SHOCKING RESISTANCE
Due to its homogeneous structure e its elasticity, the Comovent louvers made of rigid PVC have great shock resistance.
FIRE RESISTANCE
The PVC used in the Comovent louvers is not inflammable, carbonizing without flames, and is self-extinguished, and its carbonizing stop since the end of external fire occurs. The PVC do not spread the fire and do not leave fire drops.
CHEMICAL INERTIA
The Comovent louvers do not react to the major kind of chemical agents, industrial gases, common detergents, oils and greases, even the bacterias.
It exhibits no chemical reaction in contact with the construction materials, like cement, lime, gypsum, etc.
The PVC used in the Comovent louvers is formulated with anti-UV additive that filters the sun ultra-violet rays, which deteriorate and rot the common translucent PVC sheet.
The above values are typical and may vary depending of the essay machines, or location of tests.
The wings of the Comovent louvers may be fabricated with the following materials:
TRANSLUCENT PVC (several colors);
OPAQUE PVC (several colors);
ALUMINUM SHEET (several finishings);
GALBANIZED STEEL SHEET (plain or painted);
STEEL SHEET (several finishings);
STAINLESS STEEL SHEET;
COPPER OR BRASS SHEET;
POLYCARBONATE (compact/alveolar, several colors);
FIBERGLASS (several colors);
ACRYLIC SHEET (several colors);
MAXI-LUX.
MATERIALS FOR FRAMES
The frames of the Comovent louvers are fabricated with the following materials:
PVC PROFILE J (several colors);
ROLL-FORMED ALUMINUM SHEET (several finishings);
ALUMINUM PROFILE J (several finishings);
ALUMINUM PROFILE H (several finishings);
ROLL-FORMED GALVANIZED STEEL SHEET (several finishings);
ROLL-FORMED STAINLESS STEEL SHEET (several finishings);
ROLL - FORMED STAINLESS STEEL SHEET;
ROLL - FORMED COPPER OR BRASS SHEET.
