Composite Doors Installed by SRJ Windows

No home improvements better encompass the marvels of modern engineering like contemporary composite doors. These incredible products are crafted from a delicate combination of materials that truly capture the feeling of an old timber door while protecting your home from the structural weaknesses that plagued this outdated material.

As a Official Ultra Installer, our specialists have plenty of experience and all the relevant qualifications when it comes to market-leading composite doors. Get in touch and ask us yourself; you’ll be in good hands with SRJ. We can even offer you one of Stirling’s most eco-friendly installations thanks to our SEPA accredited status.

Premium Composite Doors Profiles

There are a number of reasons to work with SRJ, but the sheer quality of our composite doors profiles is absolutely one of them. Our doors are specifically designed to offer you all of the features and benefits that can be expected of a market-leading product, so read on to find out more about the amazing profile that we choose to utilise in our installations.

Rockdoor Composite Doors

The Rockdoor profile is an industry-renowned design that outclasses competing products in terms of security, thermal efficiency and aesthetic appeal. These composite doors are 35% stronger than the average door currently circulating the market and will therefore protect you and your home from both unwanted visitors and the harshest of weathers.

The Rockdoor manufacturing process can consist of a combination of Glass Reinforced Plastic (GRP), timber and PU Foam. All of these are structurally impressive products in their own right, and when combined into one unique profile, they form the Rockdoor composite door. This impressive design is then further improved upon with the addition of carbon fibre and aluminium.

This is then modified even further with 3-star cylinders and S-Glaze glass, all of which ultimately results in our composite doors meeting the Secured by Design accreditation. You’re also protected from unwanted background noise thanks to the thick profile which provides a sound-cancelling effect. Ultimately, the Rockdoor is the go-to choice for keeping you safe in the privacy of your own home.

Near-Impenetrable Composite Doors

Composite materials are incredibly durable in their own right. When bolstered via our state-of-the-art manufacturing process with the latest heavy-duty locking mechanisms and hinges, they produce one of the strongest and most secure composite doors on the market. You’re protected from unwanted visitors with SRJ composite doors.

Our composite doors can offer much more than that however, and in fact will protect you against the elements as well. Heavy rain, howling winds and hefty snowfall are problems of the past when you choose SRJ as your installer. Our products are weather-proofed and finished to all but eliminate the threat of warping, rotting and condensation.

Energy-Efficient Composite Doors

Modern double glazing is notable for its thermally resistant properties, and therefore they are widely sought after when customers are looking for high Window Energy Ratings (WER). In fact, SRJ Rockdoor composite doors are capable of achieving A++ on the WER scale, which easily makes them some of the most impressive and cost-effective products around.

The benefits of a warmer home are numerous. Of course, you’ll experience a more comfortable living space, and this will be particularly noticeable during the winter months when you’re trying to keep your home as warm as possible. However, this will also result in you reducing your reliance on central heating, in turn dropping your monthly gas and electricity bills.
