About Us - K4 Insulation Machines®
About Us

We're a small family business here in California that started off selling all types of products you can imagine. Our journey started in the insulation industry when my best friend of over 50 years who owned an insulation company asked me, "Do you sell insulation vacuum bags? The bags I use keep tearing." My response was, "No, but I'll see if I can help."

When I realized the quality that should be offered wasn't being provided, my family and I decided to create the perfect vacuum bags for my childhood friend. The news spread quickly among his peers. We were no longer his personal source for insulation removal bags but the #1 provider of incredibly durable and tear resistant vacuum bags to thousands of insulation professionals across the country.

We knew we could offer more, so we expanded our line of products to high quality and affordable insulation blowing machines, vacuum machines and equipment. We wanted to make a powerful impact on our customers and help them achieve the best results possible.

Our Mission

From day one, we made a promise to our customers: Provide you with carefully designed, affordable insulation machines and equipment that help you get your job done safely and efficiently.

Superior quality and outstanding service is the heart of K4.

Thank you for supporting our family and helping our business grow.
