There are many roof insulation products for our homes. However, not all roofing insulation products are equal. Therefore understanding insulation and how insulation works will give homeowners a better idea on how to select the correct roof insulation for their homes. Choosing the best roof insulation is essential. When selecting the right insulation is essential as there are many factors to take into account. A few things to take into account are lifespan of insulation, safety of insulation and health benefits of the given insulation.

Roof Insulation Products

Insulation materials for roofs vary from glass wool to polyester and cellulose paper insulation. Most manufacturers will claim that the insulation products they manufacture are the best. Looking at the various options, we can make an informed decision.

Aerolite Roof Insulation

Aerolite Insulation is a glass wool insulation product that is Eco-friendly and is manufactured to the highest international standards. The Aerolite roof insulation is produced with the new TEL Fiberizing technology for exceptional performance. The World Health Organisation has given aerolite a 111 rating. Making Aerolite safer than most household products found in our kitchens.

The 135mm Aerolite is the premium Aerolite insulation. Furthermore with the AA 1/1 fire rating results in a NON Combustable insulation. For this reason Aerolite Roof Insulation is recomended for hospitals and schools as well as public areas.

Additionally Aerolite is one of the oldest and most installed roof insulation products available.

Polyester Roof Insulation Types

All polyester insulation products from PET PLASTIC pollution. As a result polyester insulation is eco-friendly insulation. However, there are many polyester insulation types available. And most, unfortunately, are not manufactured at a high standard.

Isotherm Roof Insulation

Isotherm insulation is a polyester insulation type. Also, Isotherm is an eco-friendly insulation for roofs. Consequently, Isotherm is dust free and allergy free.

Above all Isotherm is polyester insulation for roofs manufactured from PET plastic bottles. As a result, the ceiling insulation has a BB 1/2. Therefore Isotherm can be installed in domestic homes. However, the Isotherm may not be installed in public areas and Hospitals and Schools.

The 145mm Isotherm is SANS compliant for the Cape Town Region including the entire Western Cape region. The Isotherm Roof Insulation is a great alternative. We are happy to install Isotherm for homeowners; however, we may not fit the insulation in public areas like hospitals schools and shopping centers.

Platinum Fiber Insulation

The insulation is a polyester roof insulation. Also produced from PET plastic bottles. As a result, Platinum fiber is as eco-friendly. The insulation is not entirely up to scratch as the product, unfortunately, does not achieve the correct R-value for the Western Cape and Gauteng. Also, the insulation is a little inconsistent in thickness. For this reason, we do not install Platinum fiber. Fire rating BB 1/2 COMBUSTABLE.

Think Green Polyester Insulation

Think green insulation the name says it all. However, in the test rolls we received, we would most certainly not recommend the insulation. Firstly the insulation is under the specification for most regions. Secondly, the thickness of the insulation is very inconsistent. As we know thickness and R-value are the most critical factor when selecting insulation. As a result, the variable thickness does not make the insulation in our opinion a good insulation option. We do not install Think Green Insulation.

Cellulose Roof Insulation

As insulation installers, we will install all types of effective Roof Insulation products. However, Cellulose is the one insulation material that we will never fit. Cellulose is regarded as eco-friendly however many will dispute this claim. In essence, Cellulose is manufactured from recycled paper like newsprint, etc. However, the 20% chemical cocktail to give the insulation a fire retardent finis as well as the chemicals to reduce the impact of vermin and rats.

Cellulose insulation also has a BB 1/2 FIRE RATING. Therefore cellulose is combustible. The fire retardants dissipate leaving cellulose flammable.

As we know cellulose is pumped into the roof space. The first problem with the blown insulation application is that there is no exact thickness preferably a guess as to what the depth maybe. Additionally, the paper insulation absorbs water in the event of a roof leak. In most cases, the water leak will end in a ceiling collapse. In fact because of the demand to have cellulose insulation removed because of health issues or water damage as a result of cellulose absorbing water. We now have the only three roof vacuum machines available for the removal of the cellulose.
