All rolls are 1.25m wide and are available in 5m² rolls (4m in length), 10m² (8m in length), 20m² (16m in length) and 40m² (32m in length).

  • Nominal thickness – 5.5mm +/- 10% – Giving possibility of leaving air gap for even greater efficiency or utilising some of the otherwise wasted cavity space for additional storage. 

Why is Low-E perfect for insulating your van?

Low-E is produced from non-toxic Closed Cell Polyethylene Foam which is heat laminated, using a patented production method, between two surfaces of 99.4% pure aluminium facings. You will see many other foil insulations in the market but none of them are as easy to use and will do as much for you for your money.

What makes Low-E a truly space age product is that the large lightweight rolls, made from recycled material allow for easy installation. Low-E Insulation has the ability to resists all three types of heat transfer while providing a full vapour barrier, with sound deadening properties that also has a Class A/ Class 1 Fire Rating.

The technical stuff – What should I know?

Before we talk about Low-E Insulation we need to define three thermal values. The first being‘R’, the second being ‘U’ and the third being ‘E’.

U-values are a measure of a materials ability to conduct heat. The thermal performance of windows and doors is commonly stated in U-values. U-value is equal to 1/R (R-value).

R-values are the inverse of U-values: the resistance to heat flow. Low-E insulation products do have an R-value but the reason they work so well is in the name.

E-values or the ‘E’ in Low-E stands for Emissivity. Emissivity is the ability of a surface to emit or transfer radiant energy through itself – everything has an E-value.

Convection is a warm air current, you can see convective heat from a hairdryer or from the surface of hot road

Conduction is when heat travels between two touching objects or through one solid object.

Radiation: Radiant heat is electromagnetic waves which can pass through anything.

“Radiation is the primary mode of all heat transfer. The other two modes… come into play only as they interfere with the primary mode.”

Energy Design Update, Feb. 93. Stated by C.M. Pelanne, Senior Research Specialist for Johns Manville

Why Aluminium?

Everything has an emissivity value, your clothes, a table. For example cast iron has an Emissivity of .85 This mean that 85% of heat that comes in contact with its surface to pass through it, which is why we make radiators from cast iron.

Aluminum has a natural low emissivity value of .03. This means that aluminium will only allow 3% of radiant heat that comes in contact with its surface to pass through it, the rest will be reflected back to the source. You’ve all heard about Low-E glass in windows. They work by the same principle, they have a Low Emissivity Coating on them which reflects radiant heat back to the source.

Here are the Emissivity values of some typical building materials:

Asphalt:  .90-.98  | Brick:  .93 | Plaster:  .91 | Concrete:  .85-.95 | Wood:  .90 | Glass:  .95 | Fiberglass/cellulose:  .80- .90+

Pure Aluminium Foil:  .03- .05

Low-E, because it is made from pure aluminium, has an e-value of 0.03 which means 3% of radiant energy that comes in contact with its surface will pass through it.  Or another way to look at it is that Low-E will reflect 97% of radiant energy that comes in contact with it.

“If a surface emittance is changed from .90 to .03 the part of the heat flow that is radiation is reduced to 3.3% of its initial value.”

If you remember that conduction only accounts for up to 7% of heat transfer. Maybe we should ask the question.
“ Why do we put so much importance on ‘U’ & ‘R’ values”??

Regardless of how high the R value on an insulation product is, unless it also has a low – E value  it has no ability to reflect radiant energy and will always need to absorb the heat in order to work. Very high R values don’t stop heat transfer, they simply slow it down.  You cannot ignore the need for good U values, but by addressing the U values alone a large percentage of heat transfer is being ignored.

For optimum thermal performance, you need an insulation product with a high R value but also a low E value.
The primary function of Low-E Insulation is to reduce the transfer of radiant heat.
Low-E, because it is made from pure aluminium, has an e-value of 0.03 which means 3% of radiant energy that comes in contact with its surface will pass through it.  Or another way to look at it is that Low-E will reflect 97% of radiant energy that comes in contact with it.

Low Carbon Footprint

Low-E’s low Carbon Footprint is due in no small part to their patented production method which completely eliminates the use of glues, adhesives or solvents. A current project running at the University of Salford’s state-of-the-art Energy House will show real life Carbon Savings involved with fitting Low-E. We are very confident that Low-E will prove itself as the first Carbon Negative Insulation product.

Low-E Insulation has one of the lowest Carbon Footprints (or GWP Global Warming Potential) of any Insulation product of sale today in the UK. To carry out this complicated assessment Low-E acquired the assistance of C-Tech innovations [an independent third party]. To do this C-Tech used the recognised CCalC (Carbon Calculations over the Life Cycle) tool.

The equation for product carbon foot printing is the sum of all materials, energy and waste across all activities in a product’s life cycle by their emission factors. The calculation in this instance involves dividing the activity data associated with the production of one roll of insulation to give CO² per unit (roll).
