Isosorba acoustic ceiling insulation systems are designed to reduce noise transmission through ceiling construction in multiple dwellings. Not only do these systems reduce airborne sound but are also very effective in reducing impact noise too.
The ceiling insulation systems are simple but very effective. It can be installed easily with minimal disruption by the work being carried out below the ceiling to meet Approved Document E of the Building regulations.
Acoustic Performance
Isosorba 95 is used where an improvement is required to make the noise transmisssion more bearable.
Isosorba 150 is used where there is a need to meet Approved Document E of the Building Regulations.
Installation of Isosorba 95 – Improvement Standard
Store the Isosorba components in the rooms where they are going to be used for at least 24 hours before use at normal room working temperature. Screw fix the 50 x 50mm timber battens, using wood screws, through the plasterboard ceiling and into the floor joists and ensure a firm and strong fixing at not more than 400mm centres.
Fit Soundsorba 50mm thick acoustic insulation quilt between the timber battens. Using wood screws, screw the 15mm Soundsorba Resibars to the underside of the 50 x 50mm timber battens. The Resibars should be fitted perpendicular to the timber battens..
Install the first layer of 15mm thick Soundsorba acoustic plasterboard screwed to the Soundsorba Resibars with 42mm drywall screws. Seal all the board joints as well as the perimeter joints where the boards butt against the walls using Soundsorba acoustic sealant.
Install the second layer of 15mm thick Soundsorba acoustic plasterboard screwed through the first layer of acoustic plasterboard. Make sure you stagger the joints of the second layer of acoustic plasterboard.
Plaster finish to ensure sealing of all joints.
Installation of Isosorba 150 – Conversion Standard
Store the Isosorba components in the rooms where they are going to be used for at least 24 hours before use at normal room working temperature. Screw fix the 100 x 50mm timber mini joists to similar size wall plates, ensuring that these new joists framework does not physically touch the existing ceiling and leaving a minimum gap of around 10mm.
Fit Soundsorba 100mm thick acoustic insulation quilt between the mini timber joists. Using wood screws, screw the 15mm Soundsorba Resibars to the underside of the 100 x 50mm timber. The Resibars should be fitted perpendicular to the timber battens.
Install the first layer of 15mm thick Soundsorba acoustic plasterboard screwed to the Soundsorba Resibars with 42mm drywall screws. Special attention should be taken to ensure that the screws only locate onto the corrugated web of the face of the Resibars and do not make contact with the timber mini joists. Seal all the board joints as well as the perimeter joints where the boards butt against the walls using Soundsorba acoustic sealant.
Install the second layer of 15mm thick Soundsorba acoustic plasterboard screwed through the first layer of acoustic plasterboard. Make sure you stagger the joints of the second layer of acoustic plasterboard.
Plaster finish to ensure sealing of all joints.
