DETAILED DESCRIPTION

[0014] As discussed above, embodiments of the present disclosure relate to an insulator and more particularly to an insulating bulkhead cover as used to improve the heat retention and weatherproofing of a cellar bulkhead.

[0015] An insulating bulkhead cover provides a blanket-like device able to be fastened to bulkhead doors to cover and insulate them, reducing the magnitude of heat loss from an interior of a cellar through the bulkhead. The insulating cover may also be referred to as a bulkhead boot or bulkhead blanket. When installed properly, the cover may be capable of reducing heat transference to the outside to a rate of about 97% efficiency.

[0016] Referring now to the drawings, FIG. 1 shows a cellar door insulating blanket system 100 according to an embodiment of the present invention. Existing cellar door insulating products on the market generally are either of too low of an efficiency, difficult to retrofit to an existing bulkhead door arrangement, or require reconstruction of the bulkhead or bulkhead door framework. In colder climates, energy efficiency is a higher priority than in milder climates. Bulkhead doors, or cellar doors, are one of the largest areas for heat to escape from a dwelling. A particular problem is existing bulkhead doors that already have low energy efficiency. The current invention is a multi-layered blanket that should reduce heat transference to the outside to about 97% efficiency. The bottom layer is constructed of a synthetic weatherproof layer made up of flash-spun high-density polyethylene fibers 40. This bottom layer (or first layer) 40 provides material strength to the bulkhead insulator, provides a vapor barrier, and generally provides waterproofing and a resistance to air drafts. Furthermore, as an airflow barrier, the bottom layer 40 enhances the ability of the insulating layers to work. A second layer 30 is bound to the first layer 40. Second layer 30 may be a compound layer and may include at least one aluminum foil substrate. In a preferred embodiment, second layer 30 comprises a first-aluminum foil layer, a second-aluminum foil layer, and a polyethylene layer sandwiched between the first-aluminum foil layer and the second-aluminum foil layer. Second layer 30 may also include bubble wrap 20, preferably with a large size of bubble. A third layer 10 is bound to second layer 30, such that second layer 30 is sandwiched between first layer 40 and third layer 10. Third layer 10 may include a type of polyester material that is very strong, yet durable and easy to use. This exterior polyester material is to be faced outwardly when the bulkhead insulator is installed, serving as the primary weatherproofing layer, preventing the ingress of water and airflow to the second layer 30, which serves as the primary insulating layer. The assembled insulating blanket would be installed by using a series of fasteners attached to the first layer 40, which may include hook-and-loop fasteners or attachment means (tradename VELCRO) or a magnetic stripping on the inside of the cover for metal bulkhead applications.

[0017] Referring now to FIG. 2 showing a profile diagram illustrating the cellar door insulating blanket 100 (referenced in FIG. 1) according to an embodiment of the present invention. The view in FIG. 2 depicts a cutaway view of the individual layers that make up the cellar door insulating blanket 100. The top layer that may be exposed to the elements is polyester material of third layer 10 that adds strength and durability to the blanket, and provides protection to the inside, less durable materials. Bubble wrap (or bubble pack) 20 may be of an industrial grade that will provide some resiliency to continued use such as handling, rolling, storing, and deploying for over a long period of time. Bubble wrap may be defined as a flexible layer of arrayed, evenly-spaced, air-filled sealed chambers. The third layer 10 may be referred to as a space blanket. The material is a reflective insulation material called an aluminum foil substrate that can reflect a high percentage of low temperature air that manages to penetrate the first two layers. The first layer 40 (the flash-spun high-density polyethylene fibers layer) is the final insulating layer. This layer is more of a synthetic material made up of flash-spun high-density polyethylene fibers that also provides some resistance to continued handling as well as having insulating properties. Cellar door insulating blanket 100 is versatile for use on various types of doors and may be sized for any width or length of door. Layers 10, 20, and 40 may be laminated together, woven together, or bound together by some other mechanism. The exact specifications, materials used, and method of use of the cellar door insulating blanket system may vary upon manufacturing.

[0018] It should also be noted that, under appropriate circumstances, considering such issues as design preference, user preferences, marketing preferences, cost, structural requirements, available materials, technological advances, etc., other methods for insulating a bulkhead, are taught herein.

[0019] The embodiments of the invention described herein are exemplary and numerous modifications, variations and rearrangements can be readily envisioned to achieve substantially equivalent results, all of which are intended to be embraced within the spirit and scope of the invention. Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientist, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application.
