Chapter 9: FinishesLecture 9.1 – Sustainability Considerations, MasterFormat Division 9- General Informationo Most people think of drywall for division 9o Many terms have different names like drywall and sheetrock and gypsum - Spec Booko Those division 5 subsections are similar or related to division 9o Some architects put them in division 9 but for this purpose since the book has them division 5o Anything other than brick or wood paneling in a room would be finishing for the most part Paint Carpet Wallso Difference in divisions in spec book shown in class 5 were load bearing exterior 9 were non load bearing interiors only used to separate things- Sustainabilityo Using recycled materialso Carpet is one item that will give good LEED pointso Waste management when doing remodeling or just throwing waste Does it go to a landfill or does it go to a recycling yardo LEED for New Construction and Major Renovations Location and Transportation Sustainable Sites Water Efficiency Energy and Atmosphere Material and Resources Indoor Environmental Quality Innovation Regional PriorityLecture 9.2 – Cold-Formed Metal Framing- Cold-Formed Metal Framingo Why include metal framing from chapter 5 with finishes from chapter 9? Because it is often included with the Division 9 gypsum board (drywall) subcontractor’s scope of work o Smucker Company – Wall & Ceiling Contractors  Company that can handle cold formed metal framing projects as well as other serviceso Marek – Strength From Within Company whose services includes metal framing and gypsum assemblies This company’s description talks about hospital constructiono Components and Accessories Clark Dietrich Building Systems Company- Deflection Connections- Rigid Connections- Floor Connection- Bridging, Bracing, & Backing- Roof & Truss Connectionso In addition to ASTM, cold-formed metal framing should be in accordance with AISI (American Iron and Steel Institute) standards North American Standard for Cold-Formed Steel Framing – Nonstructural Members Code of Standard Practice for Cold-Formed Steel Structural Framingo Screws are usually used to install, but welding is also common Metal Stud Framing YouTube Video- Dino's Construction prefers using metal studs, because of their light weight and resistance to warping. Easy to cut and fasten, metal studs tolerate moisture far better than woodLecture 9.3 – Gypsum Board and Support Systems- Supports for Plaster & Gypsumo Substrate and supporting construction are vital to a good finish Wood/metal framing and furring- Furring is used for like concrete walls, brick walls so that you can fasten the sheetrock too- Ceiling picture, didn’t want to run the sheet rock the same direction as the joists, so they install the metal furring channels to do so and maybe also to provide more thickness- Calculated deflection- Spacing chart, pg. 676o Substrate and supporting construction are vital to a good finish Concrete, CMU- Control and expansion joints- Moisture problems- Gypsum Boardo Also called drywall or sheetrocko Reference standard: GA-216 Gypsum Association – industry standard for finishing and installing - Gypsum Board Types and Accessorieso Gypsum Board Types Wallboard (interior wall)- Regular core- Foil-backed- Fire-resistant (Type X)o Common in commercial buildings- Water-resistant (WR)o Usually has a green paper coloro Bathroom, kitchen, etc. Backing board- For tiling applications  Sheathing (usually yellow in color) for exterior- Fire resistance- Wind bracing- Base for exterior finishes- Encased in water repellent papero Companies for Drywall Densglass Brand Continental Company- Look at different sheetrock types - Look at different descriptions- Shaft linero Thicker drywall that is heavy but lined in stairwell or elevator shaft National Gypsum- Cavity wall- Shaft wall- Gypsum Board Fasteners & Adhesiveso Wood Studs Type W Course thread screws 5/8 in. minimum penetration to wood studso Metal Studs Type S Fine thread screws 3/8 in. minimum penetration to metal studso Sheetrock Nailso Adhesive  Liquid Nails Brand- Installation – Single Ply (Layer)o Building Codes in College Station ICC – International Code Council International Building Code for Commercial- Even for nails or screws, it is specified what to use and how far apart you need to screw them, etc.- Pretty detailed especially for fire o Substrates Wood and metal framing/ furring Concrete/ masonryo Can be affected by temperature and humidityo Preferably applied perpendicular to joists and studso Ceilings firsto Joints staggeredo Nailing pattern 3/8 in. from edge, 7 in. spacing on ceilings, 8 in. spacing on walls- Special Constructiono Sound Isolation Ashburn Notes- Important in hospitals, apartments, clinics- By law, in like medical places, it needs to be in place- Music studios will have more specialized  Eliminate Flanking Paths Separate Structures Resilient Mounting Sound-Absorbing Materials Increase Weighto Fire-resistant floors, walls, and ceilings Using Type X Sheetrock Increasing gypsum board thickness and/or layers Filling stud cavity with mineral wool Fire ratings are 1-2 hours- Page 684o Moisture-resistant Areas of high humidity like kitchens and bathroomso Shaft walls Used for elevator shafts, stairwells, mechanical enclosures Lecture 9.4 – Acoustical Ceilings/ Treatment and Flooring- Acoustical Ceilingso Ashburn Notes Sometimes called a hanging ceiling, drop ceiling Sometimes have to be designed for the area that you are installing in, like in California, have to have requirements for earthquakeso Acoustical ceiling (integrated) Mostly in commercial Integrated because it has lights and other things in the roof tooo Acoustical baffle More special ceiling Used to bounce sound off like in theaters and stuffo Acoustical wall panels Just mounted on the wallo Installing Video Start with the centerline so it can be symmetrical  Wall angles will support the sides by the wall- Resilient Flooringo Vinyl sheet Kind of like linoleum but for more heavy traffic Easy to clean with minimal joints Like for hospitals Still heavy duty and waterproof Comes in rolls Moisture content is important for all the floors- If too much moisture than you can’t install the floor on the concrete because it won’t stick or it will come upo Vinyl
