Composite doors

Our composite doors are made with a rigid polymer subframe, high-density CFC-free polyurethane foam core and impact-resistant GRP skin as well as an anti-snap, bump, pick and drill cylinder.This makes for an extremely durable, dense and robust product, with high-quality materials which combine to create the perfect entrance for your home.

Composite doors are excellent at protecting their wooden heart from rain and wind and whatever else the great British weather throws at them. They can go on performing for decades, without fading or warping. It is a great-looking design that keeps on looking its best.

Timber is a natural insulator and it’s hard for cold air to get through composite doors. As for the other layers, versatile uPVC, which shrugs off bad weather, is the most common additional material. But others could feature in your composite door – including laminate to add strength, or resilient fibreglass.

The internal space of the door is often injected with a warm foam core providing heat-retaining insulation to boost the door’s energy efficiency.

Benefits of Composite Doors

  1. Durable and strong

With an insulating foam core, and a composition of multiple layers, composite doors have a great deal of strength and resilience far exceeding police-approved security standards and making them ideal in just about any residential setting.

  1. Virtually maintenance free

Keep your doors looking their best without expensive maintenance. There’s no warping, cracking, fading or repainting – just a quick wipe-down with a damp, soapy cloth is all that is required.

  1. Great thermal efficiency

Heat can’t escape, so you should see a difference in energy bills and enjoy having a warmer home. These doors also provide an effective noise barrier, making them ideal for busy areas or main roads.

  1. Enhanced security

With effective locks and a super-strong frame, a composite door keeps you and your family, and your home, safe and sound.

  1. Choose the perfect colour for your home

There is an extensive array of front-door colours. Brighten up your home and boost kerb appeal with something altogether bolder. You can also personalise your door with smart-looking hardware.

  1. Protection from the elements

With powerful weathertight seals, you keep out draughts and anything else the weather might throw at your doors, all year long.

Composite doors from Isis

Your front door is one of the first things people will see when they approach your home, so it’s worth making a great impression to boost “kerb appeal” especially if you’re thinking of selling your home.

We’ve been fitting front and back composite doors in Oxford and across Oxfordshire for more than 25 years. We offer high-quality products from trusted, well established suppliers. Our doors offer 48mm thickness for added security and insulation, a colour palette of up to 20 shades plus myriad different choices when it comes to hardware for your door.

The range incorporates letterplates, knobs and handles as well as a number of varied glazing choices.

We have the following composite door collections from which to take your pick.

The Traditional Collection

This range of composite doors incorporates a stunning line-up of products offering the best of both worlds – combining the finest older and modern styles. Ideal if you want to add a touch of character to either a rural or modern property or one more recently built.

Add extra features with a great choice of hardware items, whether you’re after a lion-style door knocker or a Gothic letterplate.

The Contemporary range

While many of our products suit properties of any period, whatever their location, some of our composite doors definitely look better in a more modern setting. The Xtreme Cottage Four model, for example, is a hugely popular contemporary option, with a choice of lock and centred or hinge-side glazing positions.

Meanwhile, our Napoli offering is a striking, modern design with a subtle Art Deco influence and, again, it’s a very popular choice with our customers. Then there’s the Stuart, a no-nonsense design with a single glazed panel, centrally placed or offset that allows your home to make a very modern statement.

If you’re after something with a more European design flavour, check out our Jacobean door, with inline slim glazing details inspired by the contemporary continental look. The Verona is another product bringing your home bang up-to-the-minute with linear etched detailing, either with glazing or as a solid door.
