Patio Doors

Our composite doors are designed to address the common issues associated with timber doors, such as swelling and warping. A standard composite door is typically constructed using a combination of materials, including uPVC, foam, wood, and GRP (glass reinforced plastic).

However, our Rockdoors are unique as they are constructed using PVC for the door sash, inner frame, and outer frame, along with a solid insulating core. This integrated design ensures that the materials function as one unit, providing optimal performance, exceptional security, durability, and energy efficiency.

Our composite doors are exceptionally secure due to their robust construction, multiple layers, and advanced locking systems. Additionally, our Rockdoors feature a 4-hook lock system* and are reinforced with mesh for added protection.

Composite doors are typically crafted from a mix of materials like wood, uPVC, and glass reinforced with foam or other insulating cores. However, our Rockdoors are purposefully not produced with timber, they are instead made from high quality PVC for the door sash, inner frame, and outer frame, in addition to a solid insulating core. The high-density core is 60% stronger than standard composite doors on the market.

Our Rockdoors are also available to upgrade with a unique Steel Security Mesh reinforcing. The mesh is enclosed in-between the door surfaces to ensure your door cannot be cut through by a burglar — an increasingly common form of entry!

The cost of a composite door varies depending on the design, size, and any additional features you choose, but they typically start from £1,000 or less. It’s important to be cautious of cheaper alternatives, as many composite doors may not be suitable to withstand the challenging Cumbrian weather. We take pride in being Cumbria’s exclusive Rockdoor supplier, and our doors are equipped with a harsh weather pack to ensure their durability.

While uPVC doors are the more budget-friendly option, composite doors offer enhanced security, and insulation, and are available in a variety of colour and style options, making them the more aesthetically pleasing option.

Providing you’ve invested in a quality composite door and had it professionally installed by a reputable firm, you can expect these doors to be highly durable, with an average lifespan of 30–40 years. This means you can enjoy the peace of mind that your door won’t require replacement for a considerable period.

No, composite doors are very low maintenance. They won’t warp, crack, or fade like traditional timber doors and only require occasional cleaning with soapy water to keep them looking their best.

Yes, composite doors are a worthwhile investment due to their durability, security, and energy efficiency. Unlike traditional timber or uPVC doors, they are built from multiple materials, making them stronger, more weather-resistant, and longer-lasting. While the upfront cost may be higher, their low maintenance and long lifespan make them more cost-effective over time.
