Therma Hold frames are suitable for all types of wall construction and offer superior protection against the spread of condensation and frost on your exterior masonry openings. They 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. Therma Hold doors are also feature a core that will decrease the U value for the enclosure.

Like all NCHM products, Therma Hold doors are custom-built to your specifications in your choice of multiple frame profiles, including a 3-sided door frame or 4-sided single lite window frame. The thermal gasketing is secured every 12” with #8 sheet metal screws, and for best results, we strongly recommend installing NGP thermal thresholds, seals, and sweeps to form a tight seal around the thermal brake.
