Seal Design’s Foam: A Fiberglass Alternative
A foam insulation product used increasingly in home building is being introduced to the RV industry by Seal Design as a superior alternative for insulating and sealing RVs.
Seal Design is an affiliate of Dicor Corp. and provides a variety of sealant products to RV manufacturers. Its new Touch-N-Seal foam polyurethane insulation results from the chemical reaction of two liquid components that combine in a spray gun to produce sprayed-in foam that quickly expands to fill even the smallest crevices, before hardening into solid, lightweight-structured insulation. It is a practical alternative to the fiberglass used in most towable RVs today, according to a news release.
Small gaps typically left by fiberglass insulation as it is rolled over studs, or is tucked around cutouts for windows, doors and hatches, are filled by the solidified foam. Along with its better seal, Touch-N-Seal has an R-value of 7.2 per inch compared to a typical R-value of 3.2 per inch for fiberglass insulation used in RVs. Additionally; Touch-N-Seal provides better insulation for sound.
Another benefit is the solid foam’s ability to limit water damage and mold growth from potential leaks because of the tight interior wall seal it achieves. “Unlike fiberglass batting, water cannot penetrate the closed-cell foam, and the foam will not hold water inside the walls like fiberglass, reducing the chance of serious damage from water intrusion,” said Greg Kelly, general manager of Seal Design.
The polyurethane foam also strengthens the walls as it solidifies, while weighing less than fiberglass. “So you’re strengthening the wall while reducing weight at the same time,” said Kelly. “That’s what manufacturers are looking for these days.”
“We know our customers and the industry as a whole need better insulation solutions, so Seal Design looked at some of the best performing sealing technologies in other industries and this is one of several new products we determined could very practicably be used in the manufacture of RVs,” said Kelly.
For example, using a spray gun, a single worker could more quickly insulate a wall than by cutting and gluing fiberglass batting between the studs. Seal Design provides delivery systems that include a new CPDS 1000 dispensing system. This system is portable and delivers a constant pressure using compressed air, enabling higher foam yields and fast installation. Installation is in compliance with Energy Star and AAMA standards.
“It also saves a ton of storage space for the manufacturer,” said Kelly. “Two-inch thick fiberglass takes up to 30 times the space that Touch-N-Seal materials would occupy.”
“By enhancing productivity, Touch-N-Seal would financially benefit the manufacturer before its units even leave the line,” said Kelly. “For dealers, the energy-saving enhancement, the sound muffling, and water-blocking properties — they all provide excellent benefits to talk about. This could help differentiate RVs in a category where buyers are looking for something new.”
The new foam insulation will be introduced at the National RV Trade Show Nov. 30 to Dec. 2 in Louisville, Ky. It will be part of the Seal Design display at the Dicor Corp. booth, No. 260, North Wing Lobby.
