Climate-Shield™ Rain Screen Siding 8' Starter Rail
The Climate-Shield™ 8' Rain Screen Starter Rail CSSR8 speeds up
the installation process and provides an easier method to make sure your first course of siding is perfectly level.
This innovative rain screen siding accessory item is angled back at the bottom to allow any moisture or water in the wall cavity between the rain screen siding and the drainage plane to flow toward the weep holes for rapid removal of any water. The CSSR8 Rainscreen starter rail is effective for horizontal, vertical and diagonal installations of rainscreen wood siding.
Rain Screen Siding Vent
We have found the Cor-A-Vent SV5 siding vent provides an excellent insect barrier and an effective ventilation for the rain screen wall cavity between the rain screen siding and the drainage plane material of the building envelope. The four foot length of the material makes it easy to handle and install.

The Cor-A-Vent SV5 rain screen siding vent is applied at the starter course of siding and also at the top course of siding below the soffit. On gable walls the siding vent can be installed at the top course of rain screen siding just below the rake or gable trim.
The rain screen siding vent should also be installed above door openings and above and below window openings to allow proper drainage, ventilation and as a barrier screen for insects.
Climate-Shield™ CS-2 Rain Screen Siding Clip
The Climate-Shield™ Rain Screen Siding Clip is the heart of this rainscreen wood siding system. It provides a uniform 3/4" wall cavity between the drainage plane of the building envelope and the rain screen wood siding. Like all Climate-Shield aluminum rain screen components, the rain screen clip is made in the USA. Two stainless steel screws are provided with each marine grade aluminum alloy rain screen clip. This ensures a quick and secure fastening to the exterior sheathing.
In the photo above, the Climate-Shield Rain Screen Clip is shown securely fastened with two stainless steel screws to the building envelope. The rain screen clip can be used to "straddle" or "bridge" the ends of two pieces of rain screen siding to speed installation time.
Since the unique design of this rain screen clip eliminates the need for furring strips, it is not necessary to cut the ends of siding boards to accomodate 16" O.C. studs. Simply add a rain screen clip at the end of the siding board and let the rain screen clip "bridge" to the next piece of rain screen siding. This save money by allowing less siding material waste and speeds up the installation time and reduces labor costs.
Window and Door Casing Transition Trim Strip
At the interface of the rain
screen siding to the door and window casing, it is often desirable to have a transition trim strip for a more finished appearance. This can be accomplished by building transition trim strips in the shop or in the field.
In the photo at the right you will see a piece of 3/4" marine grade plywood ripped into a 2-1/2" wide strip. Then you can rip a piece of board stock to match your rain screen siding. Then you pre-drill the back of the plywood through the finish trim board (here we have selected Ipe boards to match the Ipe rain screen siding) and screw it together.
These door and window trim transition strips can be built on site or we can fabricate them for you in climate controlled conditions in our shop. You are free to select any species of wood to match your rain screen wood siding including Ipe, Cumaru, Garapa or FSC Machiche.
Once this door and window trim transition component is built, you can trim it to length on site and install it over your building envelope abutting your weather-tight window and door openings. Since the 3/4" marine plywood is covered by the rain screen wood siding, this step must be performed prior to installing your rain screen wood siding.
