Browse the entire list or select a category from this list:. Its uses range from below grade in foundations, to under concrete slabs, to all types of wall construction steel and wood stud, masonry and concrete , and in commercial roofing systems. A: There are several sources.
A: It depends on the application. In sheathing applications screws for steel or wood studs are used with plastic washers or large bugle heads to hold the foam. In masonry cavity walls, the masonry brick ties often have clips or hooks as part of their design that hold the foam board in place in the cavity.
In exterior insulation finish systems EIFS , screws with special plastic washers that cover the head of the steel screw are often used. For roofing systems the amount and placement of fasteners is often dictated by roof system performance listings through Underwriters Laboratories or Factory Mutual.
A: Yes. It also protects foundation waterproofing and dampproofing from damage during backfill. Polystyrene may be damaged by solvent base materials. This caution is not necessary with water based emulsions. Below grade use as a foundation panel requires proper structural design and water protection. Consult with a SIP manufacturer for available options. A: No. To comply with building codes, all foam plastics must be covered with a 15 minute thermal barrier. A: Yes, but to comply with building codes, all foam plastics must be covered with a 15 minute thermal barrier.
A: It is not recommended unless a professional architect or engineer is involved. A: Follow applicable building codes in your area that have been designed to minimize the risk of infestation. See Section Many insect resistance treatment techniques rely on water soluble additives that become ineffective over time and after prolonged exposure to ground water.
Also, termites may travel behind treated boards, between the board and the foundation wall. In that case, the board treatment cannot work, while the board shields the insect path of travel.
Following code requirements for ground treatment, clearance and physical barriers is the best protection. It is an excellent choice due to its high R-value, water resistance, and compressive strength, all suited for below slab use. Q: What products does Owens Corning recommend to be used in a wall construction consisting of a brick veneer and steel frame?
A: The steel stud cavities should be insulated with Owens Corning fiber glass batts, either Thermal Batt insulation or Flame Spread 25 insulation depending on the type of building construction, and the type of facer needed to comply with building code flame spread requirements. Batt facings have different perm ratings that should be considered to suit the particular building conditions. A: It can but is generally not the preferred method of installation.
Therefore it must be field cut to fit. There are other insulation products such as Owens Corning Thermal Batt Insulation that is more efficiently utilized between wood studs. All sheathing materials resist moisture vapor penetration to some degree.
To really assess, it is important to differentiate a couple of key properties, perm rating and R-value. An insulating sheathing keeps the wall stud cavity warmer. Moisture can intrude in at least three different ways: 1 air infiltration, 2 pressurized liquid moisture driven from outside, and 3 vapor permeation and condensation from outside or inside depending on conditions. Well sealed facers on fiber glass batt insulation help limit air infiltration and vapor permeation from the inside.
It is best if the product is covered within 60 days to minimize degradation. Once covered, the deterioration stops, and damage is limited to the thin top surface layers of cells. Cells below are generally unharmed and still useful insulation. A: It is not recommended. All foam plastics have long term creep characteristics that may exceed the deflection limits needed to adequately support brick walls.
Q: What products does Owens Corning recommend for concrete sandwich wall applications? Composite wall design may need an insulation core of different strength. Consult with a structural engineer for recommendations. The ribs provide drainage channels under the pavers. Common protection boards include gypsum and high density wood fiber, usually with joints taped to prevent hot asphalt from seeping down into the polystyrene layers.
A: Class A the best fire resistance rating is based on ASTM E testing of fire spread, and in the case of wood decks, penetration, on the top side of roofs. Ratings are based on complete assembly performance and depend on variables such as deck type, membrane type and the slope of the roof. Commonly extruded polystyrene insulation products have some type of cover placed over them before the roofing membrane is installed.
Cover materials include board products like gypsum or high density wood fiber. Or, depending on the type of membrane, a slip sheet may be used.
PRMA is a generic reference to the same type of roof. Q: What is the major difference between a protected roof membrane assembly PRMA and a conventional roof? A: Conventional roofs place the insulation below the waterproofing membrane keeping the insulation dry but exposing the membrane to temperature extremes and weathering. PRMA roofs place the insulation on top of the waterproofing membrane to protect it from extreme temperatures, ultra-violet light exposure and exposure to foot traffic and other physical abuse.
A: Use readily available adhesives that are marked suitable for use with foam board, or, specifically, suitable for use with polystyrene foam board. Adhesives should be avoided that contain solvent materials as they will dissolve polystyrene insulation boards. A: It depends on the application and the plan of the design professional. Reasons for sealing seams include to create an air infiltration barrier, or, to create a moisture infiltration barrier. A: Silicon or latex based sealants are compatible with polystyrene.
Sealants or caulks that contain solvents should be avoided. A: Generally there are two types of paints, latex and alkyd. Both are compatible with polystyrene. Alkyd paint is also known as oil-based paint. Latex paints contain softer vinyl resins binders and more water. Search Advanced search…. New posts. Search forums. Your purchases. Non-stemming search.

Thread starter berger Start date Sep 21, Scored Squared Edge FoamD at The Home Depot one is marked , and the other is marked , the is a dollar more, but i cant seem to find anything explaining what the difference i other than one being for indoor use and the other for outdoor, but will either of these work for what im using it for?
I use it for making signs and my replica tombstones. The difference between and is the impact resistance rating. The can take 25 psi and the can take 15psi. You can special order even stronger stuff, but I just go with whatever HD has in stock. The color only is because of the manufacturer. This thread is more than 9 years old.
