Expanding Foam Insulators for Preventing Heat Loss
Well-known products like polyurethane foam and Styrofoam are widely used for
insulation jobs. Their special qualities make them perfect for reducing heat
loss. These materials have low density as foam is formed by trapping air bubbles
in its liquid and solid form. Therefore, they function as ideal insulators and
flotation devices.
When applied, expanding foam insulators are transformed into barriers that keep
the heat inside. They help reduce not only the conductive flow of heat, but, by
adding a reflective barrier, they also slow down the radiant heat flow.
Fiberglass, polyurethane foam and polystyrene and cellulose insulation can be
used. The product named spray applied polyurethane foam is the most widespread.
Characteristics of Expanding Foam Insulation
Expanding foam insulation is very popular due to its qualities of being
inexpensive and easy to maintain. As a plus, there are no additional measures to
take when applying as the foam is sprayed directly on the surface that needs to
be insulated. Other features of expanding foam insulation is resistance to
moisture, insects and temperature fluctuations. Expanding foam insulation is
impermeable to water due to its closed cell structure. Not only water is kept at
a distance, but also drafts and dirt. This type of insulation is widely used for
its weather proof features and it helps in reducing heat loss in buildings.
Expanding insulation foam is also environment friendly and energy efficient.
Installing Expanding Foam Insulation
Installation of expanding foam insulation is not a very complicated operation.
First, holes are drilled in the vertical column of blocks, through the mortar
joints, making eight inches gaps. The foam is injected in these vertical columns
and, due to its traits, it rapidly fills all the empty spaces in all directions.
The insulation expands through the joints, getting to the adjacent cells, and
not even the smallest hole in the wall remains unfilled. When the operation is
finished, the wall is completely sealed. The foam covers all the empty space
when the extra substance appears on the exterior in the form of little
mushrooms. All the excess is eliminated with a small broom and the holes are
covered with mortar. Some precautionary measures are to be taken when working
with expanding foam insulation, like wearing protective gloves, protective eye
wear and avoiding contact with skin, eyes and clothing. |
