Businesses often ramp up production in order to scale certain fixed costs, but utility costs predictably increase any time a company expands. Energy companies have the freedom to increase rates any time they see fit, and the only remedy for higher bills is lowering consumption and reducing waste. If you’re interested in improving overall energy efficiency in a building without sacrificing the comfort of the people working inside, National Custom Hollow Metal can give you a quote on Therma Hold Doors and Frames in two hours or less!

Therma Hold thermal frames help hold the line by preventing cold transfer from outside to the inside, and they’ll help you prevent the spread of condensation and frost on your exterior masonry openings. They’re suitable for all types of wall construction, and we offer multiple frame profiles; we can give you a quote for a 3-sided door frame or 4-sided single lite window frame with a 3’0” x 7’0” single frame or 7’0” x 7’0” standard pair frame configuration. Our stainless steel Therma Hold doors feature a polyurethane core, and our galvanneal doors can be custom-built with your choice of a polyurethane core or a polystyrene core with up to a 3-hour Warnock Hersey fire rating.

Therma Hold doors and frames feature a two-part construction that separates both sides of the frame jamb and header along the stop, and the barrier prevents temperature transfer from outside to inside. The thermal gasketing is secured every 12” with #8 sheet metal screws, and we strongly recommend installing NGP thermal thresholds, seals, and sweeps to form a tight seal around the thermal brake. Therma Hold doors will significantly decrease the U value for the enclosure, and they’re corrosion-resistant and maintenance-free.
