fit are made with the following: First a high impact skin is formed onto an aluminium mould. The inner frame is made using rigid uPVC profiles with an aluminium reinforced box section. S-Glaze glass is used to fit any windows that you require, providing excellent security. The door is then injected with Polyurethane Foam to ensure that any gaps are filled. The door is cut down to size using CNC technology before multipoint hook looks are fitted for maximum security.

How much do composite doors cost?

The cost of your composite door depends entirely on your project. Since there are numerous colours, styles, features and sizes to choose from we can only suggest an average of £1,800 per door. You must also account for professional installation.

Do composite doors require maintenance?

One of the best features of a composite door is that they don’t require much maintenance when compared to their wooden counterparts. One of the ways that you can extend the life of your door is by giving it a gentle clean once a month. This can be as simple as wiping it down with warm, soapy water and a soft cloth.

Can you paint a composite door?

You can paint a composite door if you wish, however this won’t be a necessary part of maintaining it. Remember that one of the key benefits of buying a door like this is its low maintenance requirements. If you wish to paint your door, then you must first clean it and sand it, before painting and then finishing with a proactive layer such as beeswax.

How strong are composite doors?

The Rockdoor composite doors that we fit provide industry-leading security that comes with a variety of features intended to make your front door impenetrable to intruders. S-Glaze technology, reinforced inner frames and nickel coated solid brass hook locks make these doors impossible to be forced open without industrial-strength tools.

Can you fit a composite door yourself?

We do not recommend that you attempt to fit a composite door yourself. Whilst it’s possible to do so, it wouldn’t be prudent to spend hundreds of pounds on a door to then risk compromising the security of that door by installing it yourself. Only by getting a professional to measure up and fit your composite door can you guarantee that it provides the outstanding security that you’ve paid for.
