An insulation package contains a plurality of unfaced or faced, uncut and pre-cut fibrous insulation batts of a pre-selected width enveloped within a covering in a compressed condition. Each of the pre-cut fibrous insulation batts has a plurality of longitudinally extending batt sections separably joined to adjacent batt sections by separable connectors. The separable connectors hold the pre-cut fibrous insulation batt together for handling but can be separated along the lengths of the batt sections by hand to separate adjacent batt sections. Preferably, between 20% and 70% of the fibrous insulation batts in each of the insulation packages are pre-cut fibrous insulation batts.

Insulation batt and package

A hinged vent chute, for providing ventilation to an open attic space, includes an elongated chute segment and an insulation dam segment. The elongated chute segment has one or more upwardly open channels, extending from a lower end to an upper end of the chute segment, that provide an air passage from a soffit region of a roof, over an interior surface of the roof, up into an open attic space beneath the roof. The hinged vent chute has a hinge or fold line joining the elongated chute segment to the insulation dam segment which permits the vent chute to be folded downward at the hinge to position the insulation dam segment for securement to form an insulation dam which prevents loose fill insulation in an attic from flowing down into a soffit region of a roof and blocking air flow. The insulation dam segment may also have one or more hinge or fold lines intermediate the ends of the insulation dam segment to permit the insulation dam segment to be folded intermediate its ends when positioning the insulation dam segment for securement to form the insulation dam.

Hinged vent chute

A modularized, encapsulated insulation assembly includes a plurality of insulation modules which each include a compressible, resilient insulation material encapsulated within a vented, flexible envelope which overlays and encloses the major surfaces, lateral surfaces, and at least the end surfaces of the insulation material at the ends of insulation modules facing other modules of the assembly. Where both ends of the insulation material in an insulation module are enclosed within the envelope, the envelope is vented to permit air to pass through the envelope during the compression and recovery of the insulation module. Each adjacent pair of insulation modules is joined by a flexible connector strip which extends between adjacent ends of the insulation modules and lies either substantially in the plane of one of the major surfaces or about midway between the major surfaces of the insulation modules. The insulation modules may differ in length and provide a location between the insulation modules where utilities can pass when the modularized, encapsulated insulation assembly is installed.

Encapsulated insulation assembly

In a method of and an apparatus for forming composite and other fibers, individual filaments from two or more sets of continuous primary filaments of two or more heat-softenable fiberizable materials are brought together lengthwise to form pairs of continuous primary filaments. The groupings of continuous primary filaments are fed into a high energy attenuation blast where the filaments are heated, attenuated and formed into composite or other staple fibers of the heat-softenable fiberizable materials. Preferably, the individual continuous primary filaments of the groupings of continuous primary filaments are fused, adhesively bonded or otherwise joined together, prior to being introduced into the high energy attenuation blast, to prevent the individual primary filaments of the groupings of continuous primary filaments from separating in the high energy attenuation blast.

A system for arresting movement of an aircraft traveling off the end of a runway at high speeds. Rigid, friable, fire resistant foam boards, preferably phenolic foam, are connected to form a panel, and a plurality of layers comprised of stacked panels are adhered to a base surface. The panels are formed from unfaced foam boards, the compressive strength of the stack of boards being less than the force exerted by the landing gear of the aircraft to allow the boards to be crushed by the landing gear.

Aircraft arresting system

A sheathing board capable of transmitting water vapor while retaining good thermal conductivity properties. The board is formed of a core comprising rigid foamed plastic interspersed with spaced areas of water vapor permeable insulating material that extend from one major face of the core to the other. The major faces of the core are preferably faced with a water vapor permeable sheet, allowing water vapor to travel through the spaced areas of insulating material and the facing sheets. By aligning the spaced areas of material with the insulation in a wall cavity, the strength of the board and its thermal conductivity are maintained within acceptable limits.
