Need New Insulation? Know The Essential Information About Spray Foam

Construction & Contractors Blog

If the energy efficiency of your house is suffering, you could benefit from upgrading your home's insulation. While you may be tempted to use traditional materials like fiberglass, spray foam insulation is a viable alternative to keep the cold from seeping in through your attic's walls. Here is some essential information about the material.

Pros and Cons of Spray Foam

Many homeowners like using spray foam because the material expands. The shape that the foam creates forms well around cracks of all shapes and sizes. It works best with surfaces that are not even, like pipes and joints, creating an insulation barrier that is much better than a fiberglass insulation blanket. It will be much more effective at sealing all the small areas where cold air gets inside your home.

The biggest disadvantage of spray foam is how it is difficult to install. If you have never installed spray foam before, it will be difficult to anticipate how much the material expands. If you are spraying foam inside a wall, spraying too much can damage the wall when the insulation expands. Not only will you have to pay for the repairs to the wall, but it will also cost you money by installing more insulation than you need. You will need to cut off the excess insulation as well, which is time consuming.

There Are Many Kinds of Spray Foam

There are different variations of this kind of insulation that work best for almost any situation. For example, small gaps in an attic are best filled on your own using a handheld can of foam. Larger surfaces, like a ceiling or wall, can be insulated using a handheld wand. Insulating a whole home requires more foam than what will fit in a canister, which is when a professional comes in handy to install it for you.

When it comes to the insulation itself, there are two forms to pick from: open and closed cell insulation. Open cell foam works better for walls on the interior of your home, since it is cheaper and does not contain a moisture barrier. Closed cell foam will repel moisture, which will make it the best option for exterior walls and attics. Closed cell foam will cost more money though.

Custom Kitchen Creation: What You Should Know Before Getting Started

When I decided that I wanted to go to culinary school, I knew that I wanted to be able to really practice what I was learning at home. As I stepped back and looked at my home kitchen, it really needed help. I talked with a local remodeling contractor about how we could create a more comprehensive and functional kitchen. The process included taking out a wall, expanding the kitchen footprint and upgrading all of the appliances. I created this site once it was done to share my story and tell others about the things that you can do to make your kitchen really feel like your own.
