Video Construction Update – Pop Project Framing


It’s been a little while since we talked about our latest cork clad babies on Blair St at the interstection of the great Philly hoods of East Kensington and Fishtown (aka “where the cool kids abide”). We’ve wrapped up framing, cladding and roofing and are racing through rough mechanicals on our way to those coveted insulation and drywall milestones.

We’ve found a new master of video production, Gregor Knell, who is doing a great job bringing a bit more professionalism to our videos. In other words, no more cheesy YouTube videos shot and edited on my iPhone. We’ve also got Mr. Jefta van Bellen of Orange Concept who designed these homes helping us out with the tour. Jefta just quit his soul sucking corporate design job and is now officially on his own. That means we can use his name, show his face and you can give him direct and proper props online and in person on the streets of Philly. He’s almost always sporting an orange accessory of some sort, so keep an eye out for this rising Dutch design star.

    Astro Turf on the roof! Sweet! How will that be applied? just glued down on the membrane or does it need a structure? Keep up the great work. I enjoy seeing how your approach is getting so refined.

    It is nice to finally see the man behind the design! I’m have so many questions about the durability of the exterior cork panels and the astro turf. Next time I’m in Philly I plan to stop by and see the Pop Project in process. Looks good.

  3. brianledder says:

    Good Question. The astro turf can just be unrolled and laid down on top of the roof. No adhesive, nails or staples. The blades of grass are woven through a pretty hefty rubber backing. We just installed some in our office and it laid flat in about 20 minutes after unrolling. Ever since our office cat has been trying to hunt in it. For what i’m not sure but she doesn’t seem to know it isn’t grass. Not sure if we have really realistic astro turf or a really dumb cat.

    Please come by and check out Pop the next time you’re in Philly, we love visitors. As for these building materials part of the reason we chose cork and astro turf was for their impressive durability. The astro turf I could believe, but to me cork was a bigger surprise. It turns out cork is made up of a honeycomb cell structure that is filled mostly with air. These cells don’t break when the cork is compressed so the air never leaves. That means if something smacks into it or the temperature changes from warm to freezing and the air compresses, the cork will rise back into into shape. And best of all cork has a natural waxy coating called “suberin” that makes it waterproof.

    Is there a cost savings using cork?

  6. brianledder says:

    Well there is and there isn’t. You could certainly find exterior cladding materials cheaper than cork, but since it doubles as insulation we were able to forgo using our usual 2″ thick rigid insulation outside of the wall cavity. That additional insulation has become standard in our homes because it prevents the thermal bridging caused by studs but with the cork we can prevent that thermal bridging and once we install it our cladding is finished as well. So we spend more on cladding but less on insulation and still get the same R-value.
