The traditional metal plenum box, positioned above the ceiling
grille, is expensive to produce, needs at least a team of two to
install and invariably has to be secured above the ceiling because
of its weight.
Now, a new lightweight and fully insulated product, the Prelite
Plenum, has been invented and is now being marketed by Prelite
Plenums Ltd.
The product is over 75 percent lighter than its metal equivalent
and can therefore simply sit on top of the ceiling grille. It is also made from a rigid phenolic insulation panel faced on both sides with a non-reflective reinforced back foil which prevents any light from reflecting off the inside of the plenum box through the grille.
Results to date show that Prelite Plenums can be installed in just
25 percent of the time of the traditional box and that a saving of up
to 20 percent is made on its installation cost; making them an
obvious choice for today’s fast-track air conditioning installations.

There is an obvious need for the industry to be more energy efficient and pay more attention to the ways in which energy is both used and wasted. Do you think we have the products on the market to meet our needs?
