Getting more out of YOUR Insulation.
Episode 1 - This video should be watched before installation of insulation, electrical services, and plumbing in a new building or an extension/renovation.
This video seeks to improve the quality of insulation installation during construction so the home meets the owners expectation.
This is the first of 3 videos in this series that provides training for trades and supervisors on how to apply insulation and plaster and airtight practices that complements the air barrier in residential buildings.
Insulation performance is highly dependant on the way it is installed. Some key areas that are covered in this video are:
How does insulation work? (covers: consistency, air-barrier/ thermal barrier continuity, do not suspend away from the air-barrier, mitigation of problem areas)
How is insulation installation checked? (thermography and visual inspection)
What is important to consider when installing insulation? (Height of insulation, specified R-value, consistency)
How should insulation negotiate the roof around the perimeter of a building? (Conduction risks around the perimeter, avoid splitting R5.0 Batts for the perimeter, use appropriately sized batts for the perimeter e.g. R2.7)
How should insulation be installed in the ceilings? (covers proper installation, skylight wall installation, Voids, services platforms, manholes and floors above a garage)
How should insulation be installed in the walls? (covers vapour permeability (Vic BCA), recessed Electrical Switch boards, wall insulation thickness, proper installation, consistency, unconditioned spaces, T and L Junctions, Wet (Bathroom/Laundries/Toilets) areas, Lintel insulation, cathedral walls, bulkheads, electrical wiring)

Energy efficient homes can provide homeowners with:
better quality homes that are naturally more comfortable in winter and summer.
significantly lower energy bills; and,
significantly reduced greenhouse gas emissions.
Homes can be tested to ensure it is built to meet the designed energy efficiency standard by using:
blower door tests; this test uses fans to simulate wind blowing against the building’s exterior to identify air leakages in the building’s envelope.
Thermal imaging; this is used in conjunction with the blower door testing to locate missing or poorly installed insulation that may result in the movement of warm or cool air in and out of the building.
Independently testing and inspecting each home confirms compliance to the designed quality of energy efficiency inclusions.
