The first foam layer may include a polyurethane-based matrix component, and a flame retardant filler component. The multilayer component may also have a HBF flammability rating as measured according to ASTM D4986.

An enclosure member for a building structure comprising a planar laminate having a first facing layer; a layer of foam having a first face and a second opposing face; and a second facing layer; where the first facing layer is fastened to the first face of the layer of foam, and the second facing layer is fastened to the second opposing face of the layer of foam. An edge of the enclosure is provided with a perimeter structure that can perform one or more of a sealing function, an edge reinforcement function and a pivotable joining function with another enclosure, in accordance with the particular embodiment.

A foldable building structure is provided that includes a fixed space portion including a first floor portion, a first ceiling portion, a first wall portion rigidly secured to the first floor portion and the first ceiling portion. The foldable building structure includes a second wall portion which is movable between a folded position and a deployed position, and a third wall portion which movable between a folded position and a deployed position. The second and third wall portions when in their deployed positions form with the first wall portion a first wall component of the foldable building structure. The second wall portion is capable of being moved between the folded position and the deployed position without moving the third wall portion between the folded position and the deployed position.

The disclosure relates to acoustic panels and methods for preparing them. The disclosure relates more particularly to panels having a porous facing and to methods for making such panels. One aspect of the disclosure is an acoustic panel comprising a base structure. The base structure has one or more edges, an outward major surface having a total area, and an inward major surface opposing the outward major surface. The base structure has a noise reduction coefficient (NRC) of at least about 0.3. The panel includes a coating layer directly disposed on the outward major surface of the base structure, the coating layer being formed of an open-cell foam. The coating layer has an exterior major surface opposing the outward major surface of the base structure. The coating layer is substantially scattering for light in the wavelength range of 380 nm to 780 nm, and has an absorption coefficient of less than 0.5 for acoustic frequencies in the range of 100 Hz to 10,000 Hz.

A vibration absorption device for acoustic insulation for a building structure comprises an absorbent cushion and a vibration isolation cushion. The building structure is selected from a ceiling structure, a floor structure and a partitioning structure separating two adjacent building compartments or a building compartment and the external environment. The absorbent cushion comprises sound absorbing material and the vibration isolation cushion comprising vibration isolation material. The vibration isolation cushion overlies and is laminated to the absorbent cushion. The vibration isolation cushion is rigid relative to the absorbent cushion. The absorbent cushion is supple relative to the vibration isolation cushion. The vibration absorption device is mountable to the building structure, to isolate vibrations and to provide acoustic insulation between the two separated and adjacent building compartments.

A composite foam article is disclosed herein. The composite foam article comprises a polyurethane foam core presenting a first surface and a second surface facing opposite the first surface. A first skin is disposed on the first surface and a second skin is disposed on the second surface. The polyurethane foam core has a density of 15-80 kg/m.sup.3. The first and second skins comprise a plurality of fibers and a polymeric binder. The composite foam article has a weight per unit area of 500-1000 g/m.sup.2 and a strength of greater than 17 N at a post-compression thickness of greater than 2 mm when tested in according with SAE J949 at 23° C.

A vehicle trim element having at least one coating layer that includes a main layer of a composition having at least natural fibers, a thermoplastic polymer, and a binding agent. The fibers and thermoplastic polymer are ground to form an assembly of particles each having a size substantially between 0.1 and 3.2 mm. The particle assembly is mixed and compressed with the binding agent.

The invention is drawn to flexible self-adhesive mineral wool laminate, comprising—a mineral wool insulation mat with a first and second main face, —a first facing laminated onto the first main face of the mineral wool insulation mat, —a second facing which is a double-sided adhesive structure adhered with one if its adhesive faces to the second main face of the mineral wool insulation mat, the other adhesive face being made of or comprising a pressure sensitive adhesive, the laminate being characterized by the fact that the double-sided adhesive structure comprises a plurality of through-holes, and to use of such laminates for insulating metallic sheet ducts or cavities.

A molding based on a monolithic organic aerogel has a density in the range from 60 to 300 kg/m.sup.3 and a thermal conductivity in the range from 12 to 17.8 mW/m*K.
