The term ‘composite door’ is well heard of within the industry. However, do we really know what this means and how they can improve your home? No two composite doors are the same across the industry, with different colours, finishes and cores. So, we have created a comparison between Endurance composite doors and other leading composite door brands, including Solidor, to help you find the perfect door for your needs.

What Is A Composite Door?

What is a composite door? A composite door is made up of a variety of materials, which can include uPVC, wood, insulating foam and glass reinforced plastic. When combining these materials together effectively, a strong and highly secure composite door is created. However, the wrong combination of material or low quality materials will create an inferior door. Composite doors vary across the industry, and no two composite doors are the same.

Endurance Composite Door

The Endurance composite door has a solid timber core that is made up of 17 crossed laminated layers of veneer lumber, making it the strongest and most durable composite door on the market. A unique moisture barrier strip is also enclosed in the bottom of the door, stopping water ingress that can lead other composite doors to swell or warp.

Finally, the tough skin that is used to give an Endurance Door its authentic timber-like appearance has been specifically designed to reflect up to 95% of the heat from the sun. So the coloured skin of an Endurance door won’t fade or crack no matter how hot the British summertime gets.

Solidor Composite Door

A Solidor composite door also has a solid hardwood timber core, which sets it apart from softwood timber cores in the industry. While it does have slightly fewer layers of timber than the Endurance door, it is still a powerful door in the market, offering homeowners both security and durability. Solidor has a less robust barrier strip at the bottom of the door, which can make it more susceptible to both bowing and warping.

This said, Solidor composite doors have been firmly established in the industry. Solidor has an average rating of 3 stars on their Trustpilot page, sitting on the 55% mark for excellent reviews. Like all companies, there will be a range of excellent and poor reviews on their site.

What Other Types of Composite Doors Are There?

Not all composite doors are made equal. Under the term ‘composite doors’ there are a variety of different products on the market. While both Endurance and Solidor are famed for their solid timber core, there are also composite door manufacturers who produce composite doors with a core made out of high-density polyurethane foam. Whilst these types of composite doors can be energy efficient, they cannot be compared with the quality and level of security offered by a solid timber core composite door.

Always check to make sure that when comparing composite door products you pay attention not only to how the door looks but also what it is made from and how it is constructed.

What is a Solid Timber Core?

what are the benefits of the solid timber core external doors

With Endurance composite doors, you get 17 cross laminated layers of Kerto veneer lumber. The Endurance door layers have been designed this way to provide the door with a level of solidity to its timber core. The solid timber core ensures our composite doors are resistant to bowing or warping. The Endurance door slab has a bowing tolerance of just 3 millimetres. This means that if your door were to bow even slightly, we would replace your door slab free of charge.

Endurance doors are one of – if not the – heaviest door on the market, making them the sturdiest and most secure composite door.

The Endurance composite door has a unique moisture barrier system that prevents moisture build-up, which helps to protect the solid timber core from bowing, warping or swelling.

Solidor Solid Timber Core

Solidor composite doors measure the same 48mm thickness as Endurance, but with only 3 layers of laminated veneer. Solidor composite door slabs have a higher bowing tolerance with 7 millimetres of bowing. However, they still offer a hardwood timber core to their doors, making them a durable product.

Other Composite Door Brands

Many other brands of composite doors provide a core that is made from soft timber or even a high density polyurethane foam. These cores can be enough to provide your home with a solid, durable door. However, with a softer core, the door is automatically more vulnerable to break-ins.

Endurance Composite Door Reviews

Here at Endurance, we have extremely positive feedback from our customers.

“Andy came out and surveyed, and took me through the many choices available from Endurance. I chose an Etna, which is a design similar to what I had, mainly because I loved my old failing door. I’m amazed at the difference in security and quality of my new door. It has a solid timber core and high security locking mechanism. The door is extremely sturdy. I’m thrilled with my door and the entire experience. The 10 year guarantee gives me complete peace of mind.”

Abbey Windows, a Reading-based installer have been long-standing Endurance customers. The managing director offered his thoughts on Endurance composite doors in his interview where he stated he would recommend other installers to join the Endurance installer partner network:

“Yes, I recently recommended Endurance on our Reading Trade Windows Facebook page. It was all because of the reasons I’ve just given. We had a gentleman, who buys about ten doors a month, who was having problems with a different solid core door manufacturer. The last 8 out of 10 doors that were delivered had a 6mm bow in the slab, which they were not addressing. I recommended the Endurance door design because its inherent strength bypasses this problem. Also, if we have had other problems, Endurance has always addressed them.  It’s fantastic to have that support.”
