Testimonials:

"I've been using Enercept panels for the roof and gables of the log homes I build for many years. The people at Enercept are friendly, knowledgeable and always helpful. The panels are amazingly easy and fast to assemble because they come completely fabricated. The window openings and complex roof angle cuts are done at the factory - we don't have to cut any panels on site, they just slip together." "I would rate the insulation qualities of our Enercept home 100% better than any other house we have lived in. Even the floors in the basement, which are constructed of Enercept panels, are warm to the touch, even with the coldest temperatures outside. One of the major factors in deciding to build an Enercept home was the energy efficiency. After living in our home over the winter, I can say with certainty that the decision was a very wise one. I would recommend building an Enercept home to anyone that asks me." L Andera​

"Delivery was coordinated in a very thoughtful way to reduce costs and worked out beyond what one would normally expect. The panels were constructed very well and were precise. Thanks for the opportunity of dealing with a great company!"

🌟 EMPLOYEE SPOTLIGHT: JASON 🌟

Meet Jason, our Drafting STP Design Specialist! Jason says his favorite part about working at Enercept is being able to draw and see those drawings come to life through the partnership we have with the Production Team.

When it comes to being part of the team, Jason appreciates the inclusive nature and how ideas are shared between Production and Drafting to prove, improve, and improvise when necessary. He says that sometimes once a design is “finished,” it can feel like it’s locked in and must be built that way—even if it doesn’t work. At Enercept, however, there’s more flexibility. If there’s an issue, someone on Production can ask him about it, and sometimes it just needs to be explained, while other times the design may need to be changed. He enjoys that flexibility and teamwork.

His advice to someone thinking about joining the team? Keep an open mind and ask questions! If you don’t understand something, ask who can explain it or ask, “How do I do that?” Jason says there are some incredibly knowledgeable and experienced people on the Production Team, so lean on those resources, learn, and improve.

As for a hidden talent, Jason says he’s a pretty good cook! He frequently improvises new dishes—some are delicious, some are just okay, and some don’t turn out exactly as intended, but they’re still good. Rarely does he have something that turns out completely bad! 😂
