Good Looks – Great Sound, throughout.

The whole idea behind the Even Better system is to unify design and acoustics, eliminating unnecessary compromises in the design process. Making things simpler for everyone involved, from architects, designers and contractors to clients and end-users.

Install it on walls and ceilings. On flat, curved or vaulted surfaces. Seamless, with no upper limit for how large a surface can be in a single section. Play with color, play with texture. No compromises, no special adaptations; quicker, easier, better – Even Better to put it simply.

How does Fellert stack up against the competition?

While the most acoustical plaster manufacturers provide an acceptable product, Fellert has the fortunate advantage of not only being the most flexible system and easiest to install - but also the highest rated acoustical absorption (NRC) by ASTM standards.

Classic Finishes

Silk, Sahara, Secern. Our standard line of finishes vary in smoothness. Our silk finish is most popular, with a completely monolithic "sheetrock" type look. These finishes can be painted to match any Benjamin Moore or Sherwood Williams paint color. View dimensions, installation, fire safety information, cleaning and repair, sound absorption and more.

Designer Finishes

Concrete, Stone, Marble. Fellert's newest line of finishes are made to match these materials. Currently the only manufacturer of these specialty finishes, we are giving architects, owners, and consultants more flexibility in their work flow. View dimensions, installation, fire safety information, cleaning and repair, sound absorption and more.

Certifications and Sustainability

Fire testing, mold resistance, VOC emissions, light reflectance (LR), elasticity, compression strength, health product declaration (HPD) and LEED statement.
