1�17 Insulation 1311.1 Instaliation Requirements: All insulation materials shall be instailed accading to the manufaAurers inshuclions to achieve pioper densrties, maintam clearances, and maintain unAorm R-values. To the mapmum extent posside, insulation shall extend over Ihe full component area to the intended R- value. 1311.2 RoollCeiling Insulation: Open-bbwn or poured loose- fill insitlation may be used in attic spaces where Oie slo?e d the ceiling is not more than 3/12 and ihere is at least thirty inches of clear distance from the top of the botlan chad of the truss or ceiling joist to the underside of Pie sheathing at the roof ridge. When eave vents are installei, baffling .�f ihe vent openings shall be provided so as to deflect the incaaing air above the surface of the insulation. Where lighting fiztures are recessed into a suspended or exposed grid ceiling, the mdlceiling assembly shall be msulated m a low6on other than directly on the suspended ceiling Exception: Type IC rated recessed lighting fixtures. Where installed in wood framing, faced batt insulation shall be face stapled. 1711.3 WaIllnsiAation: Extenor wall cavities isolated dving framing shall be fully insulated to the levds of lhe suvounding �valls. When installed in wood framing, faccai baV msulation shall be (ace stapled. Above grade extr.nor insulation shall be protected. 1311.4FIoorinsulaUon: Floorinsulationshallbeinstalledin a permanern manrer in subslantial contact with the sudace being insulated. Insulation supports shall be installed so spacing is not more than iwenty-four inches on center. Installed insulation shatl not block th2 airtlow ihrough foundation venis. 1317.5 Slah•On•Grade Floor: Slatron-grade insulation installed inside the foundaUon wall shatl e�lend dowmvard from the top of the slab a minimum distance of M1venty4our inches or to the lop of the footing, whichever is less. Insulation installed outside the loundation shall extend downward a minimum of twenry-four inches or to the fiostline. whichever is greater. Abwe grade insulation shall be protected. Ezception: For monolithic slabs, the insulation shall extend downward from ihe top of the slab totlie bottom ot the (ooting. 1311.6 Radiant Floors (on or below grade�: Slabon-grade insulation shall entend dowrnvard from the lop of ihe slab a minimum distance of ihirty-six inches or dowrnvard to the top d ihe footing and Mrimntal for an aggregate of not less than ihirry-six inches. If required by the building official where soil condilions warrant such insulation, the entire area of a radiant 9oor shall be thertnally isolated from the soil. Where a soil gas control system �s provided below the radiant fbor, which results in increased convective flow bdow the radiant floor, ihe radiant Iloor shall be thermally isolated from the su�Aoor gravel layer. 1J12 Glaang and Doors 1312.1 Standard Procedum for Determination of Glazing and Door U-Factors: U-lactors for glazing and doors shall be determmed. certdied and labeled in accordance with Standard RS-37 by a certilied independent agency licensed by the Nalimal Fenestration Pating Coundl (NFRC). Compliance shall be based on the Residential or ihe Nonresidential M19odel 5ze Product sanples used for U-'ractor determinatior,s shall be production line units or repr^_sentaMe of urrt� as purchased by the wnsumer a conVactr,r. Unlabeled �aang and doors shall be assigned the default U-factor in S=::in�n 2006. 1312.2 Solar Heat Gain Coefficient and Shading CceHicient Solar Heat Gain Coefficient (SHGC), shall be dMermincd, certified and labeled in accordance vnththe Nation�l Fenestration Ratmg Counal (NFRC) Standard by a certified, independent a7ency, licensed by the NFRC. Ezception: Shading coeffioents (SC) shall be an acceptade aHernate for c«nMlance wiih solar heat gain coelfioent requirements. Shading coeffidems for glazirg shall be taken Irom Chapter 27 of Standard R5�27 or from the manu(adurer's test data. 1 J73 Moisture Control 1313.1 Vapor Retarders: Vapor retarders shall be mstalled on lhe warm side (in winter) of insulaGon as required by this section Exceptlon: Vapor retarder installed with nd mae than 1/3 d the rwminal R-value between it and the conditioned space. 1�13.2 RooflCeiling Assemblies: Roof/ceiling assemblies �•diere ihe ventilalion space above the insulation is less than an average of twelve inches shall 6e provided with a vapor retarder. Roof/ceiling assemblies wAhewt a vented airspace. where neilher the roof deck nor the roof stmcWre are made of wood, shall provide a continuous vapor retarderwith taped seams. Exception: Vapor retarders need not be prwided where all of the insulation is installed between tY.e roof inembrane anC the sirudural roof deck 1317.7 Walls: Wails separating conditioned space from uncondition�d space shail be provided wAh a vapor retarder. 1J13.4 Floors: Floors separating conddioned space from unconditioned space shall be provided with a vapor retarder. 1313.5 Crewl Spaces: A gmund cover of six mil (0.006 inch thick) black polyethylene or approved equal shal be laid over the ground within crawl spaces. The ground cover shall be ovedapped twelve inches minnium at the joints and shall eMend to the loundation wall. Eaception: The ground cover may be omitted in crawl spaces if the crawl space has a concrete slab Iloor wdh a minonum thickness of three and one-half inches. 1314 Air Leakage 1314.1 Building Envelope: The requirements of this sedion shall apply to building elenents separating conddioned from unconditioned spaces. Extenorjoints around windavs and door frames, openings belween walls and foundation. between walls and roof and wall panels; openings at penetrations of ulility services through walls, floors, and roofs: and all other openings in the building envelope shall be sealed, caulked, gasketed, or weatherSnpped to limit air leakage. 1314.2 Glaang and Doors: Doors and operable glazing separaling conditioned from unconditioned space shall be weatherstripped. Pixed windavs shall be tight fiRing with gWss retained by stops with sealarA or caulking all around. Exception: Openings that are required to befire resislant. 1374.3 8uilding Assemblies Used as Ducts or Plenums: Buildirg assemblies used as ducts a plenums shall be sealed, caulked, and gaskeled to limit air leakage.
