Meet the Climate-Shield CS2 Rainscreen System

The CS2 family of Climate-Shield rainscreen components is the most robust rainscreen system. The CS2 system is ideal for all types of residential and commercial wood rainscreen designs over plywood or OSB sheathing. the CS2 system creates a 3/4" rainscreen gap in the wall cavity, considered the ideal depth by building scientists. There are also additional components available for the CS2 that are ideal for installations over masonry, concrete and exterior gypsum.

Where to use the Climate-Shield CS2 rainscreen system:

You can’t go wrong with the CS2 system on any residential or commercial project design that has plywood or OSB exterior sheathing. The CS2 system components automatically set a ¾” rainscreen gap without the need for furring strips. The pressure equalized, open joint design affords the fasted drying times to keep the wall cavity clear of bulk water and moisture. The CS2 rainscreen components work great for siding and soffits.


Best Rainscreen Design Applications for Climate-Shield CS2 System:

  • Horizontal siding for homes and buildings
  • Vertical siding for homes and buildings
  • Soffits of all types
  • Exterior ceilings requiring ventilation.
  • Projects that are in hurricane zones and high wind zones
  • Projects with exterior gypsum wall assemblies (with CSAC8 Attachment Channel)
  • Masonry walls (with CSAC8 Attachment Channel)
  • Projects with exterior insulation (with CSZG Z-Girt)


What Rainscreen Components are available for the CS2 Family?

  • The Climate-Shield CS2 rainscreen clip is the heart of the CS2 family. The CS2 clip has been described by architects as elegantly simple. And rightfully so. The CS2 rainscreen clip eliminates the need for furring strips over plywood or OSB. CS2 rainscreen clips install securely with two stainless steel screws.
  • The CSSR8 horizontal starter rail is installed at the bottom of a horizontal siding wall assembly. This eight-foot time saving component installs quickly and level for horizontal siding installations. Once you set this easy-to-install component level, all your siding will The CSSR8 starter rail has predrilled holes for easy mounting and weep holes for quick water drainage at the bottom of the wall cavity.

  • Cor-A-Vent SV5 is a ¾” thick siding vent that installs directly above either the vertical or horizontal starter rail. At the bottom of the wall cavity, it minimizes the potential for insects from entering the wall cavity (rainscreen gap). At the top of the wall assembly, the SV5 siding vent is perfect for ventilation and prevents insect penetration.
  • The CSAC8 Rainscreen Attachment Channel is ideal to create a fastening point for the CS2 rainscreen clips on masonry walls, CMU, exterior gypsum, and other wall assemblies where there is no plywood to fasten the CS2 rainscreen clips to directly.

The CSAC8 attachment channel acts as a metal furring strip and will not rot like wood furring strips. Like the CS2 rainscreen clips, the CSAC8 attachment channel is made from marine grade aluminum, so there is no galvanic action between the clips and screws.


  • CSZG Climate-Shield Z-Girt is ideal to create a secure fastening point for CS2 clips on wall assemblies with exterior insulation or to meet elevation requirements. Climate-Shield Z Girts are available with web lengths up to 8” to meet your project needs.

Meet the Climate-Shield CS10 Rainscreen System

The Climate-Shield CS10 rainscreen clip is smaller than the CS2 clip, it is still exceptionally strong, dependable, durable, and very versatile. The CS10 rainscreen clip creates a 10 mm (approx. 3/8”) rainscreen gap and installs quickly with one stainless steel screw. The low profile of the CS10 clip makes it ideal for remodeling and re-siding projects, as well as soffits.

Where to use the Climate-Shield CS10 rainscreen system:

You can’t go wrong with the versatile CS10 system on any residential project that has plywood or OSB exterior sheathing. CS10 is ideal for soffits and horizontal siding installations. Recladding and remodeling projects go smoothly with the CS10 rainscreen clip and CS10SR starter rail.

Here’s why. Because the CS10 rainscreen gap is shallower, the siding face projects only 1-1/16” off the building envelope. This is less than the projection of about 95% of the residential wood windows on the market. That means you don’t have to add extra trim around most window and door openings.


Best Applications for CS10 Rainscreen

  • Horizontal siding for homes and buildings over plywood or OSB exterior sheathing
  • Vertical siding for homes and buildings over plywood or OSB exterior sheathing
  • Soffits of all types
  • Exterior ceilings requiring ventilation.
  • Projects located in areas with winds lower than 160 MPH


What Rainscreen Components are available for the CS10 System?

  • The Climate-Shield CS10 rainscreen clip is the heart of the CS10 family. The CS10 installs quickly, with one screw and creates a shallower rainscreen cavity that minimizes the need for additional trim around windows.

  • The CS10SR horizontal starter rail is installed at the bottom of the wall assembly. The starter rail is eight feet long for easy handling and accurate leveling. The CS10SR starter rail will save you time and aggravation on the job site. Once you set the starter rail on the level, all your siding courses line up perfectly. The starter rail has predrilled mounting holes for quick installation and predrilled weep holes for quick bulk water drainage at the bottom of the wall cavity.


  • The CS10VSR vertical starter rail is installed at the bottom of the wall assembly for vertical rainscreen siding installations. The CS10VSR also has predrilled holes for easy mounting and ¼” weep holes for rapid bulk water drainage.

  • Cor-A-Vent SV3 is a four-foot-long siding vent that works well with the CS10 system. It installs directly above either the vertical or horizontal starter rail. At the bottom of the wall cavity, it minimizes the potential for insects from entering the wall cavity (rainscreen gap). You can use the Cor-A-Vent SV3 at the top of the wall assembly, too. This helps promote top of wall ventilation and minimize insect penetration into the wall cavity.

Climate-Shield Rainscreen Installation

The installation of the Climate-Shield rainscreen system is much simpler and less costly than other installation methods.  

Installing the Climate-Shield starter rail correctly and level means all your other courses of siding will easily install level, too. Simply install your first course of wood siding level and then install your next courses of wood siding from this secure and level base. 

There is no need to waste wood siding materials by cutting it to fit 16" furring strips- simply install a rainscreen clip (top and bottom) at the end each piece of siding and let it "share the rainscreen clip" with the next piece of wood siding.


Climate-Shield Rainscreen Clip Vs. Other Rainscreen Clips

A picture is worth a thousand words ...

Just look at how rugged and secure the Climate-Shield CS2 Rainscreen Clip is compared to other rainscreen clips. 

As you can see from the photo, other rainscreen clips require the use of furring strips to create the proper 3/4" spacing for the ventilated wall cavity necessary for proper moisture management.  

The wide mounting flange of the Climate-Shield CS2 Rainscreen Clip also provides a sturdy base to ensure that wood siding is properly seated.

How Climate-Shield Reduces Cooling and Energy Costs

Climate-Shield_Rain Screen System Natural Energy Savings

The Climate-Shield Rainscreen System provides the built-in ability to help your home, building or structure minimize solar gain during hot weather, by design.

Because the unique rainscreen system creates an open-joint, back-ventilated and pressure equalized design, hot air rises and stays away from the building envelope.

Natural convective air currents allow the rainscreen gap (wall cavity) to "breathe" and shed excess heat outside the structure.  Hot air that would normally heat up the siding and transfer the heat to the building envelope, is literally carried away naturally.

A common misconception about "rainscreens" is that they are only design for rain. The truth is that this system is equally effective in hot climates, too.The hotter the weather, the more dynamic is this naturally occurring effect of convective air currents. Building scientists agree that the 3/4" wall cavity is highly effective to assist nature.
