The fixed costs of operating a business continue to increase each year, and energy costs are no exception. The only way to lower your energy costs is to reduce your consumption, but that doesn’t mean you should sacrifice your employees’ comfort! You’ll want to ensure that your HVAC system is performing at maximum efficiency and find other ways to tighten your belt. A zoned comfort system is a good option for a large office campus, and proximity lighting makes a small but noticeable difference. The final step is reducing energy waste. You can save up to 10% on energy costs by installing weather stripping around your windows and doors!

If you’ve ever been frustrated with conventional weather stripping, you’re not alone! Adhesive or screw-on weather stripping deteriorates easily and is difficult to replace. But National Custom Hollow Metal can give you a quote on custom-built two-part kerf frames built to your specifications. Our kerf frames feature a 3/32” gap that holds our Elon 490 kerf foam weather stripping. The weather stripping forms a tight seal around your doors, and you and install it in minutes without any special tools. When it deteriorates, you can order replacement weatherstripping at any time.

We most typically configure our kerf frames to fit 3068, 3070, or 3080 openings, but we can also manufacture doors and frames in custom sizes to your specifications. 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, or 14-gauge 304 or 316 stainless steel or A-60 or G-90 galvanneal steel.

We include free Quik Ship Service with all orders and expedited shipping options for distributors with tight deadlines. We’re always a phone call away if you have questions, and your satisfaction is always guaranteed!
