Wall Assemblies for Maximum Efficiency: How Many Layers is Too Many?

SimplexOPTIMABuilding professionals spend a lot of time dealing with production construction which has dialed in efficiencies and productivity to provide the maximum assembly for the cost per square foot.  The reality is in standard construction you build things in five or six layers. This is the standard in terms of building a wall system more efficiently and we have gotten it down to a science.  Generally a six layer home will give you a solid, energy efficient, comfortable home.

Occasionally, I work with builders on projects that remind me of possibilities beyond what is the status quo.  I recently had an opportunity to work with a builder who was building a custom home whose wall systems had 13 layers.  This wall had so much redundancy and robustness built into it that I just had to ask for a chance to visit the project and see this masterpiece being built.

This was the homeowner’s instruction: They wanted a thick wall, they wanted a silent wall, they wanted a highly efficient wall for them to own.  That’s one of the key’s to this discussion- the owner is focused on what comes afterwards- not what happened before. To achieve this goal the builder is employing a combination of traditional masonry materials and cutting edge products and systems.   

In a similar fashion, a project that CertainTeed has been involved with at the Navy Yard in Philadelphia with Penn State achieves a similar goal but in a lighter and perhaps less massive assembly – to create a highly efficient wall system that can provide comfort, improve indoor air quality, better acoustics but, and here’s the rub- to still be affordable by more typical consumers.  This was done by using a 2 x 8 construction – providing a deeper wall cavity – A Blown-in-Blanket Insulation System, Weather Resistant Barrier, a Smart Vapor Retarder and Air Barrier System, a Wallboard Solution, Rigid Insulation on exterior and Insulated Vinyl Siding. This created an R30.5 exterior wall.

In both homes, products were used to address acoustics, indoor air quality and moisture control.  Do you need 13 layers?  Probably not but the pressure is certainly going to be on what layers remain to do more than they have in the past.

Opening the Door to Better Classroom Acoustics

Slatington Elementary ClassroomLast year, I was presented with a unique opportunity to apply our building science research into a real-life application — the renovation of an elementary school in northeastern Pennsylvania. Originally built in 1973, the school was transformed from an open concept interior space into individual state-of-the-art classrooms. Superior acoustical comfort, which can contribute to improved student performance and teacher retention, was a top priority in this field study as well as an analysis of the overall indoor environment that included air quality, thermal comfort and visual comfort measurements.

Our goal was to investigate the impact of installing different, high-performing interior acoustical ceiling and gypsum wallboard system solutions in six new classrooms constructed in the third grade student wing. Acoustical tests were conducted in each classroom to determine sound absorption and interior partition sound transmission levels, as well as major sound flanking paths.

As a leading manufacturer of ceilings and wall products, our team is well versed in the myriad of product specifications and configurations for our products. However, during the testing, I had an a-ha moment of sorts regarding the doorways to the classrooms.

Specifically, I realized that even though it is well known that acoustically isolated, airtight door assemblies improve classroom acoustics when used in conjunction with high-performance gypsum board and ceiling products, these elements are often specified independently rather than a comprehensive acoustical system. This is a challenge that I have always been aware of, but seeing it so clearly in this study led us to ask: what could we do about it?

Our curiosity led us to ASSA ABLOY, the global leader in door opening solutions. Through our alliance, we’ve uncovered easily accessible solutions found in door and frame systems, to address acoustical challenges and reduce the sound reverberation that further complicates noise issues in classrooms.

We look forward to sharing more detailed findings during Greenbuild 2013 through a dedicated education session at the Saint-Gobain Learning Lab. Please join us at the session or leave us a comment below to continue the discussion.

Beware How You Finish Your Moisture and Mold Resistant Drywall

CTG_FibaTape_Mold-X10_Details_ImageWhy are you spending all your effort and resources on moisture and mold resistant drywall and then finishing it with a standard, drywall paper tape? 

That is what often happens. In high moisture areas such as bathrooms and kitchens you need to make sure that you do not erode the added value of the drywall by finishing with standard tapes. There are fiberglass mesh drywall tapes that provide the best defense against mold and moisture when used with mold-resistant treated paper and paperless drywall. 

As I have pointed out before, you want to remove the presence of food which is one the four legs needed for mold to grow:  right temperature, oxygen, moisture and food – in this case – the paper drywall tape.

Always keep in mind that everything is a system and you need to consider all aspects of the wall assembly and how you want it to perform or you may not get the outcome you were striving for.

Don’t Stop at the Surface with Moisture and Mold Damage

1316551358_254450912_4-Residential-and-commercial-Flood-Water-Damage-services-free-est-8888110187-ServicesMold Awareness Month Tip #2: When you see signs of moisture damage either on the exterior or interior you can’t just address this at the surface.  You have to keep digging until you get to dry materials.  If that means tearing out the drywall and the insulation until you get to something dry, so be it. You can’t just fix the surface because it was wet. If you have to replace materials following moisture damage consider using a mold and moisture resistant drywall and a smart vapor retarder with your insulation to add protection to your wall assembly. You will be building in more robustness to an area of your home that is apparently susceptible to moisture intrusion.

That’s from the outside too.  If you find some water damage around your window and you tear it out you can’t stop there.  Take your screwdriver or awl and probe the wood behind it to find out how far the damage goes. If you don’t correct the problem at the source and replace all the damaged materials, the chances of mold occurring in this area are very good..

So, don’t stop at the surface or just treat the symptoms.  You have to exhaust the symptoms and get to the source.

Remember, if you see moisture damage whether inside or outside the building don’t stop digging and probing until you get to dry.

Fraunhofer Institute CSE To Showcase Contemporary Sustainable Building Technologies in Real-Life Installations for Building and Design Pros

With the constant flow of new products being developed these days for the sustainable building market, it can be easy to feel like using a new product for the first time is taking a big risk. Sometimes, all you have to go on are the presentation from your manufacturer rep, the manufacturer’s reputation and, if you’re lucky, an endorsement from an industry peer who had positive results with the product. It’s not often that architects and contractors get to a see a new product they’re considering installed in a real-life application before making their final decision. The Fraunhofer Center for Sustainable Energy Systems (CSE) hopes to help change that in the very near future.

The Fraunhofer CSE is currently remodeling a 100-year-old, 50,000 square-foot warehouse in Boston to be its new headquarters, as well as an important educational outlet for building and design professionals. The retrofitted building will serve as a living laboratory for building product research and demonstration, featuring a wide range of contemporary sustainable building technologies, such as CertainTeed’s AirRenew® M2Tech® IAQ Gypsum Board.

Fraunhofer CSE will evaluate the overall performance of the products after they are incorporated into the building’s various systems and assemblies to help manufacturers give their products a true test run with building-integrated and other applied research methods. The organization also plans to showcase these products in an open-to-the-public exhibition and educational space, using innovative applications, such as smart phone and tablet apps, to call attention to energy saving and/or sustainable construction attributes. This invaluable, unprecedented service will allow everyone, from veteran architects and construction pros to students, to visualize the performance and appearance of the technologies in simulations of real-life installations and learn more about their potential.

Take AirRenew, for instance. An architect or contractor could select it for a project based on the recommendations of others, but being able to experience firsthand how its ability to perpetually scavenge formaldehyde and other VOC emissions from indoor air and trap them inside walls is a huge advantage. This feature greatly improves indoor air quality by removing that very familiar “new-home/building smell” produced by VOC content in finishes and various furnishings, as well as the headaches, nausea and other health issues that sometimes accompany it. By viewing a completed installation of this and other products and learning more about them on-site, the specifier can make more informed, confident decisions, ultimately leading to better results on projects.

Frauhofer CSE is slated to open to the public later this year. For more information, go to  cse.fraunhofer.org. For more information on AirRenew, visit http://www.certainteed.com/products/gypsum.

Building Knowledge at AIA 2013 — Expertise that Inspires

LucasAIA13Upon completion of a CEU Course at AIA 2013 on “The Future of Building Materials and Their Impact on How We Build”, Building Scientist Lucas Hamilton was asked the following question:

“What does air tightness have to do with air quality? How does the tightness influence the air inside?  It doesn’t make any sense?”

When the building envelope was leaky, we had three to four times the volume of the building being changed every hour by fresh air from outside — uncontrolled in the building envelope. Now, with tighter buildings we don’t allow that.  So, you have lost all the fresh air you had coming through the walls. That’s why it is so important. That is the influence today.

If you’re at AIA, stop by booth #2108 to continue the discussion with Lucas and our team of Building Knowledge experts. Also, feel free to add your thoughts below — comments and questions are always welcome!

AIA Convention Takes on the Mile-High City

AIA2013Welcome to Denver! The 2013 American Institute of Architects (AIA) Convention is ready to go.  Each year exhibitors look for ways to entice attendees to their booth.  This year, the Saint-Gobain family of businesses – led by CertainTeed — is taking a new approach by bringing technical and building knowledge, and solution-based insights such as indoor environmental quality, acoustics and moisture management to our booth that can have a positive impact on the design of buildings in general.

Over the past year, we have offered accredited building science courses via webinar and our online continuing education platform to builders, designers and architects.  This practice is helping to shape sustainable building.  This year we are bringing some of these courses to the AIA Convention through our Learning Lounge.  To complement this effort, the Saint-Gobain booth (2108) is staffed with technical experts across our companies who can offer building knowledge and systems expertise unequaled in the industry.

You can still talk about products, but our Building Knowledge Bar with our experts can take the conversations to a new level. You can also tweet us questions @certainteed and we can hook you up with the right expert to answer your question.

Although our courses are sold-out, we will be blogging and tweeting questions and observations that are raised in the sessions that could apply to a problem or issue you are facing. Just follow #AIA2013.

We hope to see you over the next few days at booth 2108 to share what new innovations are taking place within the Saint-Gobain family of businesses and to be your premier resource for building knowledge.

Generating Buzz for Professional Remodelers

NAHBRemodelingMonthTo help promote the benefits of working with a professional remodeler, the National Association of Home Builders (NAHB) has designated the month of May as National Home Remodeling Month.

Websites such as Pinterest or Houzz might make home remodeling projects look like a breeze, but there’s something to be said for bringing in a professional remodeler to get the best results. After all, how many of you remodelers have been called to bail out a homeowner with a botched DIY remodeling project? These sites can also be a good way to showcase you work.

Add this with compelling signs that homeowner demand for remodeling projects is on the rise and it couldn’t be a better time to proactively educate homeowners on the value of a professional remodeler.

An article from BuildingOnline reports strong growth indicators for remodeling in the first quarter of 2013. It’s reported a main contributor to this is that many homeowners now need to address projects that they had postponed for a lengthy amount of time. A recent study by the NAHB shows kitchen and bathroom projects remain the most popular remodeling jobs—both projects were up 17 percent from just a few years ago.

Whether it is the experience a professional can provide or the accurate costs and timeline, homeowners should recognize when it’s necessary to call in the experts and get the job done right the first time.

The NAHB also provides a recap of tools available to help advance your remodeling business. The materials can easily be adapted for use on an ongoing basis.  Remodelers should also research manufacturers for special programs that can help reduce costs on projects.

May might be National Home Remodeling month, but the opportunity to promote the benefits of a professional remodeler is a message that resonates 365 days a year.

A Tip for New Home Buyers – Consider What is Behind the Walls

Hybrid insulation installDuring the 2013 International Builders’ Show I had the chance to speak with a regional manager for a national builder about the challenge of helping consumers understand the features, benefits and return on investment (ROI) on the hidden features in a home. 

When a potential homeowners speaks to a builder they are usually more focused on considering upgrades that are visible to the eye than considering what’s underneath the walls of the home. What they don’t consider is how upgrading the R-value in their walls will save them money on heating and cooling over the life of the home or if they plan on selling the home in the future, how this improved performance may help them compete against homes that will be built between now and then.

The challenge that is faced by a builder as well as a solution provider is to create ways to have that very conversation with the consumer in a clear and relatively quick manner. The reality is that a builder only has so much time with a prospective buyer of a new construction and they do have a great deal of ground to cover.  It is usually easier to focus on what is visible than what is not.

During our chat, we discussed creating scenarios of building a house three different ways to maximize the efficiency of the home and how to show that to a prospective buyer.  You could have partially finished walls in the garage of a model home which show building and insulating a wall to code vs. improved materials and techniques.  You could then show various types of wallboard – yes there are varieties of wallboard that address noise reduction, mold and moisture control and volatile organic compound removal.  This could be a chance for people to actually see and understand what is usually hidden behind the finishes they have been focused on.

Truth is, potential homeowners seem more interested in talking about the aesthetics of countertop materials than increasing the efficiency of their wall systems. Why are we so comfortable being ignorant about one the most important investments of our life? I would bet that more people have researched the features and benefits of their next car in terms of gas mileage, horsepower, etc.  than researching the type of insulation and wallboard to use in their home for optimum comfort and health.

Does anybody have any ideas of how we can engage homeowners in the conversation about the energy efficiency options in homes that will lower their operating costs over the life of a home? If you are a realtor, what do you do?
