Buying attic insulation has many potential benefits. You get to save on energy costs all the while being comfortable in your home. As such, the buying process should be taken with all the seriousness it deserves. You should have a comparison table highlighting the pros and cons of each option you have.
Things to keep in mind while choosing insulation for attic
Here are some critical considerations.
Climate
This is, of course, the climate around your residential area. Is it cold all year round or does the weather change often? If cold is the prominent factor, you might need one-sided insulation which retains the heat in your house. If heat is what you experience the most you can use a double reflective surface like the RadiantGUARD Ultima Radiant Barrier where heat inside the home doesn’t dissipate and heat outside the house doesn’t directly affect temperatures inside the building.
Attic size
The products mentioned above come in different sizes, and so do attics. If you are unaware of your attic size in terms of square footage, you might buy something too small or too bulky for your needs. This would either cost you a trip back to the store or leave you with excess insulation. To avoid this, take some time to measure the various dimensions of your attic.
Safety of insulation material
Is it fiberglass or aluminum film? Do you have to spray it? What safety gear do you need to handle the insulation? Answering these questions will ensure you don’t need to make a trip to the doctor’s office later on. Generally, insulation materials made of aluminum and metalized film tend to be safer and easier to handle. Those with fiberglass components with examples such as the JOHNS MANVILLE INTL Kraft-Faced Roll need you to take some precautions before you handle them.
Also, there are those that require the use of a sprayer like the LO/MIT-II MAX Attic Heat Barrier. It is imperative that you don’t breathe them in. They might cause or aggravate existing health issues. Also, you can opt to engage the services of a professional if need be.
Prices
The prices are also different with each product we have mentioned. It is essential that you buy one within your budget range. However, there is often a notable difference between products with high pricing and those with low pricing in terms of quality.
