Differences Between PVB Standard and PVB Silence

Both PVB Standard and PVB Silence are high performance laminated glass interlayers, but they serve different primary purposes and provide distinct benefits. Here’s a breakdown of the differences:

Material	PVB Standard	PVB Silence
Primary Purpose	Security and Safety	Sound Insulation
Main Benefit	Enhances glass strength, safety, and security by holding glass together upon impact.	Reduces external noise and improves acoustic comfort by absorbing sound vibrations.
Security Features	Provides impact resistance to prevent glass shattering in case of break-in or accidents.	Primarily focused on reducing noise, but offers some security benefits due to the laminated structure.
Noise Reduction	Offers some noise reduction but is not designed for high acoustic performance.	Superior sound insulation – blocks and absorbs sound, significantly reducing noise from outside.
Use in Glasscraft Products	Used in Hytherm Security, Hytherm Security Extra, and Hytherm Solar Security for safety and impact resistance.	Used in Hytherm Silence to provide quietness and sound comfort in addition to some security benefits.
UV Protection	Blocks UV rays to protect interiors from fading.	Also blocks UV rays, offering protection for furnishings.
Durability	Enhances durability against impacts, extreme weather, and accidental damage.	Offers increased durability while improving acoustic comfort.
Primary Application	Ideal for high risk areas where security is paramount, such as homes, businesses, and windows in high security areas.	Best suited for noise sensitive environments, such as offices, residential areas near busy roads, or urban settings.

Which One Should You Choose?

PVB Standard is ideal when security, safety, and impact resistance are your main priorities, especially in areas where glass protection from breakage or break-ins is essential. It’s used in our Hytherm Security products.

PVB Silence is the best choice when you need excellent sound insulation and a quiet, comfortable environment. It’s used in Hytherm Silence for noise sensitive spaces.

If you need both security and sound insulation, you may want to combine different interlayers in your glazing, depending on your specific needs.
