SGP Laminated Glass

SGP Laminated Glass 

SGP Laminated Glass refers to a type of safety glass that incorporates SentryGlas® Plus (SGP) ionoplast interlayer, a high-performance material developed by DuPont. This interlayer is sandwiched between two or more glass panes, creating a strong, durable, and safe laminated glass product.

1) Superior Strength & Durability

SGP interlayer is significantly stronger than traditional PVB (Polyvinyl Butyral), offering higher stiffness and load-bearing capacity.

Resists penetration and deformation under impact.

2) Enhanced Safety & Security

Even when broken, the glass fragments remain bonded to the SGP interlayer, reducing injury risks.

Provides resistance against forced entry, blasts, and ballistic threats.

3) Optical Clarity & UV Stability

Maintains excellent transparency over time.

Blocks up to 99% of UV rays, protecting interiors from fading.

4) Weather & Moisture Resistance

Unlike PVB, SGP is less prone to moisture absorption, preventing delamination.

Performs well in extreme temperatures (-40°C to 80°C).

5) Structural Applications

Used in glass floors, stairs, canopies, and facades due to its high load resistance.

Suitable for hurricane-prone and seismic areas.

SGP laminated glass is a premium choice for applications requiring high strength, safety, and durability. While more expensive than PVB, its performance benefits make it ideal for demanding architectural and security uses.

Advantages of SGP Laminated Glass

SGP (SentryGlas® Plus) laminated glass offers superior performance compared to traditional PVB or EVA laminated glass. Here are its key advantages:

1. Exceptional Strength & Structural Performance

5x Stiffer & Stronger than PVB – Reduces glass deflection, making it ideal for:

① Glass floors, stairs, and beams (handles heavy loads without sagging).

② Large-span facades & canopies (better wind load resistance).

③Higher Post-Break Strength – Glass fragments remain tightly bonded, maintaining structural integrity even after cracking.

2. Enhanced Safety & Security

1) Impact & Blast Resistance – Used in:

① Hurricane-prone areas (passes Miami-Dade TAS 201-203).

② Bullet-resistant & forced-entry-resistant glazing (UL 752 certification).

2) Shatterproof – Unlike tempered glass, it doesn’t explode into tiny pieces.

3. Better Durability & Weather Resistance

① Moisture-Resistant Interlayer – Unlike PVB, SGP won’t delaminate in humid climates.

② UV Stability – Blocks 99% UV rays, protecting interiors from fading.

③ Wide Temperature Range (-40°C to +80°C) – Performs well in extreme heat/cold.

4. Optical Clarity & Aesthetic Benefits

① Crystal-Clear Transparency – No yellowing over time (unlike some PVB).

② Thinner & Lighter – Achieves same strength with less thickness vs. PVB.

③ Compatible with Decorative Glass – Can be used with printed, tinted, or curved glass.

5. Low Maintenance & Long Lifespan

① No Edge Sealing Required (unlike PVB, which can degrade at edges).

② Resists Scratching & Chemical Damage – Easier to clean and maintain.
