GRANDOORS focuses on fire rated WOOD doorframes. Wood frames have historically been price prohibitive in fire ratings and forced the design community to regularly pair a wood door in a hollow metal frame.

Not anymore! - We have tested a much more affordable fire frame material, which now makes us more closely aligned in price to hollow metal frames when 20/45/60 minute ratings are required. We can be paired with ANY rated wood door on the market and can do paint grade or stain grade veneers.   90 minute wood door frames are also available when required.


Design teams, architects, and owners can now have a warmer, more consistent, and inviting door and frame option vs. the cold, institutional look of hollow metal frames.   


Our mission is summed up in 4 words:  Wood Door?  Wood Frame!


We also are pushing the boundaries on what is available on the market today.  We are proud to have tested and passed a 45 minute CONCEALED overhead Closer, which allows the closer body to be hidden in the doorframe header!  Ideal for Dorma and LCN overhead concealed closers, and a great, upscale option for condo or hotel unit entry doors.
