Triple Extrusion Welded Seams
Thermal Design features the industry leading, factory-made, triple extrusion welding seaming process which ensures proper seam strength, durability, appearance and is uniquely pressure resistant to assure very low vapor permeance. Ideal for minimizing air infiltration and maintaining vapor retarder integrity throughout the envelope assembly as apposed to thousands of staple holes or hidden, unsealed lap joints typical with faced insulation and on-site seaming methods.



Syseal® Fabric Colors
Thermal Design provides more color design options compared to anyone in the industry and takes great pride in quality control to provide a consistent, reliable product. Syseal White has certainly been the most popular for standard applications over our past couple decades. Athletic facilities and lighting enthusiast are especially fond of our Syseal Super White because of the high reflectance features; while Syseal Black will remain the favorite option to make the ceiling visually disappear in desired applications. Syseal Silver Aspen and Toni Taupe™ are increasing in popularity because of their uniqueness and the cost savings it provides eliminating the need for painting and finishing.

Custom color fabric information is available upon request. Unique color schemes of fabric and/or UVMAX strap are design options available for specifiers. Thermal Design does not recommend painting the Syseal fabric.

Perforated Syseal® Fabric (optional)
Depending on the needs and placement of the vapor retarder, the Syseal® fabric may also be perforated, and not serve as a vapor retarder for unique building conditions. Upon request, Thermal Design provides custom sized fabric pieces that are perforated with 3/16” minimum holes spaced not more than four inches apart in each direction. Our perforated fabric has been a popular choice for facilities that feature indoor sheets of ice (hockey, curling, etc). The needs for this type of building are unique and Thermal Design provides a variety of design solutions.

Fast-R Hanger Fast-R wall insulation hangers are 23.5" long, galvanized preformed steel strips with punched barbed arrows centrally located every eight inches. The Fast-R hangers are hung in the wall cavity between the girts and wall panels. Unfaced, uncompressed fiber glass insulation is impaled onto the arrows. This holds the insulation in a permanent position and retains the fiber glass shape and position within the girt cavity. Narrow girt spaces, such as 24", may not require hangers if insulation will support itself.

Snap-R Thermal BlockSnap-R thermal spacer blocks are constructed of polystyrene material and shaped differently than the typical thermal spacer blocks supplied by the building manufacturer. Our unique design allows the installer to snap the thermal block onto the purlin (or girt) flange and not have to worry about wind blowing them away during installation. In fact, in most situations, the installer can remain in one position and slide each 24” long Snap-R along the entire length of purlin.

  • Unique Design
  • Snap & Slide
  • Won't Blow Away
  • Creates Addition Cavity Space
  • Provides a Thermal Break

Installation of fiber glass insulation over Snap-R thermal block is not typically recommended. Ideal use is to create additional cavity space, typically for single layer, full thickness insulation assemblies and used on the interior or exterior flanges. The Snap-R will enhance the performance of the entire insulation assembly because it eliminates the direct contact from the steel panels and the purlin or girt, minimizing the amount of heat transfer.

Quik-Stop Trash Free

Quik-Stop Thermal Break Tape

Quik-Stop Trash Free™ thermal break tape without paper release backing, is the industry's fastest and cleanest method to install insulative foam tape on metal building purlin and girt flanges and minimizes conductive paths between metal panels and metal framing.

Thermal Design re-engineered the design and application with a direct applied special adhesive film on the inside of foam tape roll allowing the installer to easily apply to framing as it unrolls which in turn eliminates the need to peel and remove the messy paper release backing and time consuming project site clean up.

Quik-Stop Trash Free, utilized for new or retrofit applications, is available for all of Thermal Design's insulation liner systems including Simple Saver System™ and the new AutoCeil™ ceiling and wall insulation system. It is an integral part of Thermal Design's wall liner systems with metal building insulation to meet and exceed the newer, more stringent national model energy codes of 2015 IECC and ASHRAE Standard 90.1-2016 without incorporating expensive, prescriptive listed assemblies featuring “ci” continuous insulation.

The Simple Saver System has a variety of different sealants to recommend depending on the building structure, conditions, building use and requirements. They are used to seal the fabric liner (vapor retarder) perimeter edges to the abutting main frames and eave struts. Thermal Design has spent a tremendous amount of research and testing to determine which is the most effective, yet economical sealant for the insulation system. Substituting sealants not quality controlled by Thermal Design is not recommended and may void warranty.

Syseal® Repair Tape

Syseal Reapir Tape Mistakes happen – don't worry. Syseal® Repair Tape is an adhesive backed material made out of the Syseal® fabric liner materials used in Thermal Design's fabric liner systems. They are the same Class A FHC (Fire Hazard Classification) grade of fabric and of comparable strength, although there may be very slight variations in color that exist. Our quality control objective is to match the grade and color as closely as processes allow (Syseal® White, Super White, Silver Aspen, Black, Toni Taupe™). While most applications and installations will require very little repair tape, it comes in handy for correcting over cutting slits and patching puncture holes. In addition, it may be necessary to use repair tape when installing around welded bracing or other protrusions that can not be disconnected and reattached.

Our plated, self-drilling fasteners are color matched with each liner system order. Fasteners that accompany the Simple Saver System™, feature a color matched sealing washer as well. Special fasteners for wood, concrete and other structure types are available from Thermal Design and should be used when appropriate. We offer over a dozen different fastener types depending on your installation need. Contact Thermal Design for special stand-off fasteners for additional insulation thicknesses.

Brace Clips

  • Reliable Seal
  • Faster Installation
  • Clean Look

Preserving the integrity of the Syseal® vapor retarder around rafter bracing can be easily accomplished using approved 90º rafter brace clips fastened to the bottom of the purlin flange. This type of connection provides a reliable seal and speeds installation because it eliminates the need to slit the vapor retarder where the rafter brace would normally protrude through the bottom plane of purlin.

Stock clips are 14 gauge. Also available in other gauges and in other lengths by special order. Standard finish colors for brace clips are powder coated white and black, four (4) color matched fasteners are included with each clip.

Rafter brace clip detail

Consult your building manufacturer for brace clip structural requirements before installation and use of these alternative brace clips. Many building manufactures have their own preferred brace clip designs for use with liner systems.

 Additional connection options  are available upon request and detailed in the Simple Saver System™ Design Manual. These fastening methods are routinely approved by building manufacturers for use with Thermal Design's Simple Saver System. Contractors need to consult the building manufacturer for brace clip and connection requirements.
