Roof board’s greater flexural strength and pull-through resistance improves job site efficiency

georgia-paciific-gypsumGeorgia-Pacific Gypsum’s recently enhanced DensDeck Prime Roof Board has demonstrated – in third-party tests-significant attributes that boost job site efficiency. DensDeck Prime 1/4-in. fiberglass mat gypsum cover boards demonstrated 2.5 times greater flexural strength, per ASTM C473 test methodology, compared to competitive 1/4-in. gypsum fiber boards. The tests were conducted by PRI, Construction Materials Technologies, earlier this year.

For contractors using DensDeck Prime, the advantage of flexural strength (the ability of a material to withstand bending loads) is that it boosts efficiency on the job site. Additionally, 1/4-in. DensDeck Prime roof board demonstrate 22% more pull-through resistance than 1/4-in. gypsum fiber boards in the fastener system* tested, and are included in more roofing assemblies with RoofNav approvals for wind uplift performance as a cover board than competitive gypsum fiberboard.

Specific attributes include ease in handling, easy scoring and snapping with no special tools required, which means less breakage and waste — all of which can lead to significant time and potential money savings.

The overall durability and performance of DensDeck Prime-demonstrated in its fire resistance, strength, pull-through resistance, dimensional stability and mold resistance– provides a number of other advantages for contractors. For instance, in adhered, single-ply membrane testing, enhanced DensDeck Prime demonstrated an average of 24 percent better bond strength than the original product, when using solvent-based adhesives. (The average is based on 60 sq. ft./gal. coverage rates.) With adhesives applied more smoothly and consistently, contractors gain potential cost savings on the amount of adhesive used and the labor needed to apply it. Also, the mat edge wrap is on the underside of the board, allowing for smoother application of adhesive and a more aesthetically appealing appearance once the membrane is laid down.

Even more important to roofing contractors is that DensDeck Prime is the first and only fiberglass-mat gypsum roof board with a 90-day parapet warranty for exposure. The parapet application can be left uncovered, while the horizontal application of product is being completed.

CREST helps contractors, consultants, and building owners compare roofing systems

GAFGAF, North America’s largest roofing manufacturer, has recently released CREST, the Cool Roof Energy and Sustainability Tool. CREST helps contractors, consultants and building owners compare the energy cost savings of different roofing systems options.

CREST makes it easy to compare roof design options, varying levels of reflectivity, and multiple thicknesses of insulation. It allows the building professional to print a customized report that includes images of the building site from publicly-available, internet-based mapping services, and searches rebates to the zip code level, including hard-to-find municipal and utility rebates, to give a truer sense of the real costs and benefits of different roofing system decisions. A proposal-quality report is generated for immediate free download.

Since peak electrical demand often occurs on the hottest days of the year, peak energy loading is very important in modeling the effectiveness of cool roofing. To ease the process of projecting peak energy loads, CREST queries both the Oak Ridge National Labs (ORNL) “CoolCalc” and “CoolCalc Peak” calculators in a single step, using an easy to use app-style format.

CREST was developed in conjunction with GreenOhm, a leading technology company that maintains one of the largest datasets of energy efficiency rebates, incentives and tax credits and easily links this information to provide a complete picture to property owners.

GSA releases green building certification systems review

GSAThe General Services Administration (GSA) recently released its review of the Green Building Certification Systems.  Three certification systems passed GSA screening criteria: Green Building Initiative’s Green Globes, U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED), and the International Living Building Challenge.

Five years ago, only LEED passed the screening process.  In its most recent review, GSA determined Green Globes best advanced federal policies in new buildings and recommended LEED for existing buildings.  Out of more than 180 green building certification systems, GSA narrowed its consideration to whole building systems with a third party verification process.

The Center for Environmental Innovation in Roofing (Center) has been an outspoken advocate of the federal government’s use of science and consensus-based green building certification systems.  In November 2011, the Center filed comments with GSA recommending the agency approve Green Globes based on the certification system’s “more economical approach to building certification and the implementation of a true accredited national standard using the ANSI process.”

On Wednesday, May 9th, the Center’s president Craig Silvertooth delivered testimony at a GSA sponsored meeting on the Green Building Certification Systems review in which he highlighted the potential opportunity and challenges involved in the GSA review process.

GSA oversees the leasing and construction of over 9,600 buildings in the federal building portfolio.  The agency is required under the Energy Independence and Security Act to evaluate green building certification systems every five years to ensure the federal government is using the most appropriate programs to promote its own initiatives.  A copy of the review is available on the GSA website.

When it Comes to Roofing, More Layers = Fewer Headaches

If one layer is good, aren’t more layers better? That’s what the Asphalt Roofing Manufacturers Association (ARMA) believe. They install built-up roofing systems that use layers of bitumen and bitumen saturated felts with asphalt. This union creates a monolithic layer that improves durability, increases energy efficiency, and makes roofs safer.

For example, multi-ply, built-up roofing adds stability to your roof so you don’t have to worry about the deterioration of high traffic areas or the placement of solar panels and mechanical systems. Single layer roofs require sacrificial layers for these areas that often prove redundant and ineffective.

To help property owners learn more about multi-ply, built-up roofing, the Asphalt Roofing Manufacturers Association (ARMA) has easily accessible information on their website. New material is added regularly.

GAF Reaches Historic Milestone

GAFGAF, North America’s largest roofing manufacturer, recently produced its one billionth square foot of EverGuard Thermoplastic Polyolefin (TPO) single ply roofing membrane. TPO roofing, which offers a combination of durability, performance, and reflectivity, is known for its energy saving properties. The EverGuard® TPO roofing line includes a wide range of products that carry ENERGY STAR® and Cool Roof Rating Council (CRRC) designations.

Reflective or ‘cool’ roofing remains a growth segment of the construction marketplace, and recent decisions by several government agencies – including the U.S. Navy – to require reflective roofing on all future projects, are expected to support the expansion of the cool roofing marketplace. The ‘greening’ of building codes, as well as the growing influence of the US Green Building Council’s LEED (Leadership in Energy & Environmental Design) green building rating system, have been additional drivers in the growth of the cool roofing marketplace.

GAF introduced the EverGuard® reflective TPO product line at about the same time that the LEED rating system program was introduced, in 1999.

Survey Finds Green Roofing Industry Up 28.5%

Green Roofs for Healthy CitiiesThe 2011 Annual Green Roof Industry Survey, sponsored by Green Roofs for Healthy Cities (GRHC), found that the green roof industry grew by 28.5 percent over the course of 2010. This is up significantly from 16 per cent growth recorded in 2009.

Green Roofs for Healthy Cities conducts an Annual Green Roof Industry Survey of its members to identify the square footage of green roofs installed each year, in each region of the country. The survey is conducted by an independent, third party consultant. The survey understates the size of the market since it is not completed by all of the companies that are actively designing and building green roofs.

The 2011 Annual Green Roof Industry Survey includes information on the growth of the green roof industry in North American cities, types of buildings where green roofs were installed, and the types of green roofs implemented.
