Upgrade Polycarbonate


Why Should I Upgrade My Polycarbonate Roof?

If your polycarbonate roof is over ten years old, it’s more than likely that its best days are behind it. Modern advancements in roofing for extensions, lean-to’s and conservatories have left polycarbonate behind. It might be time to consider doing the same.

We’re frequently asked to upgrade older polycarbonate roofs with with glazed or partially glazed roofing systems. Whilst polycarbonate roofs were once the go-to for conservatories and lean-to’s, there’s so much more we can do today with modern materials. The benefits go beyond surface level, as polycarbonate is expensive to heat and uncomfortable in summers and winters.

What is polycarbonate?

Polycarbonate (PC) is a naturally transparent amorphous thermoplastic. Conservatories, particularly those constructed before 2005, will likely have a polycarbonate roof. A particularly durable and flexible plastic, it was the go to product when creating extensions to allow light inside. In its day, polycarbonate was a fantastic building material, perfect for building roofs. However, advancements in the way we make replacement conservatory roofs have largely surpassed the ability of polycarbonate.

Should I replace my existing polycarbonate roof with a new glass roof?

For the most part, glass roofs are considered the best choice for conservatories. Modern glass roofs have risen in popularity over the last five years. Offering protection from noise pollution, glass doesn’t make the ‘drumming’ sound in the rain, like polycarbonate. Beyond this, polycarbonate can also creek and make popping noises as it heats up and cools down. Glass has a longer life expectancy and modern advancements use self-cleaning systems and heat retention strategies. The visuals are generally better, with the glass much more open and bright in the day and clearer at night. Using glass allows you to incorporate blinds, which we can run on mechanical systems, or build in between the panes.  At Whalley Home Improvements, we typically install the ClassicroofTM to replace polycarbonate.

Despite being much more durable than polycarbonate, the glass used in the Classic roof offers the same versatility and can be configured to fit any space.

Should I upgrade my polycarbonate roof with a solid roof?

If you’re looking for something a little more extravagant, a new solid roof may be the solution. Our solid roofs include glazed panels which can be fit to suit your home. This way you can capture the right amount of light for your conservatory, without having a fully glazed roof. At Whalley Home Improvements, we mainly install two types of solid roofs; the Ultraroof 380TM and the LivinroofTM .

Renovating an older conservatory can be a daunting task. With so many options available, it’s tougher than ever to decide on the style of your conservatory. The older polycarbonate material has a shelf life of a decade. That means, for most conservatories, the roof will need replacing in the near future. Glass and solid roofs will last much longer than the existing polycarbonate and they are much more versatile and visually appealing. Now might be the time to consider upgrading your conservatory.
