Based on Soudal's FLEXIFOAM® technology, it cures to a flexible, permanently airtight seal that moves with the joint — making it the right choice for high-performance installations where a standard rigid foam would crack and fail over time. Recommended for all A, A+ and A++ rated windows and doors. 750ml gun grade can.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhy Window and Door Foam Isn't the Same as Standard PU Foam\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eStandard expanding foam is rigid once cured. That's fine for filling static voids — but window and door frames aren't static. They expand and contract with temperature changes, flex under wind load, and move slightly as buildings settle. A rigid foam seal around a frame will eventually crack at the edges, breaking the airtight layer and allowing heat loss, draughts, and potentially moisture ingress.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eSoudafoam Window \u0026amp; Door SWS is engineered for exactly this challenge. Its FLEXIFOAM® formulation gives the cured foam three times the flexibility of standard PU foam, allowing it to follow the movement of the joint across its lifetime without cracking or delaminating. The seal stays airtight whether the frame is freshly installed or twenty years old.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eAirtight and Acoustically Rated\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eOnce cured, Soudafoam Window \u0026amp; Door SWS is completely airtight — tested and certified to RAL MO-01\/1 and DIN 18542, the standards used to verify airtight window and door installations. It also delivers strong acoustic performance, achieving a sound reduction rating of 63 dB to ISO 717-1, making it a genuine performance product for noise-sensitive installations rather than just a gap filler.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThermal conductivity is 34.5 mW\/m·K, in line with the insulation performance expected from a premium window installation foam.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eGun Grade for Precision Application\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eSoudafoam Window \u0026amp; Door SWS is a gun grade product — it requires a professional foam gun for application. The gun format gives significantly better control than straw-applied foam: precise bead placement, consistent fill depth, and the ability to stop and restart cleanly. For window and door installations where accuracy matters and waste needs to be minimised, gun grade is the professional choice.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe can uses Soudal's Duravalve system, which maintains optimal yield throughout the shelf life of the can — even if stored or transported horizontally.
