When you heat an uninsulated home, heat escapes, particularly through the ceiling. You have to keep the heater on to maintain a comfortable temperature while the heat and the cost, goes through the roof.

 

Pink® Batts® insulation saves on energy

Installing the correct level of Pink® Batts® insulation in your home will help you save on your power bills and over time will 'pay' for itself. 

According to BRANZ research, the cost of installing ceiling insulation in an otherwise uninsulated house in Wellington would be paid back by the savings in heating costs in 4 years. After 20 years this homeowner would enjoy a net saving of over $3,000(1a). 

 

Increase your insulation and decrease your energy spend

It takes a 1% (1b) increase in the cost of building a new home(2) to increase your thermal insulation from the New Zealand Building Code (NZBC) minimums to the highest levels of Pink® Batts® Ultra®. The higher R-values of Pink® Batts® Ultra® over the NZBC minimums decreases the energy used in heating and cooling by up to an extra 30% (3).
