The wall applications developed by SR Contractors use the properties of SR Foam to provide strength for structural loading while also improving the insulation performance of the structure. The final result is a tested system that can be installed in a variety of wall applications with less labor requirements than alternative methods and provide both structural and thermal improvements to the building.
BSW Wall Systems
The BSW Wall System is an application of SR Foam that is intended to provide support to masonry or concrete walls that are loaded both with seismic forces and soil back fill loads. In some situations these are full height basement walls, but the they can also be partial height walls between basement and crawlspace areas. In the BSW Wall System, SR Foam acts as both a bearing and tension element that transfers the design forces either applied to or from the concrete or masonry to the new wood or steel stud framed wall assembly. The BSW walls are sheathed on the side closest to the concrete or masonry to provide a backing surface to restrain the foam expansion. The wall sheathing can also be designed to make new the wall assembly a shear wall to resist in-plane lateral design forces.
BW Wall Systems
The BW Wall System is intended to provide reinforcing for un-reinforced and under-reinforced masonry and concrete walls that are fully above grade. This system consists of a conventionally framed wall constructed with wood or metal studs and plywood sheathing on the surface between the stud wall and concrete or masonry. The supporting wall is constructed on the ground horizontally, slightly shorter than the required height, then stood into place and shimmed as required at the top. The new wall assembly is then bonded to the existing concrete or masonry material using SR Foam. The conventionally framed wall can be designed and detailed to resist in-plane forces, acting as a shear wall, and to support out-of-plane wall loading. SR Foam provides a continuous bond between the conventionally framed wall and the concrete or masonry to restrain and support the existing concrete or masonry elements. The BW Wall System is an alternative to the discrete fastener attachment methods on the market and reduces installation time and labor costs on a project, when compared to the alternatives.
MCE Wall System
The MCE Wall System is a unique solution to provide effective seismic strengthening for clay tile and other masonry walls that have an internal cavity that ranges from 2" to 24" wide. SR Foam is injected in the cavity between the two wall elements, creating a section of the wall that is ductile in tension. The addition of a ductile section to the wall assembly allows it to be analyzed as a composite section for seismic or other short term loading. This method also allows the SR Foam to bond to the masonry, limiting cracking and spalling during a seismic event. The MCE Wall System requires no form work or external structural support to provide lateral stability, allowing the designer to maintain the existing finished floor area. Competing seismic reinforcing systems will require additional costs for framing or forming to be installed. The MCE wall is unique in its approach to resolving the concerns of this wall type since there is no impact to the existing finishes, given access from the roof or other interspatial space is available, and installation does not reduce the available floor area of the building.
SR Veneer Attachment
The SR Veneer Attachment uses SR Foam as a continuous adhesive layer between the structural wall and the veneer. The installation of SR Foam replaces the use of the metal clips and bonds veneer continuously to the supporting substrate. Additionally, the SR Veneer System increases the insulation properties of the building while helping reduce air infiltration by forming a continuous vapor barrier behind the veneer. While the installation is most efficient during new construction, it can be installed after construction or as a additional measure if the original clips are insufficient or deteriorating.
TR Wall System
The TR Wall System is used in situations where high strength resistance to in- and out-of-plane loads and increasing insulation to meet building code requirements are necessary. The TR Wall System is also well suited where the supporting wall needs to be built to the full height vertically and cannot be constructed horizontally on the ground and lifted in place due to floor space constraints or wall bearing requirements. The TR Wall System consists of a structural wall with sheathing on the interior face, as shown graphically below. The SR Foam is installed in the resulting cavity behind the sheathing, filling between and behind the studs, to the original concrete or masonry wall. The TR Wall System provides exceptional vertical and horizontal load capacity by providing a highly adhesive bond to the original wall material and substantial lateral bracing for reinforcing the new wall studs, while also providing code required, or better, insulation R-values.
