Polycarbonate

Polycarbonate roofs for conservatories come in three main thickness. 16mm triple wall and 25mm/35mm six wall.

At all costs do not have a conservatory built with 16mm polycarbonate. It does not have adequate insulation, with a ‘U’ value of 2.7 it looses too much heat and it is extremely noisy when it rains.

25 mm or 35 mm polycarbonate have pretty much the same insulation properties with a ‘U’ value of 1.5, although they will still be noisy when it rains, it is not as bad as the 16mm.

Polycarbonate is available in Opal, Heatshield, Clear and Bronze.

The main types of polycarbonate which we recommend are Opal for White conservatories and Heatshield for Woodgrain conservatories. Both give good light transmission as well as offering decent protection against heat build up. Unless the conservatory is in a shaded location we would not recommend Clear (not strictly clear more opaque), due to heat build up when the sun is out and the Bronze, due to the colour acting as a heat sink, we do not recommend at all.
