Room-in-roof insulation

Priority for Completion: Low

This recommendation is triggered when a room-in-roof style construction is present and there is no evidence of it having been insulated. The exact benefit will depend upon a wide range of factors including the heating system, the cost of the fuel and the occupancy of the home together with the room's size and shape. Generally, insulating a room-in-roof constructions can prevent a significant amount of heat lose from a property so the savings can be substantial. Additionally, good design and insulation is likely to make the room more useable reducing the temperature during the summer. However, installing room-in-roof insulation usually requires significant investment and works. Typically, ceilings will have to be removed to fit new insulation. There are also other factors to be considered so expert advice should be sought. As such we have rated this as being a recommendation of low priority for completion.

However, where appropriate, we would strongly recommend that insulation is installed as part of any major home refurbishment.

Room-in-roof insulation is usually applied to the internal surfaces of the structure. Once applied it will be covered over, usually with plasterboard and plaster. Many plasterboard panels are now available which come ready insulated on the reverse.

Obviously fitting internal insulation usually requires redecorating and may reduce room sizes depending upon the type and quantity of insulation installed. The impact of this reduction is most significant in small rooms but is not likely to be a major consideration in larger spaces. It will also require the removal and refitting of anything fitted to the walls being insulated which can be a particular consideration in rooms like kitchens.
