Roofing’s Weakest Link
Part of the trouble with
research on membrane roofing is the multiple
interactions of roof deck, vapor control, attachment
methods, membrane itself, climate variables, roof
drainage (slope), workmanship techniques, and
maintenance.
Roofing’s Weakest Link
Reflectivity:
not just black or white question
On the surface, it might seem that the question of
how reflective a roof membrane is could simply be a
black and white issue. However, like most complex
subjects, this one encompasses several important
gray areas.
Polyiso Insulation Update
The demand is strong for
polyiso insulation –
find out why,
Introduced more than 30 years ago,
polyisocyanurate gained acceptance by the
construction industry for two critical reasons:
performance in fire tests and R-value.

The Total Building Envelope Concept
Weatherproofing requires a
close examination of all exterior building
components to prevent moisture and air
infiltration....
The building envelope consists of all exterior
components of a building - roof, walls, below-grade
waterproofing, windows, skylights, and so on.
Specifying Healthier, Safer, and More Efficient
Buildings with Air Barriers
T hanks
to increasing interest, air barriers are moving to
the forefront of consideration for the design and
construction of healthier, safer, and more
energy-efficient buildings.
Architects/engineers (A/Es) are well aware that
specifying the proper air-barrier system reduces -
or outright eliminates -
uncontrolled air infiltration and exfiltration.
Bail Out: Campuses
Strive for Leakproof Buildings
The main ingredient for mold — moisture — worms its
way into the walls in one of three ways
Vapor migration, air
infiltration and liquid water literally find cracks
on the outside and stream in. But while the answer
lies in proper installation of windows, walls and
roofs to prevent these paths, experts contend that
addressing this trio starts with old-fashioned
supervision rather than science.

Steep-slope roof
systems require different underlayment installations
When specifying steep-slope roof systems, match
underlayments with a roof's slope and anticipated
service life. In addition, climate, manufacturers'
warranties, fire ratings and building codes should
be addressed
Joan P. Crowe, AIA
describes function, design
considerations and current NRCA recommendations for
the use of underlayments with different steep-slope
roof coverings.
