Sound absorption is defined, as the incident sound that strikes a material that is not reflected back. An open window is an excellent absorber since the sounds passing through the open window are not reflected back. Conversely it makes a poor sound barrier. Painted concrete block is a good sound barrier but will reflect about 97% of the incident sound striking it. When a sound wave hits an acoustical material the sound wave causes the fibers or particles of the absorbing material to vibrate. This vibration causes tiny amounts of heat due to the friction and thus sound absorption is accomplished by way of energy to heat conversion. The more fibrous a material is the better the absorption; conversely denser materials are less absorptive.

• Position the FibreLine panels on the wall and mark the corners of the panel with pencil or chalk.
• Measure the position of the fixings on the reverse of the panels and mark the wall to correspond with the positioning of the clips.
• Fix the 'Z' clips to the wall in the appropriate position using 2 pan head screws.
• Carefully align the panels on the wall, using the pencil marks as guides and lift the panel over the wall fixing and then drop into place.
• If there is a requirement to trim the panels to size on site, carefully peel back the facing fabric from the base board.
• Cut the baseboard to size using a long bladed knife and straight edge, taking care not to damage the fabric.
• Spray contact adhesive onto the front and edge of the baseboard and smooth the fabric back over the fibre.
• DO NOT overspray with adhesive as excess adhesive could 'bleed' through the fabric.
• Trim off any excess fabric on the reverse of the panel.

FibreLine Wall Liner Panels

• Cut the top, bottom and end channels, and the T sections to the required lengths.
• Position and fix the deep U channel horizontally along the top of the wall with appropriate mechanical fixings.
• Position and fix the shallow U channel horizontally along the bottom of the wall with the appropriate mechanical fixings.
• Ensure the distance between the top and bottom channels is 20mm greater than the size of the panel being installed.
• Guide the top edge of the FibreLine Liner panel into the top channel, push it against the wall and slowly slide the panel into the base channel.
• Fit the intermediate 'T' section tightly against the FibreLine Liner Panel. Position the second panel as detailed above and slide it into to intermediate T section. This will conceal the joint between the two FibreLine panels.
• Repeat until the wall area being treated is fully covered. If there is a requirement to trim the last FibreLine Liner Panel to width, fit a shallow 'U'channel vertically along the edge before positioning the last 'T' section.
• Cut the Liner panel to size and slide into the end section. Fix the remaining 'T' section to cover the last joint.
• If any of the Liner panels need fitting around pattresses for light switches, power sockets etc.
• Trim the fibre of the baseboard to size and peel away from the fabric. Position the panels and staple the excess fabric to the pattress.
• Cut a small hole in the fabric to bring any cables through and fix the cover plates over the fabric to provide a neat finish. If the adjourning wall is to be covered, fix an internal corner trim and continue along the adjourning wall following the procedure detailed above.
• For any external corners or directional angle changes fix the appropriate trim sections.
• To cover walls in excess of 2700mm high, install additional panels above the first row by fixing a shallow U channel on top of the original top channel and install as detailed above until the required height is achieved.
