High Performance delivered a quality, quick, professional product and service. They were quick on reviewing the project on site, sending in an estimate and once accepted doing the work in a very quick time frame. Very knowledgeable, not pushy, explained things very clearly from a customer solution perspective non sales perspective. Added in thermal barrier paint on top of spray foam looks great warmed up and sound barrier-ed the garage excellently. Allowed flexibility in payment method, was very much appreciated. HP was reasonable and when compared to installing hard foam insulation DIY, they were marginally more expensive. I highly recommend the company and approach. The solution for my garage was cathedral ceiling based, meaning insulated on the underside of the roof without the need to close in our lose your rafter storage space.
