This Fresh-r can be partially built into the wall. Ideal for a shallow cavity or when a secondary insulation wall is used.
A mold-free, healthy, and comfortable home. Plenty of ventilation volume and heat recovery with a modest appearance; protrudes only 6 cm from the wall.
The house is sealed airtight and the thin wall gets an extra layer with insulation. And in that wall, you install the Fresh-r, which provides fresh air without energy loss. If desired, you can also extract air from another room via a duct.
