Customer Testimonials

Window Insulation Film NZ | Better Windows

“After the film was installed we have really noticed a difference. We have a central heating system and we don’t need to use it nearly as much. More importantly it’s just so much more comfortable at night.” Ron Goodey, Remuera.

“Since the installation our home is certainly a lot warmer and easier to heat. I’m happy with what they’ve done and their follow up service was excellent as well. Chris took time out to come over and help us by explaining everything clearly. He spent quite a bit of time with us to make sure we were happy at every stage and the installation guys were great.” Lindsay Hawcridge, Milford.

“Since the installation we’ve noticed that it feels a lot warmer and dryer, and that we don’t use the heater as much. People who walk in definitely notice a difference too, as it makes the house stay at a constant temperature.” Leslie Mills, Albany.
