In general terms a rain screen is a sustainable design system that keeps rain (and other elements) away from the building envelope of a structure. By moving the siding material away from the building envelope (weather tight outside area of structure behind the rain screen siding), a gap is formed between the envelope and the siding creating a "rain screen". Of course rain is not the only element a rain screen protects the structure from, a properly designed and built rain screen system will shield the building envelope from snow, sleet and more.
In a rain screen system the gap between the building envelope and the exterior siding also provides a passive insulation cavity that helps save energy. When it is hot outside, this buffer zone behind the rain screen allows the hot air outside to cool off, shielding the interior of the home or structure from the thermal impact. Likewise, in colder climates or when there is cooler weather in any climate, this air space behind the rain screen provides the same buffer zone to prevent the transmission of heat gain or loss which creates a more energy efficient design.
What is thermal bridging in a rain screen? Thermal conductivity is the ability of materials to transmit heat or cold. When materials are connected to or touch one another a thermal bridge is created. Typically, the less material that touches another material, the less transfer of heat or cold. With regards to rain screen systems, the less material contact (thermal bridging) , the less transfer of heat or cold.
With a typical wood siding system there is full contact of the wood siding to the building envelope. This allows the direct transmission of heat throughout 100% of the surface area. In a rain screen system using furring strips, the furring strips become a thermal bridge. The furring strips come in contact with roughly 16% or more of the surface area of the building envelope, creating a rain screen design which has 16% or greater thermal bridging.
The Climate-Shield™ Rain Screen System uses no furring strips. The surface area of the Climate-Shield rain screen clip that connects the wood siding to the building envelope is less than 3 square inches. This creates a rain screen system that has minimal thermal bridging. The Climate-Shield™ Rain Screen Clip allows design professionals a rain screen design option to reduce thermal bridging to less than 1% of the surface area of the building envelope.
Additionally the removal of the furring strip from the design creates:
significant labor savings
material cost savings
better air flow behind the rain screen
better evaporation behind the rain screen
a healthier system by eliminating potential mold and mildew problems

With its long lasting natural characteristics yet affordable pricing, Cumaru Decking is gaining momentum as a popular premium high density hardwood decking material option.
How strong and hard is Cumaru Decking? Is Cumaru decking as strong as Ipe decking?
Ipe decking is generally regarded as the ultimate standard to which all other decking materials are compared. Cumaru Decking is also one of the hardest and strongest decking materials on earth. Cumaru decking is a high density hardwood that is nearly as hard and strong as Ipe decking. While both Ipe hardwood and Cumaru hardwood species are so dense they will actually sink in water, Cumaru Decking is slightly more dense than Ipe Decking!
From a strength standpoint, Cumaru decking has an amazingly high fiber bending strength of 22,400 psi. That means that it would take 22,400 pounds per square inch of pressure to break a cumaru decking board! Cumaru decking is 96% as strong as Ipe decking (23,600 psi)
When looking at material hardness, you will find that Cumaru decking has an incredible Janka Hardness rating of 3,340 lbs. The Janka hardness test is a measure of how many pounds of pressure that it will take to press a .444" steel ball half of its diameter into a board. This test reveals that Cumaru decking is 91% as hard as Ipe decking (3,680 lb. Janka rating).
Cumaru decking has many natural characteristics that make it a great choice for a backyard deck, dock, pool deck, bridge, pier, boardwalk and more.

The Greenbuild Expo in Toronto was an energizing and exciting event. If you were there, then you know first hand how big the show was and how many interesting new products were displayed. If you missed Greenbuild, please allow me to fill you in on a few highlights. Members of the design and construction communities were out in force and were well represented by their colleagues. Over 1,000 suppliers exhibited the latest sustainable products and technology on the market.
While we received a lot of interest in our Climate-Shield Rain Screen Wood Siding system, one of the hardwood species that drew a surprisingly high amount of attention (in our opinion) at the Greenbuild Expo was Cumaru decking and Cumaru rain screen siding. We thought that more design and construction professionals were aware of the advantages that Cumaru lumber and Cumaru decking offer the design community. The Greenbuild Expo served as an excellent starting point to get the good news out about Cumaru hardwood.
Architects and design professionals were intrigued by the extremely high density and strength characteristics of Cumaru hardwood lumber. Cumaru decking and Cumaru lumber are nearly as hard and strong as Ipe decking and Ipe lumber. Cumaru decking, Cumaru siding and Cumaru lumber actually exhibit a slightly higher density than Ipe hardwood.
Green builders were excited about the reddish brown coloration and exotic graining appearance of Cumaru decking and Cumaru rain screen siding. Both design and green construction professionals were also impressed with the affordability of Cumaru decking, Cumaru siding and Cumaru lumber. While Cumaru decking and Cumaru siding have many characteristics similar to Ipe decking and ipe siding, one area where Cumaru is the clear cut winner is the initial pricing. Cumaru decking and Cumaru siding are available with FSC Certification and other sustainable methods.
