What is Spray Foam Insulation made of?

how much insulation do i need
 

Spray foam insulation is the most modern method of insulating property on the market and is significantly more effective than other products.

But what is Icynene spray foam insulation made of, and what do the components combine to provide?

Let’s explore this question in greater detail…

What’s Spray Foam Composed Of?

Icynene’s full name is Icynene LD-C-50, which refers to its full chemical compound. It is a water-blown, open-cell industrial foam. The foam is created by mixing equal amounts of two ingredients: Methylene Diphenyl Diisocyanate (MDI), and water.

Methylene Diphenyl Diisocyanate (MDI) is a chemical used to produce polyurethane (plastic) type products, one of a family of chemicals used in everyday plastics.

Polyurethanes are created by mixing Diisocyanate chemicals (such as Methylene Diphenyl Diisocyanate, used in Icynene) with each other or other compounds.

Methylene Diphenyl Diisocyanate is used in other products you’ll have around the house; such as elastics, sealants, adhesives and coating. It is non-toxic and non-harmful.

The Diisocyanate chemical family is highly reactive with water, and so by combining the two at installation, Icynene spray foam is created.

It is either injected, or sprayed, directly into the relevant area or cavity, and as it’s mixed, it becomes an impressively expansive foam, expanding up to 100 times its original size upon application.

It dries over a 24-hour period once installed, but the chemicals only react for around half an hour.

Neither Methylene Diphenyl Diisocyanate, nor water, smell, but those with extremely sensitive palates may notice a light odour of amine catalysts.

These are completely harmless chemicals naturally occurring in all forms of spray foam, but only detectable by those with an acute sense of smell.

Even after fresh installation, the most keen of noses shouldn’t be able to smell any amine catalysts after a couple of days.

This all said, the seal that spray foam insulation creates will keep in any existing smells from within the house, so anything of a particularly strong odour may need to be removed, prior to installation.

But What About Other Products?

In some products, the ratio of chemical to water could affect its output. The specialist equipment used by Icynene technicians cuts out if the 50-50 ratio is imbalanced, meaning there’s no chance of an ‘off’ chemical ratio.

In turn, spray foam insulation technicians insulation technicians are fully accredited by the BBA (British Board of Agrement) and offer a 25-year product guarantee. But don’t take out word for it – read up on other customers’ TrustPilot reviews!

Insulation made with Methylene Diphenyl Diisocyanate has been proven to maintain temperature more efficiently than any other product thus far.

Formaldehyde is present in all insulation products but more so in older, more traditional materials. It is naturally present in spray foam insulation but third party chemical tests have shown that even in freshly installed foam, but only in ‘trace’ portions – so well below the guidelines for safe amounts allowed.

Toluene Diisocyanate (TDI) is used in other insulation products, but is not present in spray foam insulation at all; neither as an addition nor a naturally-occurring substance.

Is Spray Foam Insulation Safe?

Once spray foam insulation has been installed, there is a 24-hour period in which, dependent on the installation, the technician may recommend you vacate the property.

After this 24-hour period, the chemical ‘off-gassing’ that may occur (ie. any gases or chemicals that may be absorbed into the air from the spray foam insulation), is of negligible amounts, and would not be harmful to your health, or compromise indoor air quality.

Spray foam insulation is by far the safest insulation material on the market; it’s unique chemical make-up ensures that it functions effectively, year on year.

It allows sufficient thermal flow for temperature regulation (conduction, convection and radiation)-fantastic features which make it the market leading product  Combined with the sealant properties it has for even the smallest and strangest shaped nooks and crannies, Icynene spray foam solution is easily the most efficient on the market.
