7 best insulation for basement ceiling

In this article, I will be revealing some of the best insulation for basement ceiling. Most importantly, as a homeowner, you need proper details to make an appropriate choice. The commonly used types of materials for insulation are; fiberglass, spray foam and foam board

The 7 Best Insulation for Basement Ceiling

1. Basement Fiberglass Insulation

Fiberglass is a type of insulation that originates from tiny glass fibers. Moreover, you can install it to insulate walls as well as crawl the spaces. As you complete the installation, there will be a reduction of noise within rooms and external areas.

Pros

  • It improves the overall comfort of building or house for years.
  • Fiberglass installation is part of a DIY project.
  • It enhances the performance of the HVAC equipment.

Cons

  • The holding of condensation creates dampness to cause molds.
  • It releases particles in the air, which are harmful if inhaled.
  • The permeable air batt allows the entry of humid air resulting in moisture and condensation.

2. Basement Spray Foam Insulation

The spray foam usually comes from polyurethane. It best works when applied wet. The substance will later expand to form a thick foam. Indeed, the foam can fit crevices, gaps, and wall cavities.

Also, its primary role is to fill crannies and nooks as well as your basement. Since the spray foam is energy-efficient, you can correctly use it as an air sealing solution. Therefore your basement will stop the outside air from accessing the interiors of the building.

You can best install this type of insulation in hard-to-reach places. It gets better when you perform the insulation around the wiring and piping.

Pros

  • Eliminates mildew or mold growth because it retains no water.
  • Your floorboard will experience fewer drafts since the seal prevents the outside air from accessing the room.
  • The foam boasts of excellent sound absorption properties hence promoting a quiet environment.

Cons

  • The spray foam insulation is costly.
  • When improperly installed, it can cause future discomfort.

3. Basement Foam Board Insulation

You will never go wrong by considering the use of a basement foam insulation. Interestingly, this type of insulation can fit on any part of your house, ranging from the bottom to the top.

Constructed from top-quality materials, the product will serve you for an extended period.

The most commonly used materials are:

  1. Polystyrene
  2. Polyisocyanurate

Pros

  • Consists of tough foams that will resist water to prevent the growth of mildew or molds.
  • Proper installation of the foam board will cause the rigid material to keep off the entry of air.
  • It serves for a long duration without replacement or maintenance, unlike the cellulose and fiberglass.

Cons

  • Inappropriate taping on the joints between the boards and the sheet can cause the air to penetrate your building.
  • The presence of air bubbles within polystyrene may accumulate moisture, reducing its effectiveness.
  • The cutting of the foam board must be perfect. If cut incorrectly, it can lead to air leakage.

4. Cellulose insulation

The cellulose proves to be loose-fill insulation that exists in two main parts; either dry or wet — constructed from a recycled paper primarily from newspapers with other papers or cardboard.

The entire cellulose option is environmentally-friendly since it comes from a recycled source. Furthermore, it undergoes treatment before you use it for insulation. The wet option is always damp when spraying it into the cavity.

Pros

  • It efficiently utilizes the hips of discarded cardboard and paper dumped by paper-oriented society.
  • It is safe as it resists molds and insects. The inclusion of boric acid helps in increasing the level of fire resistance.
  • It’s R-value (R-3.2/inch) is better than that of regular fiberglass, which has R-2.2/inch.
  • They are treated with the acrylic binder to enhance the installation, thereby avoiding future R-value decrease.
  • It has fewer health risks when compared to fiberglass.
  • The cellulose product is ever affordable.

Cons

  • The cost of installation is high.
  • You need a certified breathing mask when installing cellulose as it produces a large junk of dust.
  • The insulation quickly absorbs moisture to compromise the longtime efficiency.
  • It encounters a gradual decrease in R-Value since dry-blown cellulose usually sags and settles.
  • A vapor barrier is a must whenever you use both dry and wet blown.

5. Mineral Wool Insulation

Unlike fiberglass insulation, mineral wool insulation uses natural materials instead of glass. Remarkably, mineral wool exists in two types. Firstly, there is a ball of rock wool that includes fibers of natural stones like diabase of basalt.

The second type is a ball of slag wool with fibers that originate from iron-ore wastes. Traders sell it as loose-fill or as batts. Most of the homes in Europe and North America use this type of insulation.

Pros

  • It naturally resists water while maintaining its insulation qualities even while wet.
  • Blocks sound by a wide margin to reduce acoustic invasion.
  • It resists fire as it can only burn when exposed to temperatures that are beyond 1000 degrees.

Cons

  • Requires protective clothing during the installation process to prevent the inhalation of tiny silvers.
  • The inhaled particles cause alveoli irritation leading to lung complications like cancer and cell mutation.

 

  • The insulated concrete performs poorly in cold climates.
  • Heat may also pass through an insulated concrete.

6. Audimute Sound Absorption Sheet Sound

Typically, blanket batts and rolls come from mineral wool, fiberglass, natural and plastic fibers. It generally lacks facing, but a Kraft paper facing may act as a vapor barrier.

You can use blanket insulation in places like unfinished walls, ceilings, and floors. Its thickness will determine the R-value.

Pros

  • The materials used are readily available and, therefore, cheaper.
  • Easy to install in a house that has less small crevices.
  • It achieves noise reduction from outside and between different rooms.
  • It is energy-efficient if properly installed.

Cons

  • Less durable as compared to other materials.
  • Its R-Value of R-2.9 and R-3.8 per inch in thickness is inappropriate. You may need an additional 10-12 inches of insulation to get correct insulation.

 Best Insulation for Basement Ceiling Buyer Guide

Insulation plays a critical role in the overall comfort of your home. It will absorb the sound and unwanted noise from audio and other devices. Furthermore, it controls the moisture. You should consider the following factors while purchasing your insulation material:

Type of Insulation

Before you select your insulation material, determine where you will be installing it. Each installation type will fit a specific area of your building and provide an excellent service.

For instance, spray foam will work well where the wire or pipe enters the house. Also, a rigid foam board will work best when installed between joists that are above your basement.

R-Value

The R-value of the insulation material will determine the type of task the product will perform. Meanwhile, an R-value of R49 to 60 may suits an attic in some places. One the other hand, R13-R15 can work well on 2 by 4 walls.(Source)

Vapor Barrier

Humid areas transfer moisture along with heat. Whenever the humidity accumulates on the insulation, molds and mildews may appear. In this case, you require the vapor barrier to prevent moisture from condensing in the insulated areas.

Suppose you live in cold climates, you may need a vapor barrier between the insulation and the home’s interior.

Pricing

The quality of the material will affect the price of the product. Some available materials, like recycled paper, prove to be cheap. Next, other insulation types like spray foam may have slightly higher rates.

On best insulation for basement ceiling

In conclusion, Your residence ought to be a comfortable place. You can improve the status by using insulation to absorb sound, prevent moisture, and combat any cold that may come along. Still, you should insulate the basement to seal off the air.
