Type C Hanger Soundproofing - How it works

When it comes to soundprofing a ceiling it is essential you consider the two things that need resolving. That is impact and airborne sound.

For those who are a little more budget conscious the Ceiling hangers are a good choice where you are able to lose 85mm-91mm ( or about 3 inches) of ceiling height. It is not an intrusive intrusive method of sound insulating your ceiling, as it is relatively mess free. This is because you tend to retain your existing ceiling. This is particularly the case where you have existing lath and plaster ceilings and don't want the mess of removing the old ceiling.

The Type C Hanger is part of a Regulation E systems for flat conversions the full soution can be found at be found at www.uksoundproofing.co.uk

The normal method of installation is to attach the hangers through the existing ceiling. These hangers house 50mm wooden battens that then act as the support onto which new plasterboard is suspended.

We also describe a method below which employs Isosonic Brackets which can be used with metal sections . The acoustic performance of both systems is identical.
For customers looking to insulate noisy pipes please see our acoustic pipe wrap.

Sound proofing basics

When soundproofing a ceiling it is necessary to improve three basic components.

1) The mass of the ceiling- This is normally achieved by adding two layers of acoustic plasterboard and high density wool. The SBx upgrade further enhances this by the addtion of even more reilient mass.

2) The Resilience of the ceiling- This is the springiness of the ceiling. Without this, the addition of the mass will have very little impact. The acoustic hangers are a very cost effective method of improving resilience.

3) The sound "absorbency" of the ceiling. By adding different components the sound gets trapped more easily within the ceiling; here we prescribe the easfit slab.

 

SBX Upgrades

For those customers looking for the maximum possible performance from an acoustic ceiling we also offer the possibility of an SBX board upgrade. This is a fine silica filled board the has excellent soundproofing properties far in excess of regular plasterboards. For an overview as to what the SBX board is please see here.

In general we believe that the SBX board will improve performance by around 8-10 db over and above the stated figures in the comparison table. There is also an improvement in impact sound performance as well.

The method for installation of this ceiling soundproofing solution straightforward.

  1. The joist lines of the existing ceiling is located, either via a joist finder sold at B&Q etc) or by carving into the ceiling.
  2. Along the joist line starting from one end you affix an acoustic hanger. Hangers are screwed into the joists at max 800mm centres across the length of the joist.
  3. Wooden battens ( kiln dried) are threaded through the joist hangers
  4. A Flexi edged mineral wool layer is affixed between the battens.
  5. A Double plasterboard layer is affixed to the battens and the perimeters sealed.
  6. Any spotlights placed in this ceiling will require acoustic hoods.

* Please note we do not supply the wooden battens needed for this solution . You will need 50mm by 50mm "kiln dried"

The action of the SBx board materially improves the performance of all solutions with particular emphasis on airborne sound. Improving it by around 8db over and above the stated performance.
*Please note figures stated for total system are based on a a timber joist ceiling floor construction with 200mm joist. The figures are Lab figures and are Ctr corrected. So are not comparable to regulation E Systems. The improvement figures state improvement over a regular timber floor and plasterboard ceiling.
Understanding Performance

The total performance which is normally quoted on most sites refers to the performance of an average ceiling with soundproofing materials added.

We also give an indication of performance uplift. Remember that every 10dB of performance uplift corresponds to roughly a 50% improvement in the performance of the wall. So 20dB would indicate a 75% Improvement over and above the original ceiling.

Sound Stop refers to Db improvement when we compare any of our systems. This we hope is an informative way of telling the customer what kind of improvement they will get when they add a soundproofing system. Many competitor sites offer products that will boast much higher numbers. Be aware these are often referring to a complete system which include the original ceiling or floor. This often leads to confusion when trying to compare systems. We are an independent site and as such will try to sell only the most effective solutions available in the market today.

 

 

 

 

 

 

If you prefer working with Metal then The Isosonic type C bracket has an alternative . The Isosonic Bracket.

ISOSONIC BRACKETS

Like resilient bars the ceiling brackets acts as a de-coupler by means of an acoustic grommet within the hanger that prevents sound transfer from one surface to another. The isosonic bracket outperforms resilient bars by around 3-4 db Isosonic ceiling brackets are best used when keeping the existing ceiling in place. The is recommended where lathe and plaster ceilings are present. The benefits are two fold as the lathe and plaster offers good airborne soundproofing qualities and they are very messy to pull down.

Isosonic ceiling brackets can be used for up-rating an existing ceiling. Performance wise the product has superior impact and airborne sound qualities when compared to resilient bars. The Metal section that is used for this product is the GL1 section which you can buy from us if you wish. Isosonic ceiling bracketsIsosonic ceiling brackets perfromance

Lath and platter ceilings tend to be good soundproofer's from the airborne perspective and similar to a double layer of plasterboard. Hence keeping them will not only reduce the mess but also mean a better final level of soundproofing. Remember that lath and plaster ceilings can be more unstable than plasterboard ceilings, (especially if water damaged) and this might affect your decision on ceiling retention.

 
Important note on recessed lights

If you are adding recessed spotlights in this ceiling you will need to add an acoustic fire retardant light hood to each light, otherwise your soundproofing efforts will be severely compromised due to the hole you have created. These can be purchased from our on-line store. Spotlight hoods
