How Does Low-E Insulation Work?

Low-E Insulation stops heat, deadens sound and won’t absorb moisture.

The unique design of Low-E Insulation allows it to resist all 3 forms of heat loss and provide maximum thermal performance while also resisting moisture absorption, stopping draughts and uncontrolled air movement, and deadening sound.

Low-E is a very simple, very effective insulation material. It just so happens that is it also easy to work with, made from recycled material, safe to handle, has no airborne fibers to worry about, is class 1 fire rated and can be used virtually anywhere!

Three Types of Heat Loss

The composition of Low-E Insulation means that it can successfully tackle all three forms of heat loss. Low-E Insulation is made from pure aluminium which reflects 97% of radiant heat away from the surface and back to the heat source, while our recycled closed cell foam provides a thermal break to reduce and stop conduction and convection.

Emissivity

Low-E Insulation is manufactured using 99.4% Pure “Insulation Grade” Aluminium which reflect 97% radiant heat. This has a massive impact on heat transfer into and out of a building.

Airspaces and R-values

Foil insulation products can work without an airspace but to declare what is called an “R-value”, you must install foil insulation with an airspace. Airspaces can be forms in numerous ways and can be as small as a couple of millimetres but airspaces beside a low emissivity surface are most efficient between 6mm – 20mm.

The Pure Aluminium surface of Low-E surface reflects heat into an airspace and the airspace becomes VERY efficient. Now you have an insulation system that can reflect all 3 forms of heat loss. We recommend installing Low-E Insulation with 2 airspaces whenever possible. Because Low-E utilises airspaces, the R-value for Low-E Insulation actually changes depending on the size of the airspace and the direction it is facing (horizontal or vertical). Contact our technical team to easily calculate the R-value of Low-E Insulation in any application.

Moisture Control

Low-E Insulation ’EZY’ Seal is a complete vapour control layer (VCL). It can be used to the internal side of a building envelope or structure. Team Low-E Insulation with any secondary insulation and protect it from moisture absorption, extending the life of your insulation system. Low-E ’EZY’ Seal Insulation has been tested (BS EN 3177) and shown to have an MVTR rate of >2000 MN s/g

Low-E Insulation PERF is a breathable reflective insulation. It has been designed to allow vapour transmission to pass through the material. It is ideally suited for use on the external side of an insulation system or in refurbishment projects, where it is necessary to maintain breathability. Low-E Insulation PERF has been tested to BS 3177 and shown to have an MVTR rate of 0.11 MN s/g making it suitable for use in both roof and wall systems.

Air Tightness

Low-E Insulation eliminates draughts and uncontrolled air movement has. The pure aluminium foil is a completely airtight but foil on its own is not enough. Own closed cell foam provides a separating layer between the layers of foil and it is also airtight.

Why use an infiltration barrier that offers no thermal performance? Install Low-E Insulation in one labour step and gain a boost in thermal performance as well as addressing airtightness. Low-E Insulation was independently tested by the BBA (BS EN 12114) and shown to have ZERO Air-Leakage @ 600 Pa (m³ hr m)

Low-E Insulation can be installed on its own or teamed with a secondary insulation to meet higher R-value standards. It is not meant to replace ALL the insulations on the market.

Low-E Insulation is designed to increase thermal performance and airtightness, reduce condensation risks and life-cycle running costs, and most importantly, to tackle issues which have been previously unaddressed by bulkier traditional insulation products.
