Leaf House has a new home in the Yukon, Whitehorse, Canada, and is back in the thick of tiny house construction. Plans for version.2 are complete and for sale on the website www.tinyhousing.ca, and Leaf House will be building one more custom tiny house this winter.
The company is testing a variety of innovative materials and technologies suitable for tiny house construction in cold climates. Leaf House is using this upcoming tiny house as a case study, incorporating extremely energy efficient windows, an innovative compact Heat Recovery Ventilator (HRV) for small spaces, a lightweight concrete finish for countertops, metal mesh rainscreen, aerogel insulating material, and lightweight panels and interior finishes.
The most exciting technology showcased in the tiny house, which is the subject of this post, is the vacuum insulated panel (VIP). VIPs are an insulating product that is not yet available in commercial construction but have incredible potential for tiny houses and the recreational vehicle industry. VIPs are thin (1/2” to 1”) yet have an R value of R30 per ½”. The extremely low pressure in the panels prevents heat transfer, and overlapping the panels means that a wall of R60 can be achieved with only 1” thick of material. The panels are filled with silica and are also lightweight. The space and weight savings mean that tiny house construction might just be the perfect application for VIPs. Continue reading
