How it works?

Ventbox utilises airtightness, EWI and heat recovery technology to provide you with an efficient and effective solution to low energy living. Through the implementation of PassiveHaus principles, high quality engineering and experienced installers/trades people, Bow Tie Construction’s Ventbox system is able achieve performance above and beyond retrofit project standards.

By controlling the flow of air that is allowed to enter and exit your home we are able utilise any heat generated within your home rather than waste it. Our heat recovery system extract any warm stale air from your home and use this heat to warm incoming clean filtered air.

The Ventbox will also control unwanted moisture within your home and under suspended timber flooring. Not only will we extract moisture from sources within your home such as kitchens and bathrooms, Ventbox sustains a flow of air under your suspended timber floor. This addition negates any need for underfloor insulation and will prevent the build up of any mould growth within the home while maintaining a controlled circulation of clean air.
