“Mention the word ‘rooflight’ and most people would think of a typical, hinged ‘roof window’ for use in pitched roofs, or one of the increasingly popular flat glass rooflights for flat roofed extensions.
However, the term ‘rooflight’ can be applied to a huge range of different products, all designed with the primary aim of delivering high levels of natural daylight to building interiors, but each offering different options in terms of aesthetics and functionality.
So, if you’re planning on a self-build project, or maybe looking to renovate or re-model your existing property, here are a few ideas to consider:
If your property has any areas of flat roofing, have you ever considered the possibility of creating a roof terrace? These are becoming increasingly popular in urban areas where living accommodation and outdoor spaces come at a premium – and rooflights can play a big role in their success.
First, you’ll need to consider the roof construction and confirm with your architect or builder that it can support floor loadings. Easy access can then be gained to your terrace using sliding box-type skylights.
These units are available in a variety of glazing configurations designed to be fitted within the existing building structure, together with an internal staircase from the room below.
They provide easy, secure access for regular use, plus the added benefit of natural daylight flooding into the staircase and the room below.
For maximum daylight utilisation below the terrace, you could also consider ‘walk-on’ rooflights, set into the floor substrate of the terrace. These make a stunning feature and a real talking point.
Non-slip, ‘obscure’ glazing can be specified for safety and privacy, without overly compromising light transmission. It is important to note, however, that walk-on rooflights are designed to floor loadings, so they are much thicker, heavier, and usually significantly more expensive than conventional rooflights (which should never be walked on).
Many older properties feature useful basement space which is often used only for storage, simply because without natural daylight, a basement isn’t a particularly pleasant place to spend time in.
Walk-on rooflights are actually see-through flooring. So what’s to stop them being used inside a property, to allow daylight to penetrate the floor? In this way, a properly tanked, waterproofed basement can be transformed into comfortable and healthy living space.
Positioning the walk-on rooflight in close proximity of an external window can deliver a high level of daylight to the basement below. Basements rarely extend beyond the external walls of a property, but where this is the case, the options are even greater, with the possibility of setting walk-on rooflights into paved external areas above the basement.
Everyone knows that on suitable properties, loft conversions are the simplest and most cost-effective way to maximise living space – and there are many options on the market for delivering daylight under roof spaces.
Dormer windows are an effective solution, but can be costly to construct and may contravene local planning regulations. For the majority of properties with pitched roofs, roof windows installed ‘in plane’ with the pitch of the roof, are the ideal and cost-effective solution. These can be hinged to allow ventilation and easy cleaning.
A wide range of designs are available, including ‘heritage-styled’ roof windows, which mimic traditional designs and may provide a solution for building owners in conservation areas.
A drawback for some ground floor extensions, is the resulting reduction in light levels in the room adjoining the extension. Carefully positioned rooflights can overcome the problem, bringing high levels of natural daylight to the extension and the adjoining room, as well as providing an attractive feature.
For flat-roofed extensions, lantern-type designs, or the very popular flat glass rooflights, are ideal. It’s worth remembering that depending on the size and aspect of the room, rooflights can deliver up to three times the amount of daylight compared to vertical windows.
For areas with ceilings under a pitched roof, ’light tubes’ can provide an effective solution. These are rooflights mounted over a reflective tube which penetrates the roof cavity and delivers daylight via a translucent fitting in the ceiling of the room below.
The first and obvious function of every rooflight, is to increase light levels. However, with so many designs available, there are countless options for creativity.
As the UK trade body representing rooflight manufacturers, NARM (National Association of Rooflight Manufacturers) is made aware of interesting rooflight applications all over the country.
One fascinating and possibly unique example is a private home in Scotland with a home observatory, facilitated by an opening rooflight which allows a high powered telescope a clear view of the sky.
In others, rooflights have been positioned to create aesthetic features or changing lighting effects. Others still feature automatic opening mechanisms, connected to rain sensors, thermostats, remote controls and even software-controlled building management systems. The possibilities are endless.
