Insulation Methods

The proper installation methods will result in the maximum performance of the R-value. Homeowners can hire a qualified company such as Pure Eco, to be sure the job is done efficiently and properly. When a homeowner decides to hire a professional certified installer there are 3 key factors you will need to pay attention to:

  • Which method and material you want inside your attic. There is batts, rolls, blown insulation.
  • The materials could be cellulose, fiberglass, denim, and wool insulation.
  • Obtaining a written cost estimate from contractors for the R-Value you need.
  • Ask the Contractor about their air sealing services and cost. This is a good idea because air leaks in the holes you may have in your attic, walls, or crawlspace. Having an installer air seal your home before the installing the insulation is important.

We are going to go over what each method and material that can be serviced in your home to help decide which you would prefer. Some methods and material cost ranges from different price brackets, so be sure to ask the contractor the difference to determine if it fits your budget.

Determining Which Method Works Best For You

The different methods will not necessarily determine the quality of performance, rather it's determined as to preference and where the insulation is installed.

The difference between batts and blown is the structure of the material. One is compacted into a blanket (batts or roll) and the other is loose (blown-in).

To determine which would work best for your home, consider these features:

Batts / Rolls

The Plus Side:

  • Mess free.
  • Fits perfectly in between the joist and wall studs.
  • Some come with vapor barrier (paper to prevent moisture) already attached.
  • No special equipment is necessary for installment.
  • Available in standard, medium, and high density.
  • No need to measure to get right R-Value.
  • Flexible to fit in standard spacing.

The Negative Side:

  • Will not fill in all small gaps of the space, especially if the space shape is irregular.
  • Can only go into easy access areas. Ex: If you want batts in your walls it would either have to be new construction or the whole wall typically needs to come out.

Blown - In

The Plus Side:

  • No easy access requires. For instance this method is preferred for wall insulation. The installer would only need to drill small homes at a certain distance around the home inside or outside to blow in the insulation.
  • Great to use for irregular shaped spaces.
  • Fits between small corners.
  • The job is done quickly and efficiently.
  • Great for low ceilings

The Negative Side:

  • Requires a special machine to install
  • Can be messy
  • Drilling holes is required to do wall insulation

Whichever method you chose, it will still be a great impact to making your home energy efficient and you will still save at least 30% of your energy bill.

Next, we are going to discuss is material batts and blown in come in. The material can also influence the price of insulation. Pure Eco can help assist you to figure out what material will work for your budget as well the preference of the client.


The popular choice among insulation material is fiberglass. People choose this material because it is very cost efficient and still has a strong performance.

Fiberglass, is made up of plastic reinforced by tiny glass fiber. The plastic gives additional strength and improves the insulation capacity.  To create fiberglass, manufacturers use kilns ( a furnace or oven for burning, drying, calcining lime or firing pottery) to melt down the silica and other materials to form a molten glass base. As it cools, it is fed through a system of rollers and extruders to create thin glass fibers. These, after are chopped into pieces and is combined with plastic fill to create what is known as, fiberglass insulation. Fiberglass carries max 50% recycled content.

Methods fiberglass comes in is batts and blown in.

The R- Value fiberglass batts comes in R-11, R-13, R-15, R-21, R-30, and R-38. Blown in Fiberglass as an R-value of R-2.2 to 2.7 per inch. Keep in mind being able to achieve the desired R-value depends on both the depth of the insulation and its density. We will later get into determining R-value.

The downside to fiberglass however is its effect on human skin. Touching fiberglass without protective gear can lead to rash, itch, dermatitis, and remember since there is glass tiny particles can be lodged into the skin. If you do touch it with unprotected gear please do not touch your mouth or eyes, this can lead to irritation. While breathing one must wear a mask when exposed to the fiberglass, this can lead to other health factors that can contribute to the lungs, such as difficulty breathing. Please wear protective gear while handling or being exposed to this material, if you forget to please thoroughly wash your hands before handling anything else.


People’s alternative of fiberglass is usually cellulose. Cellulose is still very cost efficient and provides a great strength of performance.

Cellulose is made up of 75-85% recycled paper fiber, usually from post-consumer waste newspaper and the other 15% is a fire retardant such as boric acid. Cellulose is very ecofriendly and has one of the highest recycled content of any other insulation available. For you eco loving consumers this is an excellent cost efficient way to go!

This material typically comes in forms of batts and blown-in.

The R-value cellulose comes in is 3.5 r value per inch of thickness in blown in and batts its

3.4 - 3.7 per inch.

The downside to cellulose insulation is since cellulose is made of newspaper it can create dust inside the home if it goes through the vents. This may or may not happen.

Soundproof Insulation

Pure Eco uses ROXUL ® as soundproof insulation. This insulation is perfect for customers who love quiet and want to help out the eco system. This product is fairly expensive to other insulation, but well worth it.

ROXUL ® is made up of stone wool, a rock based mineral fiber from basalt rock and recycled slag. Stone wool comes from natural occurrence of byproduct from volcanic activity. This product is by far the number one ecofriendly in the market.

You can find ROXUL ® in batt, board, and pipe forms.

ROXUL r-value depending on the type you get such as cavity rock, comfortbatt, ROXUL safe, and so on can range from 2.5 - 2.6 inches of thickness, and the R-value can be of 4.3 inches and is dual density.

Two downside is that is can be hard to work with, which is why you are having professionals install the insulation, and a faint scent.

The brands that Pure Eco stick too is CertainTeed and ROXUL ® , we find that these brands carry quality insulation, outlasting performance,  and is environmentally friendly, exactly what we stand for.

What Works Hand In Hand with Insulation

There are varieties of services that helps with your insulation. Even though having insulation installed in your home is great, you still want it to have team players. Think of it like this, You have Kobe a star player for the Los Angeles Lakers but even though he is the star player doesn't mean he can play the game alone he needs his team players to help win the game. Same thing goes here the tar player is the insulation but without the help of the other services your savings will only go so far. Check out some of these services to see what you want to play on your team.

Air Seal

Air seal is an amazing accent player for the insulation team. What air seal does is seal up those holes you have throughout your walls, attic, and crawlspace. Sealing up these holes will prevent air from escaping as well as air coming inside. The temperature of the home will maintain the same and your energy bill will decrease because you are using less of the A/C and heater. You are definitely WINNING!

Radiant Barrier

Is great for those hot spring and summer Southern California days. What radiant barrier does is reflects 95% of the sun's radiation rays. What this means is your attic is not getting so hot and you will not have the need to crank up your air conditioner. Keep in mind your attic can reach a high of 130 ℉ degrees, and that due to the sun’s radiation.

A cool attic means a cool home.

Attic Fan for Insulation

An attic fan is also great to help keep the attic cool, remember the motto “a cool attic means a cool home”, this helps supports the idea. What an attic fan does is keep the circulation inside your attic space allowing the air to move around, not stay still, and beats the heat. Think about when you are inside a room and there is just hot still air, and so what you do is turn on your fan to cool down the room, and circulate the air; same concept.

Rodent Proofing for Insulation

You may be wondering how rodent proofing will help with saving energy cost, but trust us it does. Rodents come inside your home one way or another, and so 98% of the time they are not coming in through your front door. What they do is create holes in the attic, crawlspace, and walls to get inside. These holes are allowing air to get inside as well as desired air escaping and now you're wasting the energy bill. Not only that they are contaminating the insulation by making it there bed, and you are breathing inside these contaminants because they are traveling through the vents.
