Iso Polyester pays for itself by reducing the electricity costs of energy-consuming heating and cooling systems.

The soft texture of Iso Polyester makes it is easy to roll out and cut to size. Pleasant to touch, Iso Polyester is simple and safe to install. It is non-allergenic, non-irritant and resilient and does not support the spread of flame.

Iso Polyester is resistant to condensation and associated fungi and bacteria. It retains loft and will not collapse over time.

Iso Polyester is manufactured to standards of quality such as ISO9001:2008. In addition the product is Agrément certified, as well as listed with qualitative industry associations such as TIPSASA.

Iso Polyester complies with SANS 10400, the application of the national building regulations, as an insulation material.

  •  Tested in accordance with SANS 428: fire performance classification B/B 1/2.
  • ASTM – E 84: spread of flame: nil.
  • BS 5803 part 4: does not smoulder.
  • Test reports available on request.
  • For further information contact Brits Nonwoven.

Spread of flame = 0
Smoke index = 160
Smoke toxicity = < 1 (low toxicity)
*SANS 10400 – 1990 The application of the national building regulations.

Composed of polyester. The relatively high melting point of polyester fibres gives Iso Polyester good thermal stability.
Moisture absorption: Iso Polyester does not absorb more than 2% (by mass) of moisture, which is within the limits set by the standard.
*Tested in accordance with SANS 1381: Part I (Materials for thermal insulation of buildings).

The R-Value is the measure of an insulation product’s ability to restrict heat transfer. The R-Value is therefore indicative of an insulation product’s thermal insulation performance. The higher the R-Value the better the performance and effectiveness of the insulation product. The R-Value of Iso Polyester is dependent on the thickness selected.

This is the resistance to the downward flow of heat; sometimes referred to as “summer” R-Values or cooling.

This is the resistance to the upward flow of heat; sometimes referred to as “winter” R-Values or warming.

Iso Polyester Thermal Insulation maintains a comfortable indoor climate all year round; keeping interiors warm in winter and cool in summer.

The measure of an insulation product’s ability to restrict heat transfer. The R-Value is therefore indicative of an insulation product’s thermal insulation performance. The higher the R-Value the better the performance and effectiveness of the insulation product. The R-Value of Iso Polyester is dependent on the thickness selected. The thicker the product the better the performance.

This is the total thermal resistance provided by a roof or ceiling assembly and /or wall, including the insulation material. Total R-Values are the best indicators of performance.

  • 75 mm – 1.53
  • 100 mm – 2.04
  • 100mm – 2.33*

  • 145mm – 3.37*

 

* SANS 10400XA Energy Efficiency in Buildings Compliant

 

 

Depending on the thickness of Iso Polyester installed and the climatic zone, Iso Polyester’s thermal performance is as follows:

In summer: A maximum temperature reduction of up to 7°C when Iso Polyester insulated ceilings are installed in a dwelling with previously no insulation.

 

 

This is dependent on the question of the installation as well as the thickness of the product.

In winter: You get a reduced heating energy requirement of between 40% and 70%.
*Heating energy requirements assessed in the Department of Housing’s standard House using Agrément South Africa’s thermal software.

Homes with Iso Polyester installed in ceilings, around water pipes and geysers can save as much as 21% on their monthly electricity costs. When also installed in walls, Iso Polyester reduces energy consumption for heating by between 40% and 70%; thereby paying for itself in minimal time.

Energy efficient standards have been legislated. This SANS 204 legislation was a directive from the Department of Minerals and Energy (DME) and the Department of Housing. Its purpose is to impose and regulate energy-efficient standards for residential, commercial and industrial developments.

 

 

The degree and choice of thermal Insulation as specified by SANS 204 is dependent on climate regions, construction design, orientation and location. The insulation of roofs or ceilings must achieve a specified Total R value for the relevant climate zone. These R Values range from 2.7 to 3.7(m2.K/W).

 

 

Insulation in walls must achieve a Total R-Value of between 1.9 and 2.2, also dependent on climate zone. Insulation standards for geysers and pipes are also covered in SANS 204.

 

 

As one of the most effective and safest insulation products on the market, Iso Polyester complies completely with these energy-saving initiatives.
