We are looking at using 'polycool - Solar Control Inserts'
http://www.polycool.co.uk/ to help
control the temperature all year round for our conservatory roof.

The product looks good, but before I go ahead and buy, I'd be
interested to
hear from anybody who has had personal experience of the product, and
how
effective it proved to be.

Any pros and cons? Any alternatives?

Many thanks in advance,

Peter.
