Storm panel for protecting windows and doors during high winds
A storm panel of high strength fabric is constructed, reinforced, and installed in such a way as to comply with the building codes as a large missile impact system. When not in use, the fabric can be rolled and stored and placed in an attractive cover without disassembly.
1. A storm panel for effectively protecting windows and doors in wall structures during high winds such as those accompanying hurricanes comprising:
(a) a woven panel of high strength translucent fabric formed primarily from yarns selected from the group consisting of yarns formed primarily of ultra high molecular weight polyethylene fibers, yarns formed primarily of ultra high molecular weight aramids, yarns formed primarily of ultra high molecular weight polypropylene fibers, and yarns formed primarily of blends thereof, said fabric having upper and lower edges and side edges and of such size and shape as to extend across the corresponding window or door;
(b) a fabric hem formed along at least the upper and lower edges of the panel;
(c) a relatively flat reinforcing bar formed of a material selected from the group consisting of metal and plastics and inserted in each hem and extending substantially the length of the hem;
(d) a series of holes at spaced points through each hem and reinforcing bar, a grommet surrounding each of the holes in the fabric layers and reinforcing bar; and
(e) a plurality of anchors for installation through the holes and grommets in each hem and bar and into the adjacent wall structure;
(f) a low density polyethylene film laminated to at least one side of the fabric;
(g) the tenacity of the fibers in the yarns being ≧20 g/d and the denier of the yarns being in the range of 600-1200;
(h) the weight of the fabric being ≦20 oz/yd 2 and the weave of the fabric being selected from the group consisting of plain weave and basket weave; and
(i) wherein the storm panel with its fabric, hem, reinforcing bar, and anchors being effective to pass the hurricane force wind requirements of the 2004 Florida Building Code and the 2003 International Building Code requirements for a large missile impact system.
2. The storm panel according to claim 1 and further including a decorative cover member formed of a fabric material attached along one edge adjacent the top of the fabric panel and having a length such as to substantially surround the panel when in a rolled up storage configuration, and a plurality of c-shaped clips attached at one end to the anchors and substantially surrounding the cover and rolled up panel, the clips maintaining the panel in the rolled condition in the storage configuration, wherein the cover provides an attractive protective cover for the storm panel in a storage configuration.
3. The storm panel according to claim 1 wherein the fabric panel further includes a series of holes with grommets along the side edges and anchors placed through the holes and grommets and into the underlying wall structure adjacent the sides of the window or door.
4. The storm panel according to claim 1 wherein the polyethylene film is bonded to the fabric by a layer of ethylene vinyl acetate.
5. The storm panel according to claim 4 wherein a layer of polyethylene film is bonded to both surfaces of the fabric, each by a layer of ethylene vinyl acetate.
