Threre
are many different types of insulation materials to
choose among when applying a commercial roof or retrofitting
an existing structure. The function of roof insulation
is to insulate the building against heat flow in and
out, while providing a smooth, dry, clean and firmly-attached
substrate for the roof membrane.

Proper insulation
is necessary for energy efficiency, condensation control and, in
some systems, structrual integrity against uplift pressure.
Extruded polystyrene
foam (XPS) insulation has a combination of properties that make
it a strong and efficient insulating material. Its proven resistance
to moisture; reliable strength and durability--even without a facer
or coverboard; and stable long-term R-Value make it a top insulating
material for commercial, industrial and residential structrures.
Benefits of
using XPS in roof applications also have positive environmental
attributes, such as long-term durability and recyclability—making
XPS an ideal choice when re-roofing a building.
| And, in Direct-to-Steel Deck
applications; cost savings are achieved because you no longer
require a thermal barrier between the insulation and the metal
deck. |
|
| |
Making a choice for XPS as
your conventional roofing system insulation allows for excellent,
long-term performance from the insulation. |
In fact, XPS offers exceptional performance in plaza
and protected membrane (PMRA) roofing applications. XPS allows for:
- Excellent moisture resistance and stable long-term
R-value;
- Extending the life of plaza or roof, providing
protection of the membrane from ultraviolet deterioration;
- Protection of the membrane against weathering,
physical abuse and damage;
- Maintaining themembrane at a relatively constant
temperature, thus minimizing effects of freeze-thaw cycling and
excessive heat;
- Reduced installation, material and repair expenditures;
and
- Easy removal and re-installation of ballast and
insulation.
