Fiberglass Insulation – It’s an easy decision

Get the facts about fiberglass

Whether you’re remodeling your home or building a new one, you have a mind-numbing number of decisions to make. With everything you have to think about, what’s going inside your walls – where no one will see – is probably not near the top of your list. But it should be, because you only have one chance to do it right.

With many insulation contractors, you have two options: fiberglass or spray foam. Both have their proponents, but fiberglass has advantages that make it an easy decision.

Breathe easy

The truth is, fiberglass meets high standards for comfort, efficiency and value, and it does so with safe, mineral-based ingredients.

Once you get the facts about fiberglass, you’ll want to have a little chat about it with your builder or contractor.

Fiberglass insulation has known ingredients

Put simply, fiberglass is just another form of glass. Its ingredients – and there are only six of them – are similar to those in the bottles and jars we use every day. They’re just spun into fibers instead of being blown or molded to make containers.
