Acoustic decoupling of the subfloor or screed
Calpestop allows the screed to be completely decoupled from its substrate, all vertical building structures and penetrating pipework, resulting in a significant reduction of impact noise transmission.
Improves the acoustic performance of Laterlite screeds and screeds.
Calpestop is compatible with Laterlite lightweight and technical screeds.
Thickness ranges from 3 to 10 mm
Calpestop is available in different versions and thicknesses to meet different technical needs.

Please refer to the product data sheet and documentation for complete information about application.
The CalpeStop range consists of chemically cross-linked, closed-cell expanded polyethylene foam elastic matting – density approx. 30 kg/m³, thermal conductivity λ 0,0372 W/mK – available in different thicknesses and types, faced with different materials (aluminium, wadding, geotextile).
Supplied in rolls, perimeter flanking band is available separately as an accessory.
VERSIONS
Super: , faced on one side with a sheet of goffered aluminium that increases resistance to abrasion and vapour.
Available in thicknesses of 3, 5, and 10 mm.
Super 3 : Overall thickness: approx. 3 mm – Dynamic stiffness 40 MN/m3
Super 5 : Overall thickness: approx. 5 mm – Dynamic stiffness 31 MN/m3
Super 10 : Overall thickness: approx. 10 mm – Dynamic stiffness 25 MN/m3
Super TNT: the matting (thickness 5 mm) is faced on its lower side with a sheet of goffered aluminium foil and on its upper side with a special nonwoven fabric that increases its resistance to abrasion.
Available in thicknesses 5 mm.
Overall thickness: approx. 5 mm – Dynamic stiffness 35 MN/m3
TNT: the matting (thickness 5 mm) is faced on its lower side with special wadding (approx. thickness 3 mm) and on its upper side with a special nonwoven fabric that increases its resistance to abrasion. Overall thickness: approx. 8 mm.
Available in thicknesses 8 mm: polyethylene foam 5 mm + wadding 3 mm.
Overall thickness: approx. 8 mm – Dynamic stiffness 31 MN/m3
Flanking band: uncoated polyethylene foam insulating strip, adhesive on one side, intended to act as a buffer to reduce flanking noise transmission and to decouple the screeds from vertical building structures and penetrating pipework.
Thickness 3 mm.
