Concrete Repair Method Statement Pdf' title='Concrete Repair Method Statement Pdf' />This is a general article I wrote, discard what you feel is not relevant to your project. I guess this is the best and most economical way to construct walls that would be placed on the exterior. I prefer to see 2x. You still need that WT BOTTOM PLATE. The best way is to attach WOOD TREATED BOTTOM PLATE to the concrete is to use either. Concrete nails Sometimes this is hard and time consuming Tapcon Screws Relatively easy but again time consuming Hilti Gun with ramset nails Rent the gun, buy nails and charges Very fast and holds great No adhesive is needed. Doing the wall framing 1. Ssc Service Utility 4.20. Concrete Repair Method Statement Pdf' title='Concrete Repair Method Statement Pdf' />O. C. provides a solid base for your 12 drywall. If using traditional framing method, frame your new wall 1 from the vertical blockmasonry surface if using R 1. The reason to keep the wood out from the walls is the moisture that could damage them. If using insulation like R 1. I have stated before that if a homeowner did put thicker insulation in, and the wall was only 1 from the masonry surface, I have recommended hanging a vapor barrier between the back of the wall and masonry surface. This doesnt allow for the insulation to touch the wall and air movement is not restricted but at least you wont create damage to the insulation or wood. Vapor barrier should be placed directly under the drywall. The warm inside air containing water vapor can get past the wall finish and insulation and condense inside the colder wall cavity. If enough of this happens, and the water cannot escape, wood rot, mold, and other moisture related problems are likely to occur. For this reason, building codes often require installing a vapor diffusion retarder on the warmest side of the wall cavity. This is what is required in Minnesota A 4 mill poly vapor barrier must be placed against all concrete or block exterior foundation walls prior to applying furring strips for full height of the wall. Western Wood Products Association, representing Western lumber manufacturers. Another 4 mill poly vapor barrier must be placed over furring strips and insulation prior to covering with finish materials. State Energy Code Requirement MINNESOTA CODE PLEASE NOTE THAT YOU MUST MAKE SMALL SLICES AT GRADE LEVEL ONLY FOR WEEPING IN THE POLY IF POLY IS PLACED AGAINST THE BLOCK ATTACH THE POLY WITH STAPLES TO YOUR JOISTSFOUNDATION SILL PLATE If you do want to increase the R value, move the wall out further or use the R 1. Code advises a 1. Drywall Kraft Faced insulation is fine to use in the above scenario. No need for the poly and you can do everything easily. You may find this easier and I would do this versus unfaced and vapor barrier because I dont like to play with it any more than I have to. Let me add one other thing, rigid insulation used on a concretemasonry surface is fine. Considerations to make in using this is 1. If you are just using 1 12 rigid and furring strips A. You need WT strips to protect the wood. B. The strips can be adhesively applied but they must be solid mechanical anchors may have to be used to insure that if shelving is installed it will hold. Problem with this is, the penetration into a sealed concretemasonry surface is damaged and subject to leaking. C. Any electrical boxes will have to be shallow sometimes makes it hard to wire. D. You must use a fire retardant material over this as per Code. Most books, articles about rigid and furring strips fail to say anything about the use of WT and this will get destroyed and be a good source for moldmildew with the slightest hint of moisture 2. Alternative which does add cost is to apply full rigid sheets to the concretemasonry walls, adhesively applied, then place frame wall against the rigid, then insulate between studs and cover with drywall. The Rigid insulation does then act as a the vapor barrier. Do not tapeseal the seams. This allows it to breath and dry up any condensation that may form. So here is some more stuff. WT is wood treated. International Residential Building Code says it must be used whenever wood is in contact with concrete andor masonry. Check it out with your local inspector. This would also include furring strips applied directly to a vertical block wall unless you use the vapor barrier behind it. If you are considering using 2x. I can only give you my 2 cents worth and you decide A. Are you going to have electrical in the walls Short depth boxes make it difficult to wire. B. Are you planning or foresee hanging shelves or cabinets on the exterior walls Not alot of strength and may be subject to splitting easier than 2x. C. I personally cant seen how 2 will make a difference in conserving space when you consider the hassle of doing electrical or other carpentry issues. D. Depending on what you are talking about when it comes to the pre cut polystyrene, the white foam board, which is the molded expanded polystyrene MEPS only is available in R 2 34 thick, it only costs about 5 per 3. SF. The better quality with R 7. XEPS. This is great stuff but costs more. Just a note, when you use NON WT stock as the 2x. You cant adhesively apply them, you have to use a ramset this obviously has drawbacks. Second, is if you used WT or Non WT stock and have a waterproofing sealer on your block walls, you just penetrated the block, puncturing the seal coating that was suppose to stop watermoisture. Just thought Id bring this up. I would do 2x. 4 walls with R 1. R 1. 3, insulation would cost about. Leave the walls out 1 from the block when framing, apply your poly over the studs apply the drywall and be done. Youll have no problems then. Web Site Blocked.
