Our Solid Core Composite Doors lead the way when it comes to both style and security.

Constructed from a laminated veneered timber called Kerto®, sixteen layers are used to provide strength and durability. In many doors, grain direction can be a weak spot with timber warping or even splitting. Our construction ensures the woodgrain is running in different directions, thereby removing any potential weaknesses.

The Benefits of a Solid Core Composite Door

GRP Doors

Composite doors are typically made from a material called Glass Reinforced Plastic (GRP). A door will be comprised of two outer layers of GRP which are attached to either side of the doors sub-frame. The gap between the GRP layers is then filled with high density foam. Only a small proportion of the finished door is manufactured from a solid material. The GRP layers are robust but can be susceptible to scratching and denting, neither of which are easy to repair. You may also find that some GRP door skins fade over time, especially those in direct sunlight.

Solid Core Composite Doors

As we’ve detailed above our Solid Core doors are created using 16 layers of Kerto®, a laminated veneered timber that is incredibly strong and dimensionally stable. Kerto® is used in a wide range of construction projects from new builds to renovation and repair projects.

The 16 layers of Kerto® are orientated so the wood grain is running in multiple directions. This increases the strength and rigidity of the finished door and also offers significantly improved security.

Bonded to the Kerto® layers are two PVCu skins. PVCu is far more durable than GRP and is less prone to fading or scratching. The PVCu can be created with a highly realistic woodgrain effect or in a smooth finish. Both options are available in 24 colour variations.

Key Features

Choice of Frames

The solid core composite doors come complete with a sculptured frame with Chamfered available on request.

Threshold Options

The standard threshold is a 77mm PVCu with the option of a 57mm low threshold if required. We can also create a 24mm aluminium threshold which can be used in conjunction with a wheelchair ramp.

Sustainable Timber

We are passionate about the environment, and we appreciate the impact that manufacturing can have. We are very proud of the fact that all the timber we use is sourced from sustainably managed forests. What’s more, at the end of the doors life the wood can be recycled rather than being sent to landfill sites.

Picking a Colour

Perhaps the hardest part of choosing one of our solid core composite doors is picking the colour. Our range has 22 colour options, plus white and cream.

Fit and Forget

None of our doors require painting or any other maintenance. We recommend they are cleaned to keep them looking their best, and this can be done in conjunction with having your windows cleaned.

Corona Virus Update

Since the Government announcement regarding the Corona Virus on Monday 23rd March, Just Doors and Conservatories have worked within the Government safe working guidelines to fulfil orders. This has become increasingly difficult in light of suppliers and customers ceasing trading and self-isolating and the trend would suggest that this is set to continue.

We have therefore taken the difficult decision to ‘pause ‘manufacturing and deliveries from Friday 27th March at 4:30 pm.

This will be reviewed in line with the rest of the UK on the 14th April with a view to commencing production.

This is a decision we have been preparing for and we trust that you will understand our situation.

Quotations & Orders

We still have people working from home and as such, we are still able to process quotations and orders, we are, however, not in a position at this time to confirm when those orders will be completed.

Please request your quotations and place your orders by email to:



Finally, we wish you, your colleagues and family good luck during this difficult period and we look forward to working with you again when our lives return to normality.

Good Luck, best wishes and stay safe.
