People living in the southeast are no stranger to seasonal weather extremes. In fact, during certain times of year, people will often run both their heating and air conditioning on the same day. Unfortunately, what this means is high utility bills year-round. Improving the efficiency of your HVAC systems is a great way to keep your employees and customers comfortable, while also managing your energy costs.

National Custom Hollow Metal has been providing premium quality stainless steel doors and frames to distributors for over 40 years, and our commitment to customer satisfaction is second to none. Whether it’s our top-selling DefendDoor line of doors and frames, our TrustShield Lead-lined products, or our new Ballistic and Sound Transmission Control (STC) doors, everything that you order is manufactured to your exact specifications by the most talented and well trained craftsmen in the industry. We’re also proud to offer two part kerf frames with interchangeable weather-stripping.

Our kerf frames are most typically configured to fit a 3068, 3070, or a 3080 opening, but can also be manufactured in custom sizes. The jambs are configured to a 5 ¼” minimum depth for a 1 ¾” door, or a 4 ⅞” minimum depth for a 1 ⅜” door, up to a maximum depth of 20”. Our kerf frames can be built from 16, 14, or 12 gauge 304 or 316 Stainless steel or A-60 or G-90 Galvanneal Steel.

The frames feature a 3/32” frame gap to receive Elon 490 kerf foam weather-stripping, which forms a tight seal around the door to prevent drafts. Your heating and air systems won’t have to work so hard to compensate for the sudden temperature changes that occur each time that a door is opened, and you should see significant energy savings over time. The weather stripping is much more durable and easier to replace than conventional adhesive or screw-on weather-stripping, and ordering replacement weather stripping from NCHM couldn’t be easier!

At NCHM, we understand that our clients have tight deadlines, which is why we offer Quik Ship service standard on all orders, as well as expedited shipping options.
