Is Apollo’s range of HRM accepted by Building Control?

Yes.  Thermo-Foil®ES and Eco-Brite® are BBA (British Board of Agrément) certified products and are the only Low Emissivity Heat Reflecting Membranes of their type currently available.  We also hold certification from Denmark, Singapore, and Dubai, please see our certification section.

Does Thermo-Foil®ES and Eco-Brite®need to be used with additional insulation?

Yes.  Our HRM will reflect back 95% of radiant heat hitting its surface, used in conjunction with conventional insulation our HRM will enhance the insulation properties, and could lead to a reduction in soft insulation required, whilst providing a lower U-Value.   Apollo's HRM also act as an excellent vapour barrier, halting moisture migration into the buildings other insulation layers.  The systems ensure soft insulation layers are kept dry.   In certain climates, if other insulations are not used condensation will occur on the cold side of the foil.  The use of other insulations moves the dew point away from the foil.  (Dew Point is the point at which water vapour condenses on a cold surface.) 

 Can Apollo's HRM systems be used in floors, walls and roofs?

Yes, our product ranges improves U-Values throughout the structure, walls, floors and ceilings, and even your heating or ventilation system.

Why is Apollo's HRM better that a multi foil product?

Multi foil products will only reflect on the external faces of the foil.  The internal faces that have other insulations between the foils act only as a standard insulator as heat passes through by conduction between materials.   It should be noted that you can only radiate heat through an air space or a vacuum. 

Can Apollo's HRMs be used as a vapour barrier?

Yes, it acts as an excellent vapour barrier ensuring soft insulation is kept dry.  They may be used to restrict the ingress of landfill gases and airborne radon into a building.  They are rodent resistant and suitable for use in agricultural buildings. Apollo's membranes in some cases are 500% better than polyethylene, as a vapour barrier.   This is due to the inclusion of high grade no pin holing aluminium in most of our laminations.  Thermo-Foil® ES, EncaSeal™ and EncaClad™ have a vapour transmission rate of 0.021g/m², Eco-Brite® has a vapour transmission rate of 0.023g/m²

 What energy efficiency can I expect to see if I use Apollo's HRM?

Depending on your structure if you stop air infiltration and control the internal environment of you building you can save as much as 25% on your heating costs and 30% on you cooling costs.   This does depend on the age and quality of your building.

What is a U-value?

A U-value is a measure of thermal transmittance – i.e. how much heat is lost or gained through a structure. It is the inverse of the sum of the R-values of the components and the lower the U-value the better.

What is a Lambda value (λ)?

A Lambda value demonstrates the thermal conductivity of a material. The lower the Lambda value the better.

What is an R-value?

An R-value is a measure of the thermal resistance of a material – the higher the R-value the better.

What is emissivity?

Emissivity is a measure of the reflectivity of a surface to infra red radiation. The lower this measurement is the better.

What is the emissivity of Apollo Membranes?

The emissivity of our product we give our standard measurement of 0.05, under our test certification the figure is 0.047.
