10 Types of Insulation for Every Home 2023

As a homeowner, you are aware of how important insulation is to the operation, comfort, and energy efficiency of your home. Thermal Insulation done properly can help keep temperatures stable, lower energy costs, and improve living conditions. However, different types of insulation materials are made uniquely for multiple purposes that are available to insulate your home.

The thermal insulation market in India achieved a valuation of INR 3,674.98 crore in 2020 and is anticipated to reach INR 2,189.81 crore by 2028. This represents a projected growth rate of 7.4% from 2021 to 2028. The significant expansion and development of India’s infrastructure are emerging as vital factors in the fight against climate change.

This blog will discuss 10 types of thermal insulation that every homeowner should be aware of.

What is Insulation?

Buildings may employ insulation as a material or construction method to reduce the flow of electricity, heat, and sound between the interior and outside environments. Its major objective is to provide a barrier that restricts the flow of thermal energy, keeping the interior temperature steady, increasing energy effectiveness, and enhancing comfort.

what is insulation

In order to slow down the flow of heat, materials with poor thermal conductivity, such as fiberglass, foam, or cellulose, are put in walls, ceilings, floors, and roofs. This ultimately lowers heating and cooling costs by keeping indoor rooms warmer in cold weather and cooler in hot weather.

On the other hand, sound insulation concentrates on reducing or obstructing sound transmission within rooms or from the outside world. Noise disturbances are reduced by using materials like acoustic foam, mass-loaded vinyl, and double-glazed windows.

Modern construction must include insulation because it makes living and working environments cozier, quieter, and more energy-efficient, all of which contribute to energy conservation, environmental sustainability, and general well-being.

ICFs, or insulating concrete forms, are only used in new construction projects, yet they resemble concrete block insulation in certain ways. ICFs constitute an essential component of the building construction, supporting the concrete with foam blocks or boards.

The resultant level of thermal resistance is excellent. ICFs aren’t practical for retrofitting existing homes due to their integration into the construction process, needing professional installation.

3. Blanket Batts and Rolls

Blanket Batts and Rolls

Fibreglass and mineral wool are frequently found in blanket batts and rolls, which are among the most commonly used insulation materials. These insulating materials are adaptable for usage in floors, ceilings, walls, and foundations since they are available in large rolls or pre-cut pieces.

They are the material of choice for DIY projects because of how affordable and simple they are to install. However, in order to ensure your safety when handling hazardous materials, you must wear protection gear.

4. Reflective or Radiant Barrier Systems

Reflective or Radiant Barrier Systems

Systems for reflective or radiant barriers are made of thin, inexpensive materials with foil facings that reflect light. These insulation materials are frequently reinforced by kraft paper or plastic. These materials are useful for insulating floors, walls, and ceilings. They may be installed easily by DIY enthusiasts thanks to their accessibility.

They may not provide enough insulation on their own, so it’s crucial to understand that they are more effective when combined with other types of insulation material.

5. Loose-Fill and Blown-In Insulation

Loose-Fill and Blown-In Insulation
For insulating enclosed regions that are challenging to reach, like wall cavities or attics, loose-fill and blown-in insulation provide an efficient option. To make installation easier, this insulation can be poured or blown into these areas.

DIYers can hire equipment for private use, even though professional tools and knowledge are frequently utilized for blown-in insulation. Due to their adaptability, blown-in and loose-fill insulation are practical options, especially when insulating spaces of atypical design.

6. Spray Foam Insulation

Spray Foam Insulation

Utilizing specialized spray containers or equipment, spray foam insulation is applied. It first expands and then hardens, sealing tightly. This kind of insulation is appropriate for open wall cavities, attic floors, and existing walls.

After the foam has dried, it must be cut off if there is any extra. Spray foam insulation is especially useful in places that are difficult to insulate using traditional techniques.

7. Structural Insulated Panels (SIPs)

Structural Insulated Panels

Depending on the exact product and manufacturer, structural insulated panels (SIPs) are available with foam board, liquid foam, or straw insulation cores. Unfortunately, because it needs to be included in the home’s building, this form of insulation isn’t ideal for do-it-yourself projects.

To avoid any potential delamination throughout the installation process, experts are responsible for properly attaching, compressing, and curing SIP panels. In freshly built homes, SIPs are used to insulate the walls, ceilings, floors, and roofs, greatly boosting the home’s insulation capabilities. This ultimately results in less heat transmission and cheaper utility costs.

8. Rigid Foam Board Insulation

Rigid Foam Board Insulation

When upgrading existing insulation, do-it-yourselfers typically choose the reasonably priced rigid foam board insulation option. Depending on the exact product and manufacturer, the composition of this insulation may comprise components like polystyrene, polyisocyanurate, or polyurethane.

These stiff foam boards offer a high level of kinds of insulation materials and significantly slow down the flow of heat through steel and wood studs. For do-it-yourselfers, this insulation material is adaptable and suited for a variety of regions inside the house, including foundation walls, attic access points, external walls, interior walls, and ceilings and floors. However, interior and external wall sheathing is where it excels most.

Attic Insulation: 4 Efficient Ways to Insulate Your House

It’s winter time! And where people are busy taking out their winter clothes and blankets to cover themselves with an extra layer of padding. But, most of us are ignorant towards protecting our house from the chilling winds. Ever wonder why your house freeze in winters even when the heating mats or room heaters are turned on? In this article, you are going to get the answer. So read till the end.

When the chilling winds sneak into your house through invisible areas and make your house freeze, your energy bills hike up and you ask this question to yourself; why it is cold inside? My friends, it is because there are ignorant air spaces in your homes. These places are beyond your visible sight. One such place is the attic.

Attic insulation is an efficient way to save on energy costs and provide a comfortable warm house environment. A perfect approach to attic insulation can cut down energy bills by 10 to 50%. So, let’s get started with attic insulation.


Know these Tips before Attic Thermal Insulation

Analyze the attic condition:
An important step which will decide attic insulation type. Ask an expert to evaluate the condition, if your attic is having a trace of damp or wet and there is mold in the attic, then there is a high probability of having moisture retention.

Eliminate air leakage:
Look out for the gaps or cracks in the walls or roof of the attic. It is important to block such air passages to provide complete thermal insulation. To fill the holes, gaps or cracks, you can use caulk and expanding foam.

Opt well-suited insulation solution:
There is various kind of thermal insulation material that can be used for insulating the attic. Fiberglass, mineral wool, blown-in cellulose, spray foam, etc. are some kinds of insulating materials. Every thermal insulation material has different R-value so it is desirable to consult thermal insulation contractor.

Best 4 Attic Insulation to Enhance the Thermal Stability

Reflective Insulation:
Reflective insulation offers safe, cost-effective and easy to use install. They have high performance in terms of providing thermal stability. The reflective insulation material is a light-weight, toxic-free, air bubble lining that resists heat transfer and fiber free. The most prominent feature of reflective insulation sheets is they are environment-friendly.

Fiberglass Insulation:
Fiberglass is made up of melted recycled glass or silica to make fibers. They are light-weight than cellulose but you need a thicker layer to achieve a good thermal insulation as its R-value lies between 2.2-2.7.

Spray Foam Insulation:
It has high R-value and provides an effective barrier to air. Spray foam insulation is highly expandable and fills the gaps by sneaking into the minor cracks and stopping any air leakage. The spray foam is applied in the liquid form and then it expands and dries. Once dried the extra foam is cut out to have a uniform surface.

There are two types of spray foam:

Open-cell polyurethane spray foam- Its R-value ranges from 3.5 to 3.6 per inch.
Close-cell polyurethane spray foam- Its R-value ranges from 6.0 to 6.5 per inch.

Loose-Fill Cellulose Insulation: It provides effective insulation at all temperature and gives the best result when the weather gets cold. Its R-value lies from 3.2 to 3.8 per inch. It is useful for providing insulation in ceilings, attic floors, open or close wall cavities, etc.


Do’s and Don’ts for Attic Insulation


  • Remove and clean the damaged existing insulation.
  • Analyze the attic level of insulation and if it is below the beams or joists then add more insulation layers.
  • Measure the R-value of the material and surroundings. Add more layers to bring the desired R-value.
  • Seal the air leaks before insulating the attic.



  • Never install the attic insulation if there are any water leaks. First, repair the leaks and then insulate the attic.
  • Don’t install the insulation without wearing protective gears like gloves, masks, goggles, etc.
  • Never stand on the joints or beams. There is a risk of falling.
  • Never assume that your house has adequate insulation, it is better to measure the R-value and then decide the insulation material.
