What makes a composite door 'Xtreme'? Breaking down our performance promise

There’s no shortage of composite doors out there. Homeowners expect style, strength, and security as standard, but for installers, the real test of a product is how it performs on site and how it stands up in the years ahead. That’s where Vista’s XtremeDoor composite door range sets itself apart.

Backed by 30 years of manufacturing experience, XtremeDoor isn’t just another composite door; it’s a product built around reliability, installer confidence, and proven performance. From superior thermal efficiency to best-in-class security and unmatched durability, every detail is designed to make your job easier and your customers happier.

So, what really makes a composite exterior door ‘Xtreme’?

Thermal efficiency that works harder for your customers

Energy performance is no longer a ‘nice to have’, homeowners want reassurance that their new front door will keep bills down and draughts out, and installers need products that deliver without excuses.

Independent testing at the University of Salford showed XtremeDoor to be 19% more thermally efficient than a timber door. With U-values comfortably below the 1.4 W/m²K required to meet current UK Building Regulations, installers can fit with confidence knowing they’re offering a product that outperforms alternatives. Triple-seal frames eliminate draughts and help reduce after-sales complaints, giving you fewer headaches down the line.

Security that wins trust

When it comes to front doors, homeowners are buying peace of mind as much as appearance. A product that falls short on security creates problems for you as the installer, so we’ve built XtremeDoor to exceed the toughest standards.

Every door comes with a five-hook locking system, a major upgrade on the industry-standard two hooks. The cylinders are anti-snap, drill, pick and bump resistant, PAS 24 certified and Secured by Design approved.

To back that up, there’s a £3,000 money-back guarantee in the unlikely event of a break-in caused by product failure. It’s the reassurance that helps you close sales, and the confidence that you’re fitting doors that your customers can rely on.

Durability that reduces callbacks

Composite door prices vary, but what installers really care about is long-term performance. A cheap product that warps, fades or fails will cost you in repeat visits, wasted time and unhappy customers.

XtremeDoor uses a 4mm GRP skin, double the thickness of most doors on the market. The same material is used in yachts and wind turbines, meaning it’s built to withstand harsh conditions without flaking, cracking or discolouring.

It’s also UV stable, impact resistant and corrosion-proof, with a 25-year hardware guarantee. For you, that means fewer after-sales issues, fewer call-backs, and a product you can install and walk away from with confidence.

Designed to help you sell

While performance is key, design flexibility is what gets homeowners over the line. Our XtremeDoor range covers everything from traditional to contemporary looks, with a wide choice of colours, hardware and glazing.

To make life easier, the XtremeDoor door designer tool gives installers and homeowners a simple way to explore styles and options online. It’s a powerful sales aid that helps your customers visualise their door before you place the order.
