Loft Conversions & Timber Frame Buildings - The Benefits of Multi-Foil Insulation Explained

What are the advantages of using multi-foil insulation and how can you benefit?


If you decide to use multi-foil thermal insulation when carrying out a loft conversion, compared to the more traditional materials on the market, multi-foils can easily reduce insulation thickness and save space inside the building. This would be of the upmost importance, for example in loft conversions where you would hope to maintain head room.


By applying a multi-foil thermal insulation that has been specifically designed for loft conversions, head room in the interior of the structure will have been slightly increased, and the work to be carried out will have been cut back to 3 easy operations. As a matter of fact, if you then decided to implement an insulated plasterboard with the plasterboard and foam already bonded it would reduce this task to just 2 easy operations. Nasty time consuming tasks for instance battening the rafters, installing glass wool which needs a protective mask, or having to cut boards for the gaps between the rafters are no longer necessary. The findings of an independent assessment by a chartered quantity surveyor advocate the multi-foil option might provide a 30 percent cutback of hours spent on labour in comparison to the decision to use polyurethane boards.


When considering timber frame constructions, the multi-foil is fitted inside the timber studs, then, plaster boarded & battened thus providing you with a vapour barrier, as well as an air space and cavity to enable completion of services. Glass wool or rigid board is fixed in between studs, giving you the required U value.


The benefits are, timber stud sizes can be reduced and the required U value is still achieved. Alternatively, stud size can be maintained but even lower U values achieved.


This exceptional product, the breathable multi-foil, includes multi-foil insulation and a tile under-lay, and is installed above existing insulation, by way of example when upgrading or renovating a roof, with no condensation risk. Multi-foil insulation materials, which have been through standard method testing by UKAS accredited bodies in the UK, have a role to play in both new build and refurbishment projects. Producers are creating unique multi-foil insulation items that are likely to play an increasing role as demands for multi-foil thermal insulation efficiency rise.
