Wall Insulation Project: How We Reduced Room Temperature by 30°F
Our client contacted us with a serious problem: the bedroom was overheating from direct sunlight, the walls were hot to the touch, and it was almost impossible to sleep comfortably.

After inspection, we discovered the main issue — the walls had no insulation at all. This was the reason why the room absorbed and retained so much heat.
⸻
Step 1. Diagnosis
We used a special inspection camera to check the inside of the walls. The test confirmed our assumption: there was no insulation in any of the walls.
⸻
Step 2. Cost-Effective Wall Opening
Instead of fully tearing down the walls, we suggested a more economical method:
• cutting small horizontal openings in the middle of the wall,
• inserting insulation both upward to the ceiling and downward to the floor through these openings.
This approach allowed us to insulate the walls completely while keeping most of the structure intact. It also saved the client both money and time compared to a full demolition.
⸻
Step 3. Installing the Insulation
Through the prepared openings, we installed modern insulation with excellent thermal and soundproofing qualities.
The insulation completely filled the wall cavities, preventing heat transfer from the sun.
⸻
Step 4. Wall Restoration
After installing the insulation, we:
• sealed the openings,
• applied joint compound,
• prepared the walls for painting.
The walls were restored to a clean, finished look without visible damage.

Results
After the project, wall temperature dropped by 30°F, and the room felt noticeably cooler, even during sunny hours of the day.

Why This Method Is Smart
• Cost-effective — no need to open the entire wall surface.
• Comfort — cooler in the summer, warmer in the winter.
• Energy efficiency — reduced load on AC and heating systems, lowering utility bills.
• Aesthetics — walls look like new after restoration.

Tips for Homeowners
1. If your walls get very hot from the sun, they might be uninsulated.
2. You don’t need to open the entire wall — modern insulation techniques allow full coverage through small openings.
3. Always restore and seal the walls after installation to maintain protection and appearance.
4. Insulation is not just about comfort — it’s also a long-term investment in energy savings.
