The original conservatory had a polycarbonate roof.
It was unsuitable for the winter, as the conservatory is on the north side of the property and therefore much colder.
The new solid tiled roof will provide the energy efficiency to solve the cold in winter.
This Solid Tiled Roof has a U-Value of 0.15 and is 19 times more energy efficient than the original polycarbonate roof.
