How Do You Buy Foam Insulation?

Foam insulation come in a variety of forms including but not limited to; foam insulation board, foam insulation sheets, foam insulation kits and spray foam installed by professionals.

We sell Icynene which does not come in sheets, boards or kits. We apply the foam directly from our purpose built vans and equipped to create complete air seals in a property, insulating them to the highest standard. As official Icynene dealers we are certified and trained to install the product.

Icynene IS NOT sold in the form of foam insulation kits. Certain aspects of installation including foam insulation R-Value, thickness and safety precautions have to be taken which makes it an unsuitable activity for the average DIY builder to partake in.

If you are not sure if your property is suitable, please do not hesitate to contact a member of our team and we will happily advise you on our services.

Open cell insulation is more suited towards residential properties because of its vapour permeable structure. This means it allows indoor air pollutants to dissipate through the roof. Indoor air pollutants can come in many forms ranging from cigarette smoke to the gas offset by appliances, such as cookers

Open VS Closed Cell Foam Insulation

Open and closed cell insulation both have very different application purposes, with open cell foam more suited to residential properties and closed cell foam insulation more suited towards commercial.

Open cell insulation is more suited towards residential properties because of its vapour permeable structure. This means it allows indoor air pollutants to dissipate through the roof. Indoor air pollutants can come in many forms ranging from cigarette smoke to the gas offset by appliances such as cookers.

Open cell insulation can also be cut into if any amends or upgrades need to be made yo your home, however keep in mind if you cut into the foam it will affect how insulated your house is.

It also allows steam from showers to escape through the roof helping prevent against mold and condensation damage.

Closed cell foam is a more dense product. It’s good for securing tiles and roofs that are beyond the point of repair, this is why we recommend it for commercial properties.

It is also able to reject bulk water from heavy rain or flooding but will not dissipate water as open cell foam insulation does.

Foam Insulation vs Fibreglass

Foam insulation is a completely different product to fibreglass, so when people ask how ‘foam insulation vs fibreglass’ compares, you can see foam insulation is a superior in quality, performance and durability. Some of the issues you have with fibreglass that you do not get with foam include:

  • Fibreglass is an irritant – Fibreglass can cause irritation as respiratory problems, especially when handled without protective clothing.
  • Nesting point – Fibreglass acts as an ideal nesting point for rats and rodents. On previous jobs where we have removed fibreglass it is not uncommon to see animal waste and deterioration of insulation caused by rodents eating at materials.
  • Deterioration of product- Fibreglass loses its insular quality after years and has to be constantly topped up, using up time and effort. Once Icynene foam insulation has settled it will not degrade over time, lasting a lifetime.

Insulation R-Values: Why They Matter
