Garware HHR Grey 70 is a popular High Heat Rejection (HHR) window film by Garware Hi-Tech Films, known for its superior heat-blocking, UV protection, and grey tint that balances light transmission (around 70%) with heat reduction, making it ideal for homes and buildings to cut glare, save energy, and protect interiors without sacrificing too much natural light. It uses nano-technology (organometallic particles) for long-lasting performance, offering high Total Solar Energy Rejection (up to 90%) while maintaining good outward vision.
Key Features:
- High Heat Rejection: Blocks significant solar heat, reducing air conditioning costs.
- UV Protection: Blocks harmful UV rays, preventing furniture fading.
- Grey Tint: Offers a modern look and reduces glare with good light passage.
- No Metal Content: Uses nano-particles for durability and non-interference with signals (like mobile/GPS).
- Energy Efficiency: Helps maintain cooler indoor temperatures.
- Safety: Adds strength to glass, preventing splintering on impact.
Performance (Approximate Specs):
- Total Solar Energy Rejected (TSER): ~90%.
- Visible Light Transmittance (VLT): ~69-70% (meaning it lets in about 70% of visible light).
- UV Blocked: <1% (blocks almost all UV).
In essence, it’s a high-performance sun control film for glass that offers a comfortable, energy-efficient indoor environment.
