how Iso-Mount Type1 acoustic hangers work

Sound passes through ceilings and floors as vibrations and sound pressure waves generated by footsteps, music or voices in an upper flat. These penetrate and travel through floorboards, joists and ceilings in the form of vibration and noise. By creating an isolated, floating ceiling using our Iso-Mount acoustic hangers you will stop the vibration that causes the transfer of unwanted noise from floor to floor.

Iso-Mount acoustic hangers are designed to achieve outstanding acoustic performance with fast and easy installation. The Iso-Mount is a proven, easy to use and affordable soundproof ceiling solution that brings serenity to any space, from houses and flats to offices, shops and restaurants.

“I did not fully appreciate at the time, but the use of Iso-Mount with industry standard metal channel was a huge bonus and cost saver. Also, we did not appreciate how much time and money we saved using the adjustable Iso-Mounts to level the uneven joists. Now installed the ceiling is superb and flat as a pancake. In terms of acoustic isolation the system is superb and overall I couldn’t be more pleased with the end result. The Iso-Mount system is a brilliant way to isolate noise between floors. I recommend it very highly.”

Richard Bowler – Oscar Iso-Mount Type 1 Soundproofing Basement Flat

“Once again thank you for your prompt response with processing our order for the additional Iso-Mounts. The owners took us by surprise when they asked for the additional area to be done, but they have been so impressed with the results of all the acoustic ceilings that they felt they just had to have it done.”

Derrick Murphy, D&M Murphy Plastering Contractors – Oscar Iso-Mount Type 1 Soundproof Ceiling

“The whole transaction has been simple and easy. I fitted the ceiling this weekend and it’s made an instant difference. So much so, that I had to ask the owner of the flat above if he had been using the room above.

I will recommend the product to my friends and will use it on other ceilings in my flat. Keep up the good work.”
