NEW! Finally!! A Self Adhered Exterior Membrane that will apply in cold weather without a Primer.

Love the ease of installation and sense of confidence you get from a high quality self adhered membrane?

Tired of applying them with primers or having to wait for better weather? In February??

Your membrane just arrived into stock.

SIGA Majvest 500 SA applies in cold temps and without a primer. Installation temperature: -10C/14F

SIGA Majvest 500 SA is a vapor-permeable, 3-ply membrane, with the reverse face fully coated by a pressure-sensitive glue for direct bonding to substrates. The adhesive side of the sheet is protected by a white, siliconized, split-release liner which is removed during installation. Primer-free adhesion to most common building materials, including concrete, plywood, gypsum, and metal. Narrower 18” roll size, for use in construction sequencing, pre-stripping, and smaller sections of the wall field in above-grade wall applications.

SORRY! AVAILABLE IN USA ONLY! Available in Canada late Spring 2018

Wouldn't it be nice if you could ask your wood framed building assembly to take direction? From you?

Now it can.  

Swiss membrane maker SIGA has created the worlds first directional vapor control membrane. The class of "Intelligent membranes" started the process off by allowing vapor permanence to self adjust and follow relative humidity. Thats good... but it can be tricky... since the water vapor can travel in either direction. And the more vapor there is, the more it can flow. in any direction its driven. That's not the best case when you're trying to dry out a wood-framed building.   

Utilizing SIGA's new Hygrobrid technology, Majrex is the vapor control layer that allows moisture travel in only one direction. Now you can control the drying direction of your assembly. Even better, is that you can also create "directional assemblies". The "directional" aspect allows you to create a wall assembly that will have a significantly higher permeance to let water "leave" the assembly, while the reverse pathway "into" the assembly has a very low vapor permeance to inhibit the inbound flow. The same directional aspects can be set into a roof assembly design: Encourage moisture to leave the assembly with high permanence and discourage moisture from entering with low permeance.  

This protects the interior of the wall assembly from damaging moisture penetration and allows the cavity to release moisture into the interior of the space (as well as to the exterior if one is using a vapor-open exterior membrane, such as SIGA Majvest), while preventing moisture intake from the inside. 


New! Sanden CO2 Heat Pump Hot Water Heaters are in stock and ready for delivery at Small Planet Supply.

Efficiency that is truly revolutionary

We are excited to bring CO2 heat pump technology to North America this winter with a new series of UL/CSA listed heat pump hot water heaters from Sanden of Japan.

The system replaces standard heat pump refrigerants with CO2, which dramatically increase the efficiency, while eliminating the global warming potential of standard refrigerants. It's a double whammy of effectiveness achieved by collecting CO2 from manufacturing waste streams.

At a capacity of 15,000 BTU/hr, the system can be a simple dedicated hot water heater, or can be designed into a COMBI SYSYEM that supplies both domestic hot water (DHW) and heat for your energy efficient home (space conditioning).

Space conditioning delivery methods can range from hot water radiators to a full radiant floor system. Contact us for more information. Read more about Sanden.
