A typical fully installed system will be anywhere between £900 and £1,400 inc VAT

has any of your solatubes leaked? any issues with them?

Hi there, I can say with complete confidence that we just don't get leaks. I've been installing for the last 14 years, as solatubesouthwest.co.uk, and still enjoy what I do enormously and take great pride in my installations. The Solatube is a very well designed sun tunnel and in my opinion the best on the market by a long shot. Solatube is also the only company that has continued to develop and improve on it's original design, year after year. Ultimately, a Solatube or sun tunnel system can only be as good as the installation, so ensure that whoever, installs it knows what they are doing. Unfortunately I come across far too many systems that have been bodged and consequently cause problems. So please ensure it's installed by someone who follows the instructions, rather than trying to guess how it should go in.

@@nigelbeale6222 is the strength/lux of light determined by the length of the tube? Thank you in advance sir

@@Timerooy Correct; the longer the tube, the less light is delivered at the end. This is because each time light bounces, or reflects, down a tube, it looses some of it's energy, which in this case is light. Hence why the reflective material used in a sun tunnel is so important. Even sun tunnels using 98% rigid reflective material will deliver significantly less light than a Solatube sun tunnel which uses 99.7% rigid reflective material. It may not sound like a big difference but consider this: • Each time light bounces it loses either 2% of its light with 98% material, or just 0.3% with 99.7% tubing. • So, over an average tube run of say 10 bounces 98% reflective tubing loses a massive 20% of the light • 99.7% reflective Solatubes lose just 3% over the same tube run • That’s a BIG difference Flexible tubing that some systems use is next to useless and you would need 10 flexible tube systems to deliver the same amount of light as a Solatube. But there are other factors that determine strength of light and the most significant one is whether the system uses a dome on the roof or a flat glass collector. Whilst a flat glass collector is unobtrusive it is also dependent on light shining directly down it, whereas a dome on the roof gathers ambient daylight from all around and directs it down the tube, i.e. it gathers much more light, all day long and all year long, including whenever the sun is not shining directly down it. A flat glass collector really only works when the sun is directly overhead, which is during midday, particularly in the summer time. During the rest of the day in the mornings and evenings and throughout the winter months, when the sun is lower in the sky, the daylight just can’t get inside the tube that well. Therefore one would need to specify a much bigger diameter flat glass system to obtain the same amount of light as one with a dome.
