Stucco Systems - Sto Corp. Sto. Powerwall. It is comprised of the following main components: Sto. Guard. Should water ever reach the back of the cladding, it can drain from the wall assembly via the drainage mat, which also helps speed the drying of moisture- laden air (water vapor) that can accumulate in the wall assembly. Drainage and drying can be particularly important in hot and humid climates and in areas with wind- driven rain. Hairline Cracks In Plaster Board Ceiling Supports For WoodFoam Board Insulation - R Values and Types. By Todd Fratzel on Insulation. Foam Board Insulation Types. I’ve written several posts about how to insulation basement walls in which I promote the use of foam board insulation as the first line of defense against moisture and mold. Because of this I often get questions about which type of foam board insulation to use and what R values these products provide. There are three basic foam insulation board products on the market produced under several different manufacturer names. The basic types of foam board insulation include: polystyrene, polyurethane or polyisocyanurate. They include expanded polystyrene, extruded polystyrene, and polyisocyanurate unfaced or foil faced. Glossary of Commercial Construction Industry Terminology© A B C D E F G H I J K L M N O P Q R S T U V W X Y Z. AAMA – Architectural Aluminum Manufacturer’s. DOW products has lots of information on their site about different foam board products here. I also recommend you read a recent article about Open Cell Vs Closed Cell Foam products to understand the differences between the two product types. Expanded Polystyrene Foam. Expanded polystyrene foam (EPS) is the cheapest and least used foam board product on the market. This product typically has an R value of 3. The key is to put the adhesive on the foam and let it sit for a few mins before you apply to. Hairline Cracks In Plaster Board Ceiling Supports CrosswordExpanded polystyrene insulation is similar to the foam used for packing “peanuts” and it’s typically used for insulated concrete forms also knows as ICF’s. It is also sometimes used on commercial buildings for roof and wall panel insulation which is typically sandwiched between light gauge metal. Cost = Cheapest of the foam insulation boards. Extruded Polystyrene Foam. Extruded polystyrene foam (XPS) also known as blue board or pink board comes in many different thicknesses and edge profiles. This insulation board is probably one of the most widely used foam board insulation products in the residential construction industry. XPS has an R value of 4. In this chapter you'll learn how to patch up walls and floors, two elements of a home that take their bumps and knocks. Fortunately, with some inexpensive materials. A A-frame A wooden or metal rack constructed in the shape of an “A” on which large stone slabs are shipped and stored. Abate To cut away so as to leave parts in. Foundation Crack TIPS. Location, shape and size of crack tells much; Hairline cracks in cast (poured) concrete are normal - See Below! Measure crack width at same. Resene Tech Experts answer your technical questions about Resene products and painting. This is the product that I typically use to insulate basement walls. It’s reasonably priced, light weight and easy to use. This product is also used to insulate the outside of foundation walls and even under slabs. Cost = This product is the middle of the road for these types of foam board insulation products. Polyisocyanurate and Polyurethane. Polyisocyanurate also known as polyiso is seen in all kinds of commercial building applications and more recently with residential building projects. Polyiso is typically used with a foil facing and it has an R value of 7. The reflective foil facing makes it an excellent insulation board when radiant heat is involved. The foil facing also makes it very easy to seal with good quality foil faced tapes. Cost = Polyiso is the most expensive of the foam board insulation products however it’s the highest R value. Polyurethane and polyisocyanurate are both closed- cell foams. They contain low- conductivity gases in the cells (usually one of the HCFC or CFC gases.) The higher R- Values (R 7. This can lead to a couple of disadvantages including: off gassing of HCFC or CFC gases, and reduced R Value over time as the gas escapes.
