Counter Balance Window System from Evalock

counter balance window

Evalock's Double Hung Counter Balance Window System boasts Evalock's patented double roller component, specifically designed to meet the needs of the heavier weight loads that double glazing may sometimes require.

The ease of operation of these windows is similar to that of the box frame window. One sash counter balances the other so the hot air escapes over the top sash and the cool air enters under the bottom sash. Size and therefore weight, are not factors in double glazing.

Evalock's Counter Balance Windows have been tested and are suitable for:

  • N4 Housing Rating
  • 1500 Pascal Design Rating
  • 450 Pascal Water Penetration Rating
  • Air conditioned application

Evalock's double hung windows are manufactured to Australian Standards AS1288 and AS2047
