The Fergmann Silicone system

Our silicone system is designed to solve the problem of draughts, moisture, noise, and dust penetration in metal casement or pivot style windows.

The hinges and catches are all serviced before applying the silicone treatment, ensuring that the windows open and close freely. The silicone when cured forms a draught, moisture, noise and dust proof gasket around the window, matching the exact contour of the original gap.
