Stego Wrap Helps Solve Four Problems in Construction
What's the Problem?
- Government Restrictions - The Canadian Government has implemented restrictions that will discontinue the use of solvent-based flooring adhesives. Floor covering failures and mold/mildew problems increased in the result of government restrictions which caused the removal of solvent-based flooring adhesives and coatings in favor of water-based adhesives and coatings. Similar restrictions went into effect in late 2012.Traditional products no longer suffice to protect these new adhesives and coatings.
- Degradation of Generic Poly - Studies now tell us that standard polyethylene sheeting deteriorates below a slab, sometimes within the first five years. Stego Wrap is constructed with high-grade resin that will not deteriorate. Prime, virgin resins are the key.
Why Stego Wrap?
- Floor Covering Failures - In 1999 in the United States, the EPA set up restrictions on the use of solvent-based adhesives in construction-related activities to address environmental concerns. This created a shift from solvent-based adhesives to water-based adhesives. In 2010, the Canadian manufacturers were forced to make the same adhesive switch. Water-based adhesives are extremely weak when confronted by moisture and alkalinity and have unacceptable rate of re-emulsification. Industry experts now recommend the use of high-performance vapour barriers as opposed to generic polyethylene sheeting to prevent the onslaught of moisture-related problems.
- Mold and Mildew, Indoor Air Quality, Sick Building Syndrome - Mold and mildew is now one of the most costly problems in the construction industry. Unfortunately, mold spores only need three things to grow: A food source (organic material or cellulose-based products), sustained temperature (between 13-50 degrees Celsius), and moisture (relative humidity of 75% or higher). Eliminating the food source is difficult, and room temperature almost always falls into the tolerable range. The only real opportunity to prevent mold growth is to limit the amount of moisture that enters the building envelope.
- Soil Contamination - For a variety of reasons and in a number of different ways, soil gases and soil poisons represent a signification risk to the inhabitants of buildings. Stego Wrap can help protect against the intrusion of radon, methane, chlorinated solvents, petroleum by-products, etc. *To learn more about how Stego Wrap provides superior protection against radon, click here
- Energy Conservation - In the age of "Green" building, Stego Wrap can help to conserve energy which benefits the environment and lowers energy cost to the owner.
What is the Solution?
- Establish Performance Criteria and Reference New Industry Standards in Specifications
- ASTM E 1745 - 09: "Standard Specification for Plastic Water Vapor Retarders Used in Contact With Soil or Granular Fill Under Concrete Slabs" - Class A, B, or C, indicates strength of the membrane and conditioning tests (7.1.1 - 7.1.5) ensure longevity.
- ACI 302.2R-06: Recommends vapour barrier permeance of less than 0.01 perms when utilizing the following floor coverings: sheet rubber, epoxy coatings, vinyl composition tile, sheet vinyl, carpet, athletic flooring, laminates, and hardwood.
- Solution: Specify Vapour Barrier Performance Criteria (Div-3 or Div-7 {CSI MasterFormat})
- Permeance as tested before and after mandatory conditioning (ASTM E 1745 Section 7.1 and sub-paragraphs 7.1.1-7.1.5): less than 0.01 Perms
- ASTM E 1745 Class A
- Not less than 15mils thick
