Acoustic Joist Caps – Isolation Caps for Creating Floating Floors

Description

Acoustic Joist Caps are a superb, easy to fit, Direct to Joist Acoustic flooring 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.

Proven to be the most effective means of achieving superior sound attenuation, the mass of the structure is placed above the resilient layer. The product is then simply placed over the joists before the mass of the floor is added. The cap is suitable for both rough-cut and planed timber joists.

General Physical Data:

• Length : 2m
• Width : 50mm
• Thickness : 12mm
• Density : 30kg/m3

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
