Insulation Products For Residential Thermal Applications
What is
R-value
?
Meeting the challenges of today’s
climate zones.
Building codes vary by state/municipal codes
and climate zone
Building codes often differ by state/municipal codes
and climate zone. The insulation solutions shown
on the following pages represent applications based
on specific locations and on current building
code regulations.
While R-value applications will differ depending
on location, thermal preferences and financial
considerations, one factor should remain invariable:
the quality features of your insulation. When compared
to other insulation like foam plastics and fibreglass,
ROXUL
®
stone wool ranks superior for soundproofing
and fireproofing, as well as for ease of installation and
long-term performance in wall systems, floors and attics.
The following solutions are only suggested approaches
to consider. Check with your local building code for
specific details.
ASHRAE – History of R-Value Requirements
The American Society of Heating, Refrigerating and
Air Conditioning Engineers (ASHRAE), is an
international society of technical individuals who
provide knowledge to the building industry on
heating, ventilation, air conditioning, and refrigeration
(HVAC&R). The Society developed ASHRAE 90.1,
an energy conservation standard that provides the
minimum requirements for energy efficient buildings.
This standard, and others are applied today in many
states for commercial, government and high-rise
and residential building applications.
Look to the National Building Code and refer to section
A-5.3.1.2 for information on condensation and energy
conservation standards.
ASHRAE Map of Climate Zones
Every rating agency has its own maps that divide
regions into thermal or climate zones to tailor codes
and standards to what is appropriate for that
particular region.
