“Is your window ready for the monsoon’s mood swings...?"
🌧️ Water Drainage Slot & NRV Valve Mechanism:
🔹 Purpose:
Aluminium windows are exposed to rain, humidity, and condensation. Without proper drainage, water can accumulate inside the frame, leading to leakage, corrosion, and fungal growth.
🔹 Drainage Slots:
These are precision-cut openings at the bottom of the window frame or sash.
They allow accumulated water to escape from the internal chambers of the profile.
Positioned to use gravity and airflow for efficient drainage.
🔹 NRV (Non-Return Valve):
A one-way valve integrated into the drainage path.
Prevents water from flowing back into the window during wind-driven rain or pressure surges.
Ensures that water exits the system but never re-enters—especially useful in high-rise or coastal buildings.
✅ Benefits:
Keeps interiors dry and mold-free.
Extends the lifespan of aluminium profiles and hardware.
Reduces maintenance and service calls.
🛡️ EPDM Gaskets: Thermal & Acoustic Insulation:
🔹 What is EPDM?
EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber known for its:
High elasticity
UV and ozone resistance
Long-term durability in extreme temperatures
🔹 Thermal Insulation:
EPDM gaskets seal the gaps between sash and frame, preventing air infiltration.
Reduces heat transfer between indoor and outdoor environments.
Helps maintain consistent indoor temperatures, lowering HVAC energy consumption.
🔹 Acoustic Insulation:
EPDM’s dense, flexible structure absorbs sound vibrations.
Blocks external noise from traffic, construction, or urban environments.
Enhances indoor comfort and privacy—especially in offices, hospitals, and homes near busy roads.
✅ Benefits:
Energy-efficient and eco-friendly
Noise reduction up to 30–40 dB depending on system design.
