2 WOOD LIGHT FRAME CONSTRUCTION CLASS DAY 10 - CHAPTER 7INTERIOR FINISHES FORWOOD LIGHT FRAME CONSTRUCTION
3 Interior Construction Sequence After the floor platform (concrete or wood) is completed, and exterior walls, sheathing, roof structure and decking is in place, the building is “in the dry”, meaning if it rains one can still work inside.Interior Partition Framing is done simultaneously with exterior walls if the building is wood frame.If the building has masonry exterior walls, and/or is steel frame, the interior framing does not happen until the building is “in the dry.”Interior Partition FramingSOME MAY BE ALSO STRUCTURAL FRAMINGRough-in (& MPE Equipment)Code Compliance InspectionPRIOR TO COVERING UPThermal InsulationPRIOR TO WALL AND CEILING FINISHES (UNLESS BLOWN IN)Ceiling & Wall MaterialsInterior Millwork, Interior FinishesWALLSFLOORSMPE Fixtures, Devices, Trim, & AppliancesSOFT FLOORING

21 THERMAL INSULATION Purpose is to slow the passage of heat flow Common insulating materials are spun glass fibers and rock mineralInstallation is in interstitial space between outside & insideR-Values are the resistance to the number of BTUs that will travel through a material of given area in a given time period.PurposeRETARDS THE PASSAGE OF HEAT - THERMAL TRANSMISSIONOCCUPANTS MORE COMFORTABLELOWERS UTILITY COSTSMaterialsMOST COMMONBATT OR BLANKET (GLASS WOOL)BETWEEN STUDS (FRICTION, STAPLED)LOOSE FILL (GLASS OR ROCK WOOL)BLOWN INRIGID BOARD - POLYSTYRENEAPPLIED OVER FRAMING,InstallationR-ValuesRESISTANCE TO HEAT FLOWLARGER R - GREATER RESISTANCEMINIMUN REQUIREMENTS PER CODELIMITED BY THE THICKNESS OF STUDS, UNLESS ADD’L APPLIED ON THE OUTSIDE OR INSIDE – A primary reason more and more 2x6 studs are being used.
22 Vapor Barrier installed On warm side of insulationInsulation in Interior WallSpace to prevent soundtransmissionExterior Wall
23 Vapor Barriers on Insulation Insulation can be purchased with or without a vapor barrier.The purpose is to prevent condensation from forming on materials due to moisture in the air and temperature differential.Materials are treated paper, plastic, and aluminum foilInstallation is always on the warm side of the insulation.PurposePREVENT WATER VAPOR FROM ENTERING THE INSULATION AND CONDENSING INTO LIQUIDMaterialsMETAL FOILPLASTICTREATED PAPERON THE INSULATON OR AFTER (FULL SHTS)InstallationVAPOR RETARDER typically PLACED ON THE WARM (INSIDE) SIDE
24 Radiant Barriers are used to reduce the flow of solar heat from infrared and Ultraviolet radiation by reflection.Wall sheathing faced with white plastic or aluminum foil on the outer surface reflect UVs and Infrared.Reflective barriers also include a material called “house wrap”, which not only reflects but provides a barrier to air infiltration due to wind.
25 Wall & Ceiling Finish Ceilings: Drywall, with textured and painted surface, sometimes acoustic spray.Plaster once was the norm, but now is rarely used because of labor cost.Walls:Drywall, with a variety of attached material, such as texture & paint, wallpaper, vinyl fabric, paneling, tile.PlasterNot often usedCEMENTITIOUS TWO - THREE COAT SYSTEMLABOR INTENSIVECOSTLYLARGELY REPLACED BY DRYWALLGypsum DrywallLOWER COSTQUICKER INSTALLATIONLESS SKILLED CRAFTSMAN NEEDEDGYPSUM WRAPPED WITH PAPERVeneer Plaster

37 RESILIENT FLOORINGResilient flooring is material such as vinyl composition tile, vinyl tile, or sheet vinyl.It is a material that must be glued down at the proper temperature, then protected from construction traffic.
38 WOOD FLOORING Pre finished wood flooring is another material that must be protected from constructiontraffic.Unfinished hardwood flooring can beinstalled early, then finished as one ofthe last steps.Types of wood flooring include blindnailed tongue &grooved, squareedge, or woodtiles such as parquet.
39 CARPETCarpet is a final material that should not be installed until last – for obvious reasons.There are two types of carpet, based on the method of installation.Stretch carpet is placed over a resilient pad and held in placewith barbed strips fastened tothe floor.So called, ‘commercial carpet’is a very tight weave material,and is installed with a mastic adhesive troweled on the floor.
40 Many of the processes of finish within a project overlap in the time frame in which they are installed.But every consideration must be given and demanded by the Architect to guard against damage of one material for the sake of another.Finish surfaces should never be done prior to other trades that could cause damage, without adequate protection to the materials.The General Conditions of the Contract for any project will state that damage done to adjacent finish shall be paid for by the trade responsible for the damage.
