PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The Magney housing unit is a 2-bedroom 1-bathroom house roughly 1200sqft. The house was acquired by the NPS in 1977 and is currently utilized as a housing unit. The home is a poured concrete and block structure with LP smart siding and standing seam steel roofing. The building is in good general condition but requires some updates. Currently the house utilizes two window mount AC units for air conditioning. These units require installation and removal every year, are 10 plus years old, and allow rodent and insect intrusion. The current attic fiberglass batten insulation is inadequate and smashed down from access traffic, this results in loss of building efficiency. The electrical panel is believed to be original at least 49 years old and needs to be replaced to meet building codes and remove safety concerns. There is currently no bathroom fan/ventilation. This results in mold and mildew issues and complaints by tenants.

PRODUCT DESCRIPTION

Basic Use: CertaSpray® Closed Cell Foam is a two-component closed cell spray foam with a zero-ozone-depleting blowing agent.

When CertaSpray A-side is mixed with CertaSpray B-side closed cell under pressure in a 1:1 volumetric ratio, they react and expand into a medium-density closed cell foam with an in-place core density of nominal 2.0 pcf.

Benefits: CertaSpray Closed Cell Foam provides thermal insulation for the interior or exterior of the building while also reducing air and water vapor infiltration through the building envelope.

Applications: The closed cell 2-pcf foam can be spray-applied into open wall cavities, perimeter joists, cathedral ceilings, garage ceilings, attics, exterior walls and crawlspaces. When covered by a 15-minute prescriptive thermal barrier, thickness is not limited. Product must be finished according to local code, and must be applied by a qualified applicator.

Composition and Materials: CertaSpray Closed Cell Foam is a medium-density, MDI-based polyurethane thermoset foam.

LIMITATIONS

Foam Plastic Insulation: CertaSpray Closed Cell Foam is defined by the building codes as a foam plastic insulation.

Thermal Barrier: Many building codes require that foam plastic insulation be covered with an approved 15-minute thermal barrier. Consult local building code officials to ensure the application meets local building codes and regulations.

Vapor Retarder: CertaSpray Closed Cell Foam meets the performance requirement for a Class II vapor retarder at 1" thickness. Check local building code for climate-specific vapor retarder requirements.

Lighting Fixtures: The National Electrical Code prohibits installation of any insulation over or within 3" (76 mm) of recessed light fixtures unless approved insulated ceiling (IC) light fixtures are used.

Maximum Use Temperature: CertaSpray foam should not be in contact with equipment or materials that have operating temperatures greater than 180°F.

All application surfaces must be free of oil, grease, dust and debris. Surface must be dried prior to application of spray foam. Do not apply this product when the dew point is within 5°F of the air temperature, or when the substrate moisture content is greater than 18%. Excess humidity may cause poor adhesion and result in product failure.

To avoid overspray, product should not be applied when conditions are windy.

CAUTION: CertainTeed recommends that you consult an HVAC expert and comply with guidelines established by applicable building codes prior to using any closed or open cell spray foam insulation product in an attic retrofit application. If not installed correctly, adding spray foam to a vented attic may significantly impair the performance of the HVAC system and may cause other damage to the building. CertainTeed will not assume any liability or responsibility for any personal injury or property damage occurring as a result of the improper installation of spray foam insulation that is not in accordance with the instructions accompanying the product, that is not in conformance with any applicable building codes or that is contrary to the advice given by a duly qualified HVAC expert.
