Interior Wall Accessories

Roll In Insulation

The building walls are insulated with 3" thick, fiberglass faced on its exposed side with a white metalized polypropylene scrimkraft facing. The faced insulation will have a UL Flame Spread Rating of 25 when tested in accordance with UL723 of ASTM E-84 procedures. The insulation is retained between the interlocking panel ribs with a white PVC hat clip over the panel ribs. Hat clips are made of self extinguishing material per UL Standard 651.

The "U" value through the insulated wall is a maximum of 0.19 BTU's per square foot when calculated in accordance with the "Zone Method" contained in ASHRAE "Handbook of Fundamentals", 1981 edition.

Friction Fit Insulation

The wall system includes 3-1/2" thick R13 unfaced fiberglass insulation. The "U" value of the finished wall system does not exceed 0.16 BTU's per square foot when calculated in accordance with the "Zone Method" contained in ASHRAE "Handbook of Fundamentals", 1981 edition.

Interior finish and vapor barrier for the wall system will be supplied by others.

Lock-In Wall Liner

The interior of the building will be lined with a factory assembled insulated metal liner having no exposed fasteners except at the matching base, ceiling and accessory trim.

Liner panels will be 16" wide and will be nominal 26 gauge embossed galvanized steel, prepainted Arctic White. Insulation willl be non combustible, nominal 1" thick, 2# density fiberglass laminated to the liner panel. The "U" value of the finished wall system will not exceed 0.19 BTU/sf when measured in accordance with ASTMC-236.

Lock-In Wall Liner Plus

The interior of the building willl be lined with a factory assembled insulated metal liner having no exposed fasteners except at the matching base, ceiling and accessory trim.

The wall liner system will have a concealed insulating board of 1 1/2" thick polyisocyanurate foam impaled on rib clips.

Liner panels will be 16" wide and will be nominal 26 gauge embossed galvanized steel, prepainted Arctic White. Insulation will be non combustible, nominal 1" thick, 2# density fiberglass laminated to the liner panel.

The void between the exterior wall panel and the lock-in liner will be insulated with 3-1/2" thick R13 unfaced fiberglass insulation with a calculated U of .05 for the total system.

Formed Wall Liner

The interior of the metal walls will be lined with 32" wide, nominal 26 gauge galvanized steel panels, prepainted Arctic White with 1/4" high by 1" wide flutes on 8" centers. The exterior panel void will have 3-1/2" thick R13 unfaced fiberglass insulation.

The liner system will be furnished complete with White base molding and White trim.

The "U" value of the finished wall system will be 0.16 BTU's per square foot when calculated in accordance with the "Zone Method" contained in ASHRAE "Handbook of Fundamentals", 1981 edition.

Perforated Formed Wall Liner-A29

The A29 Acoustical Wall System consists of a nominal 24 gauge galvanized steel panel, prepainted Arctic White with 1/4" high by 1" wide flutes on 8" centers. The liner panel will have 1/8" diameter perforations spaced on 3/8" staggered centers. The exterior panel void will have 3-1/2" thick R13 unfaced fiberglass insulation. There will be an eight inch thick, one inch wide, closed cell foam tape installed between the interior perforated liner and the exterior wall panel flange. The system will have a NRC rating of 0.90 and STC rating of 29 when tested in accordance with ASTM E90 and E413.

A49 Acoustical Wall Liner

The A49 Acoustical Wall System consists of a nominal 24 gauge fluted exterior panel with a minimum 3" thick, 16" wide, 4# density fibrous acoustical insulation in panel void. A 1/2" thick sound buffer board will separate the exterior wall system and a flush 26 gauge metal septum
panel. The septum panels will be installed perpendicular to the exterior wall panels with voids filled with 3" thick, 16" wide, 4# density fibrous acoustical insulation. A vibration retardant tape will be installed between the septum panel ribs and a perforated formed liner panel. The system will have NRC of 1.00 and STC of 49 when tested in accordance with ASTM E90 and E413.

Gypsum Board

The wall system will include 3 1/2" thick, R13 unfaced fiberglass batt insulation, vapor barrier (optional), furring strips and 1/2" thick gypsum board.

Partitions

Partitions will be constructed of 3" x 16" interlocking flush type smooth or embossed surfaced panels in a nominal 24 gauge galvanized steel, factory painted Arctic White. Partitions will be furnished complete with base channel, wall cap and all required fasteners.
