1. Prep work area

• Move shelving, and all household items away from wall to be insulated.

• With clients permission, remove any fixtures from the wall such as shelving and decorations that can be easily removed.

• Remove any foundation ties or other obstructions that could damage pin n drape materials.

2. Air seal wall & sill

• Follow work orders and guidance in Air Seal Basement or Crawl walls to complete air sealing of wall and sill prior to installing insulation

3. Install insulation

• Follow work orders and step 3a-3f to install insulation.

3.a Minimum 30 year life

• Materials shall be installed to have a minimum expected service life of 30 years.

3b. Insulation R-value

• Install insulation with the R-value specified on work orders to improve the thermal performance of the basement or crawlspace.

3c. Install continuous air barrier on warm side of insulation

• Install a continuous air barrier on the interior (warm) side of the insulation to allow insulation to dry to the interior of the home, to prevent condensation on the basement wall, and to increase durability of the measure.

• Vapor barrier must be durable, and vapor permeable such as Tyvek™ HomeWrap, or perforated vinyl or similar.

3d. Ensure continuous insulation

• Install insulation so that the thermal barrier is as complete and continuous as possible across the surface of the wall.

• Insulate all the way to the corners, floor and ceiling.

3e. Align new insulation with existing

• Align or abut new insulation with existing insulation to create a continuous thermal barrier with minimal breaks.

3f. Install on thermal boundary only

• Only walls on the thermal boundary of the dwelling should be insulated.

• If you are unsure about where the thermal boundary is being established, consult with the energy auditor.

4. Secure insulation to wall

• Use the methods in steps 4a-4d to secure the insulation to the wall

4a. Fasten with furring strips

• Install furring strips around windows, doorways, and other openings in the thermal boundary to attach insulation to.

• Attach air barrier to the furring strips using staples or other mechanical fasteners to ensure a durable installation that will last the life of the measure.

4b. Fasten with insulation pins

• Install insulation pins, per manufacturer's specs, to attach insulation to the wall with a durable connection and prevent insulation from sagging or moving.

• Use the appropriate length of pins to prevent compression of batts

4c. Tape all seams

• Overlap and tape all seams on the air barrier to provide a continuous barrier.

• Use only manufacturer approved tapes.

• Tape should not be used to secure the insulation to other substrates like the foundation, framing members, or furring strips. Mechanical fasteners should be used for these connections

4d. Cover electrical and plumbing lines

• Insulation should cover existing electrical wires (except knob and tube), and plumbing drain lines that are fastened to the wall.

5. Insulate around supply lines

• Select the best option from steps 5a-5c to address each supply line on the wall being insulated.

5a. Move supply lines into envelope

• Whenever possible move the supply lines in front of insulation to keep them in the envelope to prevent freezing

5b. Insulate plumbing supply lines

• Use pipe wrap to insulate supply lines that are secured to the wall.

• If it is not possible to insulate or bring supply lines into the envelope, then install a break in the insulation

6. Fit insulation around windows and access points

• Follow Steps 6a-6f to fit insulation around windows, doors and utility access points.

• Insulation shall fitted be securely affixed around windows, doors, electrical boxes, and plumbing cleanouts and valves.

• Windows and access points should be accessible, with a minimal break in the thermal boundary.

6a. Trim the insulation

• Trim the Insulation out of the window or other openings in the thermal boundary.

6b. Cut the air barrier

• Cut the air barrier where it covers the window, or other openings in the thermal boundary.

• Use a diagonal cut from the top corner of the cutout to bottom. Then cut from opposite corners creating an X.

6c. Secure insulation

• Use furring strips and/or Insulation pins to secure assembly to wall, to prevent it from detaching from the foundation wall.

6d. Wrap exposed insulation

• Use the flaps from the house wrap to cover the exposed insulation around the edge of the window or opening in thermal boundary.

• Tape the corners to cover any insulation still exposed.

6e. Secure air barrier with staples

• Secure the air barrier to the furring strips with staples or other mechanical fasteners.

• Tapes tend to fail here and should not be used unless also mechanically fastened

6f. Avoid compressing insulation

• Avoid unnecessary compression of the insulation near the edges and around access points to maximize overall r-value.

7. Pin and Drape on sill

• In some situations the wall insulation can also be used to insulate the sill. Follow steps 7a-7e to install this method.

7a. Run wall insulation to the floor above

• Install insulation on wall with enough excess insulation to cover the sill.

7b. Trim around floor joists

• Trim the house wrap, insulation and vapor retarder to fit around the floor joists

7c. Ensure alignment with air barrier

• Install insulation on wall and sill in a manner that prevents air gaps between the insulation assembly and the wall and sill.

7d. Fasten house wrap to floor and joists

• Use staples or similar to secure the housewrap to the floor above the sill, and to the sides of each floor joist.

8. Install Insulation Certificate

• A dated insulation certificate signed by the installer will be posted on a wall in the space where the furnace is located, a utility room or an approved location inside the building.

• Certificate shall include: Insulation Type, Coverage Area, installed thickness and minimum settled thickness, Number of bags installed in accordance with manufacturer specifications

9. Client education

• Educate the client on use and care of newly installed Insulation.
