Action News Philadelphia investigative team Troubleshoots has been reporting on the growing construction crisis in the Tri-State area for over 3 years. This latest story involves homeowners that are facing major mold and moisture issues with very prominent builders in the area due to defective or incorrect installation techniques. Previous reports by Troubleshooters has investigated issues specifically with stucco homes, but have now found issues with homes including those built with vinyl,...

Water gets into buildings. It’s an indisputable reality. The effects of inward driven moisture can wreak havoc on the structural integrity, durability and longevity of any building. The aftermath leaves homeowners and property managers struggling to fix problems including rot, mold and mildew. For architects and builders, failing to identify these potential risks and specify solutions to mitigate them can become a significant issue in renovation, as well as in litigation. The marketplace is...

Open joint rainscreen cladding is a growing trend in exterior facades. The design concept relies on the performance benefits of a rainscreen, which is a gap behind cladding that facilitates drainage and drying. The open joint allows some incidental water to enter the rainscreen gap, but also promotes enhanced airflow to increase the drying rate. This creates a low-risk wall assembly to the potential damaging effects of moisture. The downside of the open joint design is that areas of the...

​Moisture is the number one cause of exterior wall damage. Drainage is widely accepted as one of the most effective measures for reducing moisture damage due to rain penetration. Drainage is a critical component in allowing the housewrap to do its job – particularly in keeping walls dry. According to a study by John Straube and Jonathan Smegal of Building Science Corporation, a 1mm drainage gap “will drain water at a rate considerably greater than rainwater is expected to penetrate behind...

​A rainscreen system, such as our Slicker family, was designed for regions of the country prone to wind-driven rain, excessive amounts of rainfall, or high temperature and humidity. Wind-driven rain from the outside and moisture vapor from the home’s interior, often remain trapped in the sidewall assembly. Left alone, this moisture can promote the growth of mold and undermine the structural integrity of the wall. For wet and/or humid climates, coastal areas and hilltop exposures...

Yes, you can use Cedar Breather for side wall applications under your siding material. Similar to our Slicker Rainscreen, Cedar Breather maintains a 1/4” gap to promote airflow and ventilation. The difference between Slicker and Cedar Breather resides in the color and manufacturing process. Slicker is yellow and contains vertical channels designed to promote drainage. Cedar Breather is black and has a conical shape pattern to promote circulation under cedar roofing materials. Depending...

Slicker products are faster and easier to install, cutting labor costs. Slicker products provide a continuous vented airspace over the entire surface area of the wall, providing greater drainage and more effective drying than wood strapping which only vents approximately 85% of the wall. (1x3 strapping installed 16 inches on center leaves 15% of the wall unventilated.) Unlike wood furring that is subject to saturation and decomposition in a relatively short period of time, Slicker...

The main difference between HydroGap Drainable Housewrap and Slicker Classic rainscreen is the size of the gap that each provides. Both allow water to drain, but Slicker Rainscreen offers ventilation that promotes drying. Slicker Classic is a true rainscreen, meaning that it provides a 1/4-inch (6mm) gap between the sheathing and the cladding. This 1/4-inch gap provides for both drainage AND continuous airflow (drying). Slicker Classic by itself does not act as a WRB (water-resistive...

A drainable housewrap, like HydroGap, incorporates both a water-resistive layer and a drainage gap, greatly facilitating water drainage from behind the exterior siding. Unlike typical housewraps, which provide only a water-resistive layer and can trap water behind siding, drainable housewraps provide a continuous drainage gap that allows water to quickly escape from the wall system, protecting the building enclosure. There is growing recognition that walls systems need to drain, and...

What is a Rainscreen?

A rainscreen, like our Slicker products, is essentially a 1/4-to-3/4-inch air gap built in-between the the exterior siding and sheathing of a wall assembly. When combined with a WRB, a rainscreen is designed to reduce the forces that draw water into the your sheathing. Water that does reach the back of the cladding is permitted to drain from the wall assembly via the space created by the rainscreen. A rainscreen offers accelerated drying of water vapor that accumulates in-between the siding...

This builder didn’t CYA, find out what happened. Building failures due to moisture issues have been a common theme in the building industry. Failures in newer buildings often stem from the use of products that lack the capabilities necessary to remove moisture from the wall assembly, causing most issues you see today. Many builders and contractors are realizing it’s better to pay a small upfront cost increase than to have to repair damage down the road. The need to incorporate...

A valuable article in this month’s ProSales Special Report by Charles Wardell addresses the importance of building durable, moisture-resistant buildings. Moisture accounts for about 80% of construction defect litigation, so while lawyers may love the stuff, no one else benefits. In the worst cases, moisture trapped in the framing assembly can lead to rot that weakens the structure and to mold growth that makes a home unlivable. Problems need not be catastrophic to cause major headaches....

One of our most frequently asked questions is what is the difference between a rainscreen, drainable housewrap and a flat housewrap? The answer all comes down to the gap. A rainscreen like any from the Slicker family provides a ¼ in gap behind your cladding. A ¼ in gap is considered a “big gap” for drainage and drying performance. Drainable housewrap like HydroGap provides a 1 mm gap behind your cladding. The 1 mm gap is considered a “small gap” for drainage performance. And...

Lots of housewrap manufacturers emphasize the importance of vapor permeability related to their products. Vapor permeability is an important characteristic in choosing a housewrap. If water vapor escapes the interior conditioned space or liquid water gets behind the housewrap from the exterior, the permeability of the housewrap protects the sheathing. It allows for water vapor to escape through the exterior of the housewrap. But what does Vapor Permeability mean? Permeability measures the...

Doing More Matters

Why doing more than just the minimum matters. All too often we hear in the field, “If it meets code, it’s fine,” or “I don’t see the value in paying a premium for something inside the walls,” or even “the cladding is water tight, I’ll never have a problem, the housewrap doesn’t matter.” As you know, a water resistive barrier is more than just a water barrier; it helps to maintain the structural integrity of the wall. If it fails, the entire wall fails. Surfactants, or...

Elimination of seam tape allows for unrestricted drainage path (no reverse flashing). 2. Drainage space provides path of least resistance down and out of the wall system – moisture won’t migrate laterally at...
