BM Trada Certification
Actis Tri Iso Super 10 is a certificated product, replacing Actis Tri Iso Super 9, and has been independently tested by TRADA TECHNOLOGY (TTL) and it carries a BM TRADA Q Mark. TTL recognised the importance of testing products in a live environment. This method demonstrates the performance of a product over time, how it performs in differing external conditions and gives a true representation of thermal performance.
TTL conducted tests on TS9 to assess its compliance with British Standards/Building Regulations, and, following the analysis of the data collected from the field trials, verified that TS9 is equivalent in performance to 200mm of glass wool.
The certification tests were based on comparative tests using two identical cells. Both cells were closely situated together and so experienced the same real external conditions and the same controlled internal conditions. This is set out in the following extract from ...
BM Trada Certificate 0101:
The construction of the test cells, the instruments used on the Actis research and development site for measuring and recording physical values, the trial methodology and rigour of the testing and calibration procedures were considered to be suitable for comparative testing of the Actis roof insulation product TRI-ISO Super 10 and mineral wool insulation.
The methodology has since been reviewed by an independent expert academic at Imperial College London, who has confirmed that, in his view, the methodology used enabled a valid comparative measurement to be taken.
Hot Box Test – BS EN ISO 8990:1996
The hot box test prescribed by BS EN ISO 8990:1996 records the thermal performance of an insulating material in a static controlled environment. Accordingly, the test takes no account of external temperature variances/changes in humidity or the impact that real life conditions such as wind, sun or rain may have on the thermal performance of the material under test.
Actis do not subscribe to this testing methodology but believe that actual in situ performance is a more relevant indicator of real thermal performance.
Actis have installed over 35million square metres of TS9 throughout Europe over the last 24 years. TS9 has an excellent reputation for solving space problems in construction, and from these most challenging of projects TS9 achieves excellent thermal performance.
Actis have continued to test TS9 in a live environment over prolonged winter periods and have found that the fuel usage needed to maintain a constant temperature in a building insulated with TS9 is consistent with the performance of 200mm of
Glass /Mineral wool in a similar environment.
Heat Gain and Loss through a building
The direction of heat transfer is an important consideration in a building. With the potential of Global warming causing more uncertain weather conditions it is important that insulation takes account of Heat gain and Heat loss. Heat is radiated and conducted in all directions, but is convected primarily upward. The figures below show modes of heat loss in houses. In all cases, radiation is the dominant mode.
Methods of Heat Transfer
Heat flows from Hot to cold surface in three ways:-
• Radiation from a warm surface to a cooler surface through an air space
• Conduction through solid or fluid materials
• Convection the physical movement of air
Radiation
Radiation is the transfer of heat (infra-red radiant energy) from a hot surface to a cold surface through air or vacuum, All surfaces including a radiator, ceiling or roof and ordinary insulation radiate to different degrees. Radiant heat is invisible and has no temperature, just energy. When energy strikes another surface, it is absorbed and increases the temperature of that surface.
There are two terms commonly encountered while discussing radiant heat transfer:-
1. Emissivity, the ability of the material surface to emit radiant energy. All materials have emissivities ranging from 0 to 1. The lower the emittance of the material the lower the heat (infra red energy) radiated from its surface. Foils have very low emissivity.
2. Reflectance refers to the fraction of incoming radiant energy that is reflected from the surface. Reflectivity and emissivity are related and a low emittance is indicative of a highly reflective surface.
For example aluminium with an emissivity of 0.03 has a reflectance of .97
Material Surface - Emissivity
Brick - 0.93
Glass - 0.95
Plaster - 0.91
Fibreglass - 0.8-0.9
Aluminium foil - 0.03 -0.05
Conduction
Conduction is the direct flow of heat through a material as a result of physical contact. The transfer of heat by conduction is caused by molecular motion in which molecules transfer their energy to adjoining molecules and increase their temperature
Convection
Convection in buildings is the free transfer of heat caused by the movement of heated air. In a building space, warm air rises and cold air settles to create a convection loop and is termed free convection. Convection can also be caused mechanically. I.e. by a fan or wind
The concept of Multi-foil insulation
Conventional Insulation such as fibreglass, PU 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.
Actis TS9 Insulation uses 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 metallised foils can reduce radiant heat transfer by as much as 97%
How does a thin multi layer foil insulation product such as Tri-Iso Super 10 work?
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 Actis TS9 in relation to these conditions is different to that of homogenous, thick insulation products. Actis TS9 dynamically combines the four energy transfer modes Convection, Conduction, and Thermal Radiation to deliver an excellent real life performance.
What about the research regarding Thin Multi-Reflective Insulation Products?
ACTIS thin multi-reflective foils first appeared on the market in 1981. Since then the technology has evolved technically, their effectiveness have been proven in the market for more than 20 years and the European market size for thin multi-reflective foils grows every year.
The technology used by thin multi-reflective foils (IMTR), which is based on the limitation of the transfers of energy by radiation and convection allows, compared with traditional insulators, to obtain a maximum effectiveness within a minimum space. This alternative solution is particularly important for projects where the space saving is an essential criteria. Also thin multi-reflective foils offer superior performance in the protection against summer heat in constructions.
The technicality of these insulators is not confined with the simple alignment of reflecting films and synthetic wadding. The development of these types of insulator is a synergy defined by the component count, the number of film reflectors, the intrinsic quality of each component and their organisation in the complex structure.
The European laboratories, not having another base of work than that defined by the standards in force tend to use the conventional tools to test the thin multi-reflective foils (IMTR). This step is legitimate and the results obtained with guarded hot box are not called into question. It is the relevance of the results and the extrapolation made which is criticisable. With a non suitable method one obtains non suitable results.
It is not surprising that Test Results in GUARDED HOT BOX are low?
Tests in laboratories, according to conventional methods described by the norms have been conducted for over 20 years! These tests, essentially done with Guarded Hot Box in accordance with the ISO 8990 norm, or Guarded Hot Plates in accordance with NF X 10022 show poor results when testing multi-reflective foils, the results of such tests are of no value when declaring the actual performance of thin multi-reflective foils.
We have conducted these tests ourselves, in our laboratories, using the same tools. In the test environment described by the actual norm, we get the same results crediting the Thin multi-reflective insulation (IMTR) with an R between R=0.6 or R=1.9 whether the insulation product is tested with or without an air cavity.
Actual Norms: what are they? What is their origin ? And are they suitable for thin multi-reflective insulation products?
The reference background setting up the norms and conditions for testing in Laboratories to test materials go back to the 60’s. They are based on:
- The calculation of thermal resistance R of materials, obtained with the measure of the conduction. And, therefore the main elements taken into account are the transfer by conduction.
- Homogeneous materials whereas thermal efficiency is directly linked to thickness and lambda (R = e/I).
- A measure in compulsory stationary flow, even though this suits traditional insulation, it remains far from meeting thermal conditions found in the construction.
These testing methods have brought proof for traditional insulation (thick, homogeneous, internal transfer essentially by conduction and little influenced by thermal stationary state). Nevertheless, they do not seem appropriate when testing thin multi reflective insulation products, which are not homogeneous and use other means of thermal transfer than conduction.
The norm NF EN 75101 listing insulation products susceptible to be tested according to the norms …. No multi-reflective insulation products are mentioned in this document!
Why do we test in a live dynamic environment?
Various objectives have lead us to set up tests In Situ:
- The will to obtain an image closer to reality
- The will to have another method of measuring to reject or confirm the results obtained in laboratories.
The results obtained by measuring thin multi-layer reflective foils In Situ are better than those obtained in laboratories. It is not whether the findings of two different results brings the question to know which one is true, but it is essentially the fact that results In Situ are better than in Laboratories. This last conclusion should not be scientifically possible.
In more detail, a laboratory testing method will tend to obtain optimal characteristics of the tested product. However, when installed in real life conditions its efficiency decreases due to installation constraints. This is actually the case for traditional insulation. This shows that it cannot automatically be assumed that the results will be identical when a testing method designed for a Laboratory is used in an actual construction. This adds to the case that the dynamic test method used to test thin multi-reflective insulation products takes into account more aspects of the building and defines the performance more accurately.
Two different technologies mean two different testing methods
Multi-foils are made of multi-reflective films (low emissivity), synthetic wadding and foams. Their main characteristics, from a thermal point, are to limit heat transfer. Traditional insulation's main characteristic is to limit exchanges by conduction.
Conventional testing methods have been set up to measure the thermal efficiency by thermal conduction. The same method is too often applied to Multi-Reflective insulation products. The efficiency of the results obtained is equivalent to the precautions before hand to make sure that the tool used is appropriate. In short: the results obtained are not symbolic of the true thermal efficiency of Thin Multi-Reflective Insulation Product.
If the Guarded Hot Box method gives information this is between 90% and 100% accurate for a
traditional insulation product. It only gives less than 10% of the information about the conduction of Thin Multi-Reflective Products.
The ACTIS guarantee.
At the present time, in situ measurement is the only tool that gives the characterization of multi-layer thermo reflective insulators objectively possible. The test methodology is the object of many internal and external audits, ensuring the relevance of the results recorded. It is in this context that TRADA TECHNOLOGY LTD has, since 1997 evaluated the means implemented for these tests and certified the results obtained on the cells of In situ tests. Today, in excess of 35 million sq meters have been installed for more than 20 years. Our experience shows that after more than 15 years of use our insulators preserve the quasi totality of their characteristics
