ILI Publishes New Declare Labels

Industrial Louvers, Inc. (ILI) is proud to announce the release of two Declare labels.  One for Storm Performance Louvers that is Red List Compliant and one for Custom Sunshades that is Red List Free, both with a Fluropon Pure Kynar Finish.  Declare is a vital tool for our ongoing transparency efforts and is helping us lead our industry toward sustainability and transparency.

The International Living Future Institute’s (ILFI’s) Declare program is a transparency initiative through which manufacturers and designers present to consumers the answers to three simple, but significant, questions. A Declare label states where a product comes from, what materials go into its production, and what happens at the end of its lifecycle. Declare’s nutrition-label format makes complex lifecycle and chemical information accessible by allowing consumers to easily distinguish products that align with their values. Declare is a component of ILFI’s Just, Living Product, and Living Building Challenges, and is consistent with LEED v4 requirements.

Meeting the Code with Acrylic Dome Skylights

Wasco SkylightsWasco Products, Inc. first introduced the acrylic dome skylight in 1949. For 65 years it has been an industry staple for bringing daylighting through a roof into a building. The original dome skylight, now made by many different manufactures, does not meet the 2009 and 2012 editions of the IECC.

NFRC CertifiedWasco, the pioneer of dome skylights, has applied advancements in acrylic and aerogel technologies to reengineer the dome skylight. The EcoSky3 unit skylight meets and exceeds the requirements of the 2009 and 2012 IECC Prescriptive Fenestration Requirements for every climate zone in the United States. EcoSky3 also offers infrared blockers, glare free daylighting, fall protection with impact modified acrylic, and is certified by the NFRC.

Georgia Pacific DensDeck Prime

 

Incorporating a roof cover board into a roofing system has become standard practice when designing a roof that can last well beyond the roof warrantee period. For a cover board to be effective it needs to have the impact resistance that can withstand foot traffic and hail. It also needs to have good tensile strength to enhance wind uplift ratings, and prevent fastener rocking during high winds. Class A fire rating, mold resistance, and improved sound buffering are all key elements to a high performing cover board.  Not all cover boards on the market can meet these demands.

 

 

Georgia Pacific DensDeck Prime does, and is the leader in the roof cover board market with billions of square feet of undercover. Other cover boards such as high density polyisocyanurate ISO and Gypsum Fiber roof board fall way short in delivering the same performance.  Get the facts and see the comparison tech notes DensDeck Prime vs Gypsum Fiber Roof Board and DensDeck Prime vs High Density Polyisocyanurate.

Complying with the new commercial energy code for continuous insulation and attaching heavy exterior cladding

One of the most frequently asked questions we get is how to meet the requirement for continuous insulation as defined by the commercial energy code (..."Insulation that is continuous across all structural members without any thermal bridges"...) and hang various types of heavy cladding over the insulation. What we see being used are a lot of metal Z channels as the means of attaching the siding, which comes short of meeting the requirement of the code, and in fact acts as thermal radiators for energy loss.


Knight Wall has developed an attachment system engineered to attach heavy cladding over insulation which complies to the energy code, and eliminates the short circuits. The same Knight wall system can be used for attaching terracotta, metal panels, cement board, wood siding, stucco, stone veneer, and thin brick panels. For more information please go to www.knightwallsystems.com.


Air barrier Connection Details for Windows, Curtain walls and Storefront

Two of the most frequently asked questions we receive from the architectural community is how to connect an air barrier to windows, curtain wall and store front; and where is the proper placement of the thermal break. I am happy to report that with EFCO's help we now have suggested details with some new extrusions that address these issues.

Sustainable Single Ply Roofing Update

Boston MA, Sika Sarnafil, Dow Chemical, and Georgia Pacific announce in New England a 20/40 year Renewable Single Ply Roofing System, The EcoSmart Roof. This system is designed to be sustainable and a dramatic move away from the typical disposable single ply roofing systems.

Sika Sarnafil will issue a 20 year water tight warrantee on their Sarnafil single ply membrane, along with a certificate of recyclability. Sarnafil membrane can now be recycled after its life back at their plant in Canton MA. Please see the Marriott Long Wharf project profile for more detail.

Dow Chemical will issue a 40 year reuse warrantee on Styrofoam Deck Mate roof insulation. Deck Mate's high R-value, high compressive strength and its resistance to moisture makes it permanent roof insulation. This insulation has the same performance as the cavity wall and below grade permanent building insulation. Deck Mate is also fire approved by every building code in the United States for direct application to metal deck.

Georgia-Pacific Dens Deck cover board protects the insulation against mechanical and roof traffic damage during the life of the roof, as well as when it is time to reroof. Dens Deck has a high compressive strength, is mold resistant, and is the only cover product with a moisture resistant treated gypsum core.

This singly ply roof system is environmentally responsible and its goal is to eliminate roofing material from entering the waste stream in the future. Most importantly this system costs the same or is as competitive as the typical disposable single ply roofing systems now being specified.

Ref- What is the expected savings of an effective air barrier on a commercial building?

The use of air barriers on commercial buildings is becoming the standard building design, as building codes are requiring them and architects recognize all their benefits. The question we have been asked repeatedly over the past four years, concerns the amount of energy savings that a commercial building should realize by an effective air barrier. The National Institute of Standards and Technology (NIST) has just completed a comprehensive study on the subject. They found that the use of an effective air barrier like Carlisle Barriseal or Carlisle 705 can achieve a savings in energy of more then 36% in cold climates. To view the complete study refer to the link below.

LEED™ Credits for Extruded Polystyrene and Polyisocyanurate Insulation

The U. S. Green Building Council has developed a system to rate the environmental designs of buildings. The Leadership in Energy and Environmental Design (LEEDTM) rating system allows design professionals to accumulate credits based on meeting certain criteria. For information on the number of credits for rigid insulation please see the insulation technical note below.

LEEDTM Rating for Rigid Insulation


Best Practice Brick And Block

To effectively install rigid insulation in a brick and block cavity wall with or without an air barrier there needs to be a "SYSTEM". The system must enable the wall to be put together easily with structurally sound results. All too often insulation is friction fit between eye ties, or adhesive is relied on as the long term securement of the insulation. In many of these installations mortar droppings on the block and eye ties do not allow the insulation to lay flat and tight against the block. If the insulation is not flat against the block and the insulations joints are not tight, a chimney effect, or convective loop of cold air will flow behind the insulation. This can significantly reduce the effectiveness of the insulation.

To prevent air movement behind the insulation, a mechanical brick tie that also secures the insulation to the block should be used. The type of insulation should be 4 x 8 extruded polystyrene that has shiplap edges. This system of attachment along with large sheets of shiplap insulation will deliver the designed R-value to the wall.

When an air barrier is applied to a block wall with eye ties, there is a real problem achieving an air tight seal around the ties, and keeping the block clean of mortar. The use of a Positie brick tie eliminates eye ties and the problems assoiated with applying an air barrier. The Positie system enables the mortar joints to be struck flush, and the block work kept clean for a seamless air tight application of the air barrier.

The following are best practice photos and descriptions for installing rigid insulation and brick ties over an air barrier system.

Carlisle Barriseal roll grade is simple to install and a very effective air barrier on block back up. Spillane Waterproofing is rolling on two heavy coats to achieve 40 mil thickness. They prefer roll on air barriers because they can work on small areas of the building at a time. This enables them to keep up with the construction progress. In addition there is no investment in spray equipment and no need to protect the building and the surrounding areas from over spray.

As can be seen from the photos, the block needs to be free of voids and tooled flush, and all the openings and transitions need to be sealed with Carlisle 705 sheet goods.

Griffolyn T-65 Vapor Barrier is installed on the prepared soil. Griffolyn T-65 is a high density polyethylene with a cord reinforcement. This product resists punctures and tears that can occur during installation, and has a lower permeability than standard 6 mil polyethylene.

Dow 2 inch STYROFOAM extruded polystyrene is being used as the slab insulation. As seen in the photos, the compressive strength of 2 inch STYROFOAM can easily handle the construction traffic. Notice also that the insulation on the inside of the foundation wall is brought to the top of the interior slab to meet the MA code requirement of continuous insulation. The MA requirement of continuous insulation under the slab is to prevent mold from occurring between the slab and floor covering in the summer months.


Daylighting Studies For School And Retail

A study that looks at the effects of daylighting on human performance was recently conducted by Heschong Mahone Group (HMG), a nationally recognized building energy efficiently consulting firm. The study focused on skylighting and daylighting in schools and retail stores. The results in schools found that test scores of students were 7% to 18% higher than those students without natural lighting. For retail, those stores with skylights showed significantly higher sales then those without skylights.

Air Barrier Consultant: Thompson & Lichtner Company, Inc., Cambridge MA
Air Barrier Contractor: Premier Caulking, Londonderry NH

The new dorms now under construction at the University of Massachusetts Dartmouth Campus are incorporating Design "G" as the air barrier wall system.

Design "G" is Barriseal from Carlisle, a liquid applied air barrier that can be sprayed or rolled on the substrate. Block back-up walls are the ideal surface for liquid systems. Openings are sealed with Carlisle 705, 40 mil sheet membrane and mastic, and then over-sprayed with Barriseal. Barriseal is sprayed on either 40 mil, 60 mil or thicker, depending on the job requirements.

To view details and specifications of Design "G", go to the wall section of our web site.


For steel studs and DENS-GLASS, Design "A" has proven to be the most economical and effective way to build an air barrier into this wall type. Design "A" incorporates Carlisle 705, 40 mil peel and stick membrane over DENS-GLASS. Incorporating a brick tie such as Posi-tie allows the use of 4x8 shiplap extruded polystyrene Dow Cavitymate STYROFOAM. The brick tie self-seals as it goes through the Carlisle 705 and becomes the permanent attachment for the insulation as well as the brick. Utilizing a 4x8 shiplap board helps eliminate thermal bridges, which is a requirement in the MA Energy Code Section 1302.0, Definitions of Continuous Insulation. In the field the air barrier installers have been using Glass-Grip from Carlisle to adhere the insulation to the membrane. This is being done immediately after the membrane is installed, so it can be protected from construction site damage. To view a job profile of this, please refer to the Tufts Jaharis Center news item, below, dated September 21, 2001.

Roofing

Gale Associates Inc. building envelope consultants, are now constructing their new corporate headquarters building in Weymouth, MA.. Jon Lindberg, P.E., RRC Principal of Gale Associates Inc., designed a single ply roof assembly that incorporates both extruded polystyrene Dow Deck-Mate insulation, and a cover board GP Dens-Deck Primed for their headquarters building. Mr. Lindberg recommends extruded polystyrene roof insulation for the following reasons:

  1. It has superior resistance to moisture over any other roof insulation.
  2. Stable R-Value
  3. Reusability in the future when reroofing is required

He feels it is particularly important now to use extruded polystyrene in a roof assembly with the new MA energy code chapter 13 requirement of a vapor retarder on the deck. Roof assemblies with vapor retarders can trap moisture should leaks occur. Foam roof insulations such as Poly Iso have a very poor resistance to moisture. The closed cell nature of extruded polystyrene enables the insulation to stay dry when moisture becomes trapped in roof systems.

Three years ago the National Roofing Contractors Association (NRCA) recommended the use of cover boards in roof assemblies. Mr. Lindberg and Gale Associates Inc. have been specifying cover boards for over 25 years. GP Dens-Deck Primed has become their choice for cover boards under reflective or light colored membranes because:

  1. It has a high impact surface, and withstands roof traffic that otherwise could lead to underlayment deterioration and roof delamination.
  2. No other cover board has the moisture resistance properties of Den-Deck.
  3. Dens-Deck Primed requires less adhesive in fully adhered single ply roofs.

Details for this roof assembly can be found on our website in the roofing section entitle Single Ply Roofs.

This enables the board to stay dry during the construction process, and allows the air barrier membrane, or air barrier tape to be applied anytime. Regular paper face gypsum sheeting does get wet during the construction process and air barrier membranes and tape cannot be applied until the sheeting is dry. This is one reason why Dens-Glass is the best choice for sheeting exterior surfaces that are going to be covered with air barrier membrane or tape.

Carlisle 705 was selected as the air and water barrier over Dens-Glass sheeting. This product is a 40ml peel and stick membrane that adheres well to Dens-Glass when primed according to Carlisle's recommendations.
