Thermal & Moisture Protection

A. Floor, Wall and Ceiling Insulation

  2. Fill all spaces between doors or window frames and structural members with strips of insulation, pack full.

  3. In crawl space, staple between joists: Vapor barrier toward the ground.

  4. Ceilings: Staple insulation between the ceiling joist, vapor barrier toward the room side.

  5. All insulation: applied in strict accordance with manufacturer’s directions.

  6. The use of advanced infiltration reduction practices (better air sealing practices) is encouraged.

2. Insulation

  1. It is required that the following R-Values, or any combination thereof, be utilized for whichever purpose it is intended.

  2. R-30 - Attics or uppermost ceiling in dwelling. Only accessible areas of attics are to be insulated unless otherwise specified in the Scope of Work.

  3. R-19 - Walls or floors over unheated crawl spaces.

  4. Rigid board insulation (polystyrene, urethane, glass fiber etc.) can only be used below grade and must be covered with a minimum of 1/2” gypsum board or other finishing material for fire safety.

  5. USE OF UREA - FORMALDEHYDE FOAM IS PROHIBITED

  6. All insulation material must meet either federal or American Society of Testing Materials (ASTM) specifications.

  7. Batts or blanket insulation is to be installed with the barrier to the lived in side of space to be insulated.

  8. If two layers of insulation are needed, or if new materials are being added to insulation already in place, the second layer should be of the type that does not have a vapor barrier. If this type is not available, either remove or slit vapor barriers in various places. This is essential to prevent moisture build-up which reduces insulation value and could cause structural damage. Insulation is not to be packed around “hot spots” such as recessed light fixtures, electric motor, etc. Batts or blanket insulation shall be kept 3” away from such “hot spots”. In the event loose insulation is being used, a baffle shall be installed. In either case the top of fixture, etc., is to remain exposed. To avoid obstruction of ventilation care should be exercised that insulation, whether blanket or blown in fill, does not shift into vents or eaves. Batts or blanket insulation for wall installation shall be of the type that vapor barrier flange can either be stapled or nailed at a maximum of 12” intervals.
