Inside Story

It took many years of development and time for creators Ron and Sonny to perfect the Kozy Kollar and EV-4 before feeling confident in these alternative flashing and exhaust hood solutions! Here's a little more about how this product can work so well:

Roof Collar: Molded with our own EPDM compound and completely encasing the Main Frame.

Main Frame: A .125” steel frame with 7 case hardened pem nuts pressed in place.

Sub Frame: 1 galvanized steel plate.

Form-A-Gasket: 1.5oz tube of Permatex #2 Nonhardening Gasket Sealant.

Hardware: 6.5” X 2.5” rods will allow for varying roof thickness with easy to handle rod couplings.

The Main Frame: A rectangular steel frame molding into the roof kollar and serves as a flange to compress the three gasket systems of Kozy Kollar products.

Form-A-Gasket: A non-hardening, pliable sealant that is applied in the caulking channel of the Main Frame. The material is forced by pressure into any voids not sealed by the Main Seal.

The Diverting Seal is located along three of the outside perimeters of the Kollar leaving the bottom open for drainage.
Once installed, the Diverting Seal forms a snug fitting gasket designed to divert water around the Kollar.

The result? A quick and easy installation that pays for itself! You no longer have to risk your safety and climb on a roof to install these products. They can be installed at any time, by any person! All you need is our simple instructions, and you're ready to go.
