Solid To The Core Composite Doors

Endurance composite doors are renowned for their strength and security, our 48mm thick cross-bonded veneered laminated solid timber core delivers unrivalled strength and dimensional stability and is a natural choice for high security, providing our homeowners peace of mind.

Endurance doors are made up of 17 laminations making the door nearly 10% thicker than most composite doors. By investing in our doors, you’ll be able to enjoy an unrivalled degree of security and performance. You won’t find an entrance door tougher, safer or more reliable than our solid core composite door.

Outclassing The Rest

Many composite doors on the market utilise a traditional ‘stile and rail’ internal subframe, which offers inferior performance when compared to the Endurance solid LVL core. This is important to note when you’re looking for a new door for your home.

Stile and rail sub-frames are usually filled with either a PU foam core, or a mix-species timber core. This notably reduces the inherent strength of the door, and can even result in some doors bowing due to the lack of structural integrity.

With the Endurance design, you can be sure that security and strength are never affected by a poorly designed sub-frame. We know that feeling safe in your home is a priority for you, which is why we make it a priority for us. Our solid core doors can’t be beaten.

What Makes the Timber Core Design Different?

Built to Last

Endurance is not just in our name. Due to the inherent thickness of our composite doors, they can offer a much higher lifespan than conventional composite door designs. Outdated designs can often warp out of shape over time, effecting door performance and appearance.

As our timber core comprises laminated layers, you will not have to worry about this happening in your home. This core is further enhanced with our unique Moisture Barrier System, which works to protect your door against water damage and delamination.

Sledgehammer Tested

To ensure all Endurance doors operate to modern standards, we test them in accordance with common burglary techniques. We have even put our doors through a sledgehammer testing process, showing how difficult it would be to create in a hole in the door that you choose.
