Attic Insulation – Seal Heat Loss at the Source

Attics are a primary area for energy loss in local homes, and our services focus on creating airtight barriers to reduce cooling costs. With years of experience as contractors, we install solutions that combat humidity and drafts for comprehensive efficiency.

  • Spray Foam Attic Insulation: Our core service—closed-cell or open-cell foam fills gaps with R-3.5–7 per inch, preventing mold in unvented spaces. It's superior for durability compared to blown in alternatives.
  • Blown In Attic Insulation: We use cellulose or fiberglass for fast coverage (R-3–4 per inch), ideal for retrofits. This eco-friendly option complements our spray foam for hybrid setups.
  • Installation Process: We assess, remove old material if needed, and install to R-30–60 per code. We add vapor barriers for humidity control.

Wall & Ceiling Insulation – Enhance Interior Comfort and Sound Control

Our wall and ceiling services strengthen your home's core, blocking noise and temperature swings. We offer installations that improve efficiency while fitting your structure perfectly.

  • Fiberglass Insulation: Reliable batts or rolls (R-3–4 per inch) for walls, providing fire resistance and affordability. We ensure proper fitting to avoid gaps in humid environments.
  • Cellulose Insulation: Dense-packed or blown-in for ceilings (R-3.2–3.8 per inch), offering sustainability and soundproofing. It's a great choice for older homes.
  • Spray Foam for Walls & Ceilings: Delivers rigid seals (R-6–7 per inch) to reduce allergens and AC use. We use it for uneven framing where others fall short.
  • Installation Process: R-13–15 for walls, R-19–30 for ceilings per code. Our pros minimize disruption for seamless results.

Crawl Space & Floor Insulation – Protect Against Ground Moisture

Crawl spaces and floors face local soil moisture, so our services include encapsulation and insulation to prevent rot and inefficiency.

  • Radiant Barrier Insulation: Reflective foil blocks heat (adding effective R-2–5), perfect for under floors. We combine it with spray foam for enhanced protection.
  • Rim Joist Insulation: Spray foam seals floor-wall junctions, stopping drafts in humid conditions.
  • Blown In Insulation for Floors: Cellulose or fiberglass for even fill (R-3–4 per inch), ideal for raised homes.
  • Installation Process: We add vapor barriers and aim for R-10+ to meet codes, ensuring dry, efficient spaces.

Basement/Foundation Insulation – Build a Strong Base

For foundation-focused homes, our insulation services guard against ground chill and floods, supporting efficiency.

  • Spray Foam Foundation Insulation: Closed-cell bonds to concrete (R-5–7 per inch), adding waterproofing and strength.
  • Fiberglass or Rigid Foam Boards: Durable boards for exteriors (R-5 per inch), resistant to soil shifts.
  • Cellulose Alternatives: Used in interiors for eco-friendly fills.
  • Installation Process: R-10 for slabs; we prioritize drainage in flood areas.
Insulation Comparison

Pros, Cons & Best Uses of Popular Insulation Types

Every building is different. That is why Phantom Foam customizes recommendations based on the structure, moisture exposure, budget, and performance goals—so you get the right insulation system for the job.

Spray Foam Insulation

R-3.5–7 / inch

Best for: Attics, walls, hard-to-seal areas, and high-performance building envelopes.

Pros

  • Airtight seal helps reduce air leakage
  • Available in open-cell and closed-cell options
  • Closed-cell adds moisture resistance and structural strength
  • High performance in demanding Houston-area conditions

Cons

  • Professional installation is required
  • Higher upfront cost than some traditional materials
Phantom Foam’s top recommendation in many applications because it can air seal and insulate at the same time.

Blown-In Insulation

R-3–4 / inch

Best for: Attics, retrofits, and filling existing cavities quickly.

Pros

  • Quick to install in many attic applications
  • Can help fill irregular gaps and hard-to-reach areas
  • Available in fiberglass or cellulose forms
  • Good option for upgrade projects and retrofits

Cons

  • Can settle over time
  • Some materials can absorb moisture if conditions are poor
  • Does not create the same air seal as spray foam
A solid choice when budget and speed matter, especially in attic top-offs or upgrade work.

Fiberglass Insulation

R-3–4 / inch

Best for: Walls, ceilings, and budget-focused insulation projects.

Pros

  • Affordable and widely available
  • Fire-resistant material
  • Common solution for standard wall and ceiling cavities

Cons

  • Can leave gaps if not installed perfectly
  • Not an air barrier
  • Can underperform in humid environments if the assembly is poor
Often chosen for value-driven projects, but performance depends heavily on installation quality.

Cellulose Insulation

R-3.2–3.8 / inch

Best for: Energy-conscious builds and projects that value sound control.

Pros

  • More sustainable material option
  • Good sound dampening qualities
  • Can work well in dense-pack or blown applications

Cons

  • Needs proper dry installation conditions
  • Moisture management is important
  • Not the same air-sealing system as spray foam
A good fit where sustainability and acoustic control matter alongside thermal performance.

Radiant Barrier Insulation

Reflective System

Best for: Attics and hot roof assemblies where reducing radiant heat gain matters.

Pros

  • Reflects radiant heat rather than absorbing it
  • Can improve hot-weather attic performance
  • Works well as part of a larger insulation strategy

Cons

  • Does not replace bulk insulation
  • Requires correct installation and air space to perform well
  • Best when paired with other insulation types
Best viewed as a supporting layer—not a standalone answer for full thermal performance.

Our take: Spray foam is often the strongest all-around solution for performance, air sealing, and long-term efficiency—but in many projects, a hybrid insulation system delivers the best mix of value, comfort, and durability.

Home Insulation FAQs

Answering Your Home Insulation Questions

Homeowners ask a lot of smart questions before insulating a house—and they should. Here are some of the most common questions we hear about humidity, installation, insulation types, and long-term performance.

01

What’s the best option for humidity control?

Spray foam—especially closed-cell—is one of the strongest options for controlling moisture and air movement. It helps create a tighter building envelope, which can reduce the risk of mold and long-term moisture problems better than traditional fiberglass.

02

How does installation work?

We begin by evaluating the home and identifying the right insulation strategy for the space. From there, most projects move into installation and completion within about 1 to 3 days, depending on size and scope. We also work to keep disruption minimal and make sure the work aligns with code requirements.

03

Is blown-in better than fiberglass?

It depends on the application. Blown-in insulation can do a better job filling irregular spaces in retrofit situations, while fiberglass is often simpler and more budget-friendly. In some homes, a hybrid approach creates the best overall efficiency and value.

04

What are the benefits of radiant barriers?

Radiant barriers help reflect heat away from the home, which can reduce attic heat buildup and lower cooling demand. They perform especially well when paired with spray foam or another complete insulation system in hot climates.

05

Can you handle foundation work?

Yes. Phantom Foam can help with more than just attics and walls. We also handle foundation-related foam solutions and other projects where a full-building approach makes more sense than a single service.

06

What’s the difference between cellulose and blown-in fiberglass?

Cellulose is often chosen for its recycled content and sound-dampening qualities, while blown-in fiberglass is typically a more affordable option. The right choice depends on the goals of the project, the assembly, and how the space needs to perform over time.

07

How can you help with rebates?

We help homeowners understand available rebate opportunities and how their insulation project may qualify. That includes guidance on local utility programs and helping you maximize the savings available for your upgrade.

08

Is spray foam the best option for walls?

In many cases, yes. Spray foam is one of the best wall insulation options because it provides continuous coverage, helps seal air leaks, and delivers stronger overall performance than materials that can leave gaps behind.

Still have questions? Every home is different, and the right insulation strategy depends on your structure, goals, and budget. Phantom Foam helps homeowners choose the best fit— not just the most common option.
