Extensions remain a popular choice for renovators, whether to the rear or the side, single or two storeys or up into the loft. Increasing the square footage adds value, but it is also a great way to enhance the property and living space within.
A successful extension will bring in more natural light, provide extra living space, improve flow and often open the house to the garden. Glazed products are central to achieving this; rooflights, roof lanterns, lightwells and patent glazing all maximise light during daylight hours.
Whether atop a single-storey extension or nestled in the roof above a loft conversion, these glass roof products offer exceptional light levels, which contribute to a healthier and more energy-conscious home. They are proven to deliver up to three times more daylight than a vertical window.
However, renovators must factor in location, orientation and gradient as part of the design process. These are all critical considerations for avoiding glare and unwanted solar gain.
Rooflight manufacturers combat solar gains through high-performance glazing. They will work with the project architect or homeowner to recommend the best glass for the site. There are many options, both coated and uncoated. Solar control glass, for example, can help retain heat in cooler months, which helps improve the property’s energy performance.
Energy savings
While fundamental to the function of an extension or loft conversion, glazed roof products also meet modern consumer demands. Currently, reducing energy costs is a big motivator for home improvers.
According to the 2023 annual UK Houzz & Home Study of more than 2500 UK respondents: “Homeowners are committed to their current homes, and we continue to see investment that help spaces to function better for the long term,” says Liza Hausman, Vice President of Industry Marketing at Houzz. “We’re also seeing an increased focus on efficiency, with homeowners making upgrades that will conserve energy and keep associated costs down.”
Glazed roof products can help with this. By allowing natural light to pour into the space below and lighting areas out of reach of vertical windows, they reduce dependency on electric lighting, thereby cutting associated energy costs.
Choose a popular material such as aluminium for the structure, too. Due to narrow sightlines (slim aluminium bars that make up the frame), the glazed area is maximised and lets in more light. The use of a thermally-broken aluminium bar also significantly reduces heat transfer and stops cold bridging, which adds to the property’s thermal efficiency.
Healthy and happy homes
While evidence proves the power of natural light to reduce energy costs and enhance building performance, there is growing emphasis on its ability to improve occupier comfort.
Daylight is hugely beneficial for our physical and psychological wellbeing. Natural light is more dynamic than electric lighting; it changes constantly, which can be more stimulating. This not only boosts mood and morale but can help combat fatigue.
Daylighting is now considered one of the most powerful tools in building design. Providing diffused illumination, it helps us focus, promotes productivity and maintains our daily cycle of activity and sleep known as the circadian rhythm.
Glass roof products are ideal for boosting the level of natural light inside the home and creating better connectivity with the natural world.
Which rooflight?
Glazed roof products work equally well on new-build properties and period and Mid-Century homes. Off-the-shelf rooflights are a less expensive option, but their use and suitability depend on the size, location and scale of the extension. They may be better suited to loft conversions rather than side or rear single-storey extensions, which call for larger expanses of glass.
An architect can advise on the most suitable rooflight, but we would also recommend engaging with one or several rooflight manufacturers early in the design process to choose the best option. When researching, consider their product range. Is it limited? Do they provide a bespoke service? Do they buy in from a manufacturer or do they design and make their own products, giving them greater flexibility?
Quality is also a critical factor. Look for proven performance and independently-verified test certification for weathertightness, resistance to snow and permanent load and thermal performance.
Pay attention to material choice, too. Aluminium is truly the best option for any roof glazing solution. Slim sightlines, durability and superb aesthetics make this a desirable, premium option for homeowners. Then, of course, there’s the option to choose from thousands of colours and textures for the powder-coated finish.
