Traditional insulation materials do little to block radiating heat from water tanks. Low-E is different. Made of 99.4% pure aluminium, Low-E Insulation reflects 97% of radiant heat. Save as much as 20% with our quick and easy to install Water Tank Insulation. Low-E Insulation EZY Seal has a self-adhesive strip along one side of the roll to make joining rolls quick and simple. The self-adhesive EZY Seal edge can be used to overlap or seam join to another roll and ensures a strong bond. “We used Low-E Insulation to insulate outdoor water tanks. We used to lose a lot of water through evaporation in the summer months. It is made a huge difference. We have now insulated of hot water tanks indoors, and we have noticed our energy bills have gone down too. I’d definitely recommend Low-E Insulation.” – Helen B, Dublin, Ireland
