“The solutions from Sto enabled us to keep the exterior envelope intact so we avoided energy and water intrusion concerns. We were able to dress up the exterior without being invasive or labor intensive. The grid system allowed the freedom to choose sizes and colors to create our vision with a unique pattern.”

The most versatile Rainscreen® system available.

From fiber cement panels to glass, masonry, and render, our StoVentec® Rainscreen® systems provide a vast array of colors, textures, and shapes, combined with recognized compliance under AAMA and NFPA standards – delivering the proven versatility and performance architects trust.

StoVentec® Fiber Cement: Versatile, lightweight, integrated

StoVentec® Fiber Cement is our durable, drained, and back-ventilated Rainscreen® system with four key components: an air and water-resistive barrier, adjustable sub-construction, thermal insulation, and prefinished high-density fiber cement cladding. Covered by Sto Corp.’s single-source warranty, it offers a variety of finishes, colors, and textures. With exceptional wind load resistance and low maintenance, this code-compliant cladding ensures timeless aesthetics and versatile performance.

System Components:

  1. Air and Water-Resistive Barrier – Sto AirSeal® is a fluid-applied air and water-resistive barrier that protects walls from moisture, provides secondary protection, and ensures air barrier continuity with excellent tensile elongation and code compliance.
  2. Thermal Insulation – StoVentec® Fiber Cement uses ROCKWOOL® Cavityrock® insulation for exceptional thermal performance, fire resistance, sound control, and moisture resistance, with thermal modeling to meet energy code requirements.
  3. StoVentro™ Sub-Construction – StoVentro™ sub-construction forms the structural link between the façade and base wall, offering design flexibility, ventilation, and drainage while leveling walls and enabling creative architectural designs.
  4. Standard or Custom Panels – Sto Fiber Cement high-density panels are available in standard or customized options, can be installed horizontally or vertically using visible fastener or concealed hanger for unique, durable facade designs.

StoVentec®Glass: Smooth, reflective, brilliant

StoVentec Glass is a ventilated Rainscreen wall system consisting of durable, opaque glass-faced panels, thermal insulation, sub-construction, and a continuous air and water-resistive barrier. Cladding panels faced with back-painted or digitally-printed glass are available in a wide range of sizes and in 66 standard colors.

System Components:

  1. StoGuard® air and water-resistive barrier – Featuring Sto AirSeal® the StoGuard® system provides seamless and fully integrated air and moisture control.
  2. Thermal Insulation – StoVentec Glass uses ROCKWOOL® Cavityrock® for exceptional thermal performance, fire resistance, sound control, and moisture resistance, with thermal modeling to meet energy code requirements.
  3. StoVentro™ Sub-Construction – An engineered system consisting of StoVentro Brackets with vertical and horizontal StoVentro T-Profiles to provide the structural link between the facade and supporting wall construction.
  4. StoVentro™ Agraffe Profiles – Part of the StoVentro sub-construction system, StoVentro Agraffe Profiles allow for quick and simple onsite installation of glass panels.
  5. StoVentec® Glass Panel – A composite panel with opaque glass fully bonded to StoVentec Carrier Board A+; a backing board made of 96% recycled glass.

StoVentec for masonry veneer facades: Classic looks with advanced performance

With StoVentec for masonry veneer facades drained and back-ventilated Rainscreen wall system, you achieve the classic look of masonry far faster and easier; at just a fraction of the weight; and with the advanced air, thermal, and moisture control you expect from StoVentec wall systems. StoVentec for masonry veneer facades can be used with any thin brick in conformance with applicable building code requirements.

System Components:

  1. Sto AirSeal® air and water-resistive barrier – A fluid-applied, vapor-permeable AWRB designed for use on most substrates, Sto AirSeal features a 500% elongation capacity, meets requirements of ASTM C1305, and offers building code compliance confirmed by ICC-ESR 1233.
  2. Thermal Insulation – StoVentec for masonry veneer facades uses ROCKWOOL® Cavityrock® for exceptional thermal performance, fire resistance, sound control, and moisture resistance, with thermal modeling to meet energy code requirements.
