Firemiser Insulated Fire Door

Model ERD20

When you need both fire and environmental protection, you need a Firemiser Insulated Fire Door.  This includes:

• Fire wall openings where the door is frequently closed and sound attenuation is desired
• Exterior openings that have fire-protection requirements
• Buildings that are designed for future expansion with an exterior wall planned to become an interior, fire barrier wall

The Firemiser Insulated Fire Door provides up to 4 hours of UL rated fire protection plus:

• Security – Rolling steel offers superior security for both internal and external openings
• Sound Attenuation - A Sound Transmission Class rating of up to 27 STC (based on testing a complete, operable door assembly) makes Firemiser's mineral wool insulated curtain an excellent choice to maintain fire wall integrity and reduce decibel levels
• Climate Control - Firemiser's insulated curtain yields an R-value of 5 that can be combined with full perimeter seals for use at exterior or interior openings whenever fire protection and environmental separation is required

Standard Sizes:

Standard construction covers openings up to 30’ wide, 22’ high.  

For openings that fall outside of standard construction sizes, please contact us.
