Therma Hold Thermal Doors help hold the line in preventing cold transfer from outside to the inside. Think of Therma Hold when looking to improve efficiency and comfort while preventing condensation and frost.

Lab Tested NCHM Thermal Rating Level Per ASTM C1363-19

Sample Tested 35 ¾ “x 83 ¼” Flush Door with a 2” Face 3-Sided Door Frame

Steel Gauge Tested Door & Frame – 14 GA Operable with Butt Hinges & Cylindrical Lock

NCHM Therma Hold Door (ICO) Core and Thermal Break Frame when partnered with NGP Thermal Thresholds, Seals and Sweeps reduce the U Value and help decrease yearly Commercial Building Energy Costs. Think of Therma Hold when looking to improve efficiency and comfort while preventing condensation and frost

To Achieve Best Desired Thermal Resistance Outcome Results

1. Insulate Thermal Brake Frame Cavity with Fiberglass or Mineral Wool
2. Use Polyurethane (ISO) Core 14 GA Stainless Steel or A60 Galvanneal
3. Caulk Frame Edge to adjacent wall
4. Apply Gasketing Door to Frame preventing air flow (gasketing optional; provided by others)
5. Include Thermal Break Threshold and Sweep
