Four-Treasure Works

The Four-Treasure Works adds outer and inner frame rubber weatherstrip replacement to the Safety Accessories Works, providing comprehensive waterproofing. Deteriorated seals are a primary cause of window-edge leaks; regular replacement prevents rainwater entering the home and protects walls and interior finishes.

We use high-density silicone rubber weatherstrips — heat-resistant, acid-resistant and pressure-resistant — with a flexible design for lasting sealing performance. The Four-Treasure Works is especially recommended for units facing the sea or typhoon-prone directions.
