🏠 SERVICE SPOTLIGHT: Fiberglass Batt Insulation

When people think of insulation, fiberglass batts are often the first thing that comes to mind β€” and for good reason. They're one of the most reliable, cost-effective ways to insulate walls, floors, and ceilings in both new construction and existing homes.

But here's the thing: improper installation is surprisingly common. Gaps, compression, and incorrect R-value choices can all reduce effectiveness significantly.

At Addict Insulation, we make sure fiberglass batt insulation is installed correctly β€” right R-value, right fit, right results. Serving O'Fallon, St. Peters, Wentzville, and all of St. Charles County.

Flat Roof Insulation: What Works Best?
Unlike conventional roofs with large attic spaces, flat roofs have shallow cavities that leave little margin for error. Without proper insulation and air sealing, warm, moist air can become trapped inside the roof assembly, increasing the risk of condensation, reduced energy efficiency, and moisture-related damage.

Flat roofs offer a clean, modern appearance, but they require a different insulation strategy than traditional sloped roofs. Because these roofing systems have limited attic space and less room for ventilation, choosing ...

Got a room above your garage that's always too hot in summer and too cold in winter? You're not imagining things. 😐

Rooms above garages are notoriously hard to keep comfortable. The garage ceiling is often under-insulated (or not insulated at all), which means the floor of that room above takes the full brunt of temperature swings.

In a Missouri summer, that can mean a room that's 10–15Β° hotter than the rest of the house β€” even with the AC running.

The fix is usually simpler than people expect. Proper insulation in the garage ceiling can make a significant difference.

Not sure what's happening up there? We can help.

Is Your Garage Loft Too Hot in Summer & Too Cold in Winter?
If your garage loft feels sweltering during the summer or chilly throughout the winter, inadequate insulation is often to blame. Fortunately, upgrading the insulation can make a big difference in comfort and energy efficiency.

A bonus room above the garage can be one of the most versatile spaces in your home. Whether it's a home office, guest suite, playroom, gym, or media room, a garage loft adds valuable square footage without increasing you...

🏠 Service Spotlight: Blown-In Attic Insulation

If your home feels harder to cool every summer, your attic insulation may be the missing piece.

Blown-in insulation is one of the most effective ways to upgrade an attic β€” it fills in gaps, covers existing insulation that's settled over time, and creates a more complete thermal barrier across the entire attic floor.

🏠 Comfort Starts in the Attic

Is your attic insulation doing enough?

Blown-in insulation provides even coverage across the attic floor, including areas that can be difficult to reach with other types of insulation. Proper insulation helps reduce heat transfer, improve indoor comfort, and make it easier for your heating and cooling system to do its job.

If your existing attic insulation is low, uneven, or has settled over time, it may be time for an upgrade.

If your upstairs feels like a sauna every summer, your AC probably isn't the problem β€” it might be your attic. πŸ₯΅

When attic insulation is thin, missing, or worn out, heat from the roof transfers straight into your living space. No matter how hard your system works, it's fighting a losing battle.

Proper attic insulation keeps that heat barrier intact so your upstairs stays comfortable and your energy bills don't spike.

Sound familiar? Give Addict Insulation a call β€” we've been helping Missouri homeowners solve this exact problem since 2001.
