Supalite Roof Review

Many people are frustrated by the wild variation in temperatures they experience in their conservatories. Quite a few have been tempted by a fairly new type of lightweight tiled roof featuring integrated insulation and artificial tiles or slates. The concept is epitomised by the Preston firm SupaLite (that’s Preston Lancashire, not Preston Devon by the way!).

So what are the pros and cons of SupaLite and similar systems (e.g. Guardian)? SWRCN had a look to see what all the fuss is about and create a SupaLite Roof Review.

SUPALITE ROOF REVIEW: THE PROS

One of the key properties of SupaLite’s system is its ultra-low heat transfer co-efficient (its so-called ‘U-Value’ or ‘U-Factor’). This is a value to quantify the amount of energy that transfer through a metre square area of material (or materials) divided by the temperature change across the surface. In simple terms, a high U-Value equals weak insulating properties and the lower the number gets, the more insulating the material or surface. To calibrate these figures, consider that a single pane of 4mm glass will give you a U-Value of 6 while triple-glazing is likely to reduce that to around 2). SupaLite claim that the U-Value of their conservatory roofs is a staggering 0.15 as standard, with an optional upgrade of 0.12!*

SupaLite is an example of a ‘warm roof’ system which actually integrates the insulation within the rafters of the roof (as seen on the video below). This stops warm air escaping the roof in the winter and avoids the direct conduction of heat in the summer, leading to a much more stable year-round temperature which is well within building control regulations.

Another advantage of SupaLite is its light weight (hence the name). Comprised of an aluminium framework on to which the tiles are clipped, the SupaLite roof can usually be installed on existing conservatory frames without the need for extra foundations (although you should always check with a building control body [BCB] first!)

Then there is the construction impact and duration. The light materials combined with an easy to assemble design means that the conversion process generally takes just a matter of weeks rather than months with very little mess and disruption.

Added to the above, there is the 60 year life expectancy of the tiles and the range of colours and styles available. SupaLite systems and similar lightweight tile/slate effect roofs can be easily adapted to fit the most basic lean-to or the more elaborate Victorian and Edwardian conservatories.

SUPALITE ROOF REVIEW: THE CONS

Of course, no roofing solution is perfect and there are a number of precautions to take before deciding whether SupaLite is for you.

Since the system is available to trade buyers as well as via approved installers, prices can vary significantly and are often higher than expected. Clearly, there are many factors that will determine costs but most homeowners will need to think in terms of £5,000 as a minimum outlay with some contractors likely to quote up to the £10,000 mark. Although the efficiency savings of a SupaLite roof can add up to a significant amount over time, this initial outlay may be a deterrent to some who may prefer to opt for a cheaper alternative.

Another aspect to think carefully about, especially if your conservatory was formally covered with a clear material such as glass or perspex, is that the installation of a covered roof – even a lightweight one – does seem to mean that your conservatory will technically become an extension (sun room) for building regulations purposes. However, a quick call to your local BCB should clarify the situation in your specific case.

Finally, some purists simply don’t like to use anything but traditional materials in the construction of their conservatories regardless of any energy savings they might make. Although a competently fitted SupaLite roof does look impressively authentic, it won’t be to everyone’s taste.

Titchmarsh Gives his Conservatory Plants Advice

Leave a comment

TV plant guru Alan Titchmarsh recently provided some sage conservatory plants advice in an article for the Daily Express. SWRCN have summarised the main points:

Titchmarsh’s Conservatory Plants Advice
  • Compromise Comfort and Luxury
    The first piece of conservatory plants advice from Mr Titchmarsh was to avoid the temptation to cram your conservatory with exciting exotics – at least without doing your homework. Many exotic plants require more than a mild climate and will struggle to survive the winter unless you are prepared to provide serious heating during the winter months. Other things to beware of, according to Titchmarsh, are lethal spikes, toxic saps and plants that attract lots of insects. One suggestion he made was to combine a few trees and shrubs with a single climber, citing Bougainvillea as a particularly popular plant at the moment (requiring frost-proofing only during the winter months)
  • Install Easy to Clean Floor and Furnishings
    Some exotic plants create a bit of a mess which is why another piece of conservatory plants advice from the UK’s best known gardening expert was to make sure your flooring and furniture can cope with everything from shed petals and leaves to sticky sap, pollen and spilt plant feed. In a nutshell, if you can’t wipe it down with a damp cloth, consider taking it out of harm’s way.
  • Honour the Olive
    If you’re looking for something popular, flexible and low maintenance, then you can’t go far wrong by getting hold of an olive tree, according to the BBC stalwart. Olives are a hardy plant and can be easily pruned and trained to fit your space. You might even be lucky enough to harvest some fruit – perfect to garnish your evening martini.

  • The Scent of Citrus
    With their large oval leaves and gently scented white flowers, citrus plants are an ideal way to add a zingy Mediterranean flavour to your conservatory. Titchmarsh does warn that citrus plants vary a lot in their susceptibility to cold, so make sure you do your homework to find out whether winter heating will be required or not.
  • Find Some Frost-Free Faves
    If you’re struggling for ideas about cold-resistant conservatory plants, Titchmarsh gave a list of some of his recommendations:

    • Abutilon hybrids – These upright flowering shrubs are from the mallow family and are known for their maple-shaped leaves.
    • Cestrum aurantiacum – An evergreen tree or shrub with  cheery orange flowers.
    • Constance Elliott – A hardy white version of the popular passion flower.
    • Passiflora edulis – This is the unmistakeable purple and white passion flower which will reward you with real passion fruits!
    • Plumbago capensis – An electric blue coloured wall shrub.
    • Trachelosperm jasminoides – An evergreen climber with distinctive white flowers.
  • Think Outside the Box
    A final piece of Titchmarsh’s conservatory plants advice is simply to do your botanical homework and then get creative. While it is always good to follow sound advice, no-one wants a carbon-copy of someone else’s ideas. Providing you follow the general tips above, there’s nothing wrong with taking a bit of a risk to achieve the effect you’re looking for – just as long as it doesn’t involve poisoning the pet cat with toxic leaves!

Plants and Conservatory Roof Conversion

Of course, it is easier to create consistent conditions for plants if you can control the temperature of your conservatory all year round. If your space ends up swinging wildly between hot and cold throughout the year then consider opting for one of Roofworx’s conservatory roof conversions. Roofworx South West are based in Torquay, Devon.
