ENVELOPed'S FOUNDER & MD
MURRAY DURBIN
Murray has worked in the building supplies and construction industry his whole career. With senior positions at head office levels at Mitre10 and Carters he understands the complete supply chain. Murray launched Mammoth Insulation in 2012, then went on to set up Knauf Insulation in New Zealand and ran the business for 5 years securing a large percentage of the domestic market for bulk insulation. This included launching new and innovative products such as Jetstream MAX.
Murray assisted with the build of the first Passive House in Australasia (PH1NZ), then went on with his partner to project manage and build the first Passive House Plus certified home in Auckland in 2015 "The Ideal House", which also carries a 10 Homestar built rating. The Ideal House was open regularly for over two years to showcase the latest in design and materials, and featured in numerous publications. The home was monitored by the University of Auckland and can maintain 18 degrees all year without any external heating sources, and can hold a comfortable 23 degrees with a heater the size of a toaster. It features high levels of Earthwool glasswool, Intello from pro clima, and Zehnder balanced heat transfer ventilation amongst other materials.
Murray has spoken at numerous national roadshows as well as tours of Universities around New Zealand on high performance homes. Murray and his team look forward to helping others achieve the same comfortable, healthy environment he is able to bring his children up in.
