Introducing Log Gap Caps, the ultimate solution for enhancing energy efficiency in log homes. Designed to accommodate a wide range of log diameters from 6 to 11 inches, these pre-cut caps offer a uniform shape that seamlessly reduces air infiltration at the juncture of round logs and window/door trims. While it’s important to note that there are numerous log profiles available, our fit guidelines ensure a versatile application while allowing for tail trimming to achieve an optimal fit for smaller log profiles.

Crafted from a durable material that is resistant to mold, rot, and bacteria, Log Gap Caps provide long-lasting protection without compromising on performance. These caps are specifically engineered using ¾ inch closed cell flexible foam, offering a snug fit that remains in place with minimal caulking required. For those seeking an extra layer of protection, Log Gap Caps can be sealed using our Energy Seal Caulk, effectively putting a halt to any potential water or air infiltration.

Say goodbye to energy leaks and hello to improved energy efficiency with Log Gap Caps. Upgrade your log home’s insulation and enjoy the benefits of reduced air infiltration and enhanced comfort.
