Furring-Master™- Steel Furring Strips What is Rain Screen Technology?

The preferred method for deterring rainwater intrusion into walls is rain screen approach. Residential applications of rain screen technology are being promoted heavily as a Best Practice solution by industry experts and in recent studies commissioned by Federal Government agencies such as HUD and U.S. Department of Energy.
Rain screens shed most of the rain and manage the rest, preventing moisture intrusion and the resulting premature decay in homes. Rain screens tackle the source - the forces that drive water into the building shell, namely wind-driven rain. Rain screens effectively keep the moisture away from the exterior wall and insulation.
Furring-Master’s hollow back construction allows maximum drainage, providing a gap needed to form a capillary break. This gap allows proper venting and dries a wall out faster. The steel will not trap moisture behind the strip like wood furring strips or plastic battens. The steel strips are guaranteed for 50 years.
Benefits of a Vented Rain Screen:
There are a couple of key benefits to using a vented rain screen assembly on any building to improve the performance and durability over the life of that building.
	1.) Equalized pressure means less air infiltration inside your building. Since there is an air gap between the exterior sheathing and cladding, the pressure is equalized with the exterior atmosphere. I’m no scientist, but basically this means that air is not going to be fighting hard to enter your building when it hits the cladding because the rain screen has eliminated the large pressure difference that usually exists between the exterior and interior of the home and various layers in between. This helps when you are trying to build homes as air tight as we are in order to achieve maximum energy efficiency.
	2.) Water the makes it past the cladding will drain and dry out, keeping the guts of your walls dry. This is where the durability claims come from. Water will eventually make it through any and all cladding assemblies on a building. The vented rain screen makes sure that when water does get through, it is able to drain down the face of the Water Resistive Barrier and out the bottom or simply dry out on its own due to the air gap behind the cladding. This not only helps to keep moisture from getting into your walls assembly (which is bad), but it prolongs the life of whatever cladding is used by allowing it to dry out when wet from both sides.
	3.) An extra layer of air keeps your building cooler. In most homes, the sun hits your cladding which is in direct contact with the sheathing. The heat from the sun is transferred directly from the cladding into your walls. This makes your building warmer than necessary. The air gap created by a rain screen keeps the face of your sheathing much cooler.
