Rain Screen Installation: Tips on Using Scarf Joints

Rain Screen Installation Tips for Contractors

A scarf joint works exceptionally well on wood siding boards using the Climate-Shield Rain Screen System. Using a scarf joint is a widely accepted technique with professional woodworkers for various types of construction and woodworking projects. A scarf joint looks great architecturally and functions well from a performance standpoint. Although linear wood expansion and contraction is only minimal, any small movement of the wood siding boards is covered by the design and function of the scarf joint. When using a scarf joint, you don’t have to worry about a butt joint opening up slightly and exposing the wall cavity in a rain screen system.

Use safe construction practices and techniques to cut a miter at the ends of the siding boards with the Climate-Shield Rain Screen System.  In the picture above, the craftsman is cutting a piece of 1x4 Cumaru hardwood siding with a 45° mitered angle on a standard miter saw.  In the picture below you can see the overlap created between the mitered ends of the rain screen siding. This overlap provides coverage for any minimal expansion and contraction of the siding to look beautiful in any weather conditions.

When installing the Climate-Shield Rain Screen Wood Siding System, you can use a single rain screen clip to straddle the gap between the mitered ends of siding boards. This technique effectively holds two siding boards in place with one single sturdy rain screen clip. Because the Climate-Shield uses two stainless steel screws for fastening, the joint still exceeds all strength requirements to meet construction codes for hurricane prone areas.

When you install the Climate-Shield Rain Screen System over any structural sheathing such as OSB or plywood, there is virtually no wasted siding, because it is unnecessary to cut off the ends of the siding boards to meet a furring strip. What!?  How can this be?!  Simple- the Climate-Shield rain screen clip is designed to provide secure fastening and create a uniform rain screen wall cavity without using any furring strips, saving installers time, money and aggravation.
