Pemko Perimeter Gasketing

Key Features

• Aluminum retainer channels with 1/4" wide profiles and 1-1/8" heights accommodate various compressible inserts for frame compatibility.
• Multiple insert materials including Pemkoprene® (303DPK), vinyl (303DV), and silicone for astragals (355-CS), offering choices for sound, fire, or weather performance.
• Dark bronze anodized and clear anodized finishes that coordinate with commercial frames and hardware aesthetics.
• Standard lengths such as 84" for astragals and custom-cut perimeter sections to fit door heights precisely.
• Fire-rated and smoke-labeled options suitable for labeled assemblies when paired with continuous pressure plates or meeting edge seals.

Key Benefits

• Superior air and weather sealing reduces energy costs and prevents drafts in high-traffic entrances and corridors.
• Acoustic isolation blocks sound transmission between spaces, ideal for offices, healthcare, and hospitality environments.
• Light and dust control with flexible, high-durometer inserts that compress without permanent set.
• Easy maintenance through field-replaceable inserts that extend gasket life without removing the aluminum retainer.
• Smooth door operation with low-friction profiles that don't interfere with latch engagement or closer function.

Applications

• Commercial storefronts and entrances where perimeter gasketing seals aluminum doors against wind-driven rain and air pressure.
• Healthcare and education facilities requiring smoke and sound gaskets on patient room, classroom, and corridor doors.
• Hospitality and multifamily properties using T-astragals on meeting edge pairs for light and acoustic separation.
• Fire-rated interior openings with Pemko gasketing maintaining label integrity while providing continuous sealing.
