Quality Insulation Materials for Chicago Homes

There are several types of insulating materials for new or existing residential insulation. Which material(s) we recommend depends on several variables.

We consider square footage, your home’s building materials and the size of your space that needs insulating. Whether you’re building a new home or retrofitting to lower energy bills, we have the insulation solution that works for you:

  • Cellulose: Cellulose is a sustainable option, made from 85% recycled materials. It’s the choice for many energy-conscious homeowners and is available as loose-fill (dry) and spray-applied (wet).
  • Fiberglass: Fiberglass continues to be the most affordable and environmentally friendly insulation. It’s available as blown-in insulation or batts.
  • Radiant barrier: This material reflects heat rather than absorbing it. In Chicagoland, it’s sometimes paired with another insulation material.
  • Spray foam: Spray foam is a popular choice. It fills spaces other insulations can’t reach.

Your Chicago-area home HVAC accounts for as much as 42% of your monthly utility expenses. Without good insulation, you’re paying more than necessary.

Northern Illinois homeowners trust ThermaSeal/Lakeside Insulation for experienced, affordable insulation solutions.

Frequently Asked Questions

How Does Insulation Work?

Insulation works by resisting heat flow, which increases your home’s energy efficiency and helps reduce your monthly bills. How it stops heat transfer depends on the type of insulation – for instance, radiant barrier, which is installed in attics, reflects the energy from the sun, while fiberglass traps warm air.

What Is R-Value?

If you’ve ever talked to an insulation contractor, you’ve undoubtedly heard the term “R-value.” Basically, the R-value of a certain type of insulation refers to how effective it is at stopping heat transfer.

The R-value depends on the material, thickness and density of the insulation, and of course, installation (improperly installed insulation is almost like having no insulation at all!).
