Regupol 3912 Acoustic Underlayment for Refurbishment: is a tough, resilient acoustic underlay manufactured from PUR foam and is ideally suited to refurbishment and timber based constructions to comply with Part E, 2003. It can also be used for new build but you must ask first a technical advise from our team.
Regupol 3912 and WAKOL TS 102 (WAKOL TS 103)
Recently I was asked by a customer why I recommended Regupol 3912 instead of Wakol TS102. The second was presented by another company as being a better solution for that particular type of floor and sub-floor.
After doing some technical research I turned with the following comparison.
First of all is good to know that these products are designed to reduce the impact sound like the footfall, dropping objects etc. They are not meant to be used as a standalone soundproofing solution.
Also they are innovative products since gluing down the wooden floors is possible over them.
Main characteristics: 6mm thick, impact sound insulation 23dB without other materials like a multilayer wooden floor
made of PUR foam (polyurethane foam), Resistant to ageing and deformation, Suitable for use with under floor heating, Can be used over many types of plane and sound sub-floors.
Wakol TS 102 (Wakol TS 103)
Main characteristics: 2mm or 3mm thick, impact sound insulation 19 dB in combination with 10 mm multi-layer parquet
made of cork and PU foam granules, Can be used over many types of plane and sound sub-floors.
We can notice 2 very important differences: in thickness and in sound reduction capabilities.
Returning to our initial case the main requirement was to achieve the best possible impact sound reduction. Therefore my recommendation for Regupol 3912. By itself can reduce the impact sound with 23dB and when added the wooden floor this figure will increase in accordance to the board thickness and density. On the other hand Wakol TS in conjunction with a wooden floor of 10mm thickness will reduce the impact sound with 19dB. Since the materials used in manufacturing them are similar we can divide the dB with the mm and apply the rule of three to understand that we have the Regupol 3912 twice better than Wakol TS103 when it comes to impact sound reduction.
When comparing the thickness of both it is clear that Wakol TS 103 will not raise the floor level in a noticeable way and will still provide a minimum of impact sound reduction. This aspect might be critical if the height of wooden floor has to be matched with tiles height for example.
