Many people don’t know if their old houses can ever be converted to become more energy efficient. Of course they can. And retrofit insulation as an energy conservation measure has brought older constructions much improvement and change that complies with new regulatory standards. Buildings constructed 30 years or more earlier are wasteful of energy. The very concept of energy efficiency was unheard of in those times. And folks wanted to live in huge houses and drive big vehicles that were gas guzzlers. Not any more. Today, most people care about pollution and want to conserve scarce resources.
No longer is it possible to brush aside the warning signs of a planet at risk. Climate change
and global warming are affecting every day events. Unless we change how we consume energy and cut down on carbon emission, our children and grandchildren will certainly pay a stiff price for our carelessness. That’s why newer buildings must focus on cutting down carbon emission and using energy more efficiently to minimize waste and reduce pollution.
The law also requires that older buildings become more energy compliant by taking up retrofit insulation. It’s easy to insulate buildings as they are being constructed as the insulation can be placed in the empty spaces in the wall. It is a little difficult to put in the insulation in older buildings as you have to pull apart the structure to put in the insulating material.
Certain types of insulation do not need for the walls to be pulled apart. Take for instance spray foam insulation that is sprayed into the wall cavities though small holes drilled at the bottom of the walls. Once sprayed into the empty spaces it expands and fills the whole are and the holes are sealed. Blown in insulation and spray foam insulation are the two types of such insulation in use for retrofitting old structures.
For retrofit attic insulation that uses materials like cellulose or fiberglass the material is blown in both from bottom and top. For some types of insulation a little water is used to help the insulation to stick to the walls. When moisture is used it is important to let the insulation to dry completely before sealing it off. Moisture in the insulation defeats the very purpose as it can completely negate the insulating properties of the materials.
