Excellent for Noise Reduction Systems!
By design "Sheerframe" doors and windows will give you trouble free years of service virtually with no maintenance. Our exclusive PVC compound is highly resistant to impact, discoloration and will not pulverize or become brittle. In laboratory tests our windows virtually did not show any change in their appearance after 12,000 hours of exposure to accelerated U. V. rays. As a matter of fact, our windows are certified under AAMA\ NDWA 101\I.S.2. This means an exceptionally low water and air infiltration, high structural strength and low heat emissivity and sound transmission (noise stays on the outside).

  
 

Features:

• Exclusive PVC compound highly resistant to impact

• Thermally fusioned corners

• Pivot ventilator for easy cleaning from the interior

• Low thermal and sound transmission class

• tested to 160mph wind loads

• Virtually maintenance free

PCV windows will make your residence more effi-cient due to our exclusive insulated multiple chamber design and by thermally fu-sing the corners.
Marva's vinyl windows have a 20 year warranty against discoloration due to our exclusive PVC compound that "reflects" U.V. rays.
