Positive Responses to Negative Statements About PVC: Part 2

Negative Statement: “Chlorine is harmful to humans and should be banned. Therefore, PVC products should be banned since they are made using chlorine.”

The use of chlorine to purify drinking water has done more to improve the health of the human race than any other technological change in history. Seventy-five percent of life-saving medicines are based on chlorine chemistry. Chlorine is one of the components of vinyl that helps make it fire resistant. At number 17 on the Periodic Table of Elements, chlorine is one of the most abundant elements on the planet. It is not possible to eliminate an element such as chlorine that occurs naturally and so abundantly. And why would one want to eliminate something that has done so much to further the human race?

Patrick Moore, a co-founder of Greenpeace, left the organization after 15 years because the environmental movement had abandoned science and logic in favor of emotion and sensationalism. Greenpeace calls vinyl the ‘poison plastic,” but Moore states that because of vinyl’s ease of maintenance and its ability to incorporate anti-microbial properties it is critical in fighting germs in hospitals.

Belief in junk science can lead to unintended consequences. In late 2000, Washington, D.C. switched from disinfecting drinking water with chlorine to disinfecting with chloramines, a combination of chlorine and ammonia. Suddenly, lead levels began to rise. It was determined that the ammonia made the water more corrosive, which increased the amount of lead leaching from the pipes into the water.

Another example of negative consequences caused by junk science: Peru eliminated chlorine from its drinking water in the early 1990’s. An outbreak of cholera (1 million cases resulting in 10,000 deaths) was exacerbated by this move and Peruvian officials have since returned to using chlorine for disinfection.

PVC manufacturing in the United States is tightly controlled and very safe. Once chlorine is processed into vinyl, it is chemically locked into the product more tightly than it is in salt, and no chlorine is emitted from the finished product. This is true for roofing systems and other building components that use PVC.

Next Month’s Negative Statement: “The movie Blue Vinyl gives real life examples that prove that PVCs are bad and people have been harmed by working or living around PVC factories.”

This year’s National Sales Seminar is being held in Dayton Beach, Florida, January 25 – 27, 2009.

The True Price Of High Performance

Oxymoron, n: a combination of contradictory words (such as sustainability costs more)

Contrary to popular wisdom, when it comes to the building and construction industry, profitability and sustainability go hand-in-hand. In fact, if a new building component doesn’t contribute to business profitability, it is not sustainable.

Sustainability, or high performance design, is often equated with “green design.” However, high performance design is about making financially smart building choices, not just being “green.” Consumers typically will not pay for something that is green unless there’s a financial benefit as well. Sustainability is good business sense first – green comes with it.

High performance building projects address issues related to the design, construction, maintenance, rehabilitation and eventual demolition of a building with an emphasis throughout the building’s lifecycle on using resources efficiently and preserving the global environment.

The profitability of high performance design must be considered for the entire life-cycle of a building, not simply the initial cost of construction. Typically, a roofing system with a low initial cost is a teaser that fails to consider all of the costs associated with the roof over its useful life. A long-lasting, high-performance system delivers a lower cost of ownership spread out over a longer period of time, requiring fewer repeated expenses related to maintenance, repair, and replacement. Plus, benefits such as energy savings can reduce life-cycle costs even further.

Recently, a contractor called to say that he was going to change his approach to selling roofing after a building owner said that the Duro-Last roof was the least expensive roof he had ever bought. It seems that the building owner was a banker who calculated that the Duro-Last roof was costing him 30% less per year in maintenance, repairs and frequent replacements than the modified bitumen roofs that he had always used before.

A smart investment because it costs less over its life span, a high performance roofing system is the ideal choice for sustainable facilities.

Project of the Month: Beacon House, Marquette, Michigan

Duro-Last Roofing®, Inc. recently donated over 4,500 square feet of roofing membrane to Beacon House in Marquette, Michigan. Beacon House is an independent organization that provides lodging and other support services in a “home-like” environment for patients, their caregivers, and family members traveling to Marquette County for medical treatment.

Beacon House was contacted by Trevor Wagester, Associate Sales Representative for Duro-Last, when he heard about what the Beacon House is calling their “Extreme Makeover” campaign, and their need for a new roof. “Beacon House is sustained solely by the generosity of businesses, foundations, and guest donations,” he said. “We hope that others will follow in helping Beacon House with the many improvements that they need.”

Four roofing contractors in Michigan came together to help with the cause. Local Roofing of L’Anse, Lake State Roofing, Inc. of Iron Mountain, and Great Lakes Roofing of Sault Sainte Marie all donated their time to help install the roof. Pellow Roofing and Sales of Marquette coordinated the ordering of the roof, removed the rock ballast, and provided the crane as well as the labor for the installation and addition roofing materials. All of the roof installers worked together as a team with the single goal of getting the roof installed.

“Our prayers have literally been answered,” said Marcy Griffen, Executive Director for Beacon House. “We will no longer need to worry about our roof leaking when the big storms of the Upper Peninsula roll in. We are so grateful to Duro-Last and all the roofing companies coming together to help us.”

The highly-reflective white membrane will deliver energy cost savings to the Beacon House as well as provide the facility with a virtually maintenance-free, leak-proof roofing system. Backed by a 15-year full warranty, the Beacon House doesn’t have to worry about anything but caring for patients and their family members.

What Attributes Of A Duro-Last® Roof Can Help With LEED® Ratings?

The U.S. Green Building Council has developed the Leadership in Energy and Environmental Design (LEED) Rating System to help in the design and construction of buildings that have minimum negative impact on occupants and the environment. LEED provides standards for choosing products based on environmental attributes. LEED does not certify materials or products.

So what are the attributes of a Duro-Last roof that can help with soon-to-be enacted changes to LEED-NC ratings?



ENERGY STAR® labeled product with a Solar Reflectance Index equal to or greater than 78 (Duro-Last is 110) Sustainable Sites Credits 7.2
Exceeds ASHRAE Standard 90.1-2007 Energy & Atmosphere Credit 1
Extend the lifecycle of an existing structure, reduce the load on air conditioning units, and reduce a buildings impact on the environment. Materials & Resources Credits 1.1 & 1.2
Custom prefabrication eliminates waste at the jobsite, scrap and trim are 100% recyclable, with four manufacturing facilities requiring less than 500 miles of shipping. Materials & Resources Credits 2.1 – 2.2, 4.1 – 4.2, 5.1 – 5.2
Two-way vent system keeps negative air pressures and condensation in check, high reflectivity keeps building cooler. Indoor Environmental Quality Credits 2 and 7.1

All in all, Duro-Last Cool Zone® can help with obtaining 13 – 31 points toward the minimum LEED certification of 40 – 49 points.

Positive Responses to Negative Statements About PVC: Part 1

Recently there have been renewed criticisms of vinyl building products by some activists who have traditionally taken an anti-PVC stand. In this post and others to follow we’ll address some of these negative statements with facts about the use of vinyl building materials.

Statement: “The USGBC report concluded that PVCs are bad.”

The facts: This statement is a reaction to The US Green Building Council’s Technical and Scientific Advisory Committee‘s (TSAC) February 2007 report: Assessment of the Technical Basis for a PVC-Related Materials Credit for PVC.

In reality, the TSAC PVC Task Group reaffirmed their conclusions from the earlier draft report that PVC should not be considered for a negative credit in the LEED rating system. According to USGBC’s president, “TSAC’s report identified critical gaps in our understanding of how materials impact our health and environment.” TSAC’s conclusions on PVC’s environmental impact state that awarding a LEED credit for avoiding PVC’s would be a “blunt instrument” that could “steer decision makers toward using materials that are worse on most environmental impacts.”

The report was not intended to determine which alternative is “best” in any application, only whether PVC is consistently among the worst alternatives. Only four categories of products were reviewed in the study: siding, pipe, resilient flooring, and window frames. To generalize any findings and apply them to all vinyl products would be a misrepresentation of the information. Human health analysis focused on what may happen if end-of-life PVC burns accidentally in landfills or backyard. But it did not consider the same potential with other materials compared in the analysis. By its own admission, the report states that “Health impacts from exposure to dioxin emissions from accidental landfill fires and barrel burning of PVC and other materials are highly uncertain for a variety of reasons.”

The upshot: When considered over their entire lifespan, products made of PVC are no worse and may be better than alternatives that have not been tested.

In our next installment, we’ll look at this statement: PVC products are made using chlorine and chlorine is bad. Environmentalists are right to want to eliminate chlorine from the face of the earth.
