- Will an insulated ceiling reduce outside noise from rain?
Yes. Outside noise levels will be greatly reduced meaning that you can work, watch TV and enjoy your conservatory even during heavy rain or when you are exposed to heavy traffic noise. A 2Hot2Cold conservatory ceiling uses insulation that has seven layers to provide U-value of just 0.175 and also includes a double lined uPVC cladding. In short, the technology used absorbs the noise.
