Solidor Composite Doors

Solidor composite doors have a 48mm solid timber core that offers superior strength and fantastic levels of security. You can see an extensive range of these highly secure, timber core, composite doors in our newly refurbished Cardiff showroom.

The timber core is completely encapsulated in a highly durable plastic edge banding and two thermoplastic door skins. This gives your customers the look of a real timber door, without the hassle of maintenance.

Solid Timber Core

All of our composite Solidor doors are based on a proven 48mm design. This is 10% thicker than Solidors nearest competitors and offers increased protection. The added thickness of a Solidor door because it is manufactured from a solid timber core, which helps make it the most durable composite door on the market. Composite doors can initially look the same but cheaper doors are often filled with foam, offering very little resistance to intruders.

Solidor Security Just Got Even Better

Multi-point hook bolt locking and the highly secure Ultion Sold Secure Diamond cylinder ensure top security and peace of mind for homeowners. A Secured by Design upgrade is available too. When an Ultion lock is attacked, a hidden lock automatically engages, so that even if the main lock is snapped, nothing gets past it.

Lockdown mode keeps a permanent lock on your home. Nothing beats the Ultion lock for security including the finest 3-star locks. For style and security, nothing beats Solidor doors.

Side Panels for Your Front Door

If you have a space for your door that is wider or taller than needed, you have further choices to make.

Will you design the door in the middle with panels on both sides, or choose to have the door to one side and a single panel?

The space you have behind the door and which way the door opens may influence your choice.

Fantastic Door Styles

All of our stunning composite Solidor door designs can be produced as the single door that you would normally expect. What surprises customers though, is how good these doors look when styled as a French door set. Most customers think that they have to fill a large space with a door in the middle and the glass panels outside but ask your designer to show you how the space would look as French doors. We may surprise you.

You can also choose to have a Solidor door as a stable door. Some of our customers have found this useful when they have limited opening windows and want the additional airflow. This can also be a useful way to keep young children and dogs safe, allowing you to open the top part to take packages or talk to unexpected callers.

There’s also the option to include matching side panels with your chosen Solidor door.

Welsh sprinter Colin Jackson chose Heath Windows Ltd for his front door installers. He chose a stylish black Solidor to compliment his home, a perfect choice if you ask us! ​
