Insulation devices, methods and related construction techniques are provided. An exemplary device may include a body having a plurality of openings defining an openwork, to allow the passage of air therethrough when placed in contact with insulation material. The device may further include a plurality of spacer struts and/or spacing depressions fixedly attached to the body. The struts may be configured to maintain a predetermined distance between a first side of the insulation material and a building surface. The body and struts act together to define and maintain a space between the first side of the insulation material and the building surface, for example, for ventilation. The building surface can be the bottom face of a roof, an insulated attic floor, wall sheathing or a soundproofed demising wall, for example. The spacer device can be capable of being transported and stored together with, or as a separate item from, the insulation material, and can also be stored in nested layers. The device can also be stored in rolled form. The openwork of the device can additionally or alternatively include a sheet of entangled net filaments or other similar material.

An insulation retention apparatus includes a non-gas-permeable plastic sheet. At least a first foam strip is affixed to the non-gas-permeable plastic sheet along a first side and at least a second foam strip is affixed to the non-gas-permeable plastic sheet along a second side, wherein the first side is substantially opposite the second side. An adhesive is positioned on each of the first and second foam strips, wherein the first foam strip is affixed to a first overhead structural beam with the adhesive and the second foam strip is affixed to a second overhead structural beam with the adhesive, wherein the first overhead structural beam is positioned spaced from the second overhead structural beam wherein the non-gas-permeable plastic sheet is extended therebetween, and wherein a quantity of insulation is retained on the non-gas-permeable plastic sheet.

A seamless sheet installation system preferably includes a seamless sheet and a plurality of sheet retention devices. The seamless sheet is retained on a tube. A pair of rotating retention devices may be inserted into ends of the roll. Each rolling retention device includes a tube plug and a rotating handle. An end of the seamless sheet is secured to the top eave flange. The seamless sheet is held against a bottom of the eave purlin web with one of the plurality of sheet retention devices. The sheet retention device may have any suitable design. The seamless sheet is rolled out to successive purlins, wrapped over the top flange and anchored to a bottom of the vertical web with one of the plurality of sheet retention devices. The seamless sheet wrapping process is terminated at an opposing eave purlin or a ridge purlin. Insulation is then inserted between adjacent purlins.

A holder for supporting a material such as insulation. The holder includes a support member having a first and a second wire element for supporting the material, with each of the first and second wire elements having a first end and a second end adapted to engage two beams. The first and second wire elements also are coupled together by a serpentine section defining a planar holding surface. The second ends include U-shaped clamping members.

A tensioned panel extended insulation system includes a support structure, a panel support structure and a pair of insulation panels. A telescoping tube extended insulation system includes a support structure and a ceiling sheet material. A rafter clip may be attached to a rafter for attachment of an end of the support structure. A cable arched telescoping tube extended insulation system includes an arched support structure, an adjustable spacer, a cable and the ceiling sheet material. A bar joist extended insulation system includes a support structure, an insulation support structure and an ceiling sheet material. A bar joist extended insulation system may be arched. A system for installing ceiling sheet material in buildings preferably includes either two roller supports or two sheave supports, a middle section, a first end section and a second end section. A rotary strut could also be used to replace an existing strut.

A seamless sheet installation system preferably includes a seamless sheet and a plurality of sheet retention devices. The seamless sheet is retained on a tube. A pair of rotating retention devices may be inserted into ends of the roll. Each rolling retention device includes a tube plug and a rotating handle. An end of the seamless sheet is secured to the top eave flange. The seamless sheet is held against a bottom of the eave purlin web with one of the plurality of sheet retention devices. The sheet retention device may have any suitable design. The seamless sheet is rolled out to successive purlins, wrapped over the top flange and anchored to a bottom of the vertical web with one of the plurality of sheet retention devices. The seamless sheet wrapping process is terminated at an opposing eave purlin or a ridge purlin. Insulation is then inserted between adjacent purlins.

This invention provides fall protection systems comprising a suspension fabric, supported by a grid-work of longitudinal and lateral bands, in metal building construction. The fall protection system uses safety clips to attach lateral bands to intermediate purlins, and also provides novel attachments of the lateral bands to eaves and ridges whereby the respective eave and/or the ridge absorbs an enhanced portion of the force of impact when an object falls onto the fall protection system. The invention further provides methods of installing such systems, and buildings embodying such systems.

This invention relates to a system of ventilating a residential or light commercial structure with lightweight, easy to install radiant barriers that reflect external sunlight heat away from the structure, reflect heat produced within the structure to maintain internal warmth, and contain internal air ventilation space to prevent condensation.

An attic baffle radiant barrier for use in unvented attics and vented attics. The attic baffle has a baffle substrate with an elongated H-shape, with a cross-span extending between two legs on the left and right, each leg comprising an upper portion and a lower portion. A tab or extension extends from the respective ends of one or both portions of one or both legs of the H. A radiant barrier layer is affixed or adhered to one side of the baffle substrate. The tabs or extensions may be used for stapling (i.e., using staples) or otherwise fastening the attic baffle radiant barrier to the bottoms, tops, or sides of rafter studs or trusses or similar frame members when installed.
