Multi-foils are the most popular of the foil insulation genre, as they are designed to inhibit the condensation difficulties that are inherent in bubble foil and single foil foil products.

However, with a large variety already available, and more of these products coming to market, how do you chose between them? Detailed below, is an outline of the benefits of multi-foil insulation over other types of heat reflecting membranes, plus details of the most popular brands, along with the pros and cons of each product.

Comparative values of each are included ... Click here.

 

Multi layer foil - heat reflecting membrane insulation

Heat reflective foils were created to overcome the problems intrinsic in the use of single foil insulation products which, if used incorrectly, will attract condensation within the structure, resulting in dry-rot in wooden components.

Thermo reflecting foil products are manufactured to different standards, however the one thing they have in common is their ease of installation and space saving potential. Therefore, multi foil insulation is commonly used to replace or complement bulky, old fashioned, dry insulation products.

Multi layer foil insulation is very easily and quickly installed, and dramatically reduces the space that is wasted by traditional insulation products.

 

Why chose multi-foil insulation in favour of single reflective membrane

To obviate potential problems of condensation being created on single thermo reflective foil products, and consequent dry-rot, multi-foil insulation was created.

Soft dry fibre and/or foam insulation is positioned between the various reflective layers of multi-foil insulation, some of which may be waterproof membranes. The resulting multi-foil does not permit extremes of temperature to conduct through the material and cause condensation.

Single thermo reflective foil attracts condensation In temperate climates a single foil insulation, if incorrectly installed, can react in a similar manner to a bathroom mirror when the hot water tap is run. The cool temperature of the mirror, exacerbated by the cold wall behind the mirror, is affected by the temperature change, resulting in condensation. Unlike single foil products, multi-foil insulations act like a double or triple glazed window, which uses the airspace between the glass layers to slow down the transfer of temperature differences from one side of the window to the other, thereby inhibiting condensation and heat loss or gain.

Unlike a mirror that mists due to temperature fluctuations, multi-foil insulation deters the onset of condensation. The soft dry insulation inhibits the creation of condensation caused by dramatic temperature fluctuations, because the dew-point is never reached. They also eliminate the cold bridging problems to which single composite thermo reflective foil products are suggestible.

Details of the Multi-foil insulation concept

Conventional Insulation such as fibreglass, PUR Boards reduce heat transfer by trapping air or gas; they reduce convection as the primary method of reducing heat transfer.

Traditional insulation is not as efficient at reducing radiant heat transfer, which is often the primary mode of heat loss through a building envelope; these products like most building materials have very high radiant transfer rates.
In other words standard forms of insulation are good radiators of heat.

Multi-foil Insulation use layers of Polyethylene coated foils spaced with wadding and closed cell foams, the low emissivity surfaces are very effective in reducing radiant heat transfer ... in fact the metalized foils can reduce radiant heat transfer by as much as 97%

While the internal house temperature may be constant, the outside temperature varies continuously under the effect of climatic conditions (rain, wind, freezing, and snow), solar radiation, and night time radiation evaporation etc.

The behaviour of multi-foils in relation to these conditions is different to that of homogenous, thick insulation products. Multi-foils dynamically combines the four energy transfer modes

Multi foil insulation is built to last

Clearly, all insulation is intended to last for the expected lifetime of a modern building. Regarding the guarantees on foil insulation, we would suggest the period of guarantee relates primarily to the effectiveness of the aluminized layers to continue their job of reflecting infra-red energy. As and when the aluminium tarnishes, it becomes less effective. Therefore, the quality of the lacquer coating on the outside of aluminized foil is vital, while the components of aluminized polyester and the like must be of sufficient quality not to inhibit the reflective qualities of the insulation.

Triso Super 10manufactured in France by Actis Insulation, Tri-Iso is the original multi-foi insulation. The main product certification for Actis Triso Super 10 is issued by BM Trada

Triso Sols also manufactured by Actis, is specifically designed for under floor heating system. Actis Triso Sols has no certification, and has not published any meaningful statistics relating to the performance of this product.

 

Actis – for and against

Actis was the first multi-foil insulation to come to the market, and is commonly associated with multi-foil insulation as a consequence.
Actis is imported from France.
Actis has 19 layers, more than Gen-X, SuperQuilt, and TLX
Actis Triso Super 10 is thinner than Gen-X (33mm) and SuperQuilt (40mm) and the same thickness as TLX Silver.
Actis make claims about their product that have not been scientifically proven by a strict examining body such as the BBA.
Actis certification through BM Trada on April 3, 2009.
Actis may not be accepted by a number of Building Controls throughout the country.
Actis is more expensive than competitor products.

Gen-X – for and against

Gen-X mirrors the Actis and TLX Silver multi-foil concept, but at 33mm is 10% thicker
Gen-X is made in Britain.
Gen-X has less layers that Actis and TLX Silver, but one has to consider what is the benefit of the extra layers?
Gen-X manufacturers, Euroform, have done a great deal of research and development. And, have attained certification from both the BBA and BM Trada, and as such must be accepted by Building Control throughout the UK.
Gen-X is guaranteed for the life equivalent to that of the structure to which it is incorporated
Gen-X costs less than Actis Tri Iso Super 10 or TLX Silver
Gen-X does not require foil backed plasterboard in an under-roof installation, thereby saving in excess of £2.00 per board, excluding VAT
Gen-X's BBA Certificate specifies 75mm of PIR Board as opposed TLX Silver's 70mm.

SuperQuilt – for and against

Shares the same design principles as other Multi-Foil products.
SuperQuilt is manufactured by Yorkshire Building Services (YBS) in the UK
SuperQuilt comprises 15 layers, of which the dry insulation is manufactured from YBS's recycled Non-itch eco-friendly material.
Superquilt is the thickest multi-foil we have available at 40mm
SuperQuilt requires that plasterboard used with this product requires a vapour-check layer
SuperQuilt is certified by BDA Agréments, LABC, Centre for Infrastructure Management (Sheffield Hallam University) and is readily accepted by Building Control.
SuperQuilt is guaranteed for twenty five years ... or the lifetime of the roof.

TLX Silver – for and against

TLX Silver mirrors the Actis multi-foil concept.
TLX Silver is made in Britain.
TLX Silver has nine layers, more than Gen-X but less than SuperQuilt (15) or Actis Super 10.
TLX Silver manufacturers, Web Dynamics, are diffident in their claims about their product, and have invested a great deal in research, development, testing and certification.
TLX Silver holds a current BBA Certification, and as such should be accepted by Building Control throughout the UK.
TLX Silver is guaranteed for 25 years
TLX Silver costs less than Actis Tri Iso Super 10, but more than Gen-X
TLX Silver's BBA Certificate states that polystyrene spaces must be fitted between the multi-foil and the plasterboard ... not a requirement with Gen-X.

Summary

Our view is that there is little discernable difference between the effectiveness of these products, although Gen-X and SuperQuilt are thicker and has better thermal values.

You should not expect to achieve a U-value of 0.20 by utilising a single layer of Actis Triso Super 10, Gen-X, SuperQuilt nor TLX Silver, on their own. (Should you elect to choose Actis, we would recommend that you follow the TLX Silver installation instructions which are the most detailed and accurate).

The strength of Actis's BM Trada Certificate is not comparable to that of a BBA Certificate. And, as such, may not be accepted by Building Control
When the element of a construction is applied in accordance with a valid BBA Certificate, and has the appropriate approvals, it will be acceptable to Building Control departments throughout the UK.
