Draftstoppa

$45.00

The DraftStoppa is a simple and clever Australian invention to help reduce your energy costs. It prevents hot or cold air from entering or escaping your home via your exhaust fan. The DraftStoppa is simple to install, requires little maintenance and can be fitted over most standard exhaust fans. Suitable for new builds and retro-fitting to established homes. The DraftStoppa is an inexpensive solution to help keep you warm in Winter and cool in Summer (see study results below).

A mounting plate is available for smaller fans.

Dimensions: Diameter 33cm x 16cm H

Materials: Made entirely from recyclable, fire retardant materials.


The Draftstoppa:

  • Prevents hot or cold air entering from the roof cavity.
  • Prevents polluted air or cooking smells from entering into other parts of the home or workplace.
  • Exceeds the Sustainable Energy Authority Victoria ‘First Rate’ energy rating performance level requirements for a totally self sealing exhaust fan.
  • Is economically priced and adapts to most major ceiling exhaust fans.
  • Fits most standard and 3 in 1 type ceiling exhaust fans.
  • Is simple to install and opens and closes effortlessly without loading-up your ceiling exhaust fan motor.
  • Is fully recyclable.

  • Further information:

    Test results concluded in Winter, with an outside temperature of 1ºC and an average internal room (10m x 4m x 2.7m—volume 108m³) and an internal ambient  temperature of 15.5ºC, the cold air inflow from the roof cavity through an unsealed fan into the room was measured at 13 litres / second.

    This means that for every hour 46.8m³ of cold air would have entered the room and the total volume of warm air would be replaced every 2 hours and 20 minutes at a huge reheating cost.
