Installation Steps:
1. Insulating the Walls:
○ Start with one wall section, beginning at the center of the back wall and working forward to the middle of the front door.
○ Repeat with the second wall section, again starting from the center of the back wall.
2. Insulating the Roof:
○ The roof insulation comes in two rolls for easier handling. Install them after completing the walls.
3. Insulating the Floor (if required):
○ Once the walls and roof are in place, apply insulation to the floor.
4. Sealing Joints & Edges:
○ Use the included silver foil joining tape to fully seal all edges and joints. Incomplete sealing can allow moisture to pass through, leading to condensation.
○ Use a strong brush to firmly secure the insulation to the walls.
IMPORTANT:
❌ Do not adhere the membrane into vertical apertures—it should lie flat against the wall. This ensures maximum thermal efficiency.
