INSULATION MATERIALS

Ashinkyle South Africa

• Insulation materials often differ in terms of their thermal resistance/R-value, cost, environmental impact, and application.
• Consumers now have access to a wide variety of different insulation materials.
There are a wide variety of insulation materials available, ranging from the main fiber materials like rock, slag wool, fiber glass, and cellulose and from natural fibers to sleek foils and rigid foam boards. The more bulky materials have the ability to resist both conductive and convective heat flow, to a lesser extent, in building cavities. By contrast, conductive heat flow is resisted by rigid foam boards by trapping air and gas. In addition, reflective foils and insulation work by reflecting radiant heat outwards from living areas, which make them quite useful in cool climates. There are also other materials available that are less common such as vermiculite and perlite and cementitious and phenolic foams.

TPH can be applied over other plaster or fibre insulation (blanket or modules), providing the sub-structure has been wired and/or secured with wire mesh or, expanded metal in the case of flat overhands.
Best results are obtained by applying two coats of 5.8mm thickness allowing the first coat to dry before the second coast is applied.
