THE BASICS. Get it
ISOTHERM THERMAL INSULATION is made from 100% thermally bonded, people-friendly polyester. The polyester fibre is produced from recycled PET bottles.
The soft texture of ISOTHERM insulation makes it easy
to roll out and cut to size. Pleasant to touch, ISOTHERM is simple and
safe to install. No loose fibres or itching. It is non-allergenic, non-irritant
and resilient.
Providing excellent thermal and acoustic insulation, ISOTHERM is ideal
for use in both roofs and walls.
Get it. KEEP IT.
ISOTHERM is rolled and packaged in branded clear plastic film, which carries the Agrément South Africa logo as proof of its accreditation.
ISOTHERM must stay dry. It must not be exposed to a naked flame and any other ignition source. Keep this in mind when storage arrangements are being made.
ISOTHERM is resilient and does not shed loose fibres; it withstands normal handling during transportations and installation.
Non-Toxic
No chemical additives, no odour or emissions of volatile organic compounds.
Flammabilty
Tested at the CSIR in normal over-ceiling installation, the spread of
flame was pronounced “negligible”.
Polyester
No loose fibres – no itching.
No rashes – even after prolonged skin contact.
ISOTHERM is non- allergenic.
Maintenance
Free
ISOTHERM is resistant to condensation and associated fungi and bacteria.
ISOTHERM retains loft and does not degrade over time.
Eco - Friendly
ISOTHERM is made using polymer from recycled PET bottles and is completely
recyclable.
Energy Saving
ISOTHERM saves energy.
In less than 3 years ISOTHERM can pay for itself by savings on electricity
usage.
Get TECHNICAL.
Get the R-Value
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 ISOTHERM is dependent on the thickness selected.
Up R-Values
This is the resistance to the upward flow of heat; sometimes referred to as “winter” R-Values or warmer.
Down R-Values
This is the resistance to the downward flow of heat; sometimes referred to as “summer” R-Values or cooling.
Total R-Values
This is the total resistance provided by a roof or ceiling assembly and /or wall.
Total R-Values are the best indicators of performance.
ISOTHERM R-Values
40 mm – 0.88
50 mm – 1.10
75 mm – 1.65
100 mm – 2.20
Alkalinity
The pH value of 7.8. Determined as between 6.0 and 9.0 such that it
will not affect or be affected by materials with which it is likely to
come into contact.
*Tested in accordance with SANS 1381: Part II (Loose Fill Thermal Insulation
Material, 3.10)
Behaviour in fire
ISOTHERM does not support combustion when installed as specified and used in applications described. (ISOTHERM may be used as specified for all types of buildings subject to the provisos listed in Part T of Section 3 of SANS 10400*)
ASTM – E84:
spread of flame = 0
smoke index = 160
smoke toxicity = <1 (low toxicity)
*SANS 10400 – 1990 The application of the National Building
Regulations.
Chemical and physical properties
Composed of polyester.
The relatively high melting point of polyester fibres gives ISOTHERM good thermal stability.
Moisture absorption:
ISOTHERM 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)
Quality management
ISOTHERM’s quality management scheme complies
with Agrément South Africa’s requirements.
*Agrement South Africa’s requirements are based on SANS 9001:2000
Quality management systems.
