An Extreme Solid Core door has way more durability than most door products, giving you optimal security at home.

No composite door has sixteen layers of laminated timber and a 48mm solid core, expect for our fantastic Extreme Solid Core doors. These layers make an Extreme Solid Core unbelievably tough and strong, drastically minimising the threat posed by thieves. Made to modern standards, the Extreme Solid Core door is as good as it gets and has so many unique features.

As standard, a Solid Core door comes with an ‘Auto-Engage’ locking system, meaning that the lock will engage when the door is closed, giving you super-strong compression, a draught-free house and superb protection. It would be remiss of us not to mention the stylish of our Extreme Solid Core doors too, as they have so much designer appeal.

Unless you have a fully solid door, the glass always has a strong visual impact on the overall design, and the glazing in an Extreme Solid Core Door is no different. We have a fantastic selection of glazing at Speedy Home Improvements, which are all specifically made for this exciting door collection.

It’s all well and good that an Extreme Solid Core Door has exquisite looks, but what you want most is for it to keep your home well protected.

If you want proof of how secure an Extreme Solid Core Door is, we can inform you that it has received the Secured by Design accreditation, issued by the Police. This initiative was established to ‘design out crime’ and it’s one of only a very elite group of replacement doors to have been endorsed by the scheme.

Furnishing a Solid Core door is a fun process…

You can’t fail to be impressed by the amount of detail that there is in our very exquisite collection of handles. The handle will be one of the highlights of the design.

We have created a suite of handles that are specifically made for the Extreme Solid Core Door.

The hardware is carefully tailored for the design...

The Extreme Solid Core Door demands its own suite of hardware. Every single piece of hardware that we have developed for the range has been laboured over and is created to enhance the design and make it functional. It’s such an adaptable collection of hardware that you can easily pair any of the handles with our urn-style door knocker or aesthetically pleasing letterplate.

No door range quite compares to our Extreme Solid Core Doors. We make this claim based on several factors, including how much the brilliance of the silver slam-shut hardware aids the design. If you want an Extreme Solid Core Door with a contemporary effect, you would be best off adding our bow and bar handle configurations.
