Things to Know Before You Insulate Your Attic.

The Attic insulation is one part of the home that we tend to forget about. More often than not, we turn it into a store of some sort or just leave it dusty and abandoned.
Truth is that the little space up there between your roof and your ceiling controls most of the air flow that comes into your home and requires extra attention for it to serve its full purpose.

As the seasons change from summer to winter, we are bound to experience a change intemperature and the need to maintain a comfortable indoor climate increases .While our heating and cooling energy systems can help regulate in-house climate, insulating the attic can go a long way in creating that cozy living atmosphere in our homes.

Attic insulation might sound like a difficult college science project, but with moderate technical know-how, it is a relative do-it-yourself process that you can achieve on your own.
Whether you are doing a major home renovation or just getting prepared for the cold winter, attic insulation comes with great benefits for that warm comfort you desire for yourself and your family.
There are many qualified building contractors willing to help you get the work done at the right fee, but if you are looking to save cost, then there is no harm in getting your hands dirty up there.

Why you need your attic insulated

Most people don’t even take a peek into their attic not until problematic issues begin to develop up there. It is important to observe simple attic sanitization and even better to ensure it is insulated.

Here are some important reasons to insulate your attic:
  1.  To Avoid Rodent Infestation.

    Where do you think most rodents go to hide when they disappear through those little holes they have scratched out in your home? If they are not hidden somewhere in your closet or the underground space, they are most likely in your attic.
    Insulating your attic, which demands cleaning it out first, helps you seal up holes and gaps used as getaway channels by rodents in your attic.

  2.  Prevent Leaking Air

    A properly insulated attic will see to the sealing up every opening, gap, hole or crack. What does this entail? Heating air or cool air will no longer escape through your attic, thereby keeping your home at the desired temperature.

  3. Save Cost on Energy.

    Insulating your attic will make your home more energy efficient. Installing the right insulation will deliver long-term cost savings from season to season. According to statistics, this can amount up to 10-50% saved costs on energy use.

  4. Better indoor air quality

    Attic insulation blocks air leaks that allow dirt, dust, mold, mildew and other pollutants to enter your home, allowing you and your family to breathe easily and enjoy a clean, fresh indoor air.

  5.  Stronger Building

    Insulating your attic helps to sustain your home and prevent degradation caused by heat and moisture. It also prevents water from entering and messing up your walls while also reducing the effects of condensation on your roof.

  6. Reduces HVAC Degradation

    Proper attic insulation regulates the flow of cool air from at the lower levels while there is a rise in temperature by preventing it from lingering. This helps in reducing the level of wear and tear on the HVAC unit of the home. With the insulation in place, you and your family will rely less on the home’s heating and cooling systems as heat is gained during summer and lost during winter giving you a comfortable indoor temperature as the seasons change.

When Insulating Your Attic.

The first thing to consider when you are about to insulate your attic is the type of insulation you want for your home, what type of materials you will use and the cost implication of this.
Three major types of insulation materials are appropriate for the attic – fiberglass, cellulose and mineral wool. However, you have to, first of all, decide what type of insulation is best for your home.
For lack or professional know-how, it’s best not to decide on an extra technical insulation type. Therefore, for DIYs, you have to choose between loose fill and blanket insulation (commonly known as batt).
When making the decision over what type of insulation to use, also consider the price of the materials required. Have it at the back of your mind that the target is to save cost while also etting the best of our energy needs.

Taking all these issues to worry about from you, you can consult on Attic Insulation professionals in your area. At Air Quality Express, you can be rest assured everything would be well taken care. You can call on us for your Attic Insulation in Texas.  832-781-0105

Loose Fill

Having a loose fill attic insulation demands packaging insulation fibers in bags and blowing it in place to achieve the required depth.
Loose fill is most suitable for attics with existing insulation. It fills gaps, openings, and joints perfectly. It is also fit for attics that has lots of construction obstructions which will hamper easy penetration.
If your attic has a low headroom or an irregular spacing, the loose fill also works best. It saves you the discomfort of struggling to maneuver your way around the attic while insulating it.

Materials & R-Value   

For your loose fill, you will need:
• Fiberglass with R-Value of 2.2 – 2.7
o Settles better than cellulose and mineral wool but because it is lighter, more
is needed for the attic insulation.
• Wool (Mineral) with R-Value of 3 – 3.3
o It is more expensive than other materials but offers the value of natural fire
resistance being made from rock fibers or recycled slag.
• Cellulose with R-Value of 3.2 – 3.8
o You will find out that there are more people, including professionals, who use

cellulose for loose fill because it is pest-treated and resistant to fire.
Blanket Insulation Batts, as Blanket Insulation, is commonly called works best for attics with regular joists with no prior insulation. It is also perfect for attics with fewer obstructions and a headroom sufficient enough not to impede the flow of the installation process.
The insulation material is usually a flexible roll with a width measurement that ranges between 16 inches to 24 inches fit for a perfect house framing. It usually has a paper or foil layer that acts as a blocker for vapor. To achieve the desired insulation level, varied layers of the roll is added during the installation process.

Materials and R-Value    

Attic insulation Houston

• Fiberglass – R-Value per inch: 2.9 – 4.3
o It is more cost effective and widely used despite it being less potent in
preventing airflows.
• Mineral Wool – R-Value per inch: 3 – 3.3
o Much more expensive than other batt materials but highly effective in
withstanding fire outbreak.
• Cellulose – R-Value per inch: 3.7 – 3.8
o Not very common in the market but causes less irritation when being used for insulation.
• Cotton – R-Value per inch: 3.7 – 3.8
o Effective in blocking airflows and noise from unwanted sound but highly
expensive as it is made from recycled denim materials.

What is R-Value?

Insulation is identified and measured by R-Value, where ‘R’ refers to resistance to heat flow.
What this means is that the higher the R-Value of your insulation, the greater the insulating
power. When buying products for your insulation, you will find the R-values labeled on the

How Much is Required?

Depending on the square meter of the space in your attic, the average spend you should
budget for your insulation should be about $500 to $1,000 for materials.
Since it is a DIY, you will need to hire some equipment which is far more economical than
buying. Equipment rental should cost somewhere about $80 to $100.
That means that a total budget of $800 – $1,500 is enough to get all you need for your attic

Tips for Attic Insulation

• Seal all gaps, holes, cracks, openings and air leaks before beginning the insulation process.
• Make sure to check for any leaks in the roof and seal it up before insulation. This will guard against having water drip into your insulated attic as water and insulation are enemies.
• Do not allow your insulation material to come in contact with any recessed cans or lights on the floor to avoid future fire outbreak. Hardware clothing or plywood
applied 3 inches around all light surfaces and/or cans.
• For unfinished attics, insulate the attic floors only as the goal is to keep the rooms below cool in summer and warm in winter.

• For finished attics, insulation must include the walls and the ceiling much like the rest of the house.

• Wear a dust mask to protect yourself when installing insulation in your attic.
• Avoid standing on the joists during the process so you don’t crash through the ceiling.
• Wear a long-sleeve shirt, long pants, goggles, and gloves to further protect yourself from dust and fibers.
• If there are exhaust fans in your attic, direct them to the exterior to prevent humid air from ruining your insulation.
• If there was no prior insulation, ensure that your vapor barriers are in the right place when insulating.
• Ensure to install insulation on the attic walls and ceiling.
• Work from the area towards the door so you don’t soil and walk all over your insulation when done.
• Have a long thorough shower when done to remove fibers from your body.
