Home / News / Industry News / What types of glass are used for the shower screen doors, and how do they impact durability and safety?
Shower screen doors commonly use several types of glass, each affecting durability, safety, and aesthetics differently:
1. Tempered Glass
Description: Tempered glass is heat-treated to increase strength. It is approximately four to five times stronger than regular glass of the same thickness.
Durability: Highly resistant to impact and thermal stress, making it ideal for shower doors that may face frequent use and temperature changes.
Safety: When broken, glass shower screen door shatters into small, blunt granules rather than sharp shards, reducing injury risk.
2. Laminated Glass
Description: Laminated glass consists of two or more glass layers bonded with an interlayer (usually polyvinyl butyral, PVB).
Durability: While not as impact-resistant as tempered glass, laminated glass holds together when cracked due to the interlayer, preventing shards from scattering.
Safety: Provides additional security against breakage and can block UV rays. It is less likely to cause injury because the interlayer keeps fragments adhered.
3. Frosted or Etched Glass
Description: Frosted glass is created by sandblasting or acid etching clear glass to produce a translucent, matte finish. It can be either tempered or laminated underneath.
Durability: The underlying glass type determines the durability. Frosting itself does not weaken the glass but can slightly reduce transparency.
Safety: Frosted tempered glass retains the same shattering safety properties as clear tempered glass. It provides privacy without compromising structural safety.
Summary of Impact on Durability and Safety
| Glass Type | Durability | Safety Features | Common Use Cases |
|---|---|---|---|
| Tempered | High impact and thermal resistance | Breaks into small blunt pieces to prevent injury | Most common for shower doors |
| Laminated | Moderate impact resistance | Holds shards in place when broken, enhanced security | Used when added safety or soundproofing is needed |
| Frosted (Tempered or Laminated) | Depends on underlying glass | Provides privacy and maintains safety features of base glass | Privacy-focused bathroom designs |
Choosing the appropriate glass type depends on the balance between safety requirements, aesthetic preferences, and functional needs like privacy or sound reduction. Tempered glass is the most widely used due to its combination of strength and safety, while laminated glass is preferred in areas needing extra security or sound insulation. Frosted glass is often selected when privacy is a priority.
