Energy Efficiency
With up to 40% of a home’s heating energy lost and up to 87% of its heat gained through windows*, improving their thermal performance reduces energy
costs and Australia’s greenhouse gas emissions. Careful window selection and placement is also rightly viewed as a means of reducing demand
for artificial light and climate control.
The lower the U-value, the better the window. Paarhammer U-values start from a very low 0.8 WERS (Window Energy Rating Scheme).

Windows and doors are rated as a whole, meaning glass and frame together. High performance glazing is not very effective if the window and door frames leak air and create
a draft. Proper installation is also an important consideration.
Paarhammer products feature up to 7 1/2 Energy Stars, meaning that you can save up to 85% of energy in addition to enjoying a very comfortable
indoor climate in your home or at your workplace.
