When considering glass or polycarbonate, there are a number of things to take into account. Glass conservatory roofs will achieve a more comfortable living space, are aesthetically more pleasing and glass is more resistant to weathering. Polycarbonate on the other hand is a lot cheaper than glass and is not translucent unless clear polycarbonate is opted for. Polycarbonate also tends to be very noisy especially when raining. This is another benefit of a glass conservatory roof.
