Design Characteristics and Energy Efficiency Of Impact Windows

 

The modern impact doors and impact windows in Fort Lauderdale homes can be seen and found easily as these provide immense security and protection against the hurricanes. The impact window consists of a glass that is resistant to shattering which is secured and fastened to one very heavy aluminum frame. The windows have 2 layers of tempered or annealed glass which are bonded to an inner layer of PVB or Poly Vinyl Butaryl. This PVB is a plastic film that may have a thickness varying from .015 inch to .090 inch. The film prevents the 2 outer glass layers from shattering when they are broken by an external or internal impact. This is so because the broken glass pieces remain attached to the middle PVB layers and does not flies in the influence of the high-speed winds causing physical as well as economic losses. In comparison to the impact glass windows, the older and standard glass windows are made up a single layer of standard floating glass. The glass, when broken, can fly in the form of sharp shards and cerate dangerous temporary living conditions.

Testing And Certification

Only those impact windows are considered certified who meet the testing specifications of ASTM or American Society for Testing Materials. Homes in Florida have developed in their security aspects with successive phases of storm and hurricane destruction. They are now required to have a proper elevation level from the ground and must also have impact windows for protecting their homes against flying debris, according to the new country building code laws. Hence, impact windows in Florida homes are a necessity according to the Florida Building code.

Be Sure

While purchasing a new impact window when you are on a home renovation project, ask the window dealer to offer you an NOA or Notice of Acceptance that is issued by the Miami Dade County. The NOA document provides you with specific information relating to the materials, parts, dimensions, accessories apart from providing you the installation guidelines.  NOA  certification will also provide you information whether your chosen product has passed the impact resistance test successfully or not.

Missile Test

You will find two types of impact-resistant windows listed in the NOA. One that passes the small test and the other that passes the large missile test. The large missile test consists of firing of a 6 foot long and 9 pound-in-weight wooden lumbar cannon that is fired at the impact window at the speed of 50 feet per second. The large missile test is for the structures that have a size of 30 feet or more. The small missile test consists of firing of 30 roof gravel pieces at a speed of 80 feet per second. This test is for structures that height of below 30 feet.
