Compare Roof Insulation Products

This page has reviewed the most common questions asked in Insulation as a pass oral. As roof insulation installers, we supply many roof insulation products; however, there are no installations. 

We are not installing certain insulation products because we are not happy to guarantee craft on products that, in our opinion, are not up to scratch. We do not supply blow-in paper insulation or install the same.

To Compare Roof Insulation products, we have compiled a list of the most critical questions we have been asked over the years.

The Importance Of Fire Rating

As we know, Fire Ratings are critical in any home. As a result, the two products with the highest Fire Ratings are Aerolite Insulation and Ecose Insulation. Therefore, Aerolite and Ecose are the only two insulation products certified as safe for Hospitals and Schools.

Insulation products like Isotherm and Cellulose Insulation are combustible and have a BB 1/2 fire rating. Because of this, these particular insulation products have a limited fire rating and are therefore unsafe for Hospitals and Schools. They may not be installed in these buildings.

Roof Insulation That Is Safe For Hospitals and Schools

When we Compare Roof Insulation products, only AA 1/1 insulation can be used in these establishments, confirming the importance of fire rating. However, it is essential to have good quality, safe insulation for roofs.

Condensation

Many homes are affected by moisture and condensation, especially in the Western Cape region, where winters are long and wet. Roll-form insulation products like Isotherm, Aerolite, and Ecose stand out. As roll-form materials, they do not contain paper.

As we know, Cellulose paper will absorb water until the inevitable ceiling collapse. 

Insulation Lifespan

Roof Insulation with a longer lifespan means more extended energy-saving benefits. The longer the lifespan, the better the investment in effective roof insulation. As a result, the energy-saving cost per year improves exponentially the longer the lifespan.

Electrical Wires and Insulation

Wherever possible, all Electrical wires must be above the Insulation. One of the main reasons for this is that most home fires will start with a short electrical wire. As a result, the wire will burn back to the DB box.

However, heat is stored in the insulation where all wires are. As a result, especially BB 1/2 insulation types will burn or smoulder with electrical wire.

Down Light Cones

It is important to remember that downlight cones will eventually melt into the electrical wires. This is because simple downlights build up heat while switched on. As the heat builds up, these cones can melt into the cables.

The image on the right shows how these downlight cones have melted and caught on fire in the roof space.

Water Absorption In Insulation

All our roll for Insulation products do not absorb water. In the event of a roof leak, the water will flow through the Insulation, alerting you to the prospect of a roof leak.

On the other hand, Cellulose Paper insulation absorbs water. If the roof or water pipe continues to leak, the Insulation will eventually become heavy enough to collapse the ceiling. As one can imagine, this is not only costly but can also be a hazard to family and friends.

Will the Wind Affect Your Insulation

Roll-form Insulation, such as Aerolite, Ecose, and Isotherm, will not be affected by the wind in the roof space. The Insulation is cut slightly wider than the beams and pressed down onto the ceiling, creating an excellent tight fit.

However, Cellulose insulation is paper dust like Insulation. We have two large Roof Vacuum machines for removing cellulose, and in most cases, the Insulation has shifted substantially in the roof space. South Easterly facing areas have very little Insulation on one side and more on the opposite end, reducing the Insulation’s effectiveness.
