Hourglass Block

Time flies while you’re having fun. Based on Eva’s ‘Hourglass’ Space Dividers, the more rectilinear shapes nest together to fill a wall with color and gentle, geometric zigzag patterning. Available in over ninety colors of 100% Wool Design Felt mounted to a high-performing acoustic substrate, the modular tiles install easily with heavy-duty construction adhesive while providing sound absorption and natural texture.

  • Lead Time Made to order and certain lead times will apply
  • Installation Install in the pattern as specified and attach to a wall surface using a heavy-duty construction adhesive. Tiles may be trimmed to size with a utility knife. Refer to Hourglass Block Installation Instructions for complete guidance.
  • Maintenance Vacuum occasionally to remove general air-borne debris. Should soiling occur, spot clean with mild soap and lukewarm water. Avoid aggressive rubbing as this can continue the felting process and change the surface appearance of the felt. Refer to 100% Wool Design Felt Maintenance + Cleaning for detailed care instructions.
  • Variation Wool felt is a natural material and color variation and inclusions of natural fiber on the surface are evidence of the 100% natural origin of the material. Product color is only indicative, as it is not possible to assure consistency of color in a natural product due to the natural color of raw wool and absorption of dyes. Color matching cannot be guaranteed between individual tiles and expect color variation beyond the normal commercial range.
  • Environmental 100% Wool Design Felt is 100% biodegradable/compostable and Akustika 10 contains minimum 60% post-consumer recycled content and is 100% recyclable
  • Contains no formaldehyde, 100% VOC free, no chemical irritants, and free of harmful substances
  • 100% Wool Design Felt and Akustika 10 contribute to LEED©

Eva Zeisel

Eva Zeisel was a “maker of useful things.” Born in Hungary with her early career spent in the potteries of Germany and Russia, Eva’s sensuous forms were inspired by the curves of the human body and those found in nature. Though best know for her modernist ceramics, the Eva Zeisel Collection takes inspiration from her room dividers and glazed tiles in six shapes of acoustic tiles that feature curvilinear forms nesting together to create soft, fluid patterning. In true Eva Zeisel spirit, the playful patterns may go bold with saturated colors or soft and sensual with neutral tones.
