"We were considering upgrading our insulation but weren't sure if it was worth the investment. After consulting with Lake Atitlan Insulation, they convinced me it was the right choice. The insulation they installed not only made our home more comfortable but has already saved us money on energy costs."

"The entire process from estimating (Kenny) to project management (Walter) to team members (four), was efficient, respectful of our property and extremely communicative. The team went multiple extra steps to make sure our crawl space free of entry points for critters while installing all new insulation"

"They sprayed the ceilings of my cargo containers and it worked perfectly. They're warmer in the cold and cooler in the heat. They were prompt, professional and they cleaned up afterwards. It was expensive, but well worth the money compared to me building frame walls and installing batts of insulation and covering with plastic, etc. Their insulation dries hard and even after months, it hasn't been damaged. I'm really picky about good quality work and they checked every box."

"Acorns Attic was hired for a rodent removal job and I had some insulation replaced since it was dirtied with rodent droppings. Phil and team did a great job. They took plenty of pictures of before and after. I haven’t had rodents since they patched up the openings and the insulation looks great!"

Insulation questions, answered by experts

Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.

The cost of installing spray foam insulation is $2,760 on average, but this cost can be as low as $650 or as high as $7,700. The main cost factor is the size of the insulated area and the type of spray foam insulation. 

Polyurethane spray foam costs between $0.44 and $1.50 per board foot, where a board foot is equal to the volume of a one-foot length of a board. More expensive options, like soybean or vegetable oil spray foam, range from $1.50 to $3.00 per board foot.

Generally, the cost of ice dam removal is not covered by homeowners insurance because it is often considered preventable maintenance. However, the damage caused by ice dams is frequently covered. Depending on your policy, this can include interior water damage, roof collapses, and damage to shingles. Coverage for personal belongings affected by leaks may vary. It is important to check your policy details or contact your insurer to confirm what your plan covers. Keep in mind that any damage resulting from a DIY attempt to remove an ice dam will likely not be covered.

The thickness of floor insulation will depend on the R-value you plan to achieve. R-value varies on the type of material as well as its thickness and density. Insulation materials with low R-values can be layered to match the value of denser materials. As long as your floor insulation is packed tightly, seals the area from drafts, and doesn’t prevent ventilation, it can be as thick (or thin) as you need.

No, 55 degrees Fahrenheit is not too cold for a house, as it’s a temperature that will keep your pipes and appliances from freezing. Well-insulated homes can even go to 50 degrees, but check with an HVAC pro before opting for such a low temperature. Stick to 55 degrees to be on the safe side.
