The Isocheck PHONEWELL system is designed to reduce excessive noise through floors, ceilings and walls.
Isocheck PHONEWELL is a cross fluted engineered card and hardboard carcass with a finely compacted loose sand mixture inside; it exhibits high mass with unique self decoupling properties.
The benefits of Isocheck PHONEWELL:
• Simple fitting, easy butt joints, no taping joints, no flanking
strips and can be cut with a knife or jigsaw
• Self load supporting for easy wall fixing.
• Minimal 15mm thickness.
Applications
To be used directly on existing timber or concrete floors, on resilient bars as part of a ceiling upgrade, to solid walls (with or without resilient bars and as part of a stud wall.
Performance (on the constructions illustrated)
The sections shown here are typical example construction details. In some cases Isocheck phonewell will offer an airborne improvement of around 3dB where it is installed directly against the masonry wall.
Whereas other examples where the system is decoupled could reflect as much as 12dB (with a good standard of workmanship). A good indication of the likely performance can be provided for a given construction on request with supporting test data where relevant. |
