Is it worth the extra money to buy semi-rigid ducting with "Anti-Microbial and Anti-Static additives"? In my case, for a 100m2 cottage with 3 people occupancy. I need to choose between the Ubbink ducting with or without: AE48C Semi-Rigid Duct Anti-Microbial & Anti-Static 50m AE48C Semi-Rigid Duct 50m Thanks, Phil

We are having MVHR installed as part of a new selfbuild project. The designer is proposing Zehnder Comfoair Q600 MVHR as per attached. The Zehnder Comfoair Q600 will be installed within the house as shown on the drawings We are having a cold roof with insulations at ceiling with 100mm across then 400mm over. Our questions are around air tightness and also not compromise on insulation. Do we need to run the ducts o the ceiling then run the 500mm insulation on top of the ducting? Any advise would be appreciated. Many thanks

Hi, I have just powered up my newly installed MVHR system, a Vent Axia Sentinel Kinetic, 2 x 6 way manifolds and 50 metres of 90 mm semi rigid plastic ducting. It's a retrofit into the existing loft space. It seems to be working fine apart from the noise. Standing under the vents I can hear a gentle 'woosh' of the air coming out of the vents, but from even further away, I can hear what I'd call maybe a 'droning' noise, it's like there is an echoing in the ducting. Not sure how to describe it better. It's not massively loud, but loud enough to raise complaints from the family. As it's a cold loft, the Sentinel Kinetic has had a 25mm EPS foam box built around it, so it's sitting on a platform, with an EPS base. The same as the metal manifolds, these have 25mm EPS outer boxes too. The ducts are strapped to the top of the trusses. The whole lot has been covered with 400mm of new rockwall insulation. Any insight into where the noise is coming from and how to fix it are greatly appreciated. -
Hard hat on. It is possible to run MVHR ducting through a passive slab? I am starting to think about ducting runs from my bungalow with vaulted ceilings. As a bungalow, there are no joists to take the runs. Passive slab not poured for another few months at least.
