Product Information

Fibreglass wool is an efficient insulator but can cause you harm without proper safety equipment (it’s also pricey!). Uneven and irregular rafters mean that it becomes impossible to tightly fit rigid board insulation. Flexible multifoils can cope with this, as well as providing an airtight construction method that compensates for the deficiencies of other insulating materials.

Interstitial condensation can occur in insulated lofts which have non-permeable roofing felt. This results in white fluffy mould on the underside of the roofing felt. Using our range of breathable multifoil insulation saves you from completing unnecessary work. Our breathable lining range means you only have to install one product to protect and insulate. Multifoil insulation will always be the ultimate convenient solution since it is reflective and water-resistant without additional measures. You could easily reduce the time it takes to insulate your new build project.Mengnan Jiang, Yang Wang, Fayu Liu, Yuchao Li, Huanhuan Zhang, Steven Wang, Chin Pan & Zuankai Wang In each case, these documents set target insulation (thermal performance) levels that you should look to achieve depending on the work you’re carrying out. The U-value you need to achieve will depend on where your property is located, and whether you are retaining the existing floor slab (and installing the insulation above it) or digging it out entirely. If these are not achievable, the Approved Documents and Technical Handbooks set out some specific scenarios where you can target a worse U-value." Cabins go by similar principles to normal buildings, though many opt to insulate them from the outside, to preserve the look of the exposed rafters. You’ll need to use a moisture-resistant sheet underneath the insulation boards. How to Insulate a Curved Roof

Moving in 2002 to a small-holding in South Wales, providing as it did access to a wider range of natural resources, fanned his enthusiasm for sustainability. He went on to install renewable technology at the property, including biomass boiler and wind turbine. At the time, insulation was also largely unheard of, and almost as much heat escaped through the floor as through the walls. With a vapour resistance of 0.115MNs/g, our range of breathable roof membranes offers the same benefits as a traditional breather membrane but with the bonus of thermal properties. This means you can always be confident using our product, knowing it will not cause any condensation issues.Any joints will need to be sealed with Single Sided Foil Tape. Remember, it is very important to seal everything and not just sections of VCL membrane. These include the ceiling joint, floor joint and any vertical joints where the VCL meets adjoining walls. As well as foil tape, expanding foam is another possible option for this. Masonry/wood primers combined with tape is another option. Heating and cooling buildings accounts for 35-60% of total energy demand around the world . 2 The savings homes or businesses stand to make by reducing energy bills can more than make up for the costs of roof insulation. Note on VCL: Although the use of a VCL is recommended, there is an argument that it is not necessary where breathable insulation is being used. If the floor timbers have survived since the house was first built, then the ventilation under the floor is working and a VCL is not bringing anything to the party. How Does Insulating Suspended Floors Affect Ventilation? When laying a new concrete floor, a thin later of screed will be added on top of the underfloor heating pipes, should you choose to fit them.

During the construction process, a damp proof membrane will be laid over a layer of sand, before insulation is placed on top, and finally the concrete is poured. If you are fitting a wet underfloor heating system, it will now be laid on top of the concrete sub floor with a thin screed layer poured over the top. If the floorboards can be lifted, then this provides the best opportunity to insulate and draught proof. Insulation should be inserted with a snug fit between the joists. Ideally, this will be a breathable insulation (sheep wool, wood fibre, hemp, etc.).The insulation must be thin to avoid affecting door opening height.There are a number of thin insulators, like Sempafloor, warmup boards, or wood fibre boards, that could work in this instance. Rigid foam insulation boards can work as well but are less forgiving of foot traffic.
