Order this productThe base layer consists of a non‑woven polyester‑glass fiber mat impregnated with a water‑based acrylic resin. This combination yields a tensile strength of approximately 12 MPa and an elongation at break of 15 % under ASTM D882 testing. The surface finish is a pigmented polyurethane coating that provides a hardness of 2H on the pencil scale and a gloss level adjustable between 5 % and 85 % depending on the topcoat formulation.
Standard thicknesses range from 0.5 mm for lightweight acoustic panels to 2.0 mm for high‑impact commercial applications. Corresponding areal weights fall between 120 g/m² and 380 g/m², allowing selection based on load‑bearing requirements of the substrate. The product adheres to gypsum board, cementitious backer board, and primed metal studs when using a compatible pressure‑sensitive adhesive with a shear strength of at least 0.4 MPa.
When tested according to ASTM E84, the wall covering achieves a Class A flame spread index of 20 or lower and a smoke developed index of 45 or lower. The water‑based resin system limits volatile organic compound content to less than 30 g/L, meeting California CDPH Standard Method v1.2 for low‑emitting materials. These values are verified per batch using gas chromatography‑mass spectrometry.
The porous mat structure provides a noise reduction coefficient (NRC) of up to 0.35 in the 250 Hz–2 kHz range when installed with an air gap of 10 mm. Thermal conductivity measures approximately 0.045 W/(m·K), contributing a modest R‑value improvement of 0.025 m²·K/W per millimeter of thickness. These characteristics support compliance with indoor environmental quality criteria in LEED v4.1.

Adhesive selection should match substrate porosity; a low‑viscosity acrylic‑based adhesive with open time of 15 minutes is recommended for gypsum board, while a modified silane polymer works better on metal studs. Seam overlap of 50 mm ensures continuity of pattern and prevents edge lifting under cyclic humidity changes. Roller pressure of 0.2 MPa applied during bonding achieves optimal wet‑out without damaging the surface coating.
Each roll undergoes inline thickness measurement with a laser micrometer (±0.01 mm accuracy) and surface gloss verification using a 60° gloss meter. Random samples are subjected to accelerated weathering (UV‑B, 8 hr cycle) to confirm color stability ΔE<5 after 500 hours. Final inspection includes visual defect classification per ISO 12944‑2, with acceptance limited to ≤2 defects per m².
Width can be supplied in rolls from 0.9 m to 1.5 m; length is cut to project‑specific panels with a tolerance of ±2 mm.
