Older properties such as churches, barns and listed buildings frequently present problems that don’t always match the standard insulation solutions for pitched roofs. Boarded roofs, shallow or uneven rafters, lath and plaster ceilings and retained old building materials are features often encountered in these types of property. Physique & Mécanique des Milieux Hétérogènes, UMR 7636 du CNRS, ESPCI, PSL Research University, Paris, France 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.

A Vapour Control Layer, or VCL for short, is a plastic layer that restricts the movement of warm, moist air from inside a property into the fabric of the building. The walls of your shed actually account for one of the smaller amounts of heat loss. On average, around 24% compared with around 40% of heat loss occurring through the roofing. With that, it’s crucial to look at your internal and external wall panels . Mengnan Jiang, Yang Wang, Fayu Liu, Yuchao Li, Huanhuan Zhang, Steven Wang, Chin Pan & Zuankai Wang If you are insulating floors in a renovation project, they go on to say: “if you are replacing more than half of a floor then you have to insulate to these standards whether you planned to or not.” However, it’s important not to restrict the ability of traditional building materials and structures to ‘breathe’ as this can often lead to problems. Adding non-permeable insulation over a ceiling, for example significantly reduces air movement in the roof space - considerably dropping the amount of evaporation that can take place within the roof.Here at SuperFOIL insulation, we are committed to increasing our sustainability in all our processes.

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? Hello, carrying out a listed barn conversion to have a vaulted insulated roof. no drawing sections received from architect. There is no felt between rafters & I have instruction not to raise or lift existing tiles. What method would you suggest fixing from the internal side of the roof. I was thinking, ridged board between rafters, tax silver under rafters stapled, battens over with plasterboard fixed, I'm concerned this method could still allow a possible leak. What are your thoughts??? Thank you. Laboratory measurements were made of the apparent R-value/inch for each insulation product and then the results were used to determine the apparent R-values of the three insulation arrangements for this study. But with the right insulation, it’ll prevent warm air from drafting out through the floor. You can be confident your shed will stay productive throughout winter. This also enables you to transform it into a functional garden office , for instance. Types of Insulation Materials

Why choose ROCKWOOL solutions?

When talking about floors, a vapour control layer is positioned at a different level to the damp proof membrane so generally you wouldn’t be able to substitute one for the other. Can you use a DPM as Vapour barrier? Lath and plaster ceilings are very moisture permeable and so the risk of condensation using non-breathable insulation is increased, and installing a vapour barrier isn’t usually an option. If you have 50mm or more of rafter space above the ceiling, however, you can install an insulating breather membrane instead of a conventional breather membrane. Battens can be simply pushed into place, they should have a side with a paper facing or a vapour control layer. This side should be facing into the loft and can be stapled to the joists to hold the insulation in place. Make sure that you do not over-compress your insulation batts, as this can lessen their ability to insulate. If your insulation does not fit properly without compression you should cut to size for a better fit. 4. Vapour Control Layer Saranadhi, D. et al.

Insulating concrete floors to the required standard will help cut your energy bills as well as make your home feel more comfortable overall — but how is it done? We asked the experts Thanks for your comment. You can discuss your project specific requirements in relation to TLX Gold through the following link: Now, what about insulating shed floors that are already in place? There are two ways to ensure that heat gets retained in your plastic garden storage shed , for instance. 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. Again this decision also depends on different factors. These include the complexity level involved in the chosen wiring plan, for instance. If properly researched and well-prepared, you can install low-voltage electric heating systems. But seeking professional advice first is always recommended.With wide double-door sheds, such as this reverse apex shed , you might be losing your mind about how to keep heat in your shed. For doors, the cheapest insulation option is just to keep them closed. You can also use a draught excluder and put up double glazed glass for doors with windows.
