For over 30 years we have developed and promoted high R-value insulation systems in metal buildings.

We believed there had to be a better way to insulate without the traditional methods with so much insulation compression. We would never insulate our homes this way, so why be forced to insulate your metal building this way? The Simple Saver System® is an inexpensive and effective method to create the space needed for full specified insulation thickness in roofs and walls.

 

Simple Saver Roof Performance Values

The Simple Saver Roof System is a patented fabric liner insulation system that minimizes insulation compression and isolates the conductive purlins from the inside conditioned air. The Syseal® fabric liner spans the entire bay’s width and length and is supported by a grid pattern of UVMAX® coated steel straps installed below the purlins. This creates the uniform depth space for full insulation thickness between the purlins. The top layer of insulation is draped over purlins and compressed when the metal roof panels are attached.

Double Layer Roof Systems

Simple Saver System with two layers of fiber glass insulationIn new construction projects, a double layer Simple Saver is certainly the most common option specified. The bottom layer of fiberglass is installed parallel and between and purlins and the upper layer of fiberglass is installed perpendicular and atop the purlins. The upper layer of fiberglass between the roof sheets and the purlins serve as a thermal break to reduce thermal conduction, in addition to the thermal spacer block if applicable in standing seam roofs. Double layer systems are used in screw down roofs, standing seam roofs with or without thermal spacer blocks. Additional multilayer systems can also be achieved with multiple thick layers of fiberglass between the purlins (when cavity space is available) and an upper layer installed perpendicular to the purlins.

Single Layer Roof Systems

Simple Saver System with one layer of fiber glass insulation A very thick layer of fiberglass insulation can be installed parallel and between the purlins and used in a single layer Simple Saver roof as long as it adequately fills the cavity space. If a single layer system is selected for new construction, we encourage the fiberglass insulation to be in contact with the bottom of the metal roof sheet. Single layer systems are more common in screw down roofs vs. standing seam roofs which has the additional clip space above the purlin. Considering there isn't an upper layer of fiberglass, Thermal Design recommends our Quik-Stop™ thermal break foam tape between the roof sheet and the purlin to reduce thermal conduction.

Blown-in Systems

Simple Saver System with blown in insulation Considering the Simple Saver System is a suspended support roof system for insulation, it provides the option utilizing a range of insulation materials such as blown insulation or cellulose. Blown-in systems fill cracks and crevices within the cavity that helps reach maximum thermal performance and dramatically increases installation productivity in retrofit applications. Special equipment and installation experience may be required with blown-in systems. Considering there isn't an upper layer of fiberglass, Thermal Design recommends our Quik-Stop™ thermal break foam tape between the roof sheet and the purlin to reduce thermal conduction. Contact Thermal Design for more details on application and blower equipment rentals.

Simple Saver System wall sideviewSimple Saver Wall Performance Values

The Simple Saver Wall System is a high performance insulation system for metal building walls that maximizes the unfaced metal building fiberglass insulation in the cavity space by allowing the fiber glass to maintain full designed thickness. The Syseal® fabric liner is made up of a large custom sized piece to neatly fit each wall bay area, isolating the insulation and conductive girts from the inside conditioned space. The fabric is sealed and then mechanically fastened using UVMAX® coated steel straps with color matching self drilling fasteners around the perimeter and at intermediate girts. The Simple Saver System is typically left exposed to the interior for a bright clean finish.

Testing and Modeling Thermal Performance

Thermal Design, Inc. has invested a considerable amount of time and research over the past two decades on the insulation methods and performance expectations for metal building roof and wall assemblies. Beginning in 2005, the Buildings Technology Center at the Oak Ridge National Laboratory (ORNL) in Oak Ridge, TN performed steady-state guarded hot box tests in its Large Scale Climate Simulator (LSCS) on Thermal Design’s Simple Saver System® as well as other metal building insulation methods. Additional guarded hot box tests and expanded assembly types were conducted at Johns Manville Technical Center in Littleton, CO. Tests were in accordance with ASTM C-1363, “Standard Test Method for the Thermal Performance of Building Assemblies by Means of a Hot Box Apparatus”.

Based on the research and tests preformed, Thermal Design, Inc. has the capability of running finite element modeling with a high confidence of accuracy to determine the thermal performance of similar installed assemblies. Please contact Thermal Design Research (800.255.0776 or email research@thermaldesign.com) for specific modelling on your project.

Test results apply exclusively to Simple Saver System® components by Thermal Design, Inc. Unauthorized use is prohibited. See installation instructions for further information on how to properly install the Simple Saver System to achieve the best results. Every effort was made to ensure that the test assembly was representative of typical construction practices. However, normal manufacturing variation of materials, building design and workmanship may yield performance that differs from these results. Thermal Design, Inc. continues to perform extensive research on the thermal performance of metal buildings.

Design Manual and Instructions

Thermal Design provides detailed, custom project drawings for the insulation systems provided in each building. Specific strap and fastener locations, bay spacings, fabric sizes and exact insulation sizes and placements are provided. Thermal Design provides some of the most detailed installation system instructions in the industry for pre-engineered metal buildings with C or Z purlins or bar joists. Instructions for post frame or hard wall structures are also available. It's important to follow the complete manufacturer installation instructions for the Simple Saver System® to achieve a safe, effective installation.
