When choosing a rooflight, you will be presented with two main options: glass or polycarbonate. Many of our clients wonder which option they should choose, especially if they haven’t selected a rooflight before and aren’t sure about the ins and outs of the different types of materials. To help you decide, we have put together a brief guide to glass and polycarbonate rooflights and their key features and benefits.
Polycarbonate is a type of plastic that can be moulded easily, so it is often used in construction. It is particularly popular with rooflight manufacturers because it is so lightweight, yet at the same time, very strong.
Who chooses a polycarbonate rooflight?
• Perfect for keeping to a budget. Polycarbonate rooflights tend to be priced lower than glass rooflights. This makes them an excellent option for tradespeople, or for use in a commercial space where keeping to a budget is paramount.
• Very strong and durable. Polycarbonate materials have undergone rigorous testing and have been proven to be virtually unbreakable. Even if they are broken, they will not shatter, making them a safe option for homes, businesses and public spaces.
• Lots of natural light. The rooflights make use of a domed shape, which helps capture as much natural light as possible and filter it down into the room below.
• Thermally efficient. Choose triple skin polycarbonate to boost thermal performance and make your polycarbonate rooflights more environmentally friendly.
The glass used in rooflights is strong and versatile, with various options available to meet the requirements of your project. Many of the most modern, low profile rooflights on the market are made of glass, allowing you to achieve a premium aesthetic.
Why choose a glass rooflight?
• Appearance. Glass will be crystal clear and will allow in plenty of natural light – it will look sparklingly bright and beautiful.
• Condensation resistance. Make sure you choose glass that is thermally efficient to minimise the risk of condensation even further. Sealed double glazed units must be carefully manufactured and installed if you want to keep them free from damp.
• Options for additional thermal performance. Choose glass with low-E coatings and argon filled cavities if you want to achieve the lowest U-values possible.
• Noise reduction. Glass will perform well when you need to reduce noise, and it is possible to install secondary glazing with an air gap to improve acoustic performance even further.
All in all, glass and polycarbonate rooflights have lots to offer. Both can make an excellent addition to a home, business or commercial space, and the main factor will be personal preference.
