Installing Home Insulation Cost Texas to your home, attics or outer walls may not be a typical do it yourself weekend project but it certainly can be one that can save time, money and energy costs if done correctly.
Learn how and when it is appropriate to consider expanding foam insulation as a do it yourself project and when you might be better off with a professional doing the installation or even considering other foam insulation alternatives.
Well it need not in fact you may be able to think outside the box as it were and combine systems to come up with a Home Insulation Cost answer that is superior in R value and yet doesn’t bankrupt you.
Obviously, the idea would be to have insulation spray all the way through the house and inside the walls if that were necessary but it is usually very expensive to do that even with the help of kits.
On the other hand, spray foam will fill in nooks and crannies better than any other product and more than one do it yourselfer has chosen to combine extruded Home Insulation Cost and seal the cracks with a polyurethane spray.
This is one of those tricky areas when you and a calculator must sit down and do some hard cost calculations. Expanding foam is superior to almost any other product.
Now, your budget will thank you for the energy savings of an expanding foam attic or even wall insulation but it may not be able to support professional installation or even a full kit to cover your home.
Instead, if the math is unfavorable for using foam insulation in a spray form in all the needed areas, then consider using a less expensive alternative along with the expanding foam. Try saving the foam application for areas where it would be of maximum benefit.
Exterior walls may use rigid polyisocyanurate foam covered with aluminum in order to provide exceptional insulation in Texas and still stay within a reasonable budget.
Spray Foam Insulation Basics
What is Spray Foam Insulation?:
It's a form of insulation, which is sprayed over an area you wish to insulate, instead of the conventional way of placing some sort of insulation in the wall cavity. When it is sprayed it rapidly expands and fills in every single void it can, creating an almost perfectly sealed space.
What are the advantages of using Spray Foam Insulation?:
By expanding and filling ever crack and void it provides complete sealing, preventing air from leaking, which is still in effect with other insulations. It can be placed in any area without having to remove existing tubing, electrical wires or pipes of any kind. It is water repellent and allows moisture to leave from the walls. Mold cannot grow on it. It also prevents the development of mold, which is due to humid air. It is an effective way of reducing outside noises. Also, Spray Foam Insulation has a low flammability. It can be used as an effective way of insulating your boat. It can be used in small areas.
Is it environmentally friendly?:
Many organizations have rated spray foam insulation as one of the greenest methods of insulation with the most attention going to icynene. Most spray foam insulations do not contain HCFC's, CFC's or formaldehyde. They are relatively safe for individuals with respiratory problems such as asthma. So the answer to the question is yes it is environmentally friendly.
Radiant Barrier - The Pro's and Con's
Adding insulation to your attic is a great way to save energy, but there are a number of choices that you need to sort through. What is the best type for your situation? What is the best location for this added insulation? How much should you add?
The first thing that you need to determine is how much insulation you already have. Measure the depth and determine the type. Then multiply the depth by the appropriate value: Cellulose: 3.1, Fiberglass Batt or Blown: 3.7, Closed-Cell Foam: 6.2, Open-Cell Foam: 3.6.
Before you move any further to insulate your attic, you should make sure that you have any knob and tube wiring in your attic that would be covered by insulation replaced. The wires in this type of system need to be in the open air in order to dissipate heat. If they are surrounded by insulation this will trap the heat and cause a fire hazard.
Once you have calculated the R-value of your insulation, you need to determine how much more you should add. Energy Starr has developed recommended levels of attic insulation for every Zone throughout the US. See map at Energy Star and chart below. However, what it boils down to is most houses don't have enough insulation. R-30 is the bare minimum and unless you live in south Florida, the recommended amount is twice that.
Radiant Barriers: work differently than thermal insulation. They reflect the heat away from the thermal insulation, instead of slowing the heat transfer through it. This effectively increases the performance of your thermal insulation in your attic by 50% to 70%. Radiant barriers work best if they are installed between the attic insulation and the roof sheathing, and when they are sloped so that dust will not accumulate on it as quickly. Furthermore, radiant barriers are fairly inexpensive and easy to install.
Your last step is to determine if you are going to add thermal insulation, a radiant barrier, or both. If your house already has what is the code minimum in many locations of R-30, adding a radiant barrier should boost its effectiveness to 45 or even 50. Or if you have an old house with 5 ½" of fiberglass or cellulose (R-17 to R-20) and you add another R-19 and a radiant barrier, you effective insulation value should be between 54 and 65.
