What our customers are saying

High R values, at a reasonable price
"For our new home build, we wanted the highest level of insulation to compliment our "no bills" concept. The traditional glass wool products offered in New Zealand just don't do the job, so it was great to find the team at The Alternative Energy Company, who offered proper insulation with high R values, at a reasonable price. We have used Eurothane insulation throughout the build, fitting it under the floor slab, in the walls and ceilings. Already we are feeling the benefit: Cool in summer and really toasty in winter. We don't use any heating in our new home - we don't need any, as the sun provides all the heat we need and the insulation retains it; the log burner is pretty much redundant! The product has performed really well and it was a pleasure dealing with this company."

"I’ve purchased PIR from multiple suppliers in New Zealand and so far, this is the best one. It does not crumble too much, which makes it quite easy to cut with a cutter. It's a bit more expensive than the competitors, but overall it's a better deal and I’ll be a returning customer."
