Build it tight – Building envelope design and application using European tapes and membranes. 1.5 hours 11AM - 12:30 PM.  

Ventilate right - Heat Recovery Ventilation planning and economics for multifamily buildings. -1.5 hours  12:30 PM - 2PM

Workshop details are suitable for Passive House and other low load building types. The workshop goal is to offer practical solutions to help achieve low load goals. The solutions are specific instructions on methods to achieve high reach goals. They are specific to product manufacturers and therefore not “generic” or suitable for AIA credits.

We are changing our name to Small Planet Supply.

When we started as a company in late 2009, the workshop part of the name was chosen to reflect the company's early role as a place to think about and find solutions to the sourcing and application problems of super-insulated and air tight assemblies that would be the backbone of North American Passive House development. Now in 2015, it's time for the company to change its name to Small Planet Supply, as more people know us as a mainstream supplier delivering the solutions it had worked out and brought to market as a niche thinker solving problems in its early days.

Coming soon will be a new website and more new products for low energy buildings. In the fall we will be introducing the Sanden CO2 air to water heat pump hot water heater for both domestic hot water and space conditioning, more cavity insulation systems, and a new PHI-certified facade support system for low density mineral wool exterior insulation applications. 

Projects and Products

The Small Planet Workshop is your link to knowledge and access of specialty products for the High Performance Building Envelope. We can help you select from some of the world's best air sealing tapes, membranes and speciality window installation / weather sealing materials. Most products are available to ship anywhere in North America. For the Pacific Northwest region, we are the source for Intus Windows and the stocking dealer for Zehnder ventilation systems.

Now in two locations: Tumwater WA and our new Satellite Store: Bellingham WA with a full range of SIGA and Prosoco Fast Flash products.


The IP-PHPP is here and available through - the "all things phpp" platform hosted by The Small Planet Workshop.

IP-PHPP: A special project developed by The Small Planet Workshop, energy consultant Dylan Lamar of Green Hammer and the Passivhaus Institut, The PHPP energy balancing software created by the Passivhaus Institut in Darmstadt Germany will now be available in Inch-Pound data entry. No conversion calculators needed and you can review your project sheets in your native units.


Cork boards are available from 1 to 12 inches thick.

New: ThermaCork, Expanded Cork Insulation - 100% Natural - 2013 Top 10 Winner from Building Green.

Now in stock at The Small Planet Workshop: Cork as ridgid insulation that can be used in place of EPS, XPS or Polyiso under the facade. Expanded Cork is R4 per inch, yet still permeable to let moisture "dry through". There are no adhesives, binders or resins in expanded cork. As it's expanded under steam-heat and pressure at the factories biomass plant, the resin within the cork bark (harvested from the cork oak tree) "sweats out" and agglomerates, or "binds itself to itself" into a sturdy cork board. See our Cork info page, or see Expanded Cork Board packs in the Insulation & Sheathing department of the store.

Expanded Cork Insulation as a Building Facade

In addition to standard grade boards for insulation, there is also Facade Grade Expanded Cork that can be used as the building facade. For more information on "cork as a facade", give us a call at (360) 866-8779 or toll-free at 855-FOR-SIGA.

The highest rated (90%+) fully ducted supper efficient HRV's and ERV's are here!  

The Small Planet Workshop is the stocking Zehnder Dealer for the US Pacific Northwest and Western Canada. If you'd like to talk about one of these highest rated systems for your project, please give us a call: We can help you.  System design is complimentary, includes a system layout and project quote -and starts at the link below. Just input your project data and a Zehnder design engineer will plan system flows and a layout. If it's a Passive House, then include the ventilation tab from your PHPP. Please allow 1 week for system design. To read an independent artcle on how a Zehnder system fit into a Canadian Net Zero Home, download a pdf here.
