Traditional home contractor use some old methods for the
insulation of new homes. After completing the construction process some
contractor use traditional method for insulation. They install above ceiling
insulation and use attic ventilation to reduce or completely remove the
moisture present in the building. With attic ventilation unfiltered air move
inside the roof and dust in the air stuck in attic cause the mess over the
insulation. This dust and moisture collectively affect the R-value of the
cellulose or fiberglass material used as insulation. Worms or insects occupy
the space and case the blockage of attic and because of the blockage of the
attic. Because of the blockage of attic temperature of that place may fall or
rise to extreme cause the damage to things placed on that specific place.
The new idea for the insulation of the spry foam is to
install it all over the home. This makes an envelope completely over the home.
Thus the HVAC and duct are in the controlled environment and this improves the
performance of the HVAC. Spray foam insulation stop the leakage of heat or cold
from the building. This reduces the workload for the HVAC systems and helps to
maintain the internal temperature.
But for the traditional contractor it is a difficult to
follow because they somehow still follow the concept don’t build a home too
tight. They think that it is important to leave the space for air to come in
but for the spray foam industry this is a standard to insulate the home
completely leave the ventilation work for the heat exchanger that do the task
of filtering the air first and after that cooled or warmed the air. Fresh air
comes in through the HVAC system.
