Understanding R-Values and K-Factors in Considering Thermal Resistance

Posted on July 19, 2017 by bzabcik

Described in their most basic terms, R-value is a measure of heat resistance, while U-factor (also know as U-value) is a measure of heat transfer (heat gain or loss). The lesser known K-factor is simply the reciprocal of the R-value of the insulation divided by the thickness. What they all have in common is a […]

Posted on July 5, 2017 by Jason Allen

In our prior blog post, Benefits of Roofing Retrofits with Metal Roofing Systems, we looked at the benefits associated with retrofitting an existing building with a new metal roofing system. In this discussion, we will look at several ways to do it. New Sloped Roof Over an Existing Flat Roof Buildings with flat roofs can […]

The Case for Day One Weathertightness Warranties

Posted on June 20, 2017 by kbuchinger

Once upon a time, a “standard warranty” was indeed the industry standard for weathertightness warranties in the metal roofing realm. To make a long story short, this meant that manufacturers supplied a “manufacturer’s standard warranty” based on an initial review of the details to ensure that the roof could be properly installed but left it […]

What to Know About Dissimilar Metals in Metal Roofing Installations

Posted on June 1, 2017 by Jason Allen

While metal roofing is often used because of its resiliency, strength and longevity, there are circumstances under which corrosion and other reactions can become real issues, to the great detriment of the system’s performance and life cycle.  Some basic knowledge and awareness of common causes of galvanic corrosion (also called “electrolytic corrosion”) from the use […]

Benefits of Roofing Retrofits with Metal Roofing Systems

Posted on May 25, 2017 by Jason Allen

Many commercial buildings, and even some residential ones, have low slope or “flat” roofs that can be problematic to maintain. They typically rely on a membrane of some sort that in and of itself is waterproof, but every seam, penetration, flashing, and other detail is a potential leak if not installed and maintained properly. Further, […]

Respect the Module: Metal Roofing Panels are Modular for Good Reason

Posted on May 19, 2017 by Wesley Young

When installing metal roof panels, the sign of a successful installation can be seen in the way the spacing and alignment of the panels are held across the entire roof. Improperly done, the appearance suffers from standing seam lines that are wavy or non-parallel to roof edges. Even worse, the panels can be unduly stressed, […]

Reducing Peak Demand Costs with Cool Metal Roofs

Posted on May 9, 2017 by Candy McNamee

Among the many benefits offered by cool roofs—including a decrease in urban heat island effect or increased roof system longevity—perhaps the most significant is a reduction in peak demand energy usage which directly affects building expenses. Peak demand is the highest point in the day at which a building draws electrical consumption. A facility’s monthly […]

Knowing When to Call the Metal Manufacturer: Part 1

Posted on April 25, 2017 by Wesley Young

Metal panel installers have a tough job—not only navigating the details of the task at hand but also being confident enough to know when to seek the manufacturer’s guidance. Part of overseeing a successful project is for the installer to know when something is out of his or her comfort zone, beyond their expertise, or […]

Useful Tool: FM Wind Ratings RoofNav

Posted on April 14, 2017 by bzabcik

The concept of testing materials and assemblies in buildings has been around since the late 1800s, when John R. Freeman initiated Factory Mutual Laboratories (now known as FM Approvals) to test fire protection systems. Since then, the use of FM-approved building components and assemblies has become recognized as an accepted safety standard for insurance companies, […]
