2. Wall – Masonry R-3.7 and R-7.0

  • Refer to the Reflectix® Webpage “DIY Wall – Masonry”.

3. Wall – 2”x 4” R-6.6 (no fiberglass)

  • Determine if studs are 16” or 24” on center (This will determine whether Reflectix® 16” or 24” product is utilized).
  • Place one corner edge of the Reflectix® in an upper corner of the stud cavity. At a point that splits the stud cavity; staple the product to the side of the stud (creating a 3/4” tab on the product).
  • Proceed “down”, stapling to the side of the stud every 2″- 3”.
  • Repeat procedure on opposite stud.
  • The Goal: Create two approximately equal continuous 1 3/4” air spaces on each side of the Reflectix® Insulation.
  • This application also provides a vapor/moisture barrier.
  • Finish wall interior with a panel or sheathing (Product is not specified as an interior wall covering).

Review These Important Safety Guidelines Prior to Installation:

  • ALWAYS check local building codes before installing Reflectix®.
  • ALWAYS check the area you are insulating and make any needed repairs. Any worn wiring should be replaced before you begin installing Reflectix®.
  • ALWAYS make sure work areas are well ventilated and well lighted.
  • ALWAYS use eye protection when operating a staple gun.
  • ALWAYS use caution and common sense when using a staple gun. Be aware of electrical wiring locations. Stapling into a wire can cause severe shock or death. NEVER staple into electrical wiring.

  • When installing Reflectix® on bright sunny days, it is best to wear sun glasses.
  • Do not work in areas such as attics when temperatures are too hot.
