Noise Transmission Between Floors
A critical area to consider when insulating a home or building is insulating between floors for both thermal heat loss from downstairs in winter but primarily from noise between floors, both upward and downward.
Each of the products below have their own merits and it is more likely that a combination of multiple products may be used. Definitely consider some of the points listed below when adopting an insulation solution for this application.
If you need further technical advice, consult with the Solartex team.
It is also necessary to consider the following when insulating between floors:
Autex Greenstuf polyester batts are primarily used as a void filler between timber or steel joist applications, due to the large depths and spaces created between floors.
Autex Quietstuf polyester batts are an acoustically denser product and is also available in 200mm thickness.
Autex Acoustic Absorbtion blanket
(AAB) is designed in a variety of thickness and densities to suit most applications.
Rockwool is a very dense mineral fibre material used for adding mass to a structure and sound deadening. ideal for interal walls and between floors. Care should be taken with installation due to the irritant nature of the product but once locked between floors or internal walls should not pose a health risk. Note that it is generally available in thinner batts and is not suitable for filling deep voids between floors.
flexible acoustic membrane can be added during the floor construction stage, above or below, to provide a barrier to both impact and airborne noise transfer.
Acoustic Pipe Lagging is a flexibile loaded aluminium foil laminated 15mm foam blanket that is measured and cut on site to wrap around PVC waste pipes between floors. DO NOT NEGLECT WRAPPING YOUR WATER AND WASTE PIPES between floors.
