As we known the severe and complex nature of hurricane winds creates special challenges for buildings, for architects who must handle those challenges in hurricane and storm regions.Willing® HSF interlayers can be a critical first line of defense, Willing® HSF interlayers withstands these natural forces to help maintain the critical exterior protective screen. If broken by impact from wind-borne debris, the glass fragments bond firmly to the protective interlayer,continuing to safeguard building occupants and contents.
We lived normal circumstances, buildings are designed to allow wind to flow over the structure. During a hurricane, a fully intact building "cloth" allows wind to flow at, over and past the structure without damage. Preserving the building envelope, therefore, is among the most important steps to maintaining the integrity of the structure and ensuring non-destructive wind-flow during hurricane-force winds. During the sustained, strong winds of a hurricane, objects can be lifted and become an airborne missile or wind-borne debris. Large missiles, such as roof shingles and other construction materials, are common at heights up to 10m above grade; small missiles, such as roof gravel, are most prevalent at heights above 10m. When wind-borne debris breaks glass windows and doors, the building’s protective exterior “envelope” is compromised, potentially allowing strong winds to rush into the structure. These trapped wind forces then exert tremendously increased pressure on the roof and outward pressure on exterior walls, and can eventually cause total destruction.
Laminated glass with Willing® HSF interlayers in properly designed windows and doors can withstand the damaging impact of wind-borne debris and remain in the opening during the remainder of the storm and may even function as a barrier after being broken, helping to preserve the integrity of the interior until repairs can be made.
Hurricane force winds call for a level of protection that ordinary windows simply cannot live up to.Window and door systems made with Willing® Hurricane/Store force PVB interlayer laminated glass can offer protection from potential injury and property damage resulting from hurricane and storm. HSF-1 laminated glass window and door unit undergo rigorous testing to meet following wind borne debris standards for the large missile test by PA201,PA203 and ASTMs testing standards which are most important and stringent for hurricane storm resistances, the force defense and winds up to 150 MPH.
Willing® HSF-1 matches tough safety codes and standards, In order to meet hurricane building codes, commercial and residential window and door systems have to meet vigorous impact, simulating wind-borne debris and subsequent impact. Test procedures call for the entire system to resist wind-borne debris impact followed by pressure cycling. To comply with the test requirements for an impact-resistant product, the systems may also need to pass additional tests such as air and water infiltration, structural load and forced-entry resistance.it resists penetration by clinging to the tough plastic interlayer, helping the glass to remain in the framing system. This can help prevent injuries caused by dangerous flying shards of glass. All windows and doors made with Willing® HSF-1 laminated glass meet ANSI,ASTM E1886, ASTM E 1996.
Willing® HSF-1 laminated glass provide security protection at any moment . this tough glass can stand up to repeated blows from common burglary tools like bricks, bats, hammers and crowbars, the window and door systems made with Willing® HSF-1 laminated glass pass tough security glazing requirements by ASTM F588-85 standard for forced entry and glass retention and the ASTM F1233 for security glazing materials.
The Willing® HSF-1 in laminated glass can reduce irritating noise and acts as a filter that blocks out more noise than ordinary window glass as much as 55%, resulting in a quieter and more comfortable interior environment condition.
The Willing® HSF-1 in laminated glass can screen out more than 99% ultraviolet rays that most damaging UV rays, protect valued fabrics, furniture to degrade, because of damaging UV rays from sun can fade, leather to short age directly.
