INGADA™ SR-M25 Fenestration Silicone Sealant – High-Performance Window Glazing
Sealing Where Windows Meet Walls
-
The Problem: The gap between a rigid wall and a window frame is a “hot zone” for air leaks and water damage due to different expansion rates.
-
The Solution: SR-M25 acts as the “perfect bridge,” absorbing the micro-movements of the building while keeping the elements outside where they belong.

-
±25% Movement Capacity: Specifically engineered for the interface between window/door frames and building substrates.
-
Dual Adhesion Technology: Provides a powerful bond to both porous (concrete, brick) and non-porous (PVC, aluminum) materials.
-
Mold & Mildew Resistant: Formulated to prevent fungal growth in damp environments, maintaining a clean and aesthetic seal.
-
Air & Water Infiltration Barrier: Enhances building energy efficiency by creating a continuous, airtight perimeter seal.
-
Low Modulus Flexibility: Bridges minor substrate cracks without transferring stress to the window assembly.
