How Insulation Works

How it works

Heat moves naturally from areas of high to lower heat within your house, and all the building materials used in your house either absorb heat or help to transfer it. If your home is heated in winter, that hot air will continually try to move to the outside of your house, where the air is cooler. In the summertime, hot air from the outside will constantly try to flow into the cooler space in your house. Insulation works to prevent this transfer of heat.

Air is a poor conductor of heat and hence it is an effective insulator, as long as it is not allowed to move. Due its fibrous nature, cellulose traps large volumes of air which acts as a barrier to heat movement.

In summer, the heat beats down on your roof, often making the temperature in your home unbearable. By installing THERMGUARD, you will be able to prevent the heat flowing downwards into your cooler home by up to 89%! Depending on where you live, this will make your home naturally more comfortable to live in, or in very hot areas, reduce your air-conditioning bill considerably. In fact, the insulation will pay for itself within 3 years of installation.

During the freezing winter months, heat is generated in your home by using electric and gas heaters, or in your fire place. THERMGUARD will keep your home warm by retaining the heat generated inside the house, thus reducing your energy costs and improving your comfort. When fitted at 135mm, the reduction in heat flow in winter will be an amazing 92%!

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.

Embodied Energy

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 10 times less energy to manufacture than glass fibre insulation and 14 times less energy to manufacture than polyester insulation. In addition to the low energy manufacturing process, no water is used to make Thermguard. The construction of buildings with low embodied energy and water is thus an important objective for Architects given South Africa’s ever increasing energy and water demands.

Certification

THERMGUARD has both ISO 9001:2015 Certification and the S.A.B.S. Mark.

THERMGUARD is a member of the Thermal Insulation Products & Systems Association SA (TIPSASA).

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.
