aerolite ceiling insulation

Ceiling Insulation

All Ceiling Insulation products in South Africa must be SABS tested. These tests are to ensure the Ceiling Insulation products are manufactured to the correct specifications. In years gone by, it was mostly stock market listed companies that manufactured Ceiling Insulation.

In the last few years, everyone is trying a new recipe. Unfortunately, this can end up in disaster for homeowners who are not aware of the problems installing Roof Insulation that will give no benefit or in fact, could be a fire hazard.

Ceiling Insulation Benefits

  1. Saving energy on heating and cooling as a result of more stable home temperature.
  2. Improve indoor temperature by as much as 4-8 degrees in summer and winter.
  3. Some Ceiling Insulation products like Aerolite Insulation have great soundproofing qualities.
  4. Estimates have shown that homes correctly insulated the right ceiling insulation can recover the cost of insulation in as little as three years.
  5. A Healthier living environment as a result of a more stable temperature.

Types of Ceiling Insulation

There are many types of Ceiling Insulation on the market worldwide. This can become quite confusing as some manufacturers have no idea about the risks of making insulation that is not up to spec. All Insulation products must also be tested by TIASA to check for the appropriate fire rating.

Glass Fiber Insulationthink pink ceiling insulation

Glass fiber Ceiling Insulation products are still regarded as one of the best Roof Insulation products available. Because glass fiber products like Aerolite are compression packed making transporting more economical.

Fire rating is one of the main significant factors that separate most insulation products. This is where Aerolite is head and shoulders above the rest. With a Fire Rating, A/A 1/1this insulation will not burn. Aerolite is specified for hospitals because of this unique factor. Most Insulation products for the ceiling space have Fire Ratings B/B 1/2; this means they will not sustain a flame. However, the insulation will merrily burn if there is a flame.

Glass fiber insulation products are mostly used in Europe and the UK. The Aerolite has one of the highest R-values in the country. The Think Pink Aerolite 135mm has an installed R-value 3.78.

Polyester Ceiling Insulation Products

There are several polyester insulation products on the market in SA. However, most of them are not worth a mention. The Isotherm Polyester Ceiling Insulation is one of the best. This insulation is also a SANS complaint on the 145mm Isotherm.

The Isotherm 145mm Insulation is SANS compliant, achieving an R-value 3.76 when installed. This Ceiling Insulation is also SABS approved.

The Isotherm Fire Rating, unfortunately, is B/B 1/2. This insulation will not burn; however, if there is a flame, the insulation will continue to burn with the flame. Polyester insulation products are great to touch and feel; however; the fire rating is a concern to some homeowners.

Cellulose Paper Insulation

Cellulose insulation is the one insulation type that we will not install. Unfortunately, there is no exact science in this type of insulation, in my opinion. The Cellulose insulation is sprayed or pumped into the roof space, and the installer must try and guess what the thickness is by sight. This does not make sense to get the correct depth.

Cellulose insulation also has a B/B 1/2 fire rating. The is an approximate chemical cocktail of about 25%. This has fire retardants as well as chemicals to potentially chasing rats from nesting.

One of the worst problems with this insulation is water. When this type of insulation gets wet, it will absorb the water until the inevitable ceiling collapse. We have a massive vacuum machine for the removal of this insulation product. The last problem is when the product ages it loses its fire retardancy. This becomes a big problem as the paper will now burn or continue to smolder.
