Securock® ExoAir® 430 Panel

DESCRIPTION Securock® ExoAir® 430 Panel is a glass mat-faced, moisture- and mold-resistant gypsum panel, with a non-combustible core integrated with a factory-applied synthetic vapor semi-permeable air/water barrier membrane. The in-plant application provides a uniform membrane with superior bond resulting in predictable air and water barrier performance and adhesion to the base panel. The panel is a component of the Securock ExoAir 430 Air Barrier System, to be installed using Tremco® sealants and transition membranes to achieve air barrier continuity. The panel is designed for use under a variety of exterior claddings where traditionally a separate gypsum sheathing panel and air barrier would have been used.

ADVANTAGES • In-plant application ensures membrane uniformity and adhesion • Membrane is not climate-dependent and not susceptible to wash out • Panel eliminates sheathing preparation in the field • UV and weather resistance allows the panel to be installed, sealed and left exposed while interior

construction begins

INSTALLATION Securock ExoAir 430 Panel is designed for use under exterior claddings where a conventional gypsum sheathing and air barrier system have traditionally been used. Common claddings include brick veneer, metal, stone or terracotta panels, shingle siding, shake siding and conventional stucco. It’s imperative that the panel is installed with the Tremco approved sealants and transition materials to ensure a 100% monolithic barrier. See Installation Instructions (BE102) for specific details.

LIMITATIONS 1. Securock ExoAir 430 Panel shall not be used as a nail base for exterior cladding. 2. Specific requirements regarding framing spacing, fastener spacing and fastener specifics to

provide required lateral wind-load resistance are the responsibility of the design professional. (Refer to technical data and specifications on the following pages.)

3. Not recommended for lamination to masonry surfaces. Use furring strips or framing. 4. Maximum stud spacing is 24" o.c. 5. Securock ExoAir 430 Panel is not a finished surface. 6. Securock ExoAir 430 Panel is not intended for tile applications. 7. Care should be taken to prevent excess moisture humidity build up on interior side of the panel

(for example: parapets, newly poured concrete or other extensive interior wet work). 8. The Securock ExoAir 430 Panel installed with the approved sealants and transition materials in

accordance with the installation instructions shall not be left exposed for more than six months prior to cladding.

9. The Securock ExoAir 430 System must be installed using only Tremco approved sealants, Dymonic® 100 (in light orange), Spectrem® 1 (in purple).

SECUROCK® EXOAIR® REINFORCING MESH A mesh that is fully embedded in ExoAir® 230 in light orange for transition areas.

EXOAIR® LEF

A single-component, moisture-curing, gun-grade polyurethane foam that is used to insulate and act as a bond breaker around penetrations.

EXOAIR® 230 (LIGHT ORANGE) A fluid-applied, synthetic, vapor-permeable air barrier designed for use in commercial construction applications. It can be sprayed, rolled or trowel-applied to common substrates. ExoAir® 230 can be used as an air barrier membrane on adjacent substrates such as concrete or CMU, and can also be used in conjunction with Securock® ExoAir® Reinforcing Mesh as a transition material.

System Performance

FIELD FLUID-APPLIED MEMBRANES SECUROCK® EXOAIR® 430 SYSTEM

Membrane Uniformity Varies per brand requirements and installation application. Overspray membrane is a field reality resulting in increased cost. Underspray membrane results in underperformance of the air barrier.

Factory-applied for a 20 dry mils Eliminates application variability. Eliminates overspray and possible damage to area. Eliminates waste of product.

Mil Thickness Top air barrier manufacturers’ range from 40 wet mils to 90 wet mils. Requires field test (ASTM D4541) to validate thickness.

Uniform 20 dry mils on every panel.20 dry mils fully tested for air and water leakage and air permeance (ASTM E2357)

Membrane Cure Time Cure dependent on temperature, humidity and surface conditions of substrate. Cure times range from 24-48 hours.

Fully cured on the base panel. Fully cured when it arrives to the jobsite. Accelerates jobsite scheduling and sequencing of work.

Membrane Shelf Life Top air barrier manufacturers’ range from six months to nine months.

Unlimited.

Overall Substrate Preparation Requires the entire substrate to be free of dirt, grease, oil, water, spalled material, sharp protrusions, loose nails or screws. Requires taping of joints and assurance that tape needs no repairs.

Minimal. Remove water, dust and debris under sealant areas only. Speeds installation of the air barrier.

Joint Detailing Requires detailing with adhesives and tapes. Detailing components may or may not have been tested for compatibility. Field testing requires additional time.

Requires detailing with one product. All detailing components already tested for compatibility. Fluid-to-fluid system; no tape used to make connections.

Monolithic Barrier Components’ compatibility must be verified to ensure a monolithic barrier.

Fully tested fluid-to-fluid system ensures monolithic barrier.

Membrane Bond to Substrate Each membrane must be verified for each substrate. The 430 membrane is fully bonded to the core panel. Tested and passed requirements (ASTM C297).

Membrane to Sealant Compatibility Must be verified for each combination under and on top of membrane.

Tested and passed requirements (ASTM D3330). Both Dymonic® 100 and Spectrem® 1 bond sufficiently to the 430 membrane when peeled at a 90 angle.

Washout Concerns Cannot be installed before, during or after rain. None. The membrane is fully cured and fully bonded to the base panel; rain makes no impact to the membrane or installation.

Temperature Impact Top air barrier manufacturers’ application temperature range from minimum 30˚F to 40˚F. Product storage range from 32˚F to 90˚F. Service temperature range from -20˚F to 140˚F.

None.

Need for Specialized Equipment or Jobsite Materials

Airless spray equipment, tenting, possible multiple scaffolding and cleanup products.

None. Equipment to install board is the same as conventional sheathing and uses the same fasteners.One pass installation requires single scaffolding. No tenting required to control overspray to surrounding areas. No specialized materials needed for cleanup.

UV Exposure Top air barrier manufacturer's exposure ranges from six months to 30 months.

Detailed panels have been tested in 12-month cycles in varying conditions showing no change in performance. Detailed panels should not be left exposed for more than six months prior to cladding.

Jobsite Waste Waste includes product packaging and application equipment.

Eliminates 5-gallon pails.

Quality Control Onsite product testing required to ensure compatibility of components used.

In-plant application of the membrane ensures bond and required mil thickness. Detailing sealants are color specific to aid QC. Installers are fully trained and approved to install the system.

Labor Impact Requires two trades (drywall contractor and waterproofing contractor). Requires substantial cleanup with harsh chemicals. Requires finished and exposed surfaces to be protected from overspray.

Bundles sheathing installation with air barrier installation into an efficient delivery method of the air barrier.

Time Impact Requires GC to sequence two trades. Additional time to apply air barrier after sheathing is hung. Substrate preparation can be time consuming.

Installation of the air barrier occurs at the same time as sheathing installation. Building interior can be dried in sooner. Time to prep substrate eliminated.

Cost Impact Variable cost closely tied to application variability.Specialized equipment is costly. Two trades bidding.

More accurate estimating of product. Preapplied membrane means predictable membrane usage and cost; less waste. No surprise costs due to overspray and damage to surrounding areas. Efficient bidding from one trade.

Job Safety Concerns Spray equipment laborious to carry up and down scaffolding.

Reduced concerns with one scaffold and one-pass installation.

Building Complexities Good for multiple penetrations and complex geometries.

No concerns; air barrier already installed with conventional sheathing.
