Endurance Composite Doors – Premium Made-to-Measure Entrance Doors

Built for strength, security and lasting style

Welcome to the Endurance Doors collection at Window Rite — a range of premium composite doors engineered in the UK for exceptional performance and timeless design. With a solid timber core, robust security features and an extensive choice of styles and finishes, Endurance Composite Doors offer a perfect entrance solution for every home.  

Why Choose Endurance Composite Doors?

Unrivalled Strength & Security

Endurance doors are constructed around a 48 mm thick solid timber core with 15 + crossed engineered layers, making them significantly stronger than standard composite doors and highly resistant to impact and break-in attempts — many designs are even sledgehammer-tested.  

£2,000 Security Guarantee

Each door comes with a robust £2,000 security guarantee, giving you added peace of mind that your home’s entrance is protected by industry-leading locking technology.  

Made in Britain & Customised to You

Every Endurance door is made to measure — from style and sizing to glazing, hardware and finish — so your door perfectly suits your home. Choose from multiple collections and customise with colours, glazing styles and premium accessories. 

Exceptional Weather & Fade Resistance

With heat-reflective door skins and a high-performance moisture barrier system, Endurance doors stay looking great and perform reliably in all UK weather conditions, resisting cracks, warping and fading over time.
