Roof Rigid Fosm Insulation Stc Rating

The thicker the better for both thermal and noise insulation.

Roof rigid fosm insulation stc rating.

This can range from 0 to 100. This foam board insulation is the rigid pink or blue panels that can be found at home centers in many different thicknesses. It is available in all different size configurations to accommodate lots of different applications. The higher the stc rating the more effective the barrier is at reducing the transmission of sound.

The bottom layer of a single ply membrane roofing system is the roof deck or substrate. Sound transmission class stc is an integer rating of how well a building partition attenuates airborne sound in the usa it is widely used to rate interior partitions ceilings and floors doors windows and exterior wall configurations see astm international classification e413 and e90. Why open cell oc spray foam is best for sound attenuation. With a density of 4 lb ft it can be used in walls ceilings or floors.

For example a wall with an stc rating of 68 means that noise levels on one side of the wall are 68 decibels higher than on the other side of the wall. Rigid foam insulation installation prepare roof deck. R tech is available with factory adhered metallic reflective facers white facers or a combination of the two. Polyiso is an easy cost effective sustainable and energy efficient construction material.

Choose rigid insulation wisely and consider the effect its characteristics will have on the performance of the your project overall product cost and the best way to get the bang for your buck. Acoustimac acoustic insulation eco cellulose comes in soft yet rigid 48 x24 x2 sheets. It has an stc rating between 44 and 68 depending on thickness and density. It is denser than eps and provides more r value with a rating of 5 per inch of thickness.

Rigid foam insulation packs a lot of r value into a thin package but not all rigid foam performs the same. Provide separation of foam insulation from interior of the building with a 15 minute spaces such as interior corridors and service areas provide sound transmission class stc ratings of not be less than 50 45 if field tested when tested in. The roof deck can be plywood metal concrete or wood planks. It ties with rock wool batts for an stc of 50 in a laboratory test environment.

However in real construction a batt would be cut to fit around utilities and boxes leaving sound transfer cracks. This foam board insulation is available with straight or tongue and groove edges to help limit air movement. First spray foam has the best stc rating of all the options. The first step with roof installation is to prepare the roof deck by getting rid of all dirt dust and contaminants.
