"I like the product so far. It is insulation so I will not know the full effectiveness for awhile. Installation was fine.a little mess, but this a very messy product by nature. My biggest concerns were all related to customer service and communication. Promises to call me tomorrow really meant never. Sales side of the company and the install side did not coordinate effectively..so my install appt had to be rescheduled. When the e-billing came, there was nothing on the invoice allowing me to pay..no address, no phone#, No pay here button, etc. It was just clearly a company living in disorganization. Even the company truck had out of date license plates. I think the product will be good and the value is solid. Just be very clear in your communication expectations if you choose this company."

Insulation questions, answered by experts

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.

An insulated garage benefits from roof vents to ensure proper ventilation and prevent moisture buildup. Insulation can trap moisture in the garage, especially during temperature fluctuations, and roof vents play a crucial role in expelling the moisture in the air. Including roof vents promotes air circulation, preventing condensation and enhancing overall air quality.

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road.
