−	If you have ever needed conservation rooflights for your project, the chances are that you have searched online and found plenty of choice. But what is a conservation rooflight and are they all the same? To better understand what makes a rooflight a conservation style, we must grasp the history behind this type of glazing and why the design is so sought after, not just on period properties but on more modern projects too. Without the ingenious concept of a rooflight, transforming unconventional space into a well-lit property would be a daunting task, and in some cases impossible. Although rooflights, or skylights as they are sometimes known, have been around for centuries, they became more prominent during the Victorian era as technology and building aspirations were stretched and roof glazing boomed.

One of the most famous Victorian building projects was Crystal Palace which, in 1851, used glazing on an unprecedented scale to showcase what could be achieved.

	Mass-produced Victorian rooflights for residential use tended to be made from cast iron and had smaller, lighter panes of glass. This was partially down to limits of glass technology, but also because of excise duties, which were imposed on glass by weight at the time. These slim, single glazed rooflights with multiple panels of glass were unobtrusive in design and sat flush in the roof. Today, it is this minimalist appearance that many seek to achieve with their glazing designs.

	If a conservation rooflight is all frame, then there is little point in having one. Genuine conservation designs should be manufactured with slim, clean lines and a low-profile to match the roofline. A number of skylight companies try to produce conservation rooflights using modern, bulky aluminium profiles. It is widely accepted that most authentic conservation rooflights are manufactured from steel because the material provides great strength while offering a slim profile and excellent glass-to-frame ratios.

	Some conservation rooflight suppliers are keen to boast about offering triple glazing in their products, but while this does offer a slightly improved thermal performance, it comes at the expense of appearance. The optimal spacer bar thickness is 16 millimetres, so any decent triple glazed unit is going to be almost 50 percent thicker than a double glazed version. With a flush fitting profile being one of the main requirements of a conservation rooflight, the introduction of triple glazing makes these rooflights almost impossible on some roof types.

	If you are looking for a close replica of a Victorian rooflight then a top hung profile will be the one you should opt for. Not only does a top hung design offer a more authentic appearance, it also maximises the space below due to the casement not sticking into the room. Smaller top hung rooflights also utilise beautiful brass ironmongery to operate the casement, whereas centre pivot designs tend to rely on modern plastic handles, which are out of reach and offer nothing to enhance the internal aesthetics.

−	Is any old conservation rooflight suitable for my project? Just because something is sold as a conservation rooflight, that does not automatically make it suitable for all building types. If your building is listed or in a conservation area then the criteria for using conservation rooflights are much stricter and you should always gain approval, not only for their use but also for the manufacturer that you want to use.	+	= Is any old conservation rooflight suitable for my project? =

	There are only a handful of companies that specifically make conservation rooflights and even fewer who design, manufacture and assemble them in the UK. Many conservation rooflights available online are simply other products which have been spruced up to look like they meet the requirements of that type of product. If you ask a supplier what the main difference is between their conservation rooflight and those used on modern buildings and the answer is a stuck on glazing bar, then you should avoid this supplier at all costs. Likewise, there are many elements which go into a genuine conservation design and price is always a reflection on quality.

−	Is there anything else I should consider when choosing my conservation rooflight? With the UK government pursuing a carbon neutral environment it is imperative that every action is taken to reduce energy consumption. Rooflights are energy efficient as they let in large amounts of natural light, thus reducing the need for artificial lighting. Remember that bringing natural daylight into your home is about much more than creating a bright, welcoming environment, it is about protecting your health and wellbeing and achieving a more positive way of life.	+	= Is there anything else I should consider when choosing my conservation rooflight? =

You might think that a conservation rooflight with a frame size of 900 millimetres wide and 1,200 millimetres high would have a similar clear viewable area regardless of the manufacturer, but you would be wrong. Bulky-framed modern types and flat rooflights posing as pitched conservation styles will let in considerably less light than a genuine steel-framed version.

	Victorian rooflights would have been single glazed, but today’s modern building standards are much higher and so single glazing does not meet the minimum requirements for thermal efficiency. Double glazing is the most popular option for genuine conservation rooflights because glazing technology means modern double glazed units can provide a number of benefits while remaining reasonably slender.
