A superb, easy to fit, Direct To Joist System, engineered as a Part E compliant acoustic joist treatment, to save the developer time and money. It can be used in both new build and refurbishment projects for timber and masonry builds.
This product, used upside down, can also provide the resilient layer required for customers to make up their own resilient battens.
If the product is used in this manner, on a concrete floor, impact improvements in the order of: :
Delta L w22dB with a standard batten
Delta L w24dB with a deep batten can be expected.
Robust Details only require an improvement of Delta L w17dB
If the product is used in this manner, on a timber floor, improvements in the order of:
Delta R w+C; tr14dB and
Delta L w20dB can be expected.
Robust Details only require an improvement of:
Delta R w+C; tr13dB and
Delta L w15dB
Care should be taken to comply with all relevant Safety and Building Regulations.
The Joist Cap can be fitted from either above or below the joists and even before the joists are fitted.
The jaws of the caps are slightly tapered in to ensure a tight friction fit. Simply open the jaws and sit the cap over the joist ensuring the base is located tightly with the joist surface.
In all applications, our perimeter isolation strip must be used so the floating floor is fully isolated for the structural floor and walls.
