AIRFLOW is a ridge roll product that has air vents to release hot air trapped in the ceiling, helping cool homes. It won third prize in a 1996 invention contest. Hot air rises, so the vents at the top of the roof allow hot air to escape, lowering interior temperatures without active systems like air conditioning.

2. Much Cheaper than the Turbine Type air vent. It also doesn’t need electricity. There’s no moving parts that need to be replaced. And no need for maintenance. More practical , than insulators that still retains hot air and has to cover the entire roof and besides, it is ideal only for newly constructed houses. Easy to install and very effective . It can be installed like any ordinary ridge roll and yet it is more durable and has a better static effect.
