A construction board includes a foam body having first and second planar surfaces, said foam body including a polyisocyanurate foam matrix defining a plurality of closed cells, said closed cells being at least substantially devoid of hydrocarbon blowing agents, and said foam body being characterized by a density, pursuant to ASTM C303, of at least 2.5 lbs/ft.sup.3; and a facer disposed on a planar surface of said foam body, said facer including a glass substrate having an internal planar surface proximate to said foam body and an external planar surface opposite said foam body, a first coating disposed on said external surface, and a second coating disposed on or proximate to said internal surface, where said first coating disposed on said external surface includes an inert filler, and where said second coating disposed on or proximate to said internal surface includes intumescent material.

Described herein is a roof member or a ceiling member, which is capable of reducing cooling and heating energy consumption by reducing influent and effluent heat amounts between indoor and outdoor environments in such a situation that the indoor temperature is kept constant by use of cooling and heating equipment independently of the outdoor air temperature changes. The disclosed member for roofing or ceiling includes an outdoor-side heat insulating layer (A); an indoor-side heat insulating layer (B); and a heat storage layer between the outdoor-side heat insulating layer (A) and the indoor-side heat insulating layer (B).

The present invention relates to a method of securing multiple layers of roofing material onto a building with need for ballasting objects. A plurality of roofing panels are installed across a roof deck forming a first layer. Then a plurality of fasteners are installed in each roofing panel of the first layer of roofing panels. Each fastener comprises a base having opposing longitudinal surfaces and a fastening member secured to and extending away from each opposing longitudinal surface. An adhesive is then applied to a surface of either the first layer or a second layer of roofing panels. The plurality of fasteners then perforate the surface of each roofing panel of the second layer to secure the second layer to the first layer, thereby allowing the adhesive to cure, preventing wind from resetting the panels, and without external ballasts.

The present invention provides fire-retarded rigid polyurethane foam comprising the reaction product of polyol and isocyanate foam forming components and a dialkyl phosphorus-containing compound, namely a reactive mono-hydroxyl-functional dialkyl phosphinates, as flame retardant, serving as highly efficient reactive flame retardant in said rigid polyurethane foam.

Gypsum panels, methods for their manufacture, and systems and methods for monitoring environmental conditions with such panels are provided herein. The panels include a gypsum core having a first surface and an opposed second surface, a first facer material associated with the first surface of the gypsum core, and an environmental sensor assembly associated with the gypsum panel and configured to detect an environmental condition of the gypsum panel and wirelessly communicate data on the environmental condition to a reader.

The invention relates to a heat insulating element (4) for an interior insulation, a facade insulation, a roof insulation, or the like at a building (1), comprising an insulating body (41) which is of diffusion-open design. The heat insulating element (4) is characterized in that it further comprises a fabric (42), especially a fleece, which is of capillary-active design, and that the fabric (42) is arranged on a surface of the insulating body (41). Furthermore, the invention relates to a building construction, to a method for avoiding moisture damage at a building (1), and to the use of a heat insulating element of this type. This achieves an improved heat insulating element (4) for avoiding moisture damage at a building (1) by means of which it is possible to accelerate drying of the region concerned in the case of the accumulation of water, especially condensation water, with simple means. Furthermore, an appropriate building construction is provided in which moisture damage can be avoided more reliably, and an improved method for avoiding moisture damage at a building (1) is provided.

Devices and associated methods are provided for improving ventilation of insulation material and building construction and renovation. Specifically, the present disclosure includes devices and system(s) to achieve the ventilation of exterior walls and roofs. Components of the system(s) consider shut-down of the ventilation process when it is not necessary, such as in winter, and in the event of fire, where the prevention of vertical and horizontal fire spread is desired.

A rooftop equipment attachment system includes a rooftop having a roof deck, an insulation layer positioned atop the roof deck, a plurality of metallic roof plates that secure the insulation layer to the roof deck, and a roofing membrane secured atop the insulation layer. The roofing membrane covers the plurality of metallic roof plates. The system includes a frame for supporting rooftop equipment. The frame includes a plurality of mounting supports that are positionable atop the rooftop at positions that are above at least a portion of the plurality of metallic roof plates. The plurality of mounting supports are configured to support the frame and any rooftop equipment mounted thereon. Each of the plurality of mounting supports includes a magnetic element that is configured to secure a particular one of the plurality of mounting supports with a particular one of the plurality of metallic roof plates.

The present invention relates to a roof structure comprising support members. Depth locators are provided for fastening to the support members to locate a desired depth of bridge members. The bridge members extend between the support members at the desired depth. A safety barrier is provided for being supported by the bridge members. Each depth locator may include a folded sheet bracket which advantageously resists twisting when fastened to the support members with a threaded depth locator fastener driven by a rattle gun.
