Here is how to avoid the most common problems.</em></strong></h3> <p><em>By Peter Yost</em></p> <p><img src="https://www2.buildinggreen.com/sites/buildinggreen.com/files/injection_vs_spray_foam.jpg" alt=" Henri Fennel (L); Peter Yost (R)" title=" Henri Fennel (L); Peter Yost (R)" class="image-right" height="138" width="350" />One of my first research projects when I started at the NAHB Research Center in 1993 was looking into a new insulation: Icynene. We were evaluating its performance as a spray-applied, open-cavity insulation as well as an injection foam in closed cavities. I was enamored: this seemed to be a miracle insulation that installed itself, sealing up tight even in the toughest and most complicated building cavities.</p> <p>At about the same time, the NAHB Research Center was developing an installation quality program for fiberglass batt insulation, notoriously difficult to get installed right. I scoffed; we would never need that for these foam-in-place systems!</p> <p>Twenty-plus years later, it’s clear how wrong I was. What looked as easy as point-and-shoot with the foam gun has a lot of complexity. As insulation consultant <a href="http://polyurethanefoamconsulting.com">Henri Fennell</a> recently said to me, “Properly installing site foam insulation is way more challenging than fiberglass batts. It’s partly because performance expectations are high and partly because you are actually manufacturing onsite.”</p> <p>Fennell has been injecting and spraying polyurethane foam insulation for more than 40 years. I recently got the chance to spend quite a bit of time with him at the Energy Center of Wisconsin’s <a href="http://www.betterbuildingswi.org">Better Buildings, Better Business</a> conference. Here are Fennell’s seven top tips for ensuring that manufactured foam insulation jobs—both injection and spray—get done right.</p> <p><a href="http://www2.buildinggreen.com/blogs/foam-place-insulation-7-tips-getting-injection-and-spray-foam-right" target="_blank">read more</a></p> BuildingGreen's Top Stories http://www2.buildinggreen.com/blogs/foam-place-insulation-7-tips-getting-injection-and-spray-foam-right#comments Mon, 18 Aug 2014 16:16:17 +0000 Paula Melton 20371 at http://www2.buildinggreen.com Our Energy Solutions Have All Been Found http://www2.buildinggreen.com/blogs/our-energy-solutions-have-all-been-found <div class="field field-type-text field-field-bg-blog-author-name"> <div class="field-label">Author name:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> Alex Wilson </div> </div> </div> <div class="field field-type-text field-field-bg-blog-category"> <div class="field-label">Blog Category:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> Energy Solutions </div> </div> </div> <h3 class="Standard">Not really, of course.

I thought it would be fun to write a regular column on a topic that I’ve focused so much time on over the past 35-plus years. I was pretty confident that I could come up with enough topics to write a year’s worth of columns, and I thought some of the Reformer’s readers would appreciate such a column—geeky as it might be.</p> <p class="Standard"> </p> <p><a href="http://www2.buildinggreen.com/blogs/our-energy-solutions-have-all-been-found" target="_blank">read more</a></p> Energy Solutions http://www2.buildinggreen.com/blogs/our-energy-solutions-have-all-been-found#comments Wed, 11 Jun 2014 20:16:17 +0000 Alex Wilson 19396 at http://www2.buildinggreen.com The Cover Image That Set Off a Firestorm http://www2.buildinggreen.com/blogs/cover-image-set-firestorm <div class="field field-type-text field-field-bg-blog-author-name"> <div class="field-label">Author name:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> Nadav Malin </div> </div> </div> <div class="field field-type-text field-field-bg-blog-category"> <div class="field-label">Blog Category:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> BuildingGreen's Top Stories </div> <div class="field-item even"> Living Future </div> </div> </div> <h3>The divide between the worlds of design and sustainability is persistent, but returning to core values can bridge it.</h3> <p><em>By Nadav Malin</em></p> <p>For me, the creative tension between beauty and green performance came to a head in 2006, when I began working with the staff of <a href="http://archrecord.construction.com/"><em>Architectural Record</em></a> on their new magazine: <a href="http://greensource.construction.com/Default.asp"><em>GreenSource</em></a>. (<em>GreenSource</em> is no longer a separate magazine; it’s now an insert in the products magazine SNAP. And I’m no longer involved with it.)</p> <h3>Pictures first</h3> <p>As <em>GreenSource’s</em> executive editor, I was the “technical guy” who could help make sure that we’re talking about sustainability topics in a meaningful and defensible way. I learned a tremendous amount from that team, beginning with the power of using images to tell a story. I had always been a words-and-data kind of guy, so when I saw how they developed a story by leading with the visuals, it really blew my mind. That was quite a shift from the early years of <a href="http://www2.buildinggreen.com/news"><em>Environmental Building News</em></a>, when we tended to write an article first, and illustrating it was sometimes just an afterthought.</p> <p>At <em>GreenSource</em> it went more like this: Here’s the topic, here are the images, here’s how they’ll flow, and, oh, ok, looks like we can fit in about 800 words of copy, so that’s what you get to write.</p> <p><a href="http://www2.buildinggreen.com/blogs/cover-image-set-firestorm" target="_blank">read more</a></p> BuildingGreen's Top Stories Living Future http://www2.buildinggreen.com/blogs/cover-image-set-firestorm#comments Mon, 09 Jun 2014 20:32:27 +0000 Paula Melton 19367 at http://www2.buildinggreen.com Hurricane in a Bottle: Testing Building Assemblies for Moisture Resistance http://www2.buildinggreen.com/blogs/hurricane-bottle-testing-building-assemblies-moisture-resistance <div class="field field-type-text field-field-bg-blog-author-name"> <div class="field-label">Author name:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> Alex Wilson </div> </div> </div> <div class="field field-type-text field-field-bg-blog-category"> <div class="field-label">Blog Category:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> Energy Solutions </div> <div class="field-item even"> GreenSpec Insights </div> </div> </div> <div class="field field-type-content-taxonomy field-field-blog-topics"> <div class="field-label">Green Topics:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> Moisture Management </div> </div> </div> <h3 class="Standard">State-of-the-art testing chambers show that liquid-applied barriers outperform more typical weather barriers comprised of flashing, tape, and membranes.</h3> <div><a href="https://www2.buildinggreen.com/sites/buildinggreen.com/files/Blog_Images/Alexs_blog_images/Prosoco_2110_MedRes.jpg" target="_blank"><img src="https://www2.buildinggreen.com/sites/buildinggreen.com/files/Blog_Images/Alexs_blog_images/Prosoco_2110_MedRes.jpg" /></a> <strong>BEA's building assembly test chamber in Clackamas, Oregon.</strong><br /><em>Photo Credit: Alex Wilson<br /></em></div> <p class="Standard">When I was in Portland, Oregon for the 2014&nbsp;<a href="http://www.slowlivingsummit.org/">Living Future Conference</a>&nbsp;I had an opportunity to visit a facility in nearby Clackamas where building assemblies and components can be tested for water intrusion and water vapor penetration.</p> <p class="Standard">Prosoco, a leading manufacturer of liquid-applied membranes developed the Clackamas test facility with partner company <a href="http://greenspec.buildinggreen.com/manufacturer/building-envelope-innovations-llc/10689">Building Envelope Innovations</a> (BEI).</p> <p class="Standard"><strong>A Cat 5 hurricane in a closed chamber</strong></p> <p><a href="http://www2.buildinggreen.com/blogs/hurricane-bottle-testing-building-assemblies-moisture-resistance" target="_blank">read more</a></p> Energy Solutions GreenSpec Insights http://www2.buildinggreen.com/blogs/hurricane-bottle-testing-building-assemblies-moisture-resistance#comments Thu, 05 Jun 2014 03:09:22 +0000 Alex Wilson 19316 at http://www2.buildinggreen.com
