In the PHI Lab and In the Field: INTELLO Tests Tightest

Pro Clima’s INTELLO airtight system proven by Certification of the Passive House Institute and at the University of Northern British Columbia. Airtight Passive House and high-performance building enclosures help make more comfortable, healthy and energy efficient buildings. The tighter the better. It can’t be repeated enough. It follows that to make an enclosure airtight, we must use airtight materials. Ergo, the tighter […]

How Many Blower Door Fans Does It Take to Test a 26 Story Tower?

Ten? Nine? Eight? Seven? Six? Five? Four? Three? Two? If it’s the Certified Passive House at Cornell Tech? Just one. This astonishing fact is one of the many aspects of Passive House that challenge the fundamentals of how we think about construction. Many images of blower door testing in big buildings include a veritable wall of fans and […]

Building In Fall & Winter?  INTELLO Will Protect You

You’re building a high-performance, low energy building – maybe even a Passive House. What’s the Problem? You started construction in the summer, but by late Fall or Winter the finishes are being installed and the indoor relative humidity (RH) is high – reaching 90%.  You know the vapor drive is going out and the wood […]

Open joint siding? Prolonged UV exposure on WRB? The Answer is SOLITEX Fronta Quattro

SOLITEX Fronta Quattro is making waves in the high performance industry as a specialty air barrier and weather resistant barrier (WRB). What’s driving the interest? Fronta Quattro offers exceptional UV protection, making it ideal for projects with so-called “open-joint” rainscreen cladding systems in which parts of the underlying WRB are permanently exposed to the sun’s rays. Other builders […]

IDEAL Window Installation – Improving Best Practices

You bought high-performance windows, but is the install going to complement their performance or detract from it? The enclosure insulation, airtightness and moisture control should be continuous. But too often where the window frame meets the building we see breaks in insulation, air leaks and vapor traps – all setting the stage for discomfort, inefficiency and […]

Do More With Less: Your Dense Pack Netting Should Multitask

Dense pack insulation is a great way to insulate – whether it be cellulose, wood fiber (Thermofiber by GUTEX), sheeps’ wool (by Havelock wool), or fiberglass. It can guarantee gap-free thermal protection, filling all the nooks and crannies. But typical mesh-netting systems for dense pack insulation like Insulweb do one – and only one -thing: contain […]

INTELLO Responds To High Enclosure Moisture Levels – Proof Is In Collected Data

Monitoring real life assemblies is the best proof of performance. This is how we know Pro Clima products make construction as safe as possible. ECOCOR monitored a foam-free, un-vented flat roof in Maine and clearly demonstrated how elevated assembly humidity in a super-insulated assembly can safely dry inwards through INTELLO Plus. As we describe in the presentation High […]

Flanged Window Install Guide for High Performance Enclosures

Sequencing For Making Flanged Windows Airtight Flanged windows are ubiquitous in American construction.  As we push toward higher levels of enclosure performance – with increased insulation levels, airtightness and vapor control – window specifications are getting more robust too. And while it can be a relatively straightforward thing to select a better window, it isn’t so readily clear […]

CONTEGA MULTIBOND: Instantly Bonding, Airtight Joint Adhesive

Ensuring a continuous air barrier is top priority for high-performance building. Joint connections between different materials can be especially challenging points to airseal. Acrylic caulk adhesives can solve some of these problems, but is not always the fastest way to a robust connection. For example if you’re attaching two airtight, vapor-closed surfaces, such as the […]

A Smart Enclosure Starts with Smart Walls: Green High-Performance Done Right For Our Sustainable Future

For thousands of years, buildings were made with a keen regard for nature and historically, building science was intimately attuned to natural phenomenon. Then, the 20th-century builders, with giant resources of energy and rapid scientific advancements tried to conquer the vagaries of nature. Natural solutions were ignored – they made up, down, and down, up – if they felt like it. And […]

The EXTOSEAL ENCORS Primer: The Essential Sill Protection

Window Flashing That Lasts Windows are the weak link in your assembly. Along with doors, they amount to the largest holes in your envelope.  To ensure that your building is air- and water-tight, continuity between high-performance windows and your air barrier/WRB is essential. We’ve talked a lot about how to ensure air barrier continuity at […]

How to Stay Airtight When Buildings Move

Buildings move. Ensuring that your air barrier is resilient to movement is crucial to ensuring the longevity and performance of your building. Unless you’re building a structure using just one material (like superadobe), your building will consist of an array of different materials. In response to fluctuations in temperature and humidity, different materials expand and contract at […]
