Exterior: Wall Applications

 Exterior Application:

PL Premium Adhesive/Glue Application;

Insulating Concrete Exterior WallsOn the back of the panel, apply a 3/8″ bead of PL Premium 3X along the dove-tailed ribbing of each InSoFast stud. Rougher or uneven surfaces may require a thicker bead. Press panels firmly into place against the wall. On windy days, the panels may need supplemental bracing or mechanical attachment to secure the panels until the adhesive has set.

    1. Using adhesive is the preferred method over masonry, brick, stucco, or concrete surfaces where mechanical fastening would be difficult.
      • Adhesive application over wall framing that is air and water tight (ZIP Wall, HardiBacker, Durock, and PermaBase) is also acceptable.
    2. It is best practice to make sure the substrate must be clean, dry and free of frost, grease, dust and other contaminants before proceeding.
      • If cleaning is required use a masonry cleaner such as Trisodium Phosphate (TSP) mixed in warm water, avoid cleaners that have surfactants.
      • Surfactants reduces water surface tension, thereby increasing its spreading and wetting properties. This is bad when trying to keep water out of a wall system.
    3. The wall must be structurally sound before installing InSoFast (or anything for that matter), check for levelness or plumb. InSoFast panels can bridge over minor wall imperfections the interlocking design helps self-level to an extent. 
    4. Adhesive Testing: If you are unsure about the conditions of your walls, we recommend performing an adhesive test.
      • Find a scrap 2×4 measuring at least 6 inches long and run a 3/8-inch bead of adhesive along it's 1 1/2" edge. Press the “test block” against the wall use mechanical support for 24 hours while the adhesive cures. You’ll need to wait 24-48 hours for the adhesive to cure, but keep in mind that PL Premium takes 14 days to reach it’s full strength.
      • When the curing time has passed you are ready to test the strength of the bond. Try to pry the test board off the wall. If you can manage to pull it off with your hands, you will need to mechanically fasten the panels to the wall.

1. Find the Ribs on the studs.


Insulating Concrete Exterior Walls

Make sure you are gluing the ribbed side of the studs. The front side is of the panel a smooth black stud is exposed or is covered with 1/2" of foam. Quick Tip: You can speed up your installation by pre-stacking the panels with rib-side facing up, ready for adhesive.

2. Apply Adhesive

Glue the Stud
Run a ⅜-in bead of adhesive along all 3 studs. If you are placing the panel on the edge of a wall or in a corner, run a bead directly on the foam at that edge (see: dashed line). This will ensure a solid-backed attachment. Again, it is only necessary at corners and anywhere you cut a panel to fit around openings.

3. Press in Place

Press in place
Check that your panel is tongue-side up, with the rib-side facing the wall and that any interlocking edges meet. Press firmly against your wall. Don’t be alarmed if it feels a little spongy at first. PL Premium takes about 20 minutes to set and 24 hours to cure. It can form a “liquid shim” spanning gaps of up to ⅜-in and effectively tighten up small irregularities in a wall’s surface. On walls that are subject to peeling or flaking paint, it is important to supplement the installation of InSoFast panels with mechanical fasteners such as Tapcon® screws or Perma‐Grip nails.

Alternate Method using Masonry Adhesives;

Masonry Adhesives

Masonry adhesives are used over masonry brick or block walls with liquid applied WRB, a 3/4" bead of adhesive is applied to the dovetailed ribs on the back of the panels. Most often applied with a mortar pointing bag.

Mechanical Attachment screws and fastening Patterns;

Screw/Nail Attachment Pattern


Using the indicator markings on the panel, screws are placed 12” o.c. along the InSoFast studs per code report. InSoFast panels are generally screwed in place, however, you may opt to use nail guns to install the panels and siding provided the temperature is above 60° F for the stud to accept nails. It is up to the contractor and/or building official to determine the suitability for the nails in regard to use, length, and spacing.

For 16” O.C. Framing


InSoFast studs are 16” o.c. Install the first panel so that the built-in studs line up with and attach to the wall’s studs.

Nailing the panels to the wall when the nail has a minimum penetration into the structural framing stud, use screws if attaching to just the structural sheathing. 

For 24” O.C. Framing


Attaching to 24” o.c. framing requires a structural sheathing you can screw to, such as OSB, plywood, or SIPs and requires the use of 8” o.c. indicator marks. The number of screws is dependent on wind load requirements.

Fastening Guidelines;


If you choose to mechanically attach InSoFast panels to concrete or masonry walls, screws are to be placed 12″ o.c. along the InSoFast studs. Powder actuated tools are not recommended.

  • Both panels InSoFast EX 2.5 and InSoFast UX 2.0 can be directly attached to most exterior surfaces as a continuous insulation barrier for the exterior envelope of a building. Fasteners design load should be resist the shear and wind loading resistance when used to secure the InSoFast panels to concrete, wood, or steel framing systems.
  • Design Approvals: Where required by code or design professionals attaching the InSoFast panels and the suggested fastening methods identified may exceed 12″ o.c. should be prepared and engineered by a design professional licensed to do so.
  • Design Loads: The design loads required by the local building code authorities shall not exceed the recommendations outlined in this guideline.
  • Allowable Loads: The applied dead and negative wind loads should not exceed the tables outlined in this guideline for each of the different fastening systems for concrete, wood, or steel framing methods. The required fastener spacing is determined by the different fastener manufacture’s test reports for shear and wind
    loading and not by InSoFast, LLC.

Installing Exterior Finishes - Cold Weather Installation;

Cold Weather Installation Tips for finishes application;

If you opt to use nail guns to install InSoFast panels and/or siding, it is only recommended when temperatures are above 60° F. Smaller nail size and shank diameter will perform better at lower temperatures. It is up to the contractor, and/or building official to determine the suitability for the use of nails when installing siding. It is important for the contractor to verify that the fasteners do not crack the stud and that they are not over-driven or under-driven into the stud.  In cold weather to keep working you can hand nail the siding or for cement board applications switch to ITW Buildex Product Report: Stucco/Cement Board Applications (Rock On Fasteners) (PDF, 127kb)

The Recommended Adhesive:

1. Why Use Loctite PL Premium 3x for exterior masonry projects?

Loctite PL Premium

LOCTITE® PL PREMIUM® POLYURETHANE CONSTRUCTION ADHESIVE

New Look

Green Guard Certified Adhesive:

One of the many reasons we recommend Loctite PL Premium is it has the GREENGUARD Certification.  Loctite PL Premium bonds to most common construction materials such as wood, plywood, OSB, treated wood, concrete, stone *, slate, masonry, brick, foamboard
insulation , metal, stainless steel, galvanized metal, and other cement-based products.

InSoFast panels were designed with simplicity and speed in mind. In unit masonry applications we would argue that gluing them is not only the easiest method of installation but often the most effective. Third-party testing has shown the adhesive bond strength of our studs to have 108psi of holding power. This means each adhered panel is capable of holding over 5,000lbs!

In Canada the Glue is LePage PL Premium

Testing was conducted using Loctite PL Premium’s 3X Stronger Construction Adhesive, (in Canada it is marketed under the LePage PL Premium brand,) on clean concrete surfaces. It is the only adhesive we have tested. Other formulas and brands may not work as expected.

2. Estimating Adhesive Quantity;

Estimating Adhesive Quantity

Estimating adhesive has variables beyond our control, the condition of the wall, and how accurate the tradesmen is with a glue gun? The adhesive manufacturer's technical sheet states, "A 3/8” (9.5 mm) bead extrudes approximately 38 ft. (12 m)."

That is in a perfect world. When PL Premium 3x adhesive is applied a ⅜" bead on the backside of the stud's ribbed surfaces roughly equates to 7 InSoFast panels or 56 square feet of adhered wall. 

The adhesive follows the "Goldie Locks Rule," too much, too little, and just right. Doing just right you can expect that 1 large 28-fl oz tube will cover 21 of our studs (3 studs per panel for 7 panels). 

Other considerations additional adhesive should be included for securing the panels at openings like windows, doors and corners.

1 large 28-fl oz / 828 mL tube = 21 (22" studs) or 7 panels for 56 Square feet of glued InSoFast wall surface.

  • We recommend that you estimate approximately 10% waste or
  • 1 tubes of the adhesive = 50 Square feet of wall.

 To verify that enough adhesive is used, press the panel into place. Pull the panel back and check to see if the adhesive has spread out beyond the full width of the stud. It is normal for the panel to "float out" from the side of the wall when it is accommodating irregularities the adhesive will bridge gaps up to 3/8". Additional adhesive may be necessary in some areas.

4. Important Notice: Container Surface Preparation, Temperature Application;

Important Notice: Surface Temperature Applications

When bonding EPS and XPS foam insulation, use above 40°F (4°C) and avoid cure and surface temperatures above 90°F (32°C). Surfaces must be clean, dry and free of frost, grease, dust and other contaminants. Pre-fit all materials and protect finished surfaces. If using cartridge format, cut nozzle at a 45° angle to desired bead size and puncture inner seal. Be very careful not to allow Loctite® PL® Premium to cure on a finished surface.

Cold/Hot Weather Tips:  

Installation:

Apply adhesive to one surface of the material being bonded. Press the surfaces firmly together within 15 to 20 minutes. Materials may be repositioned within 30 to 45 minutes after applying the adhesive. If bonding two non-porous surfaces (such as foam, metal or rigid fiberglass) or
under very dry conditions (less than 30% relative humidity), add water in the form of a very light or atomized spray from a plant mister bottle to the extruded adhesive.  The repositioning time will then be reduced to less than 15 minutes.

Use mechanical support for 24 hours while the adhesive cures. Cure time is dependent upon temperature, humidity, porosity of substrate and amount of adhesive used. Low temperature and humidity will slow cure time. When bonding the stud or foam insulation, avoid cure and surface
temperatures above 90°F (32°C) as this may cause voids or cavitation of the adhesive. User is responsible for determining suitable and acceptable results for their intended project. Test before use.

Overview / FeaturesTechnical Data / Directions

5. Safety Precautions and Cleanup;

Wear gloves. Cured adhesive on bare skin will not come off immediately with washing and will cause skin to darken. Cured adhesive and discoloration will come off in about 3 days.

Clean tools and uncured adhesive residue immediately with mineral spirits in a well-ventilated area to the outdoors. Remove cured adhesive by carefully scraping with a sharp-edged tool.

Panel Details

 

InSoFast Flat Panel EXe 2.5 is a feature rich continuous insulation panel. The EXe is optimized for exterior wall applications

For legal sake, we should probably clarify that you can try InSoFast panels at home. We don't necessarily condone trying the rock-climbing part at home.

The InSoFast Panel features built-in drainage channels that are specifically designed to direct the flow of moisture out of the wall.


InSoFast Plus Method

Need a higher R-value? No Problem! Start with a base of InSoFast continuous insulation panels they are feature-rich and easy to install. Then add rigid foam insulation over top of InSoFast panels.
