Hello,

Save these mentioned in an old posting here (found by Googlegroups):

http://www.lapvent.co.uk/

Seems to be a way to emulate breathable sarking without actually having to
refit the sarking and thus strip a prefectly OK roof.

The idea seems reasonable and easier than fitting tile vents, though these
are more expensive (but possibly needing less units).

So - anyone actually fitted them and did they work?

Cheers

Tim
