This application claims the benefit of U.S. Provisional Application No. 61/669,515, filed Jul. 9, 2012, and U.S. Provisional Application No. 61/816,478, filed Apr. 26, 2013, the contents of which are incorporated herein by reference.
BACKGROUND OF THE INVENTIONThe present invention generally relates to materials and methods of insulation. More particularly, this invention relates to an insulation system for thermally insulating buildings, sheds, houses, and other structures.
Commercial buildings generally are required to meet regulatory thermal code requirements. Although these buildings can be constructed in many different configurations, common configurations include pre-engineered metal buildings having a roof supported by a plurality of metal C or Z purlins generally supported by metal beams and post frame buildings having a roof supported by trusses.
Conventionally, these buildings may be insulated with an insulation material, such as a fiberglass spray foam or a low emissivity reflective film facer laminated on a variety of substrates, such as bubble wrap, polystryrene (EPS), or EPS foam boards. The insulation material is typically laid across the top of the trusses or purlins. Over time, the insulation material may become degraded by age or defect of manufacture, reducing the its thermal insulation capabilities and/or resulting in an eyesore. Replacement or removal of the insulation material can be labor intensive and expensive as the insulation material is often pinned between the roof materials and the trusses or purlins during construction. Generally, the roof deck must be removed to replace the insulation material which may lead to leaks when it is reinstalled.
In view of the above, it can be appreciated that new insulation systems are continuously sought and it would be desirable if new systems and methods of insulating commercial buildings were available that are capable of thermally insulating the buildings without the need to modify the building being insulated during installation of the insulation system.
BRIEF DESCRIPTION OF THE INVENTIONThe present invention provides an insulation system and method of insulation suitable for thermally insulating commercial buildings without the need to modify the building being insulated during installation of the insulation system.
According to a first aspect of the invention, an insulation system for thermally insulating a building includes a plurality of boards, at least two rails secured to supporting members of the building and adapted to secure opposite ends of each of the boards between the supporting members, and a plurality of trim pieces between adjacent pairs of the boards and adapted to connect the adjacent pairs of the boards.
According to a second aspect of the invention, a method of installing an insulation system in a building includes a plurality of boards, at least two rails secured to supporting members of the building and adapted to secure opposite ends of each of the boards between the supporting members, and a plurality of trim pieces between adjacent pairs of the boards and adapted to connect the adjacent pairs of the boards. The method includes securing the rails to the supporting members of the building, securing the boards with the rails between the supporting members of the building so that the boards are suspended by the rails, and securing the adjacent pairs of the boards with the trim pieces to connect the adjacent pairs of the boards.
A technical effect of the invention is the ability to install the insulation system from the inside of a building being insulated without the need to modify the building. In particular, it is believed that, by suspending the boards from support members of the building with the rails and trim pieces, the insulation system can be installed without the need to remove the roof of the building.
Other aspects and advantages of this invention will be better appreciated from the following detailed description.
The present invention relates to materials and methods of insulation generally relating to the insulation of buildings, particularly metal and post frame commercial buildings that are required to meet certain regulatory thermal code requirements. The invention will be described in relation to a commercial building having a roof supported by a plurality of purlins, as is common in the art, although the insulation of other types of buildings with the present invention is foreseeable, such as, but not limited to, houses, garages, sheds, and other types of residential buildings. It should be noted that the drawings are drawn for purposes of clarity when viewed in combination with the following description, and therefore are not necessarily to scale.
The rails 14, each represented as having an F-shaped cross-section, provide the support for the insulation system 10 and are secured to a supporting member of the building. For example,
The trim pieces 16, each represented as having an H-shaped cross-section, are adapted to provide further support to the insulation system 10 by securing the boards 12 to one another.
In combination, the rails 14 and trim pieces 16 provide a support system adapted to suspend the boards 12 in a manner that promotes the thermal insulation of the roof 20 of the building, as represented in
The insulation system 10 is preferably installed to have the UV resistant layer 40 facing downward, that is, towards the interior of the building and/or away from the roof 20, and the reflective thermal resistant layer 36 facing upward, that is, towards the roof 20 of the building. Such a configuration is believed to provide increased thermal insulation to the building as well as a clean, white ceiling and/or roof line. Investigations leading to the present invention determined that the insulation system 10 having the above described arrangement and materials can increase the thermal performance of the building by up to R-10+ or more, and may be installed with a standard R-19 fiberglass batt to create a hybrid insulation system that meets the International Code Council (ICC) R-30 code requirement for metal commercial buildings, as may be required by American Society of Heating and Air-Conditioning Engineers (ASHRAE) 90.1, and further meets the ICC code requirement for ASTM E-84-09 flame spread and smoke developed.
Installation of the insulation system 10 may include securing the rails 14 to supporting members of the building, placing the boards 12 in locations to be suspended or secured by the rails 14 between supporting members of the building, and securing the boards 12 to adjacent boards 12 with the trim pieces 16. Installation can be accomplished with a simple scaffold for many smaller buildings or with the use of a scissors jack or similar device for larger commercial structures.
The insulation system 10 is believed to provide an efficient and economical method of insulating not only newly constructed buildings, but existing metal commercial buildings as well. As previously mentioned in reference to
While the invention has been described in terms of specific embodiments, it is apparent that other forms could be adopted by one skilled in the art. For example, the physical configuration of the rails 14, trim pieces 16, and boards 12 could differ from that shown, and materials and processes other than those noted could be used. Therefore, the scope of the invention is to be limited only by the following claims.
