ROOF DESIGN. When the roof p~tch ~s less than 3 in 12, <br /> nembers supporting rafters ann ceiling joist, such as ridge <br /> ~am~ hiE~aQ~ valleys, shall be designed as beans. <br /> <br /> The following is a list of acceptable ridgebea~s: <br /> 1) Solid sawn. DF. Select Structural, 4x14~ or 6x12, or <br /> 2) Glu-lam, DF~ 22F-V4, 3-1/S" x 12". or <br /> 3) LVL nircolams 2.0E~ ES, (2) 1-3/4" x 11-7/8"~ or <br /> 4) Parallam, 2.0E, ES, 3-1/4" x 11-7/8", or <br /> 5) Tinberstrand, 1.5E, 3-1/2~ x 11-7/8% <br />12. RAFTER SIZE. The 2x6 rafters =pacified on the plans are <br /> over spanned. Also~ Energy Path 1 requires R-30 in a vaulted <br /> ceilin9~ therefore, minimun rafter depth, to accept the R-30 <br /> insulation and provide an one-inch air space between the top <br /> of the insulation and botton of roof sheathin~ is 18 inches <br /> . The minimum acceptable rafter size is DF ~2, 2x8 at 16" <br /> on center, but depending on the type of.insulation and <br /> nanufacturer, a 2x1~ or 2x12 nay be neeoed. <br />13. THE VAULTED CEILING area is rQquired.to be. insulated to a <br /> nininum of R-30. Two approvea ~ethoas are. <br /> 1. Provide R-30 insulpti~n~ a conplete v~por barrier, and a <br /> nJni~um of one inch ciear air space anova the insulation <br /> ~or ye~t~la~ion. Eac~ bay ~all be cross ventilated. <br /> 2. uo~pietel¥ zill each oxy wizn a mini~Jm of R-30 (non- <br /> conpre)s~d) insul~tion~ leaving no air space, Provide.. <br /> a co~piese vapor nattier.

SNORE DETECTORS / ALTERATIONS. When alterations, repairs or <br /> additions are nade to an existing dwelling~ the entire <br /> buildin~ shall be provided with snoke detectors located as <br /> require8 for new dwellings. The s~oke detectors are not <br /> required to be interconnected unless other remodeling con- <br /> siderations require renoval of the appropriate wail and <br /> ceiling coverings to facilitate interconnecting wiring. <br /> [Section 316.1.I] <br />15.
