In fact, Thermal Insulation for Roofs is the ability of a given Insulation to reduce the transfer of heat. In fact, Insulation for roofs and ceilings will reduce the heat flow in or out of the home. Therefore this will improve the heat loss or gain in the home by up to 90%.

Thermal insulation is the reduction of heat transfer (the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in the range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.

Heat flow is an inevitable consequence of contact between objects of differing temperature. Roof insulation provides a region of insulation in which thermal conduction is reduced or thermal radiation is reflected rather than absorbed by the lower-temperature body. This Quote from

The insulating capability of a material is measured with thermal conductivity (k). Low thermal conductivity is equivalent to high insulating capability (R-value). In thermal engineering, other important properties of insulating materials are product density (ρ) and specific heat capacity (c).

Thermal Insulation for Roofs

Thermal insulation

Therefore Roof Insulation must be laid flat on the ceiling. The best Thermal Insulation benefit will be achieved this way. The Ceiling must be sealed from energy loss. Also, do not compress Insulation as the R-value will be reduced.

The proper application is to cut the insulation slightly wider than the beams. Insulation must have a tight fit to be effective. Isotherm has really good thermal properties as does Aerolite.

Isotherm Thermal Insulation

Thermal Roof Insulation is the major player in the South African Roof Insulation market. Recommended thickness for the Cape is  Isotherm 145mm thick Roof Insulation. This is the thickest Insulation on the market.

  • Isotherm Insulation is dust free as well as allergy free.
  • In fact, Isotherm Insulation is backed by a 30-year manufacturer guarantee
  • As a result, the Isotherm 145mm has the recommended R-value of 3.70as specified for the Western Cape region.
  • The Isotherm is dust free and allergy free.
  • Isotherm Thermal Insulation will reduce the need for heating and cooling and will pay for itself in Two to Three years. This, in fact, will then allow for many years of energy saving.
  • Thermal benefits of Roof Insulation are one of the most important factors in conserving energy worldwide.
  • With Isotherm Thermal Insulation is also critical to install insulation with higher R-value to achieve better Thermal Properties from the insulation.

Aerolite Thermal Insulation

Think Pink Aerolite Thermal Insulation is also a roll form insulation. This will reduce heat flow up or down in the home keeping the home cooler in summer and warmer in winter.

  • In fact, Think Pink Aerolite will last more than 20 years
  • The Aerolite 135mm is Sans compliant achieving the R-value of 3.70
  • Thermal benefits of Aerolite Insulation are great. The fact that the Aerolite insulation will pay for itself in two to three years is a testament to the great thermal properties of this Roof Insulation.
  • The higher the R-value of the Aerolite the better the Thermal Properties of the insulation.
  • Lower R-values will have a lower thermal property.

What is Thermal Insulation

Thermal Insulation will reduce heat flow. The insulation type used will affect the heat flow. The higher the insulation R-value the better the insulation properties. Insulation R-value is the measure of the insulation’s ability to reduce heat flow. A home under insulated will not have good thermal properties. The Thermal properties of insulation installed are critical to getting the best results.

Thermal Insulation for homes is vastly different the Insulation for industrial plants. However having said that they all have to have great thermal properties. For the homeowner, the highest R-value is the best Thermal Insulation properties.

In industrial plants and boilers, density and thickness of the mineral wool insulation are the managing factors to the thermal properties of the insulation. So the highest density and the thickest product will give the best Thermal Insulation properties.
