See the infographic below to determine whether your shed needs a vapour barrier between the roof or walls. A breathable membrane underneath any garden building's flooring is always a good idea. In terms of money that can be saved, energy use and reducing the carbon footprint, installing roofing insulation is well worth the investment. It’s especially crucial for timber as the material is prone to moisture build-up . Without proper insulation, the panels will invite both cold and hot air in, plus moisture. This also limits the functionality of your storage building at a certain time and season.

Overlaps of the VCL membrane are sealed together with Double Sided Tape and the face of the joint sealed with Single Sided Foil Tape. Our breathable multifoil insulation range provides foil insulation, breather membrane, and radiant barrier all in one layer. Vapour Control Layers and vapour barriers are essentially the same thing. Some people and organisations will refer to the material that controls vapour movement as a VCL and some will call it a vapour barrier.

As with all insulation retrofits, it is also important to consider the existing ventilation levels within the space, how the new insulation layer may affect this and consequently whether additional ventilation is needed. This can be supported through air-leakage testing." How much does it cost to insulate a concrete floor? So how about existing concrete floors? Adding insulation beneath, as is commonly the case with a new concrete floor, can be costly and disruptive, but there are alternatives. Digging out an existing concrete floor to add insulation is an effective yet very disruptive solution. (Image credit: Getty) Are there any tips when installing a concrete floor?

I would recommend that if a floor is to be replaced and insulated, that a test hole is cut initially so that an assessment can be made which will result in a more accurate cost estimate. It would actually be rare for a house built post 1990 to have the concrete floor replaced as the cost involved will most likely outweigh the value of the energy reduction.” If the cost and disruption of taking up floorboards cannot be endured, and there is no access to the space below the floor, then insulation must be done on top.Insulating a building is important to reduce overall energy usage,” explains Rob Bohm. “Around 15% of heat loss from a building can be through the floor. Houses with concrete floors built prior to 1990 would certainly benefit from having insulation fitted.”
