When it comes to making your home more energy-efficient, comfortable, and quiet, wall insulation plays one of the most important roles. Many homeowners focus on attic or crawl space insulation, but the walls of your house account for a significant amount of heat loss in winter and heat gain in summer. By properly insulating your walls, you can improve indoor comfort, reduce utility bills, and even increase the overall value of your property.

At Puyallup Spray Foam Insulation, we understand how vital it is to keep your walls insulated the right way. In this guide, we'll walk you through everything you need to know about wall insulation, from its benefits and materials to professional installation tips.

Why Wall Insulation Matters

Walls act as the barrier between your living space and the outdoors. Without proper insulation, you could be losing as much as 35% of your home's energy through the walls. That means your heating and cooling systems work harder, leading to higher energy bills.

Wall insulation is more than just about saving money—it's about creating a living space that feels good year-round. Properly insulated walls help:

  • Improve comfort by keeping rooms warmer in winter and cooler in summer.

  • Reduce energy costs by minimizing heat transfer.

  • Control noise between rooms and from outside sources.

  • Prevent moisture issues like condensation and mold growth.

  • Boost home value by making your property more energy-efficient.

Types of Wall Insulation

There are several materials and methods available when it comes to wall insulation. The right choice depends on your home's design, budget, and energy goals. Here are the most common options:

1. Spray Foam Insulation

Spray foam is one of the most effective options for wall insulation. It expands to fill gaps, cracks, and cavities, creating an airtight seal. This makes it excellent for energy savings and moisture protection. Spray foam comes in two types:

  • Open-cell spray foam: Softer and flexible, ideal for soundproofing.

  • Closed-cell spray foam: Denser and more rigid, providing higher R-value per inch and acting as a vapor barrier.

2. Fiberglass Insulation

Fiberglass batts are one of the most affordable and widely used insulation types. They fit between wall studs and provide good thermal resistance. However, they are not as airtight as spray foam and may allow air leaks if not installed properly.

3. Blown-In Cellulose Insulation

This eco-friendly option uses recycled paper products treated for fire resistance. Cellulose is blown into wall cavities, filling gaps effectively. It's great for retrofitting older homes where removing drywall isn't practical.

4. Rigid Foam Boards

Rigid foam boards can be applied directly to wall surfaces or between studs. They offer excellent thermal resistance and moisture control but may require additional finishing.

Signs Your Walls May Need More Insulation

If you're unsure whether your walls are properly insulated, here are some red flags to look for:

  • Uneven room temperatures (some rooms feel drafty or too hot).

  • Rising energy bills without explanation.

  • Cold walls to the touch in winter or overly warm in summer.

  • Noticeable outside noise inside your home.

  • Moisture issues, like condensation on interior walls.

If these problems sound familiar, it might be time to call in professionals for an insulation evaluation.

Professional vs. DIY Installation

While some homeowners attempt wall insulation as a DIY project, professional installation offers lasting benefits. Insulation isn't just about placing material in the wall cavity—it's about ensuring the right type, thickness, and airtight application.
