Thermoplastic storm windows

 Thermoplastic storm windows larger than 16 square feet shall have permanent retaining clips or other suitable fasteners compatible with the window materials installed to prevent inadvertent removal and/or lateral movement of the storm panel in any direction, parallel or perpendicular to the glazing surface, under normal conditions. The clips or fasteners shall be disengagable to enable window cleaning, maintenance, and exit through operable prime windows.   Stacking multi-poled, polymer-based magnets is not permitted.
Floor Insulation and Ventilation
Applicability. This improvement is applicable only if none of the following conditions exist: • Presence of any effective floor insulation • Underfloor area of insufficient height for installing floor insulation • Floor is over an area that is being converted or will be converted to a conditioned space • Underfloor area is subject to moisture problems (such as flooding or drainage problems)
Material Specifications. Materials installed as floor insulation must be an acceptable material suitable for floor insulation.
When physically possible, a continuous ground cover vapor barrier should be applied to cover approximately 80 percent of the crawl space ground surface to assist in keeping crawl space humidity at a low level. This will decrease the ventilation requirements as shown below. If a ground cover vapor barrier is not feasible, additional crawl space ventilation may be needed as described in these Standards.
Six mil polyethylene or 55 lb. roll roofing shall be used.
Ventilation. The frame and screening materials used for the foundation wall vents shall be constructed of durable materials (preferably metal) and be of sufficient size and number to provide the minimum required net free area of ventilation as shown below.
