Easy to install with no drilling or damage at all to the
roof, inserts are completely maintenance free and will last the life
of the roof.
Generally speaking for a conservatory to be comfortable
the temperature should be controlled to between 64°F and 84°F
(8°c-28°c). An additional benefit is that roof inserts also
prevent heat loss in the winter thus making it more useable and reducing
heating costs.
