Velux sun tunnels

[Canski]

Has anyone installed these into their build ?

 

I have a bathroom without and a landing with limited  natural light and was considering a sun pipe. I had a quote and it seemed high and the 'window' on the roof was bit ugly. The velux ones are a little cheaper ,look a bit smarter and having used their products over the years I like the quality and ease of installation. Only problem is the pipe would need to be about 4 m long to get to the south facing roof.

I did some work on them for a company called Monodraught.

I still have a couple of the mouldings kicking about.

 

It is not necessary to have the reflective tubes, boxing and mirrors can work just as well.

Think periscopes.

I just looked at the mono draught ones. The dome looks like a diamond is this for a reason ? I won't have time for boxing and mirrors so just wanted a nice shiny pipe.

Interesting, I wonder if you could use them into a basement.

I think I read that the velux pipes can be extended up to 6 m so I don’t see why not

Here is a picture of the Monodraught parts I prototyped in the 1990s.

They are only circular to match the pipe, and only domed as that is what they wanted.

Prototype vacuum forming is relatively cheap to do as the former can be timber.

Need to be careful of the u value. For the moondraught it seems the standard one is 1.66 w/m2. It is quite a small area though.
