Aesthetic appeal from a positive pressure door? Only at VT!
VT Industries has responded to positive pressure fire door requirements (UBC 7-2-1997) with construction that addresses industry standards while maintaining the visual integrity of the total opening.
VT provides Category A fire doors as classified by Intertek/Warnock Hersey to meet the aesthetic needs of your overall building design. Unlike exposed edge-sealing systems that detract from the visual appearance of the door or its frame, VT's concealed intumescent provides you with the same seamless elegance as our non-rated doors.
The VT Advantage
- Maximum Sizes for Neutral Pressure Doors: Singles up to 4-0x10-0. Pairs up to 8-0x10-0.
- Maximum Sizes for Positive Pressure Doors: Singles up to 4-0x9-0. Pairs up to 8-0x9-0.
Design
- Positive pressure doors meet Intertek/Warnock Hersey Category A guidelines - "No additional edge-sealing system is required"*
*Where smoke and draft control is required by local codes ("S" rating) an approved smoke gasketing must be applied around the frame perimeter.
How to specify
- Where UBC 7-2-1997 requirements for positive pressure must be met, doors shall include all requirements as part of door construction per Category A guidelines as published by Intertek/Warnock Hersey.
- No intumescent is allowed on the frame.
- Only smoke gasketing applied around the perimeter of the frame to meet the "S" rating is permissible.
