What You Might Not Know About PVC!

                         What is PVC?

 

pvc

 

Poly Vinyl Chloride, is a thermoplastic material that is heat welded, which makes it more resistant to leaks. It is a highly reflective and durable single ply membrane. Its ease of installation and heat welded seams makes it a common choice for flat roofing.  It can be installed either mechanically fastened or fully adhered. It is designed to be flexible and conform to the movement of the roof. They maintain their flexibly because its formula contains plasticizers as well as salt that is derived from the chlorine used in its production.

It is available in rolls that that are larger than most other roofing systems, in return it has less seams which can mean less chance of failure. PVC is known for its lack of water permeability which can decrease incidents of water ponding. PVC is available in many colors, most commonly used is white. This makes it highly reflective and considered a “cool roof” which can provide significant savings in energy costs and have less of an impact on our environment.

Seems like PVC would be the top choice for your flat roofing system right? Although PVC has been the major building material in the last 40 years, and now totals more than 30 million tons per year, it poses serious environmental and human health hazards. Listed below are main components of PVC and their impact on our environment as well as human health:

  • PVC and Chlorine: Vinyl is the largest use of chlorine gas in the world, PVC is  the largest production by volume of organochlorine which is toxic to humans, animals and our enviornment.  Formation of organocholorine begins with the production of chlorine gas which is used in the making of PVC.The other by product of the production and lifecycle of PVC are dioxins, formed when chlorine gas is burned in the formation of PVC. Dioxins are global pollutants and is the most potent synthetic carcinogen tested, and is a known human carcinogen.

 

  • Plasticizers: When PVC is in its purest form it is very brittle, to make it flexible for roofing materials they add plasticizers, the most common used plasticizer in the formation of PVC is known as phthalates, which pose serious health and environmental hazards. They are used due to their plasticizing performance and low cost.

 

  • Lead and stabilizers: Because PVC naturally decomposes over time, metal stabilizes are added to the vinyl to extend its life for construction purposes. One of the most commonly used stabilizer in PVC production is lead, and because metal does not degrade into the environment it has become a global pollutant.

 

Chase Construction’s Commitment to Environmental Sustainability

Not only are the ingredients and bi products of PVC environmentally hazardous, chlorine production used in the making of PVC is one of the worlds largest energy-intensive processes. Not only that but PVC is rarely recycled because the compounds in vinyl do not decompose. Because of its environmental impact almost all European Union nations have restrictions on the use of PVC.

The Uncool Effects of Cool Roofing

Cool roofing may not be as “cool” as we think!

COOL ROOFING

 

Beginning in the 1980’s research on the benefits of cool roofs was conducted by the Department of Energy in hopes to find a way to save on energy costs and reduce our carbon footprint on the environment. The widely accepted belief that has developed from this research is that white roofs are the most environmentally friendly and energy efficient choice when it comes to roofing. This “cool roof” solution has become a quick and low cost solution in hopes to reduce carbon emission which is known to effect climate change. However, it has been said that cool roofs are not a “quick fix” to save on energy costs and that in certain climates they may actually increase energy consumption.

Due to the belief that reflective roofing is the easiest solution to lowering energy costs and reversing the effects of climate change, there has not been much consideration of geographic location . Although roofing professionals know that depending on geographic location and weather conditions there is a roofing system required for each roof.

Reflective, or what is known as “cool roofs” have been proven to reduce air conditioning costs during hot summer months, which in return provides home and building owners a great deal on energy savings. However, take into consideration colder, northern climates where people must spend more money heating a building rather than cooling them, the cool roof solution may not be a smart choice for them. In return, a reflective roof may actually increase carbon emissions due to increased energy consumption.

 

Effects of Cool Roofing in Cool Climates

Aside from inefficiency, reflecting roofing systems can have negative consequences in cool climates. The roof cover only concept regarding white reflective roofing implements only changing the color of the roof top from black to white. However, this concept ignores the components that are underneath the surface and how they are effected by the transition from black to white. One issue that can arise from cool roofs being installed in cooler climates is condensation. During the summer surfaces stay cooler, however when temperatures are colder the surface remains cooler for a longer period of time. In return it will fall below the dew point and remain there longer compared to darker membranes, which leads to condensation formation.

Condensation is one of the most potentially hazardous consequences of cool roofing. How does condensation occur? Warm air begins to rise toward the roof when temperatures outside drop. With no air or vapor retarder the warm air that rises makes contact with a surface that has dropped below the dew point and forms condensation.

 

CONDENSATION

 

 

 

 

 

 

 

Warning Signs

There are several signs that can reveal the presence of condensation. One way to tell is when you walk on top of the roof, if there is a crackling noise below your feet it is a dead give away that there is frozen moisture in your roofing system. You can come across this situation typically when a roofing system is insulated with a single layer opposed to multiple layers. When multiple layers of insulation are implemented in a roofing system, the joints end up staggered which in turn makes warm, moist air to reach the underside of the roof membrane. Therefore, using multiple layers to insulate your roof, although not foolproof, can help to decrease the level of moisture collecting beneath a roof membrane. Another issue that can arise from the use of a single layer of insulation is that moisture can free between the insulation joints, which causes it to expand as it begins to freeze and pushes the edges of insulation boards apart. Moisture will also lead to the insulation warping. Therefore, when frozen inflation experiences warmer temperatures, the frozen moisture will begin to drip inside the building.  Another unfortunate result of condensation is adhesion loss. When moisture accumulates and does not have the opportunity to dry, insulation facers can weaken, and therefore the membrane can detach from the insulation which causes reduced wind uplift resistance.

 

How to avoid condensation

When choosing  a roofing membrane color make sure you take into consideration the climate in which the roof will be installed. Typically in northern and colder climates, a dark membrane is used, where in warmer southern climates, a white more reflective membrane is used. However, if you are to implement a reflective membrane in a cooler climate, one way to try and avoid condensation is to use a continuos air or vapor retarder, as well as using the multi layer insulation method.

Recycle Building

Although reflective roofs are installed with good intentions, in hopes to reduced energy costs as well as our carbon footprint. Do not forget that these benefits are typically seen in warmer, southern climates. Therefore, if you are going to install reflective roofs in cooler climates make sure you implement certain design modifications to help reduce the presence of condensation, because when installed cautiously and correctly, cool roofs can perform quite well in cooler climates!

SMOG-EATING Tile: Protecting Your Health and Our Environment!

 

SMOG-EATING Tile: BORALPURE™ Technology

 

green-banner1

 

 

 

 

 

 

Living in the Pacific Northwest you hear many people complaining about the rain, cloudy skies, and overall our pretty bipolar weather. However, you don’t hear many pacific northwesters complaining about “smog” like you would in say, Los Angeles. However, air pollution is all around us and air quality affects the publics health, our environment and overall our quality of life. It is estimated that 2.4 million people die annually world wide due to causes attributed to air population. (World Health Organization)

 

An Impeccable Solution

 We all want to do our part to protect the environment and safeguard our health from negative effects of our air quality. That is why BORAL Roofing has designed a clay tile with just that purpose in mind.

BoralPure™ SMOG-EATING tile is the first tile in sustainable concrete roofing created that is designed to reduce the formation of smog. This revolutionary tile can be installed on both residential and commercial roofing projects. It is the only concrete tile roofing option in the U.S. that extenuates air pollution, all in the effort to protect our environment.

In the course of a year, 2,000 square feet of the SMOG-EATING Tile reduces the same amount of nitrogen oxide (which is a strong component of smog) that is produced by one car driving up to 10,800 miles, thus causing BoralPure™ SMOG-EATING Tile to be a critical key in solving the concern of air pollution and the health issues it causes.

Protect our environment, your home and your health!

The way in which this smog eating tile works is that there is a catalyst that is embedded into the upper portion of the roof tile. When it is exposed to sunlight the oxidation process speeds up and in return reduces nitrogen oxide. Nitrogen oxide can be produced during the burning of fossil fuels which is mainly caused by the driving vehicles. The SMOG-EATING Tile takes substances that are harmful to us and to our environment, and turns them into safe ones therefore protecting our quality of air. If you want to ensure your home is protected from environmental impacts but protects our environment at the same time, BORALPURE™ Smog Eating Tile is the roofing system for you!
