Wall Reflective Insulation
Side Wall Application
This application utilises the properties of both mass insulation and Arctic Shield giving a superior system R-value of R-19.56. This application consists of Arctic Shield Insulation, mass insulation and rigid board. This assembly was developed to meet building codes while keeping framing costs down.
Includes ASHRAE’s standard interior & exterior air film thermal resistance values.
3.19 RSI, R-19.56
This application utilises the properties of both mass insulation and Arctic Shield giving a superior system of 3.19 RSI and R-19.56. This assembly was initially developed for the Canadian market to meet their sidewall building codes while reaching framing costs. It met with great success!
- With a conventional 2" x 4" wall, use an R-12 (2.1 RSI) friction fit fibreglass batt and exterior 1/2" rigid board. Nail 1" x 2" furring strips across the studs every 16".
- Staple Arctic Shield insulation to the furring strips using 5/16" staples. Tape all seams using Foil Tape.
- Nail a second set of 1" x 2" furring strips directly over the first set of furring strips using three #10 wood screws.
- Apply sheet rock to the furring strips using sheet rock screws.
- In this application, Arctic Shield becomes both the vapour retarder as well as an insulator.
- A helpful hint…use shallow electric boxes and install them in the last set of furring strips, then the vapour retarder will remain intact.
Alternate Side Wall Application Using Arctic Shield Staple Tab
Many contractors utilise Arctic Shield staple tab insulation in a 2" x 6" side wall cavity to avoid the application expense and labor of using furring strips. Roll widths are 16" and 24" on centre for convenience and 48" rolls are also available.
