Loft Room Insulation

Loft Room Insulation is a specialised field of Roof Insulation. In the application of insulation to loft room Areas we prefer Insulating with the Isotherm 145mm Insulation.

We would wire the Ceiling Insulation to the side of the ceiling to keep this in place. The Isotherm is a better fit because the Isotherm has a 30 year guarantee so the fibres will not collapse and the insulation will last longer than most buildings.

Insulated loft rooms are far warmer in winter and the heat is reduced by up to 80%.  Loft rooms are know to be unbearably hot in summer in uninsulated homes.

Roof Insulation Cape Town have specialised in Loft Room Insulation for many years.

Attic Insulation

Attic Insulation in South Africa is generally referred to as Roof Insulation or Ceiling Insulation.  

As South African roofs have a lower pitch they are very rarely converted into a loft space for living or storage.  

Some homes in the Cape Area have much higher pitched roofs and these are often used for storage.  

The Attic Insulation in these applications the Roof Insulation must be laid flat on the ceiling between the main beams.

In loft Rooms we would obviously insulate the side walls as well as the floor area to give you a more comfortable living area. 

Roof Insulation R-value

Roof Insulation R-value is very important in all building designs. The whole of South Africa has been divided into Zones and all must comply with the SANS legislation with the appropriate R-value for the region that you live in. 

The Western Cape region has a compulsory R-value of 3.70. This is achieved with the Isotherm 145mm thick insulation or the Aerolite 135mm thick.;

Guateng, Johannesburg and Pretoria are also rated for the R-value of 3.70. The Aerolite Insulation and the Isotherm Insulation are perfect for these areas as well.

KZN R-value is rated ideal for the 100mm Isotherm Insulation or the Aerolite Insulation.

The new Sans legislation came into effect as of January 2013. The legislation is the compulsory on all new homes.

What is The Lifespan of Ceiling Insulation?

The lifespan of the Isotherm Ceiling Insulation is one of the best one will ever find. The fact that Isotherm is manufactured from recycled plastic bottles makes it one of the most eco-friendly insulation products on the market. Isotherm also has a 30 year manufacturer guarantee. Isotherm has no resin binders so the fibres don’t fall apart.

The Lifespan Aerolite Think Pink Ceiling Insulation has a life span of 15 to 20 years.

The lifespan of Cellulose blow in paper type insulation has a lifespan of approximately 5 to 10 years. We find when we vacuum it out of roofs it is combustable after about 5 to 6 years. Obviously paper has a host of chemicals to create fire retardant and also chemicals for rats and vermin.
