I have an older two-storey house and want to install balanced ventilation. Is this practically possible?

Yes, it is practically possible to install balanced ventilation in an older two-storey house, but the level of complexity will vary. On floors with an attic above, it is usually relatively straightforward to route ventilation ducts. On floors without an attic above, installation is more challenging, and ducts must typically be routed within the floor structure or boxed in along walls or ceilings. The solution must be adapted to the building’s construction and floor plan and should be carefully considered during the planning stage to ensure a good and functional result.
