An Extreme Solid Core Door takes door security to new heights and is as durable as will get anywhere.

Extreme Solid Core Doors are the only composite doors in existence that have sixteen layers of laminated timber and a 48mm solid core. Layering to this extent makes an Extreme Solid Core Door markedly stronger and more robust than every other variety of composite door being sold today. It also has features that you just won’t find in standard composite doors – that’s why it’s a market-leading design.

An ’Auto-Engage’ system is present within its design and the role of it is to automatically engage the door when it closes for super-strong compression and to see off the threat posed by thieves. There’s no sacrifice on style, which you will witness when you view our classic and contemporary designs.

The energy efficiency levels of our glazing are impressive, so they will keep your hallway warm and cosy, plus light will pass through the glass without any hindrance.

Exhibit your creative side and let your imagination run loose when you come to design your Solid Core Door. If you’re a fan of sleek designs, our aluminium offerings will be right up your street. Your advisor will also introduce you to the many cottage and classically-styled designs included in the range.

Don’t overlook the door handle…

It’s easy to get side-tracked and put too much emphasis on the colour and design when you should also focus on the handle for the door. The handle is far more than just something for opening and closing the door.

Extreme Solid Core Doors have a dedicated suite of handle solutions, and they will all finish off your design so brilliantly.

The hardware for the door is so imperative to everything…

Premier Windows has a hardware suite that features a massively eclectic and practical collection of door furniture. A matching letterplate for your Solid Core Door can really set it off and so could an urn-style door knocker. Our brushed Slam-Shut hardware will bring added security and style to the design.

A bow or bar handle is at the height of modern luxury, while the cottage-style cylinder pull is for those who are pure traditionalists. Either of the two will automatically lock once the door is closed so that you don’t have to be fearful of thieves making an unwelcome entry.
