SPM

SPM high-density acoustic screens are used to provide acoustic insulation between two spaces.

Manufactured in rolls with 1 meter wide, they present 4 different levels of effectiveness depending on the surface mass of the product.

All SPM acoustic screens are manufactured with a modified bitumen base and are then coated on both sides with a polyethylene film.

The application of the GUMIES membrane is carried out by projection in order to achieve the desired density.
