can anyone recommend
a transparent insulated plastic
that i can replace a small tiled subroof
about 3 yards by 2 yards in size
over the top of the stairs with,
and knock out the ceiling plaster,
so as to let some light through?

I could use the exisiting wooden framework
and bolt the plastic onto it.

I was thinking maybe something cellular about 3 inches thick
might be good.

and would i need planning permission
or building regulation inspection?

the subroof is out of view of any neighbours..

can i put a door in it
for easier access cleaning the valleys of leaves?

Has anyone got something similar ont he web i can look at please?

Look up 'light pipe'.

i have lit my pipe...

ive seen lightpipes - expensive cylindrical reflective tubes going up
but I want to bolt 4 sides of insulated transparent stuff
onto the existing woodwork
where the slates are now
maybe with a metal frame on the outside
to hold it down...

it doesnt have to be 100% transparent like double glazing
so it shouldnt be expensive
but i'd like it very insulated and waterproof...

wickes have
Triple Wall Polycarbonate Sheet
£36.99

Size: 3m x 900 x 10mm

http://www.wickes.co.uk/Roofing-Shee...spolyroofsheet



which is a lot more expensive than

Polycarbonate Twin Wall Sheet Opal
£7.47

Size: 700 x 10mm x 3m



and both would need several bits joined together somehow...



whats the difference in heatloss between the two,

what else is there usable?
