ASTRO-TAB
The
Best Choice for Insulating Below Hydronic Floor Heating Systems
|
Applications:
- I Joists 16"
ASTRO-TAB between bottom caps 17" ASTRO-TAB between the webs.
- Solid Lumber
Joists 16" ASTRO-TAB.
- Truss Joists 17"
ASTRO-TAB between bottom flanges or cut to fit.
Note:
When insulating above crawl space or an unfinished basement,
ASTRO-FOIL can be stapled along or across the bottom face of
the floor joists. 48" or 72" wide material is preferred for that
application. Use 2" wide ASTRO-FOIL tape at all seams to create
a vapor barrier. |

Behind Stacks
|
Installation
Guidelines:
- Use 16" wide
ASTRO-TAB to fit between wall studs on 16" centers.
- Push ASTRO-TAB
against the sheathing and staple through the tabs every 18" to
24".
- Install stack
over the ASTRO-TAB. For maximum thermal performance leave a
3/4" air space between the stack and the ASTRO-TAB.

Return Air Panning Systems
|
Installation
Guidelines:
- Use 16" wide
ASTRO-TAB when floor joists are on 16" centers and 24" ASTRO-TAB
for joists on 24" centers. For double panning adjacent
cavities use 34" wide ASTRO-TAB. Cut tabs same distance from
the end of the ASTRO-TAB as the depth of the joist.
- Slide ASTRO-TAB
up between floor joists and staple to the rim joist below the
register opening. If run begins away from the rim joist, bend
a 1" strip along the beginning edge of the ASTRO-TAB and
staple to sub floor. Staple the tabs to the floor joists.
- Bring the ASTRO-TAB
up with the tabs over the bottom face of the floor joists.
Staple every 2" - 3". If preferred, the tabs can be bent down
and the ASTRO-TAB slid up 3/4" between the floor joists.
Staple every 2" - 3" to the bottom inside of the joists.
