FAQ

They can be painted or they can be replaced, but all replacements of fire labels have to be done under a field service inspection.

The E6 has equal positive and negative pressure label capabilities as the 707 except for limitations due to availability of the E6 steel.

Yes, the limitations for louvers are shown on the Fire Labeled Door Chart in the CURRIES Product Brochure.

Yes, UL only with ½" UL panel up to 90 minutes.  Maximum door size is 4080, maximum panel size is 3030 (FG2 allowed), ¾" stop height required. 

It is located on the face of the panel. 

No. 

We do not have a separate 450° temp. rise fire label, but the 250° temp. rise rated 727 door can be used in any application calling for 450° or 650° temp. rise rating.

Our 737 was tested flush and glazed to UL752, Level 2 bullet resistance.  We don’t have certification to use a mail slot or viewer in the 737 door. 

Yes, within limitations of wood door manufacturer’s label procedures.

Listed and labeled kits can be used with our doors.  Check with the window kit manufacturer for installation details and approved glazing with their kits.

Bonderizing is a trade name for phosphatizing.  CURRIES uses specialized equipment to apply an iron phosphate coating (phospahtizing) to the steel during the cleaning process before painting to improve paint adhesion and increase rust resistance. 

This value has not been defined through testing.  The value may approach the STC of a 747 single if a good quality sound seal system is used in the paired assembly.

The Type 8 kit can be used in a 727 door.  It is probably specified because a temperature rise glazing is being used by the customer that requires a wider pocket.  Temperature rise rating is retained if the area is 100 square inches maximum and subject to approval by local jurisdiction.

Yes, but we recommend that the customer purchase a flush pull manufactured with specialized tooling to eliminate the sharp edges and provide a more aesthetic finished look than we can provide on an integral pull.

We have specially prepared doors and frames to receive cladding, but we do not apply the cladding.  Applying cladding to CURRIES fire rated doors and frames voids the fire label. 

None of our doors work well with a powder coat finish due to the high temperature to cure the paint.  All doors have body filler on the door edge to fill welds or seams.  The body filler tends to crack and fall out when heated above 300°F.  If a customer powder coats a door CURRIES is not responsible for the effect on the body filler.  The 707 door adhesive and polystyrene core will both be destroyed at these temperatures.  Only the 747 door should be considered for applying a powder coat finish, but CURRIES will not warrant the outcome. 

The correct way would be to drill all of the welds on the top end channel and remove the closer reinforcement along with the end channel.

The customer needs to supply the desired design pressure for each opening.  Our product is tested to a maximum design pressure.  The wind load is converted into a design pressure with adjustment factors for terrain, height above grade, importance factor, and opening location in the building.  These may affect the design pressure by a factor of 4.

Exterior grade Pyrostop requires a 1-11/16" minimum pocket width. We can only offer this in a 2" thick door. The exterior grade Pyrostop can be offered in a 1-3/4" door because the pocket is less than 1-5/8".

Yes, these doors can be supplied in any opening height increment (e.g. 6’10½") between these heights.

Yes we can, it has to be our type 1 kit.
