Iso-Mount soundproofing house case study

Soundproofing house with Iso-Mount: acoustic comfort at a sound price

Buy Iso-Mount

Richard Bowler wanted to tackle noise transference as part of his basement flat renovation in Autumn 2020.  He turned to Oscar Acoustics to solve the issue cost-effectively, choosing Iso-Mount Type1 soundproof ceiling acoustic hangers to dramatically reduce noise from the house above with minimum ceiling height loss.

Quality soundproofing is fundamental to the enjoyment of our homes. High levels of noise can affect our health as well as our sense of wellbeing.  So, when Richard planned a complete revamp of his basement flat, part of his nineteenth century, four storey Devon property, he was determined to factor in sound insulation, while also creating a beautiful interior finish.

Problem: Lack of sound insulation

“Dating from 1850, the basement flat was of very poor construction and in need of complete renovation,” clarifies Richard.  “In particular, with respect to the seven different ceilings of the flat and the ground floor of the house, there were undersized joists, making it uneven, bowed and springy.  The wooden floorboards in the house had large gaps between them, and the ceiling of the flat was constructed with thin plasterboard.  This meant no sound insulation at all - even a conversation could be fully overheard.”

Solution: Soundproofing house ceiling with minimum height loss

Richard wanted a fast, cost-effective, and easy to install solution to solve the noise problem.  He discovered Iso-Mount Type1, an isolating acoustic ceiling hanger which significantly reduces transmission of noise from the floor above but only loses 6mm of ceiling height.  Further with this choice, it’s possible to carry out all work from the room below.

"I selected Iso-Mount because it was simple and easy to install with extensive video instructions,” Richard says. “My builder, had never installed an acoustic ceiling, so it was important to find a solution he was confident with."

“I did not fully appreciate at the time, but the use of Iso-Mount with an industry standard metal channel was a huge bonus and cost saver.  We have saved a great deal of time and money using the adjustable Iso-Mounts to level the uneven joists.”


Process: Simple soundproofing house installation

Richard’s builder, Mark Lipton started the Iso-Mount Type1 installation in one of the smallest rooms of the flat. Within two days, he was confident using the height-adjustable acoustic hanger.

Marks says, “Initially I was unsure about the system as I had not used it before.  I started with the bedroom as it seemed the easiest to install.  Once that was done it was easy to fit the other ceilings.  The living room was the largest room and the most uneven in terms of joists.  The ceiling went up in no time.”

“One of the nice features of the system is that it is easy to create a false ceiling to run services.  It was also useful in complex areas where, for example, we had a concrete lintel to accommodate.  The fiddliest part of the whole install is fitting the rubber isolators to the mounts.  On the other hand, achieving perfectly level ceilings was very easy.”

“We used belt and braces which included the Iso-Mounts, the acoustic tape, the sealant, foam filler, acoustic insulation, and two layers of SoundBloc plasterboard,” says Richard.  “The SoundBloc was the most challenging install since it was much heavier than ordinary plasterboard and my builder had to work hard to install it. From my perspective it is only marginally more expensive and worth it for the extra isolation.”     

Result: A ‘superb’ soundproof ceiling system for soundproofing house

With installation completed in ten days, Richard was delighted with the ceiling. 

 “For acoustic isolation, the Iso-Mount system is superb. It even created a perfectly flat ceiling despite the uneven joists above.  Noise transfer between house and flat is far, far reduced.  When experiencing noise transfer now it is normally through an open door or window rather than transmitting through the floor/ceiling." “We had no woodworking or fillers to add or level off.  We simply used the adjustable Iso-Mount for reduced noise transfer. 

The Iso-Mount system is a brilliant way to isolate between floors and I couldn't be happier with the results.  The ceiling is superb and flat as a pancake despite the uneven joists above.  I highly recommend it."
