Embodiments of the invention provide roofing boards and roofing systems having improved fire resistance properties and methods related to the same. According to one aspect, a roofing system is provided. The roofing system includes roofing panels positioned atop structural support members to form a roof deck. Roofing boards are positioned atop the roof deck and coupled thereto and a roofing membrane is positioned atop the roofing boards and coupled therewith. The roofing boards include a coating of a mineral based material applied to one or more surfaces in an amount between the range of about 0.10 lbs/ft.sup.2 and about 0.70 lbs/ft.sup.2. The mineral based material coating enables the roofing boards to pass the UL 790 class A tests, such as the burning brand test.

A structure with integrated insulation. The structure with integrated insulation includes a steel frame. The steel frame includes a first support beam and a second support beam. The structure with integrated insulation also includes an assembly with integrated insulation. The assembly with integrated insulation includes a first building panel with integrated insulation, the first building panel with integrated insulation being attached to the first support beam on the first surface of the first building panel with integrated insulation. The assembly with integrated insulation also includes a second building panel with integrated insulation. The second building panel with integrated insulation 4 includes an indentation in the first surface configured to receive at least a portion of the first building panel with integrated insulation. The second building panel with integrated insulation being attached to the second support beam on the second surface of the second building panel with integrated insulation.

A protected membrane roof system for installation on a roof decking comprising an upper insulation board having an upwardly-facing upper board top surface and an opposite downwardly-facing upper board bottom surface and at least one through-hole communicating therebetween, a ballast material positioned over the upper insulation board, a netting positioned over the ballast material, and at least one fastener assembly having a base seated substantially adjacent the upper board bottom surface, a rod extending substantially vertically from the base of sufficient size so as to extend through the through-hole of the upper insulation board, the ballast material, and the netting, and a cap engaged with the rod above the netting, whereby the wind uplift resistance of the protected membrane roof system is improved and scour of the ballast material is reduced by effectively anchoring the netting to the upper insulation board beneath the ballast material.

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.
