Who benefits from our training events?

Insulation Contractors

Attending an HPIP workshop and earning High Performance Certification differentiates you from the competition. Our program is unique and diverse to other industry related trainings with two of the largest industry competitors working side-by-side to educate and train installers. The dedicated instructors we are lucky to work with are the best of the best in the industry. Learn about a new system, product, or technique while networking with industry leaders.

Industry Professionals

The installers aren’t the only attendees that will benefit from our training experience - raters, builders, architects, and code officials can equally benefit. See first hand what contractors in your area are learning, and even give feedback on what you’d like to see in the field. HPIP offers 1-2 educational sessions to industry professionals in the region we are working in to educate attendees from a new angle of the energy profession.

Manufacturers, Distributors, & Industry Partners

Demonstrate the systems and products your company has to offer to new and interested contractors. Meet new customers and network with other industry professionals. *HPIP’s purpose is strictly educational, and the purpose of our events is not to push products on our customers, but to inform them on some of the best industry products to achieve a Grade I insulation installation as defined by RESNET standards.*


HPIP holds its HP Certified Contractors to Grade I standards. When installers attend our trainings and learn from the best they are more likely to achieve Grade I on their installs. The better the install, the more efficient the home, the happier the customer. A happy homeowner is a win for everyone!
