COMPRESSIBLE THERMAL INSULATION BATTS SEALED IN WATERPROOF BAGS FOR BUILDING CONSTRUCTION
Technical Field
This invention relates to the packaging of thermal insulation batts in airtight bags in a compressed condi¬ tion for storage and transportation purposes, and the installation of the batts into buildings in a sealed decompressed condition. Background Art
Air has always been considered to be the best in¬ sulator against the transfer of heat from one solid to another. However, where insulation is very -exactly considered, certain inert gases, such as Argon, have been found to be more insulative than air. Before the 1930's, 4" of airspace in a stud wall were considered ample insulation. Tests proved that because of circulation within .the 4" cavity, a 5/8" cavity actually was just as insulative as a 4" cavity. Then materials were inserted into the 4" cavity to baffle, or prevent, air circulation. This brought the insulation value up to what 4" of air should be, less, of course, any heat transfer by the baffling materials themselves. For instance, damp sawdust used in early times to keep ice from melting in an "ice house" proved to be a poor insulation, especially when used in the walls of homes. In time, rockwool, glasswool or fiberglass wool became recognized as the lowest cost air circulation inhibitors, or insulation.
Fiberglass has become the most widely used insulation material. Besides being very competitive in price, it can be compressed to a fraction of its normal bulk for storage and for transportation purposes, with full recovery for installation. This lowers storage and transportation costs.
However, fiberglass, which is hydroscopic and sponge- like, will absorb water, and even water vapor, from inside a heated building. Water absorption causes the fiberglass to lose insulation value, and also causes it to settle and create voids where there is no insulation. Great care is taken during construction to keep fiberglass dry, and the whole living area is literally sealed to prevent water vapor from the living area reaching the insulation. Also, in the event of water leaks, the insulation is ruined. Disclosure of the Invention My invention teaches how to protect hydroscopic insulation from absorbing moisture by sealing it in a vapor proof container or bag. Though many types of plastic materials can be used for the airtight sacks. Mylar appears to be the best, as is illustrated by the Mylar balloon, which holds its air, or gas, so well. The insulation sack could also be silvered like the toy balloon, which will give it the extra benefit of all around reflective insulation.
The insulation-filled balloons, or sacks, would take a lot of storage space and would be bulky for transporta¬ tion. To solve this problem, I propose that the insula¬ tion material be compressible fiberglass, and that the sealed bag have built into its side, a "ziplock"-like closing method about 4" long. Then, the bag and its insulation can be fully compressed and "ziplocked" sealed. The compression force can be removed, but the bag will remain in its crushed condition because the fiber-glass can't rise against the air pressure until the "ziplock" seal is opened to let air back into the sack. A number of compressed batts could be tightly packaged together so that possible slow leaks will not allow the batts to decompress, and the batts could be held tight against expansion when transported over high altitudes. By storing and transporting the bags in a compressed con- dition, costs are reduced.
Standard fiberglass dimensions should be used, 141/2" or 22 1/2" wide, for a tight fit between studs, or joists at 16" o/c.and 24" o/c respectively. Standard thickness of 2 1/2", 3 1/2", 5 1/2", 9" and 12" should be used, and lengths can be 22 1/2", A ' and 8'. The plastic sacks should be exactly made to the above dimensions as re¬ quired, so that the batts will look like rectangular boxes when fully extended for installation. Also, the fiber- glass can be sealed into long tubes of say, 22 1/2" x 5 1/2" x 24', sealed at one end, and then from that end, tightly rolled until all possible air is squeezed out, and then sealed at the other end. Then rolls bagged for storage and transportation, as taught by Blackmore Patent 4,555,107, and by Hoffmann, Jr. Patent 3,747,743. During installation, the tubes will have to be cut. They can be closed simply by sealing on a plastic cap with "Scotch Tape".
The plastic sacks should be built with tapes on each side to aid stapling in place, as are standard insulation batts.
Sticky tape like "Scotch Tape" can be used instead of a "ziplock" type of air slit closer.
Using fiberglass batts enclosed in airtight sacks would have many advantages during construction. They can be tacked in from above to floor joists before the subfloor is installed, and in damp weather. For tight crawl spaces that have to be insulated on the back from below, after the house is roofed in, this can mean greater efficiency and less cost. The batts can be more easily forced into tight spots while still compressed. Once in place, they can be inflated to tightly fit the spot. By using small, uninflated 14 1/2" x 22 1/2" batts around pipes and in difficult places and then inflated, it is possible to not have to cut any batts, so that handling fiberglass, and perhaps breathing it in, can be avoided, saving the workmen discomforts. The batts can be in¬ stalled from above, between rafters, before roof boards are installed, which is easier than doing it from below after the roof is finished. The batts can be installed between cavity brick walls and cavity log walls, as the walls go up in damp weather.
In fact, fiberglass in waterproof bags could be used in most situations now, only possibly using rigid foam board or cork insulations, which are more costly.
Many types of insulation batts are paper or foil covered, using highly volatile adhesives to attach them to the insulation. Such adhesives are considered to be a fire hazard. No adhesive is necessary to attach the fiberglass batts to the plastic sacks, as the batts and the sacks have the same dimensions and the batts are completely contained by the sacks.
There are inert gases, such as Argon, which are commonly used in thermal windows because they are more insulative than air. "Argon gas can be compressed into a tank with a hose dispensing means like scuba gear, and the gas can be injected into the bags on the construction site, and sealed. The bags would be more insulative, and the gas would not support fire. Alternatively, enough Argon gas to fill a bag could be compressed into a bottle, which could be inserted into a crushed bag at the plant and permanently sealed within the bag. Then, when the bag of compressed insulation is ready to be installed on the construction site, the bottle neck could be cracked with pincers or pliers, being careful not to cut the Mylar or plastic bag, and the gas and the compressed fiberglass insulation would fill out the sealed bag ready for permanent installation. Or, the bags could be inflated at the construction site using compressed Argon gas in a container which can be released within the bag by means of a pull tab trigger method, as is used to inflate airplane life vests. Instead of crushing the bagged insulation and sealing it in its compressed condition, for ease of storage and transportation, the air can be evacuated from the bag using shrink wrap equipment, which also heat seals the crushed bag. The compressing equipment should be used at the same time to be sure the bag is compressed to a desired dimension. If the shrink wrap compression equipment is used directly on the bag of insulation, the bag will take on grotesque shapes. This process of compressing the insulation and sealing the bag would be more costly to set up capital wise, but should be cost effective for mass production. Brief Description of the Drawings
