THE STEGO ADVANTAGE — SUPERIOR DEFENCE
Against Floor Failures: Experts say “the need for a vapour barrier (as opposed to a vapour retarder) is becoming increasingly clear.” Concrete Construction Magazine, August 2003, p.18. Infiltration of moisture through concrete slabs is a major building defect liability. Stego Wrap Vapour Barrier has an extremely low permeance preventing water vapour, soil gases (i.e. Radon), alkaline salts and soil sulfates from compromising the integrity of the building envelope and leading to serious problems with the concrete slab, floor coverings and indoor air quality. Stego Wrap Vapour Barrier is the best protection against these costly failures.
SPECIFICATIONS
Mould needs three things to survive: moisture, sustained temperature (between 10° and 50° C), and a food source (dust, drywall, etc.). In any given building environment, contractors can only control one of these variables: moisture. Mould spores are present in 100% of building interiors. If moisture is allowed into your building environment, mould can and will grow. Toxic moulds like Stachybotyrus can be fatal for nearly 5% of people (Institute of Medicine 1993), and cause a variety of serious health problems in others. Several recent well-publicised cases involving toxic mould have resulted in multimillion-dollar insurance settlements. Many of the nation's leading Insurance companies have severely limited or removed coverage for mould claims fearing that these claims will bankrupt their companies. Now more than ever, it is critically important that extra attention be paid to preventing the intrusion of moisture vapour from your below-slab environment. Stego Wrap Vapour Barrier offers the level of protection that many architects are now seeking and is considered to be inexpensive insurance against these costly failures.
VAPOUR BARRIER ACCESSORIES INFORMATION AND CODES
Stego Wrap Vapour Barrier is not made with recycled materials and will not degrade. Prime, virgin resins are the key. Molecules within Stego Wrap "interlock" to provide strength, durability and unprecedented resistance to moisture vapour and radon gas. Stego Wrap’s puncture resistance is excellent. Stego Wrap will not tear, crack, flake, snag or puncture, even when 18,000 lb. laser-screed machines are driving directly across the barrier.
