Insulation is anything that blocks the movement of heat. Heat flows when molecules with more energy (more heat) bump into molecules with less energy (a colder place has a low movement of the molecules). We have a lot of ways to control this movement, and insulation is the building process that can do that. The simplest way to block heat conduction is the creation of an empty zone that has no matter. Unfortunately it is not possible to create vacuum in your walls. Because of that we have to install some material that will help our goals to block the heat exchange.
The following are the most common types of materials used for insulation
- Batt insulation
- Fiberglass batts and blankets
- Rockwool Batts and Blankets
- Structural Insulated Panels (SIPs)
- Polystyrene SIPs
- Polyisocyanurate SIPs
- Loose-Fill Insulation
- Loose-Fill Fiberglass
- Loose-Fill Cellulose
- Spray foam
- Open-Cell Polyurethane Spray Foam
- Closed-Cell Polyurethane Spray Foam
Take a look at your electric, gas, or oil bills from past years. Thousands of dollars are wasted every single year because homes are not weatherized to today’s building standards.
Properly air sealing and insulating is the most cost-effective home improvement you can make today. Our state has has the Mass Save program, and you and your home energy specialist can determine the most economic solutions. If your house is an old one consider changing the HVAC system if you are planing a renovation. Heat Pumps are among the best in class to help you if your goal is to decrease your bills.
