Doa google on this group on this. Don't bother with it.

And see that it was you that trashed it, based on something you read. As usual.

I regard thin insulation systems as mostly snake oil. They are frequently (mis) sold without stating the precise and demanding installation required for you to stand any chance of meeting their quoted performance.

They rely on being fitted precisely in the middle of two 1" closed air pockets in order to work; it is thin material but not an insulating medium for use in limited spaces. It works mainly by limiting heat transfer by radiation but then claims to "seal roofs against wind and damp, whilst retaining ventilation" without mentioning that where the outer pocket is ventilated the product will perform less effectively since heat will be lost by convection instead of radiation.

IMO, avoid foil based insulation systems, other types (foam based, celotex etc) are more likely to achieve the claimed insulation performance over the life of the property.

From reading the posts here and own research I came to the conclusion that a double sheet of the Daily Mail laid on the ceiling between the rafters would server as well if not better.

Used it on a few roofing contract. Very expensive and from the reports, doesn't live up to spec's

[Doctor Drivel]

I didn't actually test it myself. Boy are some people dumb!!!!

[Doctor Drivel]

It is not approved by the BCO.

[dennis]

It is in some areas... I don't see how it can work as well as claimed. It doesn't trap enough air to insulate properly.

[Doctor Drivel]

It isn't.

It is snake oil.

On the two occasion Vie used it, the method was to lay it over the rafters, counter batten, underlay vapour felt, lath for tiles and tile. The first time I came across it, it was put on the underside of the rafters held in place with staples and plaster boarded over then skimmed. All sites in Nottm

Further to the above:

The UK authorities have pulled the plug on multifoils, when used on their own. The Multifoil Council) made pleaded to the Office of the Deputy Prime Minister when the last round of Part L (energy aspect) of the building regs was being assessed and had a reprieve to 01/01/2007 to give them time to show that multifoils worked as claimed. This repreive has been recinded early because of convincing evidence that the multifoil claims are exagerated. Multifoils will only be permissable if they can pass hot box tests, which they have never have. All the local authorities and the NHBC and such bodies have all been told to no longer accept multifoils.

Action may be taken against the 3rd party certifiers, principally BM Trada, who gave their stamp of approval to Actis and others.

substantiated

In other words, ITS CRAP!! ?

[Doctor Drivel]

Yep - banned. And any gain the stuff has to be fitted "100% correct", which most of it is not.

Where's the above from?

There's a report on the Planning Portal website saying that the values quoted are unsustainable and the Advertising Standards Authority have upheld a complaint against an advert quoting this:

How wonderfully vague.

I only ask because it contains a number of inaccuracies:

1. There is no 'pass' or 'fail' of a hot box test (BS EN ISO

8990:1996); it is a test to determine a properties resistance.

1. Building Control Bodies have not been 'told' to longer accept multifoils. I don't think it's in anyone's power (short of a directive from the Secretary of State) to do so. The LABC (an organisation representing Local Authority Building Control bodies) put out a circular stating their initial misgivings about the TRADA certification of Tri-Iso on which many BCBs had accepted this particular product as having a resistance value of 5.0m^2K/W when it emerged that TRADA had exceeded their UKAS accreditation for doing so. It became my Council's policy for a short while not to accept it or similar products until the situation had been clarified.

2. There is a product, Thinsulex, which has a BBA certificate stating that was tested in accordance with BS EN ISO 8990, which has a resistance value of 1.69m^2K/W. This can be used in several layers or in conjunction with other insulation to give the required U-value. Other similar products, while not having a BBA certificate, are being widely accepted on the same basis.
