Sound and Thermal Insulation

Light weight and soft to provide an optimum performance. Felt Vibe® Arketa Felts reduces airborne sound transmission through walls, ceilings and subfloor applications. It does not contain any formaldehyde binders commonly used with fiberglass insulation.
Arketa Felts is the perfect highly performing solution for your hotels, schools, offices, meeting rooms or commercial and residential projects where sound and noise insulation is needed.

Sound Insulation

Thermal Insulation

Sound Absorption Coefficients(as)

The Sound Absorption Coefficient is ideally defined as a fraction of the randomly incident sound power absorbed by material. The greater the coefficient, the greater the sound absorption.

SAA

The Sound Absorption Average (SAA) is a single number rating obtained by taking the arithmetical average of the absorption coefficients at 250, 500, 1000, 2000 Hz rounded to nearest multiple of 0.05.

Wall Insulation Between Rooms

Feltvibe® is ideal for reduction of airborne sound transmission between rooms through separating walls.

STC

The STC stands for Sound Transmission Class is a single number that represents the performance of the soundproofing through the air (Airborne) of walls, ceilings, doors, or by a laboratory test (standard ASTM E90-09). The values in the range of 125-4000 Hz were calculated (according to ASTM E 413-87)

In summary, the higher the STC is well soundproofed.

Excellent Thermal Insulation

Arketa Felt is also an ideal thermal insulation material for
your interior walls and ceilings in buildings and home to
help keep the interiors cooler in summer and warmer in
winter. This helps with saving energy costs by maintaining
temperature inside the building.

What is the R value of insulation
An insulating material’s resistance to conductive heat flow is
measured or rated in terms of its thermal resistance or R-value
-the higher the R-value, the greater the insulating effectiveness.
The R-value depends on the type of insulation, its thickness, and
its density.
R-Value,
Thermal resistance,
unit of : m2.K/W or ft2.h.o F/Btu
K-Value,
Thermal conductivity
unit of : W/m.K or Btu.in/ft2.h.oF
