Ensure your subfloor is clean dry and most importantly level ready to receive the flooring. Install dB Matting 15 over your level subfloor. DB Matting is installed in a brick bond pattern, bond down to the subfloor using Mapei Elastorapid VS90 or F3 adhesive, apply the adhesive with a 3mm notched trowel and lay the dB Matting over the adhesive. Install the dB Matting tightly to the walls at the perimeter of each room. If there are any gaps around the wall infill with acoustic sealant.
Install the Unifloor Jumpax Heatpak over the dB Matting 15 (see full Jumpax instruction here). The 3mm baseboard is installed first 'tacky' side up, then the 4mm top board is cross-staggered over the baseboards, peeling away the film to lay on its self-adhesive back. Leave a 5mm expansion gap around the perimeter of the jumpax and infill with an acoustic sealant. The Jumpax creates a cross-braced level solid floor with minimal deflection to receive your LVT floor finish. It also provides an MDF surface for the LVT to be bonded to or laid on.

Important Information
Sound Insulation Store are specialists in acoustics and sound insulation. All guidance, system information and predicted performance figures are provided for general assistance only.
It is the customer’s responsibility to ensure that the existing structure is suitable and compatible with any proposed sound insulation system. Where required, customers must seek advice from a structural engineer, building control, or another appropriately qualified professional.
Customers must also confirm whether their project requires specific fire resistance, structural, or regulatory compliance measures. Any fire, structural, or regulatory approval must be obtained independently from a competent specialist.
Sound Insulation Store has worked with NCPL to produce Insul prediction graphs and holds site test data on our Part E systems. These figures are intended as guidance only.
Actual on-site performance will vary depending on the condition and construction of the existing building, flanking transmission routes,installation quality, and any unforeseen site variables.
No performance level can be guaranteed unless independently tested on site after installation.
