1> 100% polyester fiber made through high-tech hot press and according to the cocoon shape.

2> Achieve diverse density to ensure the ventilation, becoming the outstanding materials for the sound

     absorption and thermal insulation.

3> Within the frequency of 125-4000Hz, the absorption coefficiency can reach more than 0.9.

4> Material has a good decoration, thermal insulation, fire retardant, eco-friendly, light weight and impact

     resistance etc. various advantages.

                                                                                                                                                Send inquiry soon>>

Acoustic absorption is usually defined in terms of an absorption coefficient(usually denoted by the Greek letter alpha, α),

defined as the ratio of absorbed to incident sound energy from a single interaction between a sound wave and a certain material.

Absorption coefficients range from 0 to 1 and vary with frequency,

α=0 means that the material absorbs no sound and reflects all sound energy incident on it.

α=1 means that the material absorbs all sound energy incident on it and reflects none.

Absorption coefficients of 0 and 1 are ideal values that do not exist in reality because all materials reflect and absorb some sound.

In general, materials having absorption coefficients less than 0.15 are considered to be reflective and those having absorption coefficients greater than 0.4 are considered to be absorptive.

As you can see our Testing report show that our products have a very good performance in a large range of application.

1> Typesetting Typeset and adjust SWAN-LAKE polyester acoustic board to certain shape on the performed section.

2> Chamfering Either mechanical or hand-cut; recommend rigid steel ruler if you decide to cut by hand and

      you’d better use imported art blade.

3> Cutting We have special chamfering tool to chamfer various bevel edge so as to meet different aesthetic

      point of view.

4> Installation We mainly use glue such as spray glue, hot melt adhesive, white glue, glass glue, etc.

     (according to different surface) to stick acoustic panels onto the wall. For flat cement wall, you may install

     the boards directly with white glue and gun nail, which is glue-saving and time-saving.

     Pasting sing-side glue on the based surface is strongly suggested as well as layering process.
