Roof ventilation reduces unwanted heat build up as it lets the hot air vent through the roof. We add a simple heat activated vent to our roof which works by opening up automatically when the temperature reaches 27 degrees C or 80F. It is a simple automated way to keep cool and save money.

Currently our house has no ventilation in the ceiling. The vaulted ceiling in the house means the hot air in the house rises up and gets trapped there. Keeping the heat inside and making the house uncomfortable

So we are going to install one of these, it’s a very clever heat activated vent designed to let the hot air out and invite the cooler air in.

I’m going to try demonstrate how it works with a heat gun. In hot weather when the temperature rises, the fluid in this part of the vent heats up and expands.

This opens the butterfly and lets the hot air out inviting cooler air into the house. And when the temperature drops the fluid contracts and the butterflies close. Lets go fit it and see how it works on the job.
