How Low-E Insulation Is Made

Low-E Insulation is manufactured using a patented production method that eliminates the use of glues, adhesives and solvents. Our recycled, non-toxic, closed cell foam core is heat bonded to our 99.4% Pure Insulation Grade Aluminium. Not alone is the process patented but so is the product itself.

Glues and adhesives can break down over time especially when exposed to hot and cold as often as insulation is. Glues and adhesives can also contribute to the spread of fire. It is important to us to make sure our products are as safe as possible.

Foil insulation is a simple idea; use pure aluminium to reflect heat back to the heat source. It would be easy to do that with a single layer of aluminium; the problem is that single-layered products create problems as well as solving them. So they obviously answer is to add an additional layer to reduce the risk of condensation forming on the product.

Superior Performance

Architects and designers love specifying Low-E Insulation to maximise the designed useable space. Low-E is quick clean and easy to install. It has no fibres and is indoor air quality approved

  • Resists 3 Form of Heat Loss – Reflects 97% Radiant Heat
  • Stops draughts – Won’t absorb Moisture
  • Non Toxic – Mould and Fungi Resistant
  • Saves Space, Install time, Labour Costs
  • Class 1 Fire Rated – Deadens Sound

Insulation system, better than one insulation in its own Low-E has sound deadening qualities similar to mass insulation. Low-E is nontoxic. There are no fibres to stick in your skin or get in your eyes and there are no carcinogens to inhale. Unlike some insulations on the market Low-E doesn’t off gas over time and negatively affect indoor air quality.

There is absolutely no safety equipment required to handle or install Low-E. It is very light and with over 45m2 in a roll it Low-E will save time, space and money. Its unique core design means that Low-E will not sag after installation, drag on screws or fray after cutting.


Low-E -v- ‘Multi’ Foil

Foil insulation is a simple idea; use pure aluminium to reflect heat back to the heat source.

So why do so many companies get it wrong?

You can reflect heat with a single layer of aluminium, that’s easy! The problem is, when hot and a cold meet on a single layer product it creates an increased risk of condensation. So, the obvious answer is to add an additional layer to reduce the risk.

Different company have tried to do this a number of different ways using various different materials. The problem is that these other products also tend to create additional problems.

  • They use bubble wraps or single layered products; which don’t stop condensation
  • They glue the products together, and the glues break down
  • They use fibrous cores; which absorb moisture
  • They use Mylar instead of Aluminium cheap

See Aluminium -v- Mylar →

Multi-Foil Insulations came out in Europe back in the 1990’s. They usually consist of multiple layers of mylar and have fibrous cores made of wadding (cotton, polyester, plastics). They tend to have poor fire ratings or no fire testing, which means they cannot be used in wide range of applications.

They are bulky and require longer screws and fixings. Their multiple layers make them difficult to cut and work with, they tend to catch on screws making them very labour intensive to install.

A lot of ‘Multi’ Foil Insulation companies recommend their products can be installed 20mm or 25mm battens. The problem is that ‘Multi’ Foil products can be anything from 35mm up to 80mm thick. They fail to explain is that to create a 20mm airspace with a 35mm product you would actually need a 47mm batten.

Low-E is not a multi-foil insulation and it does not have any of these multi-foil drawbacks!!

Aluminium -v- Mylar

Only aluminium has a natural low emissivity value. Mylar, while it does look ‘shiny’ and might be good at reflecting light, does not reflect heat in the same way as aluminium.

Mylar is much cheaper to produce but usually delaminates, cracks, chips and peels especially when it is exposed to heat and cold as often as insulation is. It might be good at keeping food fresh (packets of crisps and kit-kats) but not something you want from an insulation material.

Multi-foil insulations are not used or found in countries where regulations and foil insulation is widely understood. In the USA foil insulation has been used for over 30 years but multi-foil insulation is still not sold there due to its lack of compliance and failure to meet basic Fire Safety Standards.


Low-E -v- Traditional Insulation

For years people have been convinced that to insulate better, they should add more and more traditional insulation. The thicker the insulation, the better it works! But that doesn’t really solve the problem. Why?

Heat Transfer

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.

To explain why this doesn’t work, I am going to describe an extreme scenario. Imagine a shipping container sitting the desert. The sun is heating the steel box and the temperature inside the box rises. Now image the shipping container is insulated with traditional insulation. The sun starts to heat up the box but the temperature inside doesn’t start to rise straight away. However, once the insulation has absorbed the heat from outside it starts to re-radiate that heat into the box. Eventually, the box starts to heat up, it is inevitable! So how do we solve the problem?

Fitting and Installation

Did you know, traditional insulations can be very difficult to fit “properly” and may not achieve its designed performance? If 100mm fibrous insulation is installed and compressed to 90mm, or overstretched to 110mm, it will never actually achieve its designed performance.

This is why the reflective insulation manufacturers of Europe have been pushing for in-situ testing for all insulation materials. There is no point in insulations meeting a standard in a laboratory if they do not achieve it in the real world

Air Quality

Traditional insulations can also have a negative effect on indoor air quality due to airborne fibres that can stick to your skin or get in your eyes. Some are even classed as carcinogens and are produced using toxic blowing agents. Did you know that most foam insulation products ‘off’ gases and are so toxic, they can never be recycled, incinerated or put into landfill.

Moisture Control

The other problem faced by traditional insulation is that heat and warm air also carries moisture. When the warm air cools the moisture gets left behind, it is then usually absorbed by the insulation. Once the insulation absorbs moisture it tends to compress and it loses the ability to insulate. You may have seen this if you have ever been up in an old loft and noticed the old insulation is compressed and discoloured. Foam insulation doesn’t have the same problem with moisture absorption because it is usually made from a chemical compound.

Environmental Benefits

Low-E is manufactured from non-toxic, recycled closed cell polyethylene foam. Up to 40% of our foam core is actually manufactured from recycled milk cartons. Not only does this reduce the need for refining and processing raw materials, it makes use of a product that is used every day and save it from a landfill. Low-E Insulation has one of the lowest carbon footprints of any insulation material on sale today

Global Warming Potential

Most insulation materials can make claims of low carbon footprint or Global Warming Potential (GWP) since they insulate and reduce CO2. Low-E Insulation has one of the lowest Carbon Footprints or GWP of any Insulation product of sale today, even without considering the carbon saving from life-cycle use. This is due in no small part to our patented production method which eliminates the use of glues, adhesives or solvents.

Reducing Energy Consumption

Low-E Insulation tackles all 3 forms of heat loss, provides moisture control and reduces draughts and air leakage. It is one of the most efficient Insulations on the market. Using Low-E is guaranteed to reduce energy bills and life cycle costs.

Transport and Storage

Low-E doesn’t just save space as a product. Our large compact rolls also require less packaging and take up less space in transport and storage. This has a hugely beneficial impact on the environment, as well as being more economical.

Space Saving

Incorporating Low-E Insulation in any insulation system means the profile of the system can be made smaller/narrower. This also reduces the thickness of ancillary components. Steels, timbers, secondary insulation, nails, screws or other fixings. Reducing ancillary components reduces haulage takes and takes trucks off the road. It also has the adding benefit of reducing internal/occupied space and reducing overall costs.

Carbon Negative Product

Once the life cycle saving CO2 saving of Low-E Insulation are taken into consideration Low-E actually has a Carbon Negative Footprint. The carbon footprint of Low-E Insulation was independently tracked by C-Tech Innovation. From raw materials, through production and even through to transportation and delivery. The below findings are calculated by C-Tech Innovations using the recognised CCalC (Carbon Calculations over the Life Cycle) tool.
