15 BRIGHT AND BREEZY
A healthy home needs a steady flow of fresh air and natural light. We asked Grant Sneddon, product manager at Velux, for his advice
Where’s the best place for windows?
When looking at the structure of your home or new extension, the role of daylight should always be a key consideration. Think not just about the number of windows, but also the direction they’ll face. Southfacing windows allow most of the day’s sunlight to enter your home.
What about roof windows?
Roof windows can let in up to twice as much light as vertical windows, because the glazing is angled directly towards the sun, and can also help to enhance views and allow daylight to penetrate into bathrooms and hallways. Take into account the pitch of the roof – the lower it is, the longer the roof window should be.
When it comes to choosing roof windows, a classic centrepivot design is ideal for lower installations, as they allow space for furniture to be placed beneath the frame. Top-hung versions are also worth considering, though. Opening outwards, with a handle at the bottom, they’re most effective where the base of the window is within reach.
Are there any other options?
Other options include sun tunnels, which are perfect for getting natural light into corridors, stairwells, bathrooms and cupboards, or under flat roofs where installation of a traditional roof window is not possible.
How many windows do I need?
There’s currently no legislation on exactly how much daylight a home requires, but the British Standard recommendation ( BS 8206-2:2008 Lighting for Buildings – Code of Practice for Daylighting) suggests a 20 per cent glazing to floor area ratio. Ultimately, though, it’s up to the homeowner. Most homeowners will always crave the lightest, brightest and freshest home they can create. velux.com
