Jumpax CP Acoustic Underlayment
Impacta Jumpax CP Dry Screed Floor Underlayment System



Note: Jumpax® CP is replacing Cera Silence underlay


Jumpax® CP is a dry levelling cement based screed underlayment system developed to be installed over lightweight wood frame construction in place of gypsum topping. Jumpax® CP consists of a top & bottom cement bonded panels that weighs 4 ¼ lb per sq ft and will increase jumpaxcpthe STC rating. Jumpax® CP is an excellent alternative to gypsum based topping which can take up to 28 days to dry before flooring can be installed. Jumpax® CP allows for fast track installation in which most floors can be installed the same day. Jumpax® CP can be used in combination with many floor coverings, including hardwoods, ceramic tiles; sheet vinyl, luxury vinyl tiles, cork, linoleum and rubber (resilient vinyl floors will require floor patch over seams).

Jumpax® CP can also be installed on top of an acoustic underlayment to increase the IIC rating. Because Jumpax® CP is a floated system it can be installed over Paladin, Redupax or jumpax cpProBase underlayments which allows you adjust the threshold height based upon the underlayment used as well as adjust for acoustics. Jumpax® CP was recently tested over a 6” slab with a 12 mm wood fibre underlay an achieved a 22 dB noise reduction ∆Lw 22. Jumpax® CP is constructed of non-flammable Class A fire rated materials.
