This airspace has profound influences on the physical effects of rain on our dwellings and their ability to dry out after getting wet. Building researchers find that these techniques combined with proper flashing of weather barriers, is one of the best ways to boost the durability of homes and buildings. There are many specific benefits that people attribute to rainscreens but they are mostly variations on these two themes.
In particular, the rain screen requires the following:. An excellent article by the Norwegian Building Research Institute provides a detailed discussion of these design and construction techniques. Prior to installation, the moisture content of the rain screen siding boards should acclimate to the relative humidity levels of the local environment.
Other than higher cost over what we consider snake-oil exterior siding products cement-board, vinyl, aluminiumthe biggest problem with wood siding is the potential for mold growth and rot. Rot, mold, and mildew are all caused by fungi which flourish pretty much wherever there is water, food, and oxygen. It is important for wood siding to be able to dry out quickly to prevent fungal growth, especially in regions with wetter climates.
New Orleans is the home of jazz, Mardi Gras, and rot. I grew up about 70 miles southwest of NOLA so I know a little something about the rain and the swamps and the muggy air. It makes it tough on buildings because the moisture comes from so many directions, but it is possible to control moisture there.
The product contains no chemicals, and is suitable for all weather conditions. Care must be taken to install and maintain it correctly to ensure you enjoy its beauty for many years to come. Provided the correct installation method is used CFP Woods thermally modified wood siding can last for many years.
This novel approach to real wood siding combines lessons learned from buildings constructed hundreds of years ago in Europe with marine grade aluminum alloy clips and hardware - producing a variety of finished siding appearances horizontal, vertical, angled that are free of unsightly fasteners and hammer marks. And best of all, the fundamentals of the installation are consistent with wood siding, shingles, clapboards and tongue and groove siding products. Level lines, corner and window trim details, as well as attention to flashing details are part and parcel of all siding systems and the Climate-Shield rain screen system is no exception.
HI, guys. I'm back again asking about drainage planes and cedar. Trying to find a balance between the perfect world scenario and budgetary reality. Our options thus far seem to be:.
The rain-screen method of building construction gives a secondary barrier and drainage plane for water. Sheathing is placed over the studs and a water-resistant barrier usually Type 30 felt is applied. Although the shakes and shingles are not nailed directly to the sheathing in rain-screen applications, most codes still require plywood sheathing.
