What is the usage of Blanket insulation?

R1.3 Extra Heavy Duty Blanket InsulationThe widest types of insulation used in the building are Blanket insulation. It is widely available and is available in the form of rolls or batts. Most commonly fiberglass which is flexible fiber is used. Rolls and Batts can also manufacture by plastic fibers, mineral (slag and rock), natural fibers like sheep’s wool and cotton.

Use and Application of Blanket insulation:

  • Rolls and Batts come in widths to the standardized spacing of rafters or attic trusses, floor joists and wall studs: 2-inch x 4-inch walls can withstand about R-13 or R-15 batts; 2-inch x 6-inch walls may resist or use R-19 or R-21 products.
  • For a vapor barrier, manufacturers often attach facing like vinyl, kraft paper, and foil-kraft paper to act as an air barrier. Continuous rolls trimmed or hand-cut to fit.
  • Places where insulation tends to be left exposed and for basement widths, Batts are used with specialized flame-resistant facing.
  • Fastening also facilitated by facing during installation.
  • Blanket insulation installed between beams, studs, and
  • This type of insulation can use in the ceilings and floors and unfinished walls.
  • Ductwork and pipes wrapped with Blanket insulation.
  • Retrofitted in the attic over existing insulation

Types of Blanket insulation:

Blanket insulation is often available in two types of forms:

  1. Rolls: Rolls are recommended to use in buildings or houses with varying space size and great wall dimensions. One of the main reasons, rolls are used is because they can be hand-cut or trimmed in any required format. Rolls are uncut versions of the batt. Rolls can be used around steel studs or joists as a type of Blanket insulation.

 

  1. Batts: Batts tends to be pre-cut to precise dimensions, which makes them different and the only difference between rolls and batts. Batts can fit into walls with measuring cavities of 92 5/8”. Pre-cut batts are perfect to use if you are working with these dimensions.

Benefits of Blanket insulation:

Considering the wide availability and usability of Blanket insulation, the benefits of Blanket insulation are countless. Mostly fiberglass is used in this type of insulation which consists of small fibers. This type is typically used without many obstructions in spaces like pipes and wiring etc. and unfinished walls inclusive of foundation walls, floors and ceilings are in. Blanket insulation can be fitted between beams, joists, and steel studs. The benefits or Blanket insulation are:

  • The energy bill decreased
  • All year long, home can be kept comfortable by maintaining a favorable temperature at all times
  • Noise reduction from outside and between the floors and different rooms
  • HVAC systems’ efficiency improved with this type of insulation
  • Cost-effective and pocket-friendly
  • Provides Radiant barrier in the ceiling when used to assist reflect heat from the roof instead absorbing the heat from the direct exposure of sun
  • Most recommended in warmer climates
  • Can be used commercially due to wide availability and low cost.
  • Can be hand-cut or trimmed to required size to fit in an area.
  • Can fill small to larger spaces and uneven dimensions

R-Value of Blanket insulation:

The thickness of Blanket insulation determines the R-value of fiberglass Blanket insulation. It consists of about R-2.9 to R-3.8 per inch of thickness. If high-performance blanket fiberglass insulation used, it comprises R-value between R-3.7 to R-4.3 per inch of thickness.

To get a brief knowledge in determining R-value that fits your standardized climatic variants, an insulation professional must be contacted because R-value can at times become a bit difficult to understand.

Installation:

The better option for the installation of Blanket insulation is through insulation installer because R-value or Maximum Thermal Performance dramatically depends upon proper installation of the insulation. If you are opting to get it done professionally either by yourself or someone else, these measures must be kept in mind always:

  • Obtain the cost estimation of your required R-value in a written form from several contractors. There may not be much fluctuation in the quoted prices for a certain R-value installation, don’t be surprised.
  • Do go through the market for costs and air-sealing services, if not, ask the contractors if needed.

Cost:

Widely available and often used due to excellent resiliency, acoustic absorption, thermal performance, cost-effective, pocket-friendly and low price.
