The door’s inherent strength comes from its unique composition: 16 cross-locking layers of laminated timber combine to create the door’s robust core.

Our Solid Core Doors are the strongest and most secure composite doors you’ll find on the market. As much as the front door will invite guests in, the presence of an Extreme Solid Core Door will keep unwanted visitors out. Its 48mm core is impossible to shift and the addition of an automatically engaging lock with a ‘Snap Secure’ cylinder will keep your home, family and possessions safe. Permaframe’s Solid Core Doors include an ‘Auto-Engage’ locking system that does exactly what it says on the tin, further securing your property.

The Extreme Solid Core Door offers more than just security and aesthetics. Thanks to its 16-layered inner core, the door acts as an insulator and helps your home retain heat far more efficiently than any other type of composite door. Additionally, these doors feature three weather seals whereas most standard composite doors have just one. This puts less strain on both your boiler and your wallet, resulting in a house that’s ultimately cheaper to run.

Extreme Solid Core Door

Given that the door’s inner strength comes from its 16 individual layers, we’re pleased to offer our customers 16 bespoke door designs. These are available in 22 fantastic colours, to create a total of 352 possible combinations. No matter the style of your property or your tastes, you’ll find the perfect door to fit your home in our collection.
