Rockdoor vs Timber Core Composite Doors

The clear winner when choosing a new door is…

A Rockdoor… But then of course, you’d expect us to tell you that there is really no comparison between a Rockdoor and a timber-cored composite door sold by our competitors, but then we would say that wouldn’t we? So let us explain why our Rockdoors stand out from the crowd.

When we’re talking about timber-cored composite doors, we mean the timber doors with coloured skins applied to them. You may have seen them online or spoken to window and door companies who sell this style of door.

So we believe it would be beneficial to people just like you to know a little more about the differences between timber cored doors and Rockdoor, the original composite doors, that we designed, manufactured and improved upon for over 25 years.

Rockdoor is an engineered product that features levels of reinforcing and security unseen in the industry. Each door is carefully made with a 360˚ ring of an aluminium subframe, protecting the sash and contributing towards enhanced thermal performance and a stronger door.

This means that all of the locking components (the bits that ensure potential intruders force open your door), are securely fixed into strong metal at all times.

Wooden doors have no alternative but to fix through a plastic edging which can break into the timber itself, potentially causing significant problems, aside from becoming more vulnerable and weaker.

View the Rockdoor range of composite doors

The Rockdoor range of composite doors comes in 29 composite door styles, available in 13 different door colours. So no matter if you’re looking for new front doors, back doors or even double doors, French doors or stable doors. There’s a wide range of Rockdoor composite doors available to compliment the look and style of your home.

Especially unique to Rockdoor

With 29 door styles and dozens more glass designs, 13 unique door colours and countless pieces of door furniture, there is always a style unique to everyone.

Not only do a number of timber core doors follow the same styles and designs of their competitors, but they are also mostly quite basic in appearance.

Here at Rockdoor, we have styles and colours to suit a wide range of tastes, with our designs being completely exclusive to us, thanks to our skilled in-house designer creating door designs just for us! Our range of composite including front doors, back doors, double doors, French doors and stable doors are instantly recognisable thanks to their uniqueness.

For instance, take the door pictured, which is an anthracite grey Vermont composite door, you won’t find this gorgeous door anywhere else on the market, all with the added benefits of a thermally efficient PU foam core and 3* diamond secure locking cylinder – as standard, unlike in a timber door that can quite often have poor thermal efficiency and be more at risk to break-ins.

Doors guaranteed not to bow

Unfortunately, timber doors and timber core doors are the most prone to bowing in the entrance door market, as the wooden composition is extremely vulnerable to movement, especially when exposed to a variety of temperatures – even the British Summertime is enough to make a timber door expand or even shrink with how unpredictable it is!

This can result in the timber door becoming hard to lock, and with time even harder to shut. Overall, if timber gets wet, then this sets off a chain reaction of issues that will lead to the door failing, compromising your security and the warmth of your home thanks to draughts and water ingress which could literally rot your door from within.

Here at Rockdoor, we offer the peace of mind that our doors won’t bow like a timber door can, guaranteed!

Since January 2021, we have been able to offer a ‘No Bow Guarantee’ on all of our Rockdoors manufactured after this time period, something that we’re really proud of.

Our quality speaks for itself

When considering Door Set Energy Ratings (DSER), it is no wonder that Rockdoor has the largest range of A-C rated composite doors, consistently outperforming timber and timber core composite doors.

Not only does the high-density PU foam and unique S-Glaze technology allow our doors to consistently outperform our competitors, but it also keeps you and your family incredibly warm thanks to our thermal efficiency properties.
