Polycarbonate conservatory roofs
A polycarbonate roof is created using layered multi-wall plastic sheeting with an air gap between the sheets that helps to trap warm air. The plastic is half the weight of glass so you won't need a reinforced frame and can be used to create a lightweight structure quickly and cheaply.
Lightweight and structurally stable, polycarbonate is affordable but isn’t a material that we recommend for a domestic conservatory.
At one time, all conservatory roofs were polycarbonate but they suffered from leaking, overheating and poor sound insulation. The aesthetic is poor and a conservatory with a polycarbonate roof could devalue a property as it can be off putting to buyers.
At Everest, we only ever suggest polycarbonate for an outbuilding as a last option.
