Flexible horizontal installation

Many modern homes have flat roofs or limited roof space that render ducted ventilation inappropriate for installation. With H-line's horizontal through-wall ventilation, roof space issues no longer stand between your space and natural, fresh home ventilation. Even typically musty smelling basement rooms can be freshened up with an H-line.

What people are saying

"My home has a skillion roof so with little roof space the traditional ventilation solutions are just not an option. So, I was thrilled to learn of the Unovent H-line and even happier once installed. I really like that I can adjust to my needs with the three cycle options. It looks great, very sleek, and minimal. Most importantly, it is in my lounge and now the air in that room is fresher and drier. I would thoroughly recommend.
