1) What is the Pemko S773 adhesive-backed fire/smoke gasketing used for?
The S773 provides fire and smoke sealing for doors and frames. It creates an effective barrier when doors close, preventing smoke migration and maintaining fire ratings. Commonly used in commercial buildings, hospitals, and educational facilities.
2) What door types and frame materials is this gasketing compatible with?
Works with steel, wood, and aluminum doors and frames. Compatible with hollow metal doors, solid core wood doors, and composite fire doors. Verify surface is clean and smooth for proper adhesion.
3) How is the adhesive-backed design installed?
Peel backing and press firmly onto frame or door edge. Clean surface with degreaser first. Apply at room temperature for best adhesion. Position carefully as repositioning may reduce adhesive strength.
4) What finishes and colors are available for the S773?
Typically available in black or gray intumescent material. Color may vary by manufacturer production run. Contact supplier to verify current finish options for your specific application.
5) What fire rating does this gasketing provide?
Designed for use in fire-rated door assemblies. Specific rating depends on complete door system testing. Consult fire door manufacturer specifications and local code requirements for rating verification.

8) What gap size does the S773 accommodate?
Gap accommodation varies by gasket thickness and compression. Measure actual gap between door and frame when closed. Select thickness to ensure proper compression without binding door operation.
9) How do you maintain and service this type of gasketing?
Inspect regularly for gaps, damage, or detachment. Clean gently with mild detergent. Replace sections showing wear or poor adhesion. Avoid painting over gasket as this may affect fire performance.
10) What are similar models or alternatives to the S773?
Other Pemko intumescent gaskets include different profile shapes and mounting methods. Consider screw-in or kerf-mounted options if adhesive application is not suitable. Verify fire testing compatibility before substituting.
