"Did not do work, but pricing was competitive with everyone else.  Invoice got lost in junk e-mail, so did not think I ever received invoice, but I found it a month or so after job was completed again.  If\when I have another job will call All Foam and make sure Invoice doesn't get lost in junk e-mail!

Insulation questions, answered by experts

Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.

The heat loss through a poorly insulated attic when you’re running your furnace or heat pump during cold weather can be as high as 25%. This means you could see significantly higher energy costs to make up for this heat loss. The cost of adding insulation to the attic may eventually pay for itself through lower energy bills. If you decide to add a radiant barrier too, the radiant barrier cost may also pay for itself over time.

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.

While fiberglass is dangerous to work with, it’s a perfectly safe material once it’s installed. If you’re tackling the installation yourself, make sure you take the proper safety precautions and wear the right gear to avoid skin and eye irritation and lung complications. Working with a professional insulation company can mitigate these risks.

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.
