How To Use The AEROFIXX Spray And Seal Airtightness Tool.
The AEROFIXX spray and seal application tool makes quick work of difficult and hard-to-reach air sealing jobs. It connects to standard compressors to easily apply liquid-applied airtight membranes anywhere from wall or ceiling surfaces to hard-to-reach gaps. The AEROFIXX is for use with VISCONN and VISCONN FIBRE sausages which is compatible with both interior and exterior application. VISCONN can be applied to CMU, masonry, and junctions, and cures into a flexible air barrier, forming seamless, durable membranes.

The teaser for an upcoming episode of Colorado Voices on Rocky Mountain PBS features a mighty fine Passive House project in Colorado Springs.
Just a short walk from Garden Of The Gods park, this picturesque location had a panelized assembly set down in just a few days by the skilled and experienced Collective Carpentry team. Architects Bronwyn Barry and Andrew Michler (featured in this interview) designed a prime example of what we could be replicating across Colorado and throughout North America as the demand for Passive House grows.
To all our Colorado-based friends: make sure to watch Colorado Voices: Building Back Better after the Marshall Fire airing June 30 at 7 p.m. on Rocky Mountain PBS.
475’s US operations will be closed on Monday, June 20th in observance of our newest Federal Holiday: Juneteenth (Emancipation Day). Our Canadian operations will have normal business hours.
From CNN Wire:
“You might see another red, white and blue flag flying today over state capitols and city buildings.
That banner with a bursting star in the middle is the Juneteenth Flag, a symbolic representation of the end of slavery in the United States.
The flag is the brainchild of activist Ben Haith, founder of the National Juneteenth Celebration Foundation (NJCF). Haith created the flag in 1997 with the help of collaborators, and Boston-based illustrator Lisa Jeanne Graf brought their vision to life.
The flag was revised in 2000 into the version we know today, according to the National Juneteenth Observation Foundation. Seven years later, the date “June 19, 1865” was added, commemorating the day that Union Army Maj. Gen. Gordon Granger rode into Galveston, Texas, and told enslaved African Americans of their emancipation.”
We are looking for a Rockies Region Product Consultant. Come work for 475 and make Passive House a reality in the Rockies! Apply at foursevenfive.com/careers
Just one week after launching our on-demand course offerings on our site, we have a new video just added. Jeremy Latriano presents High Performance Roof Daylighting.
Thermal bridging, overheating, cold air convective currents and air / water leaks can dampen or destroy the gains of free daylight and visual comfort. In this presentation Jeremy covers design considerations for roof daylighting of all types and sizes - commercial or residential, flat or pitched roof, light tube or wall-to-wall roof glass.
Find this an our other on-demand courses on our site... just take a few seconds to complete the form for access to the page.

Repost from our colleagues @lamilux_uk
Here is a remarkable example of how the LAMILUX Glass Roof PR60 system can achieve almost any bespoke shaped glass roof solution. This impressive domed rooflight, was installed at the 5* Fairmont Windsor Park Hotel which opened its doors in January this year. The hotel is described as a luxury retreat from the city with a strong focus on health and authentic wellness.
The faceted domed rooflight was supplied complete with framing detail, to fix to the faceted perimeter upstand, and consists of 64 glass panels giving an internal span of 8.5 m (28 ft).
See @lamilux_uk for full case study
We want to send a belated Valentine’s Day card to everyone involved in this project because we love it. Mixing high performance with natural insulation is where it’s at. @alpenhpp windows Pro Clima tapes and membrane from 475, a little wood and a lot of straw is just about all you need.
REPOST from our buddy Lucas
Stoked to be providing scientific guidance at another one of the amazing projects from @natural_building_works
Window detailing becomes particularly nuanced with high performance strawbale homes, but it is oh so worth the effort.
This shows the @moll_proclima system of sill tape followed with for exteriors and for interiors. The black colored Exo has a higher perm rating than the white colored SL to limit moisture loading around window frames while encouraging outward drying. Both Contega tapes are stretchy, which is critical in this case. They are also covered in a protective surface fleece that integrates well with plaster finishes.
Btw the last photo won’t make sense to most people, but I hereby dedicate it to Ray 😇🤓😂
Great example here reposted from @shedlightly -
One of the opportunities of using high performance tape for window sealing: pre-taping.
When you set them up ahead of time it’s easy to knock them out. Plus chances are your airseal will be better because you had access to all sides of the window before it went in the wall.

We're heading to the Energy Design Conference & Expo in Duluth, MN February 22-23 to present with @emuenrico of @emubldgscience on Building Passive House in Climate Zone 6 & 7. Who else will be there to brave the cold with us? Anyone in the area have a project going on they'd like to show off?
We know we can count on Tim Eian of @testudioarch - makers of the Good Energy Haus you see pictured here - and if you don't know that project, check out our blog post on it: https://foursevenfive.com/blog/good-energy-haus-as-a-case-study-and-beacon-for-sustainability/
Ever have trouble explaining the benefits of high performance building to your clients? Do yourself a solid and watch this episode of @homediagnosistv from Grace and Corbett Lunsford. They are a master class in communicating these complex issues in a way the public can understand.
As they say, airsealing is of primary importance...
“not only because it’s inexpensive, needs no maintenance, and uses no energy, but also because it has a superpower: it controls all four of the elements of home performance.”
They go on to name those 4 elements are:
- Heat Bleed
- Airflow & Pressure
- Air Quality
The term "heat bleed" alone is genius. Can we all start saying "heat bleed" in place of "thermal bridge" when talking to homeowners?! So quickly, people can see: of course I want to stop the bleeding!
The episode also features our own Johnny Rezvani @475.supply and Matt Risinger from @risingerbuild as contributing guest. Bookmark the YouTube link, watch it this weekend, catch it on PBS, and pass it on!
Link to the episode is here:
While typical constructions have a multitude of compromising penetrations, the air barrier in a high-performance construction should continue uninterrupted. Here's what we recommend to make it quick, easy, and durable:
Cable connections: KAFLEX gaskets.
Pipe/Duct connections: ROFLEX and ROFLEX SOLIDO gaskets. ROFLEX has a flexible rubber sleeve that fits around the pipe/wire and can easily accommodate any movement while maintaining an airtight seal.

We’ve been following the project from @macht.architecture - can’t wait for the next installment.
The entry way at our project. Now imagine a Japanese garden and walkway, with black shou sugi ban walls on each side and a rusted metal box above.
Yes that is a 14’ wide by 10’ tall window that is R10 Uw not just Ug. @enersigngmbh @enersign_us The windows took forever to get, but wow, we are impressed with the quality.
Before, during and after on a favorite project of ours: from barn to brewery, the @fourthpigconstruction retrofit for @goodlot.beer in Caledon, ON.
A great example of "stitch taping" to support the weight of dense-pack behind INTELLO PLUS, a great service cavity example, and just an overall fantastic retrofit, from an old barn to high performance commercial facility.
INTELLO PLUS is revolutionizing the North American construction industry. No other product provides the same level of vapor control, airtightness and resilience for your high performance projects. Our INTELLO PLUS Resource Library puts our best resources on its use into one place. So whether you're just getting started with INTELLO PLUS or are a seasoned veteran, we think you'll find something to learn.

Talk about - we have some real ProClima art here. It would give even @shaun_stamour a run for his money. This image came to us from Cillian Barrett - low-carbon builder extraordinaire in Gunnison County CO. The artist is Architect Halley Renee Anderson, who made these brilliant envelopes out of SOLITEX MENTO WRB (get it? envelopes?), which housed a card made from cork insulation. Slow clap 👏👏👏 that’s next level.
*Fighting Climate Change With Straw Panels*
This prefab project in Leyden, MA was a labor of love for the owner/architect, Michael Dobler. He recruited local GC @holdenbuilders and project management support from @buildhelm. @newframeworks provided design consultation, as well as the pre-fab straw /Gutex wall panels. What sticks out is the team’s resourceful approach to creating a home with lower energy use and carbon output.
According to New Frameworks, “While the footprint is on the smaller side, the project goals are ambitious with regards to toxicity and embodied energy of materials used along with New Frameworks' typical high-performance standards.” The team selected building materials from Fakro skylights, to Pro Clima membranes and tapes, and Gutex wood fiberboard. Outlines of the project details can be found in this spot-on piece from JLC Live.

Repost from our own @475.west.iannimmo on-site:
Had the pleasure of visiting a CLT project last week. How about that window buck?!
The CLT panels were built in Oregon by @drjohnsonclt and they also installed the self adhered waterproofing layer from @475.supply, nice work team!
Nice work with the installation by @carpentryplusinc as well!
This week the woodfibre, rigid insulation board will be installed adding to the already wood rich assembly. Lots of carbon stored up in this one!
Happy Friday - this stylish infographic was found on the wall of @alpinemodern
