Image
Install birdstop at the eave in tile roofs to minimize the accumulation of debris, a fire hazard, at the roof edge.
Image
Moisture-resistant plastic and fiber cement exterior trim and cladding are indistinguishable from wood building elements.
Image
Right – The insulation has been located to the exterior of the thermal mass in this wall section
Image
Right – This fire-rated wall assembly uses exterior gypsum board and an exterior siding of fiber-cement or metal to increase fire resistance.
Image
Right – Two-thirds of acrylic tape is offset above the joint and over and above the fasteners
Image

Shear Strength Comparison Between a Foundation Stud Anchor (on left) and a Shear Transfer Angle (on right)
Image
The cool shingles on the right have been coated with a ceramic coating to reflect near-infrared radiation, resulting in a cooler roof as shown by these thermal images (red and yellow are hotter, green and blue are cooler).
Image
The white TPO membrane roof on the row house on the right performs extremely well at reflecting solar energy and maintaining cool surface temperatures while the black EPDM membrane roof on the left heats up rapidly in the sunlight
Image
Thermal mass causes a time lag in the transfer of heat as well as a dampening of peak temperatures, as shown by this plot
Image
These wildfire-resistant decks have a solid decking surface, metal railings, and the underside timber supports are covered with flame-resistant fiber cement board; also the decking is set back from the vegetated slope.
