Abstract: Various apparatuses and methods for use in determining the density of insulation in a building cavity are provided. The density of the insulation can then be used for determining the R-value of the insulation. An insulation density measuring apparatus includes a sound wave source and a sound detecting device, such as a microphone, for measuring the sound wave attenuation of a sound wave that moves between the sound wave source and the sound detecting device through the insulation. The sound wave attenuation measurement is correlated with an insulation density.

Abstract: A system for sealing large volumes or gaps includes a flexible envelope that can assume the shape of the volume when filled with a foaming composition that expands the envelope to the boundaries of the volume. The foaming composition may be integral with the envelope or delivered in bulk by an external device. The foaming composition may be one or multiple parts, typically two parts such as a poly isocyanate and a polyols, in which case it is necessary to keep the two parts separate until foaming is desired. Separation may be accomplished by providing multiple compartments that deliver components via a mixing device into the interior. The envelope may include ribs for structural strength and shaping, and leak pores around its perimeter to enhance bonding and sealing. It may also include perforations for bulk, modular seals or for separation of portions of the envelope to seal irregular shapes.

Abstract: An insulation system includes roof sheathing panels, spaced apart structural members, a plurality of pins, insulation support material, and insulation. The plurality of pins are secured to the roof sheathing panels, the structural members, or both. The insulation support material is connected to the pins to form an insulation cavity below the roof sheathing panels and below the structural members. Insulation is disposed on the insulation support material, between the spaced apart structural members and directly under the bottommost surfaces of the structural members.

Abstract: A fibrous insulation member, a mechanism for attaching the insulation member to a building structure, and a method for attaching the insulation member to a structure utilizing the mechanism. The insulation member including a fibrous insulation body having a first lateral surface, a second lateral surface spaced apart from the first lateral surface, and a face extending from the first lateral surface to the second lateral surface. The insulation member also including a facing having a first portion attached to the face and extending the width of the face, and a second portion extending beyond the first lateral surface, the second portion having a first thickness and including a first guide having a second thickness greater than the first thickness.

The foaming composition may be one or multiple parts, typically two parts such as a poly isocyanate and a polyols, in which case it is necessary to keep the two parts separate until foaming is desired. Separation may be accomplished by providing multiple compartments that deliver components via a mixing device into the interior. The envelope may include ribs for structural strength and shaping, and leak pores around its perimeter to enhance bonding and sealing. It may also include perforations for bulk, modular seals or for separation of portions of the envelope to seal irregular shapes.
