Thermal insulation materials

Performance The most important aspect of an insulation material is its performance — that it consistently provides the designed-for resistance to the passage of heat throughout the lifetime of the building. For example, insulation slabs need to be installed so that no gaps result either between adjoining slabs, or between the slabs and other construction components that form part of the overall insulation envelope, such as rafters or joists.

The Parallel Path Method sums the R-Values for the various components in a wall assembly through two paths — one through the CFS stud and one through the center of the cavity.


In the Zone Method, the CFS flange width is increased by two times the total thickness of all finish material layers on the thicker side of the CFS member. This has the effect of increasing the amount of area that is assumed to be influenced by the steel member.

The result is a whole-wall U-Factor that can be inverted to yield an effective R-Value for the assembly, although from a code compliance perspective, the main interest is in the U-Factor.

Thus it should be acceptable for code compliance but may unnecessarily penalize a steel assembly.

The Modified Zone Method calculation again breaks the assembly into two paths framed and non-framed and performs the path calculations on each. The Modified Zone Method is believed to be the most accurate calculation method based on comparison to test results and finite element analysis conducted by ORNL.

This calculation method is limited to C-shaped steel members and should not be applied to other shapes. It is also limited to clear wall assemblies, which can be a significant issue given that many walls are not clear wall assemblies. Climate Zones Climate Zone.THERMAL BLANKET INSULATION 07 21 16 - 1.

Fiberglas, Exterior Wall Thermal Insulation. PROJECT ENGINEER RESPONSIBILITY: This is a general specification guide, intended to be used by experienced construction. Double-Sided Thermal Adhesive Tape. Keratherm’s KL90 and KL91 have excellent, permanent adhesive strength with high thermal conductivities and at the same time very good insulation characteristics.

Future Thermal are one of Australia's leading suppliers and manufacturers of industrial insulation and textiles, ceramic and fibre glass, exhaust wrap and more. Building envelope thermal insulation products have been widely used in temperate regions. In many developed and industrialised countries, thermal insulation is a regulatory requirement for energy efficiency and occupant health purposes, which provide a fairly constant market for the thermal insulation manufacturers.
