Is it time for Cavity Wall Insulation Cost in Carrollton? What is the best type to choose? Let us focus on four specific types. One is blown attic insulation the other is batt insulation. Each type has pros and cons. However, which is the best choice for you.
One of the best advantages of blown attic insulation over batt is that the blown style covers everything; while there can be open areas in the batt type.
When you’re looking to have your home or building insulated with spray foam insulation, you have a couple of product choices. Whether you go with closed foam or open foam insulation, the differences in their make will make a big difference in which one will work best for your needs.
Radiant barrier insulation has one reflective side that is made from an aluminum coating. Any radiant barrier insulation can be installed in an existing or new home. The reflective side of the barrier insulation is made to face the open air pocket of the surface.
Almost all Cavity Wall Insulation Cost in Carrollton are tested and rated as fireproof. If for some strange reason you find one that is not, stay away from that product.
Insulating Walls and Ceilings
Are you considering insulating your home? You might be wondering what type of insulation would be the best fit for you. It is imperative to have the proper amount of insulation in your home. Insulation is rated in terms of thermal resistance often referred to as "R-value", which indicates the resistance to heat flow. The higher the R-value, the greater the effectiveness of the insulator will be. The R-value of the insulation depends on the type of material, its thickness and its density. The three most common types of insulation used in residential or commercial buildings are fiberglass batts, blown cellulose and polyurethane foam.
Fiberglass insulation is made from molten glass and recycled industrial waste. The fiberglass insulation carries an R-value of 3.14 per inch. Although, the fiberglass insulation is cheap there are many deficiencies with the product. Gaps tend to form between each fiberglass batt (known as bypasses) these gaps can become sites of air infiltration or condensation. Each of these deficiencies will reduce the effectiveness of the insulation resulting in a lowered R-value. A vapor barrier must be included in the installation of the fiberglass to prevent condensation and mold form growing. Fiberglass insulation is also hazardous to your health
Blown cellulose insulation is 100% natural and is made from recycled newspapers. The cellulose is treated with a flame retardant and insect repellent to prevent potential fire risks and wildlife infestations. Blown cellulose has an R-value of 3.70 per inch. Unlike fiberglass, Cellulose contains some moisture control characteristics, which prevents the accumulation of condensation and the growth of mold.
Another commonly used insulator in residential homes and commercial buildings is Polyurethane Foam, also referred to as "Spray Foam". The polyurethane foam comes in two different forms, open cell and closed cell. The open cell spray foam insulation is a low-density material. The open cell foam carries an R-Value of 5 to 5.5 per inch. The second type of polyurethane foam available is referred to as "closed-cell foam". Closed-Cell is a high-density foam carrying an R-value of 7.5 per inch. The closed cell foam is dense enough to improve the structural integrity of the building it is applied to. Some advantages of the Spray foam insulation include; air sealing in gaps and penetrations where blown cellulose and fiberglass bats cannot reach, the foam can fill wall cavities in finished walls, it can also act as a sound barrier and can increase the structural integrity of a building as well as provide its own vapor barrier. Spray foam insulation is the most efficient insulating product in the market today.
The History of Spray Foam Insulation
One of the most common deficiencies on a Home Inspection Report is a poorly sealed and insulated attic hatch. You're probably thinking, why should I care about my attic hatch? A home loses about 25% of its heat through the top floor ceiling due to the effect of hot air rising. The attic hatch is a very large opening in that ceiling which accelerates this effect by allowing that rising air to escape the home. If you're lucky this only causes heat loss in the winter and brings attic heat into the home in the summer. If you're unlucky the humid air escaping will condense in the cold attic causing mold and even structural rot.
Installing Latches and Handles (Optional)
Fasten two handles to the inside of the hatch to assist in pulling it down against the weatherstripping. Install four latches on opposing sides of the hatch and trim so that when you pull down on the hatch they secure it against the compressed gasket.
