Insulation batt with integral air vent

Abstract

An insulation product having an integral air vent channel is disclosed for use in attic and cathedral ceiling applications. The product includes an insulation blanket having at least a pair of raised strips formed on one side thereof. When installed, the blanket is fit up between a pair of roof rafters until the raised strips contact the undersurface of the roof. The strips ensure that a predetermined offset exists between the insulation blanket and the roof, thus forming an unobstructed ventilation path running from the soffit to the roof peak. The raised strips can be foamed polyurethane or other polymer material that is dispensed or laminated onto the insulation blanket after the blanket exits the curing oven. The blanket may be a foamed polymer insulation that is extruded as a blanket at the proper insulation height for installation or may be cut to size from an overthick bun of insulation. The blanket and strips may be formed by a mold that shapes a pour in place foam. The blanket, with attached strips, can then be compressed for packaging and shipping. When unpackaged at the work site, the insulation product can be installed between roof rafters without the need for a separate vent panel, thus simplifying the installation process.

AI Technical Summary

Benefits of technology

[0013]An insulating structure is disclosed for maintaining a ventilation space between insulation material and a roof structure. The insulating structure may comprise an insulating body portion having first and second major surfaces and a longitudinal axis; and a plurality of support members disposed on the first major surface. The support members may each have a length oriented substantially parallel to the longitudinal axis of the insulating body portion and a height which extends said support members outwardly from said first major surface. The plurality of support members further may be positioned in late

Problems solved by technology

Unfortunately, thicker attic insulation can lead to poor air circulation when the spaces between the roof joists and the top wall plate of the building are closed or obstructed.

As a result, there is a chance that the installer may inadvertently fail to install the vent or may install fewer vents than is desirable for optimal venting of the roof structure.
