I wouldn't recommend Perth Insulation whatsoever.
I accepted a quote and made a firm booking to have my small apartment done only 3 days later, confirmed by email.
I took a half day of my annual leave to meet the workers but no one showed up. When I telephoned the same sales person at first didn't know who I was but then suddenly said that he had sent me a text message the day before postponing because they were still busy with a bigger job. There was no SMS message. They were to get back to me but never did.

Great service and cheaper than I was first told . They quoted over the phone using google maps measuring the roof witch surprised me but was spot on . The job was completed 2 days later . Thanks to the team at Perth insulation

Approximate cost: $1700
