Spray foam insulation for Renaissance Park Residents

Spray Foam Insulation

Here’s the thing about most new construction in the Raleigh area—builders insulate to code, not to comfort. Code is a minimum standard. It means the house passed inspection, not that your insulation is actually doing a great job. Most Renaissance Park homes have standard fiberglass batts in the walls and blown-in insulation on the attic floor. That’s fine on paper, but in practice there are gaps everywhere.

Spray foam insulation is a completely different approach. It goes on as a liquid, expands to fill every crack and cavity, and hardens into a seamless air barrier. No gaps around electrical boxes. No spaces where pipes come through. No weak spots where batts were cut a little too short and don’t quite reach the framing.

We use two types in Renaissance Park homes:

• Open-cell spray foam: Lighter, flexible, and excellent for attics. It has strong air-sealing properties and helps dampen sound between floors—something Renaissance Park homeowners with two-story homes really appreciate.
• Closed-cell spray foam: Denser, higher R-value per inch, and it doubles as a vapor barrier. We use this in crawl spaces, rim joists, and exterior walls—anywhere moisture control matters. Raleigh humidity is brutal, and closed-cell keeps it out of your wall cavities.

The U.S. Department of Energy estimates that sealing air leaks can save homeowners 15–25% on heating and cooling costs. In a neighborhood like Renaissance Park where homes are already reasonably efficient, spray foam takes you from “good enough” to genuinely comfortable.

Insulation Installation

Our insulation installation process is built around actually understanding your home before we touch anything. We start with a detailed walkthrough—attic, crawl space, garage walls, rim joists, bonus rooms. We look at what the builder put in, how its holding up, and where the weak spots are.

For Renaissance Park homes, here’s how a typical project goes:

• Home inspection: We identify problem areas—thin insulation spots, unsealed penetrations, ductwork issues, and moisture concerns. Renaissance Park homes have a fairly consistent layout, so we know the common trouble spots.
• Protection and prep: We cover floors, mask off mechanicals, and prep the surfaces. If existing insulation needs to come out first, we handle that as part of the job.
• Spray foam application: Our crew applies the foam in layers, letting each pass expand and cure properly. We control thickness carefully—this isn’t a rush job. Most Renaissance Park attics take about half a day.
• Walk-through and cleanup: We show you what we did, clean up everything, and make sure your satisfied before we leave. You should feel a difference in your home within the first day or two.

Insulation Removal

Even in a newer neighborhood like Renaissance Park, insulation removal is sometimes necessary. We’ve seen blown-in insulation thats settled unevenly, leaving thin spots and bare areas. We’ve found fiberglass batts that were installed backwards—with the vapor barrier facing the wrong direction—which actually traps moisture instead of blocking it.

We’ve also been called into Renaissance Park homes where a roof leak or plumbing issue damaged the existing insulation. Wet insulation looses almost all of its R-value and becomes a mold risk. It needs to come out.

Our insulation removal process is clean and controlled. We use commercial vacuum equipment and containment to keep debris out of your living space. Once the old material is out, we can inspect the framing, identify hidden air leaks, and install spray foam with a clean starting surface.

Energy Audit

A lot of Renaissance Park homeowners call us saying something like “my house is only ten years old, why are my bills so high?” That’s a fair question, and an energy audit gives you the answer. We bring in thermal imaging cameras and scan your home from the inside. The camera shows heat movement in real time—bright spots where conditioned air is escaping, cool spots where outside air is getting in.

We also run a blower door test to measure your home’s overall air tightness. This gives us an actual number—not a guess—of how leaky your house is. For Renaissance Park homes, the results usually show that the house is performing below where it should be, even though it looks great from the outside.

Common problem areas we find in Renaissance Park energy audits: attic bypasses around recessed lights and plumbing vents, poorly sealed rim joists in the crawl space, and gaps around HVAC register boots. These are all things spray foam fixes permanantly.

Attic Insulation

The attic is still the biggest energy problem in most Renaissance Park homes, even newer ones. Standard construction puts insulation on the attic floor and vents the attic space to the outside. That means your HVAC ducts, which run through the attic, are sitting in unconditioned air that can reach 140 degrees in a Raleigh summer.

Your air conditioner pushes cooled air through those hot ducts, and by the time it reaches your upstairs vents, it’s already warmed up several degrees. Your system runs longer, uses more electricity, and still can’t quite get the upstairs comfortable. Sound familiar?

Spray foam attic insulation on the roof deck brings the attic inside your home’s thermal envelope. The attic stays close to indoor temperature year-round. Your ducts work efficiently because they’re no longer fighting extreme heat or cold. Renaissance Park homeowners who’ve done this upgrade consistently tell us their upstairs rooms are finally the same temperature as the rest of the house.

Why Renaissance Park Residents Choose LiveGreen

We’re a local Raleigh company—not a national franchise. Our crew lives and works in the Triangle, and we’ve done spray foam projects in Renaissance Park, Walnut Creek, Barwell Road area, Lake Wheeler, Tryon Hills, and across south Raleigh. We know the construction styles, the builder shortcuts, and the specific challenges that come with Raleigh’s climate.

We’re also realistic about cost. Spray foam is more expensive then fiberglass—there’s no getting around that. But for Renaissance Park homes, the return on investment is strong because you’re already starting with a relatively tight house. Spray foam closes the remaining gaps and takes your energy performance from average to excellent. Most homeowners see payback in 3–5 years through lower energy bills, and the comfort improvement is immediate.
