about no Draft
Draft - the enemy of achieving energy savings.
We have long understood that achieving excellent energy ratings goes well beyond double glazing. We know it's also in the framing and sealing.
That's why our windows and doors have achieved the highest ratings in Australia - over many years. It's just one of the reasons why our windows have become so popular for the most demanding projects.
The evidence shows that most of the warm or cool air is lost through windows and doors. While providing views, natural light and fresh air, they can also allow heat to enter and leave your home quickly. Many conventional sliding, bi-fold doors and windows suffer from air leakage. Paarhammer window and door systems have extremely low air infiltration and can save up to 84% of your energy costs, please see WERS Window Energy Rating Scheme.
Our frames and seals contribute beyond draft elimination
Extensive testing by independent Fire Testing Laboratory Exova Warringtonfire proved that, apart from fire resistant timber and specialty glass, our seals and hardware contributed greatly to our window achieving the first BAL-FZ (Flame Zone) approval in Australia.
