Insulating a roof can be done through one of two methods; either by building a cavity between the roof and the ceiling of the rooms below, which can then have insulating materials added to, or you can use insulating roof panels.
Both of these options have their advantages and their limitations, such as with cavity filling, you need a cavity, and with roof panels, you don’t get as much insulation, so it’s important that you carefully consider your options.
Insulating roof panels are a great option for those homes which don’t have a cavity between the higher most room’s ceiling and the roof, as it will provide some insulation for a home which would otherwise have none. It can also be used to supplement a cavity insulated home with additional insulation. They come in various widths, giving you different specifications for the quality of insulation you want.
Doing cavity insulation for your roof also presents some options, usually pertaining to the material used for insulation. Different materials provide different levels of insulation, and depending upon the weight of the materials, you may be limited on which type and the quantity of insulation you can place below your roof.
