AIRFLEX REFLECTIVE INSULATION With the new generation of ultra-thin reflective insulating product called Airflex, a new era in home comfort begins. Ultra-Thin but Ultra Insulating, Really Non-Flammable, Totally Impermeable, Environmentally Friendly

Specific Benefits Provides Extra Living Space - Only 10mm Thick Easy to Install - Light & Flexible Requires Little Storage Space - Gain Transport Space Economical - Helps save Energy and Money Warranty - Comes with a 10-year Manufacturer's Warranty

Airflex - Roof Insulation Airflex can be installed horizontally or vertically according to guidelines. It is advisable to staple Airflex to rafters to hold in place prior to fixing battens. Then it can be used as sarking and underslaters felt as well as insulation. Building Regulations and Roof Ventilation Standards should be adhered at all times. All joints between panels should be covered with Airlfex Reflective Ahdesive Tape, other brands cannot be guaranteed to be effective.

The Ultra-Thin and Ultra-Performing Refelctive Insulation


Airflex - Under Roof Frame Insulation Airflex can be used as Under Roof Frame Insulation on different applications such as: - Under metal beams - With an existing roof boarding underslaters felt - With no existing roof boarding underslaters felt - Under rafters, tiles, slates, thatch roofing, plasterboard or wood panel finish - Under rafters with Angled T-Hangers - On plasterboard and exposed rafters - With close boarded on rafters - Under rafters with a sound absorbing medium for places with very high noise pollution levels All Installation methods must adhere to local standards	Airflex - Wall Insulation Good insulation needs goods ventilation in order to prevent condensation problems. Houses or buildings must be ventilated - with fresh air inlets in the exterior walls/joinery of dry rooms - with a CMV (Contolled Mechanical Ventilation) in damp rooms - with air bricks in the indoor finishing material once Airflex is installed. To prevent any closed cup or insulating bottle effect, it is very important to air the rooms. All joints between panels should be covered in Airflex Reflective Adhesive tape.	`Airflex - Under Floor Insulation Since Airflex resists compression it can be installed under different types of floors, such as cement screed, concrete slabs or wood floor. Full details on the Advantages, Technical Characteristics, Benefits, Applications and Installation can be obtained upon request.`

U-value Combined Method: 0.16Wm²K
(lower limit - 56.306²K/W)
(Correction for mechanical fasteners, Delta Uf = 0.000W/m²K)
(Correction for air gaps, Delta Ug = 0.000W/m²K)

Watt: a unit expressing the energy (of heat) flow or loss or consumption per one second

Celsius: a unit expressing the temperature. Some times expressed in ºK (Kelvin) Temperature in ºK is equal 273 + temperature in ºC

Guarded Hot Box: test procedure used to measure heat flow through a non homogeneous building section and governed by ASTM (American Standard Test Method).
The size of the measured sample is about 2m².

Guarded Hot Plate: test procedure used to measure heat flow through a homogeneous material (not a building section). The test device is smaller than the guarded hot box. The size of the measured sample is about 20cm x 20cm.

Thermal Conductivity: ? value expressed in W/m.°C

A unit expressing heat transfer by conduction through a material (liquid, solid, gas)

The energy loss through the material is:
? = (T1-T2) ? S/e Where S is the surface and e the thickness.

For a given thickness and surface and for a given temperature T1 and T2 at the surface of the insulation, the lower the ? value, the better the insulating property of the material.

Air: ? = 0.026 W/m. °C
AIRFLEX: ? = 0.362 W/m. °C
Water: ? = 0.600 W/m. °C
Aluminium ? = 230 W/m. °C

R value:
A unit expressing the thermal resistance of a material.
R value is expressed in m.°C/W
R value = e/ ? where e represents the thickness.

For a given thickness, lower is the conductivity, better is the insulating property, higher is the Thermal Resistance.

U-Value: a unit expressing heat transfer through a complete building section, including Air films. The lower the U-Value the better the insulating value of the building section.
U_Value is expressed W/m².°C
(Watt by (Square meter x Celsius)).

Thermal Bridge: part of the structure of lower Thermal Resistance that bridges adjacent parts of a higher Thermal Resistance.
Thermal Bridges can result in localised cold surfaces on which condensation and mould growth can occur.

Radiation: Radiation is the transfer of Heat or Energy from a hot surface to a cold surface through air or vacuum.
The radiant heat called infra-red heat rays, is invisible and has no temperature, just energy.

Emissivity: from zero to one, refers to the ability of a surface to emit radiant energy. Lower if the emissivity, better is the ability of the material to reflect the energy or the heat.

Reflectivity: refers to the fraction of incoming radiant energy that is reflected from a surface. For example, aluminium with an emissivity of 0.05 has a reflectivity of 0.95.
Reflectivity polyester has an emissivity of 0.6.
Wood or brick have an emissivity of 0.93, means they are more absorbing the radiant energy than reflecting it.

Convection: is the transfer of heat in fluid, such as air, caused by the movement of the heated air or fluid.
The passage of heat from a source of energy (radiator for example) to its environment occurs partly by radiation and partly by free convection of the surrounding air.

Mass Insulation: (fibreglass or foam board).
Mass insulation slows the heat transfer by conduction. These materials also reduce the heat transfer due to the presence of trapped air.
Mass insulation is not as effective against infra-red radiation, actually absorbing it rather than reflecting or blocking it.

Reflective Insulation System: typically formed by low emissivity material and adjacent air spaces (in front and behind).
The performance of the system is determined by the emissivity of the material, the thickness of the material and the size of the adjacent air spaces.
The optimal thickness of the air spaces is between 20 and 30mm.

The U-value of the systems takes into account the R value of the reflective material and the R Value of the two air gaps.

Key Thermal difference between Reflective Insulation System and Mass Insulation:
Reflective insulation has no significant mass to absorb and retain heat.
The change in thermal performance due to compaction or moisture absorption, a common concern with fibreglass insulation, is not an issue.
Reflective Insulation has a very low emissivity value and this significantly reduces heat transfer by radiation.

Insulation
Airflex is a semi rigid compound with a total nominal thickness of 10mm. The components are welded together on each end and down the centre of the panel to form a semi rigid sheath with excellent thermodynamic properties.

With its 10mm thickness and pure aluminium surface. Airflex is the ideal insulation for your home.

When Airflex is combined with 120mm of glass fibre wool, it achieves a U-Value of 0.20 providing a comfortable living condition for your home.

Certification-
Airflex is now certified by LABC Building Control and BBA. This is one of the few multi foil insulations that are approved by these two major building controls.

The Facts:
Airflex has been independently assessed by Sheffield Hallam University in a comparative test using 200mm of Glass Wool. The test results showed that Airflex was 44% MORE efficient than 200mm of Glass Wool.
Using these results we can achieve a 1.5 U Value with out other insulations combined.

However, BBA. LABC, IAB, CSTB and other major organisations do not accept this method of testing.

What they do accept however is if Multi Foils are tested with another insulation combined.
Airflex has been tested using additional insulation and is now accepted by LABC & BBA.

The most effective and cost efficient way to achieve a 0.2 U Value and ideal comfort and insulation for your home is by following the proper guide lines and is to use one of the systems below.

Airflex + 70mm PUR
Airflex + 120mm Glass Wool
Airflex + 90mm Platinum Warmsqueez
Airflex + 110mm Warmsqueez

These systems conforms with building regulations and are accepted by Building Control.

Efficient, safe, reliable; all the Reflective Thermal Barriers guarantees are concentrated in Airflex. Its performance corresponds to what specialists are looking for: a non-flammable, impermeable, healthy, environmentally friendly product with high reflecting power.

Its lifetime is almost infinite and its reflecting power remains constant over the time under standard installation conditions.
