PERFORATED RADIANT BARRIER ALLOWS
MATERIAL
TO BREATHE - A CONDENSATION KILLER
 Moisture
condensation can be a real concern when a radiant barrier is installed
on the attic, particularly in extremely humid or cold climates. Water
vapor in the air can condense on the surface of the roof sheet. Condensation
of water could lead to the following problems:
| 1) |
the
existing insulation can become wet and lose
some of its insulating value, |
| 2) |
water
spots can appear on the ceiling, and |
| 3) |
under
severe conditions, the ceiling framing can rot. |
To
minimize the risk of water damages to ceilings or risk of corrosion
due to condensation under roofs, a micro-perforated radiant barrier
could substantially assist in the reduction of condensation and prevent
potential moisture problems.
Perforated materials are suitable for many types of retrofit applications
and for some new construction in places of high humidity and in areas
of cold climate.
However, PE bubble foil and PE foam foil cannot be perforated and kraft
paper foil is also not suitable for perforation since it can absorb
moisture easily. Our micro-perforated radiant barrier is a breathable
material; in other words, it can allow harmful moisture and humidity
to escape and eliminate condensation.
