While a typical 38mm (3.5-inch) of insulation in a stud wall has an R-value of 13, using 38mm (3½- inches) of Thermablok® could produce an amazing R-value of 105 in the same space.
The majority of thermal transmission in a standard insulated stud wall travels through the mechanical link, usually the studs. Thermablok, which is 99.8% air, interrupts this thermal path quickly and economically. Installation of the product is accomplished by attaching Thermablok to the stud edge before drywall or sheeting is put up. Thermablok comes with a simple pull and stick adhesive back for easy, clean installation. No messy adhesives required.
Thermablok technology couldn’t have been made available to the public at a better time. Conservation is of course faster, and much less expensive than producing more energy.
Other benefits include:
- Significant saving in energy costs
- Unaffected by moisture, mold or water
- Easily applied via stick-on back.
- “Class A” fire rated
- Adds acoustical isolation
- Made in USA
- Virtually no weight means low cost shipping
Thermablok® Installation Instructions
Thermablok Thermal Strip Insulation
Peel & Stick Adhesive Backing
Thermablok may be installed either on the exterior or interior side of the wall framing. Insulate the full length of framing members. Apply to all wall, floor or ceiling framing edges: headers, footers, trusses, window and door frames, floor joist and roof rafters.
It is suggested that Thermablok be applied to the exterior side of the assembly, if:
- You have access to entire building envelope, between floor joists and other areas not accessible from the inside.
- With metal framing you are able to create a warm stud, preventing condensation.
Cut and fit Thermablok 38 mm (1-1/2″) wide encapsulated strips tight to any protrusions or interruptions to the insulation plane. Butt edges and ends of Thermablok thermal bridging barrier insulation tightly to each other without gaps.
Remove release backing from adhesive tape on Thermablok thermal bridging barrier insulation, and apply directly to either metal or wood framing. For wood framing you may use a staple hammer with applicable length staples.
Install On All Framing Edges
Immediately following application of self-adhering Thermablok, press thermal bridging barrier strip firmly and uniformly to substrate surfaces to insure adhesion.
Install covering materials wall, roof, sheathing, plaster lathe or gypsum wallboard in accordance with guidelines.
Plan and Coordinate the Thermablok aerogel insulation work to minimize the generation of off-cuts and waste. Reuse Thermablok off-cuts to the maximum extent possible.
Do not install self-adhering Thermablok thermal bridging barrier insulation when temperature or weather conditions are detrimental to successful installation.
Thermablok non-encapsulated strips (aerogel composite material without polymer wrapping) attaches with an appropriate construction grade adhesive per the adhesive manufacturer’s instructions, or with any appropriate substrate fastener. Observe handling precautions per MSDS.
Thermablok Blanket Insulation Installation
Do not install Thermablok and new siding over walls that have deteriorated from moisture, insects, etc. Repair unsound walls prior to proceeding.
Thermablok Installation with Mesh
Plan and coordinate the thermal bridging barrier insulation work to minimize the generation of off-cuts and waste. Reuse Thermablok blanket material cuts to the maximum extent feasible.
Precut lengths in work staging area. Thermablok may be cut with scissors, hot knife, or utility knife. Observe handling precautions per MSDS.
Attach Thermablok with an appropriate construction grade adhesive following the adhesive manufacturer’s instructions.
As an alternative to adhesive, appropriate masonry or sheathing fasteners equipped with 25 mm (1″) dia. mushroom caps; spaced 30.5 mm (12″) to 40 cm (16″) in any direction, can be used to attach the Thermablok to the masonry.
Take care to insure the edges of adjacent sections of Thermablok are tightly butted together.
Entire Wall Installation
Cut Thermablok to fit tightly around windows and doors. Cut flush to edge of framing.
Beneath radiant heat floor systems and basement floor to increase thermal efficiency. Simply roll out and spot tack material into place.
Read before Installation
Thermablok can be cut using conventional textile cutting tools including scissors, electric scissors, and razor knives. The material can be dusty, and it is recommended gloves, safety glasses, and dust mask be worn when handling material.
Download MSDS [PDF] for complete health and safety information. Long sleeved, long legged work clothes that cover any exposed skin are recommended when handling the blanket material which is not encased in the plastic sleeve.
