"We had double glazing installed by Ecosee in our rental property at Arthur's Pass. This replaced old double glazing which had failed. We were very pleased with the clean lines of the new retro-fitted glazing and have noticed a good increase in the heat retention in the house. We experience some very rapid changes in the weather here from 5 degree frosts to plus 5 degree temperatures within a very short period of time and the new glazing has stood up very well to these rapid temperature changes"
