Utility companies have the power to raise rates as they see fit, and the only way to fight back is by reducing your energy consumption. This is often easier said than done, but you should start by identifying areas where energy is wasted. If you feel a draft around exterior doors when they’re closed, you’re paying more than you should to maintain your desired indoor temperature, and the extra costs can really start adding up! But the good news is that weatherstripping can make a huge difference, and our team at National Custom Hollow Metal is ready to give you a same-day quote for two-part kerf frames!

Every time an exterior door opens, conditioned air escapes and outside air rushes in, forcing HVAC systems to work overtime. Even doors that are closed promptly can be a hidden source of energy loss if the enclosure isn’t properly sealed. Kerf frames are designed to solve that problem. Each frame features a 3/32” gap that accommodates our Elon 490 kerf foam weatherstripping, creating a tight, consistent seal around exterior doors. Installing the weatherstripping only takes minutes and requires no tools, screws, or adhesives. For optimal performance, the weatherstripping should be replaced at least every two to three years, and we’ll send you automatic email reminders when it’s time to reorder.

Kerf Frames can be manufactured to your specifications from 16 or 14-gauge 304 or 316 stainless steel or from A-60 or G-90 galvanneal steel. Our most common configurations fit 3068, 3070, or 3080 openings, though we regularly produce custom sizes to meet exact project requirements. Jambs are configured with a 5 ¼” minimum depth for a 1 ¾” door or a 4 ⅞” minimum depth for a 1 ⅜” door, with maximum depths available up to 20.” All NCHM orders include free Quik Ship service, with a standard turnaround time of one week for frames. And if that’s not fast enough, we also offer expedited Hot Rush and Walk Thru service with shipping as soon as the following business day. And you can always order from NCHM with confidence, because we stand behind all orders with a one-year warranty!
