Transform your loft into a warmer, more comfortable living space
If your home has a room built within the roof space, poor insulation can allow a significant amount of heat to escape through the roof, making the room uncomfortable during winter and excessively warm during summer.

How room-in-roof insulation works
High-performance rigid insulation boards are installed within the roof structure to create a continuous thermal barrier that significantly reduces heat loss. Depending on the construction of your property, insulation may be installed between and over the rafters to maximise thermal performance while maintaining valuable internal living space. The insulated areas are then professionally finished with plasterboard and prepared ready for decoration, leaving a clean, modern finish with minimal disruption.
