Cardiff and Vale Composite Doors
COMPOSITE DOORS
Secure. Stylish. Solid. And built to last.
​
When it comes to choosing a front or back door for your home, composite doors are in a league of their own — and at Cardiff and Vale Glazing, we proudly supply and install the strongest and most secure composite doors on the UK market:
Endurance Doors
Unlike traditional uPVC doors, which are often foam-filled and prone to warping over time, composite doors are built using a layered construction that offers superior strength, insulation, and security. But not all composite doors are created equal..
Why Choose an Endurance Composite Door?
We’ve fitted thousands of doors across South Wales — and nothing comes close to Endurance for build quality, style, and peace of mind.
​
Here’s why we recommend them every time:
​
-
48mm Solid Timber Core
Not foam, not hollow – just 17 engineered timber laminations making up a rock-solid core. That’s what gives Endurance Doors their unmatched strength and weight.
-
Incredible Security
Every door comes with multi-point locking as standard, and we upgrade your cylinder to the 3-star ABS Master Lock with Anti-Snap, Anti-Bump, Anti-Pick and Anti-Drill protection — complete with a £2,000 break-in guarantee.
-
Custom Made in the UK
Designed, built and tested right here in Britain — with over 80 styles and 19 colours to choose from.
-
Built to Last
Endurance Doors aren’t just secure — they’re thermally efficient, low maintenance, and backed by a 10-year guarantee for long-term peace of mind.
-
Fully Reinforced Frames
All frames we supply are reinforced, unlike many other installers who fit cheaper, unreinforced frames to keep costs down. We don’t do cut corners.
A Style to Suit Every Home
From ultra-modern designs to traditional cottage-style charm, there’s an Endurance door for every property. And thanks to the wide range of colours, glazing options, hardware finishes and side panel styles, your new door can be as bold or as subtle as you like.

Endurance Doors offer a massive range of door designs and colours and boast some amazing designs, suited to properties of both age and youth, in all settings. They are premium doors, leading the solid core composite door market and are sledge hammer proof. No paint is used on these doors or their frames, so the colour door skin and frame is guaranteed for 10 years not to fade. Many doors are painted, which often sees them fade after just 2 or 3 years.
