WHAT IS R-VALUE?
R-value is a measure of thermal resistance. It is expressed as the thickness of the material divided by the thermal conductivity. In layman’s terms, R-value measures how effectively a material slows the flow of heat from a warmer to a colder area. Hence, the higher the R-Value of the material, the better it insulates. All insulation products must state the R-value of the product on the packaging. The combination of THERMGUARD’s high intrinsic R-Value and 100% coverage makes it exceptionally effective.
WHAT IS U-VALUE?
The U-value, is a measure of the thermal transmittance through a structure, such as a roof or wall. U-value is the inverse of R-value. U-value measures the amount of heat flow through a material, hence the lower the U-value, the better the insulating properties.
THERMGUARD has both ISO 9001:2015 Certification and the S.A.B.S. Mark.
THERMGUARD is a member of the Thermal Insulation Products, and Systems Association of S.A (TIASA).
THERMGUARD is fire tested to SANS 10177 Part 5 and 10 test protocols and does not support flame spread. It is classified B/B1/2.
The embodied energy in a product is the energy which was consumed during manufacture.
THERMGUARD has a very low embodied energy as the major raw material, waste paper, has an effective value of zero because it merely has to be transported to the factory rather than to landfill sites. The milling of the product is a relatively low energy process. By contrast, processing of raw materials for mineral fibre manufacture requires extraction and crushing of finite mineral resources by energy-intensive methods.
THERMGUARD uses 12 times less energy to manufacture than polystyrene, 15 times less energy to manufacture than glass fibre and 33 times less energy to manufacture than polyurethane. The construction of buildings with low embodied energy is thus an important objective for Architects given South Africa’s ever increasing energy demands.
