These are general specifications suitable for most projects. We will gladly create a comprehensive spec and estimate based on your specific project needs.
 

PLEATS: Box pleated 12" on center. Pleats are formed using 6" to 9" of additional fabric, folded and shaped to form box pleat, then stitched to Heavy 3" Black Poly Pro webbing reinforcement at tops of curtain/boarder using two rows of stitching.

SEAMS: All selvages to be removed and seams are to be surged (over locked).

SIDE HEMS: Main/Proscenium Curtain to have 12" side hems on and off stage so you can rotate them if needed due to wear. Side hems to be 3". Valances/boarders 3" bottom hems.

WHEN LINED: Lining in same fullness as face fabric, sewn in at the top, sides held to face fabric by 6" flat twill tape spaced 12" apart to hold lining to face fabric. Twill tape also holds fabric at seams inserted into the bottom hem to prevent pillowing. Lining hemmed at bottom and lining to finish 2" shorter than face fabric.
 

LABELING OF ALL UNITS: Sew in labels on off stage bottom hems. Labels to note the size and location of the unit along with the NFPA Flame requirements.
 

F.R. COTTON vs. I.F.R. POLYESTER
 

Both the Cotton and the polyester will pass the 701 NFPA flame requirements.
 

Intrinsically Flame Retardant Polyester Fabric (I.F.R. Polyester)
 

• Flame proofing is intrinsically vs. topically treated.

• Flame Proofing is for the LIFE of the fabric. It will not dissipate due to usage, handling and cleaning.

• The chemicals can NOT come of on the hands of the students and stage hands.

• Fire marshal and or Health & Safety inspector may NOT ask to have the fabrics cleaned, retreated and recertified for F.R. after a hand full of years. Just present them the IFR Certificate.

• Polyester will NOT tear easily at all . In fact it is very hard to tear!!

• Polyester is washable it will NOT stain or leave a water ring from chemicals.
   

Flame Retardant Cotton Fabric (F.R. Cotton)
 

• Flame proofing is topically treated. Not Intrinsically.

• Flame Proofing will dissipate due to usage, handling and cleaning.

• The chemicals can come of on the hands of the students and stage hands.

• Fire marshal and or Health & Safety inspector may ask to have the fabrics cleaned, retreated and recertified for F.R. after a hand full of years.

• Cotton will tear very easily regardless if fabric is new or old.

• Cotton is washable yet it will stain very easily and leave a water ring from chemicals.

• Cotton fabric will shrink up from the curing of the F.R. treatment.
