Using Knight Wall with Rockwool's Comfortboard 110


Knight Wall Systems today announced a collaboration with ROCKWOOL™ wherein both companies will market the industry’s first true continuous insulation (CI) rainscreen attachment system utilizing stone wool insulation rather than rigid foam, according to company president Doug Knight.
In this arrangement, COMFORTBOARD™ 110 will now be marketed as a complete rainscreen solution alongside Knight’s CI® System and HCI™ System. “There are many advantages to using stone wool insulation,” Knight said. “Fire resistance and sustainability are the first two that come to mind. But with COMFORTBOARD 110’s rigidity, we can also offer true continuous insulation, which the market prefers.”
Developed for use as an exterior continuous insulation in commercial applications,  COMFORTBOARD 110 is thermally efficient, moisture-resistant, vapor permeable and supplants other external sheathing insulations to create high-performance wall assemblies. These assemblies are effective against fire, moisture and thermal bridging, and allow for superior drying potential.
Both the Knight CI System and HCI System provide outstanding thermal performance by way of true CI (no penetrations through the insulation except fasteners), while accommodating nearly any façade or cladding system up to 20 lbs. per square foot, providing maximum versatility and durability with ease of design and installation. The CI System uses unique ¾” deep vertical box girts, called CI-Girts™; and the HCI System uses unique ¾” deep horizontal girts, called HCI Girts. Both are designed to properly disburse the façade loads over exterior stone wool board insulation, with only unique thermally isolated fasteners penetrating the thermal barrier, thus minimizing thermal bridging. Both systems’ components are produced in standard and custom lengths, in either 16- or 18-gauge Zn-Al-Mg -coated steel (standard mill silver or black PVDF coated) or stainless steel.
“We believe this new product pairing will be highly attractive to modern architects and building envelope specialists,” Knight said. “Especially LEED® projects and construction where a bulletproof sustainable design is the goal.”

Floors Without Joints

The Concrete Contractor just featured an article that reviewed 5 different techniques to reduce the amount of joints in a floor. One technique discussed by a contractor is the addition of synthetic MacroFibers, like Euclid’s TufStrand product line, to the concrete mix.

 Added any time prior to placement, Tuf-Strand macro fibers can potentially replace wire-welded mesh and smaller number re-bar in certain applications.  Usage increases overall durability, fatigue resistance and flexural toughness of concrete.

“I recommend using a reputable company like Euclid… because their engineering departments will assist with floor design. But because working with high-fiber content has a learning curve, the most important thing you can do to ensure success is to work with a good slab engineer and begin with a mock-up slab.” - Greg Fricks; The Fricks Company.

Synthetic fibers can be confusing but with Euclid Chemical’s Tuf-Strand Fiber Dosage Calculator, with just a few inputs, you can start designing your floor to have less joints. Less joints mean a cheaper and safer installation along with reduced maintenance costs over time.

Continued Good News for the Architecture Community

Architecture firm billings slowed in June but remained positive for the ninth consecutive month. AIA’s ABI score for June was 51.3 compared to 52.8 in May; remaining positive since any score over 50 represents billings growth. As a result, June’s ABI shows that demand for architecture firm services continues to improve across all sectors.

“Architects continue to see increases in demand for their services this summer, with new project work coming in at a healthy pace,” said AIA Chief Economist Kermit Baker, Hon. AIA, PhD. “However, business conditions are beginning to vary across the country. While essentially remaining flat in the Northeast and Midwest, billings jumped in the South while dropping in the West.”

Health Product Declare Labels Available for CETCO Below-Grade Waterproofing Products


CETCO has jumped on board the materials transparency bandwagon.  Through the Health Product Declare Label Collaborative, CETCO now has over 10 products listed in the HPD Repository for designers to review and consider.  

Health Product Declarations, or HPDs, disclose the materials or ingredients in our products and their associated human health effects. The HPD was created by the not-for-profit Health Product Declaration Collaborative to be the industry standard format for conveying details about product content and associated health information.  

HPD’s also help project teams to achieve the new LEED® Building product disclosure and optimization credits and the Living Building Challenge™ Materials Red List Imperative.

GBA and ILFI’s Living Product Hub Event @ Google


Got a chance to check out Google's offices in Bakery Square during the Product Transparency Seminar put on by the International Living Products Hub and the Green Building Alliance.  Seems like a lot of building owners and designers are looking much closer at the materials they select for their projects.  

Prosoco's CAT-5 air barrier has been used on the only two buildings in Pittsburgh to achieve Living Building Challenge certification: the Frick Environmental Center and the Phipps Conservatory Expansion.  The CAT-5 air barrier and accessories are "Red List Compliant" and contain no chemicals deemed harmful by the ILFI.  

Prosoco's Answer to Graffiti: Defacer Eraser


Prosoco recently released a new graffiti-removing product that is more powerful than its predecessor.

Defacer Eraser Graffiti Remover replaces the Graffiti Wipe, and is a liquid formula that more effectively eliminates graffiti.

Formulated based on contractor feedback, the product offers more effective penetration to melt away graffiti while also featuring the same ecological advantages as its other graffiti-removing products with biodegradable components.  Graffiti Remover was designed to have a shorter dwell time, allowing for faster project completion.

“Another improvement users will notice is less ghosting left on the substrate because it’s more effective at removing graffiti in general,” said Jake Boyer, leader of Prosoco’s line of masonry cleaners and protective treatments.

Graffiti Remover is designed to work with the company’s Blok-Guard anti-graffiti treatments and is water-rinsable and VOC compliant.

The product works with substrates that include terracotta, brick, concrete, terrazzo, stone, wood and metal.
