DOUBLE-WATERPROOFED INSULATING SHEATHINGgreater insulation greater structural strength faster applicationTurnbuckle Test proves superior wall bracing strength ofCelotex Insulating Sheathing over horizontal wood sheathing.CELOTEX ASPHALT-IMPREGNATEDBACKER BOARDwith Shingles over Celotex InsulatingSheathing (or other Fiberboard Sheathing)It's double-waterproofed by (1) an integral treat ment of individual fibers and (2) an asphalt coat ing of surfaces and edges. This means extra mois ture protection at job site, plus elimination of needfor building paper except where local conditionsmight require. Though double-waterproofed, thisSheathing has more than twice the vapor-permeability advocated for wall sheathing by government agencies.It offers the economical answer to modern re quirements in wall construction, furnishing the de sired increases in insulation value plus strongsheathing in one material at one cost. When Celo tex 25/32 Insulating Sheathing is used in place ofnominal 1” wood sheathing in standard framewall construction (wood siding, sheathing, airsPcJf ' gyPsum lath and plaster), it increases thewall s insulation value 24%; FHA home insulationrequirements for practically the entire country aremet. For minimum-cost construction, Celotex V2"Insulating Sheathing produces a wall that'sstronger, yet has 29% more insulation value thana standard frame wall sheathed with V2" qvpsumsheathing.The large, lightweight units go up speedily.Average time, substantiated by many builders,is 8 to 10 hours per 1000 sguare feet of wall areaagainst15 hours for horizontal wood sheathing. Nodimensional loss—Celotex sizes are actual.NO CORNER BRACING REQUIRED25/32" Celotex Insulating Sheathing, 4' wide, applied verticallywithout corner bracing, greatly exceeds racking strength re quirements established in FHA Technical Circular No. 12 (rack ing strength at least equal to horizontally-applied wood sheath ing with let-in bracing is minimum requirement). Structuralbracing strength of all types of Celotex Insulating Sheathingexceeds that of conventional sheathing. Comer bracing may beomitted with W 4' wide Big Board or 25/32" Celotex InsulatingSheathing unless required by local regulations.with Wood Shingleswith Asbestos-CementSiding Shingles(1) Celotex Sheathing(2) Celotex Backer Board(3) Wood Shingles (Shakes)(1) Celotex Sheathing(2) Celotex Backer Board(3) Asbestos Shingles(4) Wood Stripping (ShingleNailing Base)Recommended-Type Nail with Wood Shingles: 2" annular-grooved.Celotex Backer Board provides uniformly smooth undercoursing;adds insulation value for more comfortable interior in all seasons;builds strong shingled walls with deep shadow lines. 5/16" thickunits, 13W x 48" and 15Vfe" x 48" for wood shingles, and 11 s/4" x48" for asbestos-cement siding shingles.IMPROVED V-TYPEJOINT ON CENTERMATCHEDNote wide, strong shoulders protect ing groove; also tapered, square-endtongue.

Set tongueand-groove joints securely together and stagger end joints insuccessive courses.4.Bring Sheathing units to close contact with frame aroundwindows and doors where a snug joint is desirable.5. Ends of wood siding should fall over center lines of studs.When ends fall between studs, use special clip fasteners onback side at joints.6 Allow W minimum air space between masonry veneerand Sheathing.7.Under masonry veneer, apply non-corrosive metal ties atrate of one tie to every 160-260 square inches of wall area,nailing through Sheathing into studs with 1" nail penetration.No building paper, unless required under local regulations.8 Sheet metal or prepared roofing flashing should be pro vided over casings of all windows and doors.25/32", 4' wide InsulatingSheathing may be used on studs spaced 24" o.c. with comerbracing where this construction complies with Regional FHAminimum property requirements for one-story homes as wellas local building regulations.Wider Nail Spacing—Forwood siding and stucco lathsecured to framing with nails driven through Sheathing andinto studs, spacing of nails may be increased as shown inPanels (B) and (D) except where local building regulationsrequire additional nailing.Sheathing Paper—Vapor-permeable sheathing paper isnot necessary over Celotex Insulating Sheathing unless re quired by local building regulations. Under FHA MinimumProperty Requirements, sheathing paper is required only be hind stucco exterior finishes.Application of Exterior Surfacing—Wood shinglesare applied over horizontal wood stripping, spaced to fit shingleexposure.
