The space enclosed by the building wall is defined as the attic and is located directly under the roof. This is the area which is usually not occupied by anybody, and so it is unheated. Thus attic insulation is necessary as according to the statistics poor attic insulation will account for up to 15 % of the total energy loss in the house. Thus, insulating an attic is vital in the home energy saving process.

How Attic Insulations reduce electricity bills?

Attic insulation increases the value of a house and is an effective way to reduce the electricity bill. Given below are the tips which will help to perform proper insulation in your attic.

  1. Selecting the appropriate attic insulation type along with its R-value is important. Thus, there should be enough information about your budget, the building design, and its climate.
  2. The attic insulation should be in your budget range, besides it meets your requirements. The most common insulation types are cellulose, fiberglass batt, and spray foam insulation.
  3. Fiberglass insulation can be installed easily and long insulation stripes are used for it. Any color can be given to it.
  4. Cellulose attic insulation can be blown inside the covering and also provides good coverage for even smallest spaces. It’s also available in the form of Insulation bags. It can be applied with the help of insulation blower.
  5. Spray foam attic insulation works by stretching and expanding. It covers small holes, gaps, cracks and openings effectively. To apply this insulation functional tools are required.
  6. It’s always advisable to use high density insulation for exterior walls.
  7. One must consult a professional, whether to install attic vents or not.
  8. The attic insulation should be placed nearby light fixtures as that’s the main source of heat loss. The framings exhaust fans, boundaries, chimneys, soffit vents, lighting fixtures, and pipes should be sealed outside of the attic.
  9. Read the manuals thoroughly, before installing the attic insulation. Follow all precautionary measures mentioned. Always hire experienced and specialized professionals for applying spray foam or cellulose attic insulations.
  10. If the insulation is lifted from any place then fix it properly or replace it immediately.
  11. One should not block soffit vents to ensure attic ventilation.
  12. All leaks should be repaired before starting the insulation procedure, to make the attic insulation work effectively.
  13. The attic trap and access door should be covered properly.

Parts of temperature management system: Attics insulation

Attic is considered to be the space between slanted surface of the roof and the ceiling of a house. The shape of attics being very awkward usually converted into storage place. Nowadays attics insulation takes place in order to control temperature. In the modern age uncovered attics are used generally for ventilation purpose. As hot air moves upwards following scientific rules so attics insulation is the best area to be targeted as insulator. According to experts there are various materials which can be used for attics insulation. But they all have their own pro and cons.

Various attics insulation upgrades:

ü  Fiberglass batts

This insulator is famous because it is easy available and easy affordable. Floor joists install these battles. Unfaced insulation is used generally.

As it requires multi layer installation so it should be installed very carefully. Otherwise this installation may lead to energy loss.  Fiberglass batts installation is not able to stop movements of air.

ü  Blown insulation

This attic insulation mainly consists of two types of installation with special equipments. It is a very quick process and follows full area coverage.

In this process very thick layer of material installation is followed strictly.

ü  Spray foam

This kind of installation takes place with spray foam of a thick layer between the roof walls.

This is the most expensive attics insulation.

ü  Rigid foam

It is used to create barrio of air and thermal. It is far better than spray foam as it provides facilities of ventilations. Joists’ damage of moisture is stopped in this process. It can hold the heats by reflection process and save heating energy.

The system is not widely available and costly also.

Attic insulation is a very good consideration to keep energy costs cheaper. It is a very charming process to make your home cool in summer and hot in winter.

  • Air tight the ceiling

The main functionality of attic insulation is to decrease the transfer of temperature from one side to another. That’s why hot air can mix with cool air properly. But it is not a conductor of current.

If current enters the insulator then it may harm many of insulation functionalities.

  • Pre-Wire the Attic for Current 

The main reason behind insulator destruction is attachment with internet, phone lines, connection with satellite etc. So if these things get in touch with attic insulation, pre-wire the Attic.

  • Ventilation of Attic

Attic Insulation should get proper ventilation for surviving.

  • Exhaust fan of solar Attic

Along with sun rays the fans gets started and draws hot air out of the attic and cool air takes place from the lower part of attic. Everybody who experienced it always admired it.

When you are finding ways to keep your cooling and heating costs down, then you must look for installing attic insulation. Attic insulation is an extremely important issue to look for, and it is important for you to make sure that you are doing everything for saving money a lot of money, by not allowing the heating bills to climb up.
The installation of attic insulation depends on the current set up of your attic. Like, if the attic finished with plaster up or drywall then any of the two ways can be picked up to get the insulation in:

  • One can rip out all of the plaster or drywall, install the insulation, then put the walls back up.
  • Or one can cut small holes throughout, then fill the walls with insulation that has been blown in and then repair the holes in the wall.

Thus you can go for any of the attic insulation process, by considering the money and the time involved in doing that.

  • If the walls in the attic are quite beat up but the space is big enough that can be transformed into an active room then it’s a good idea to tear the old walls out then install new ones after the attic insulation is installed properly.
  • But if the attic is such a crawl space that no one is really going to see then you might cut holes in the walls to blow the insulation in, even if your walls are not that pretty and good to look at. Thus, this time you are at the pricing though.
  • If you are able to blow the attic insulation in yourself by renting the machine then that is better rather than to hire someone to do it. Hiring someone will just double the cost.

Thus, if you know how to drywall on your own and have a limited budget, then going for ripping out and replacing the walls is the option which makes more financial sense.

Different types of attic insulation:

Given below are the commonly used attic insulations,

  • Loose filled Cellulose Insulation
  • Stabilized Insulation of Cellulose Insulation
  • Loose filled Fiberglass and mineral woollen Insulation
  • Batts Fiberglass and mineral woollen insulation
  • Rigid Boards Expanded Phenol or Polystyrene foam insulation
  • Sheets of Butyl and Nitrile rubber foam of Cellular Foam Insulation etc

Given below are the areas of heat loss in an attic that have been identified by researchers:

  • Roof
  • Air vents
  • Attic floor
  • Attic access
  • Poor insulation in hot water tanks and plumbing and,
  • Poorly erected hot/cold air distribution ducts

The best part of the whole issue is that out of all insulations of old or new buildings, attic insulation is the easiest to tackle. In most cases this can be carried out by semiskilled professionals as well and can be done during the weakened only.

Given below are the pros and cons of blown attic insulation:


ü  It is one of the easiest to install, and most contractors prefer this insulation.

ü  It is also the least expensive out of all of the insulation types.

ü  The installation is very fast which may take around 2 hours depending on the size of the attic.

ü  Batt insulation can also be installed over the top of blow attic insulation, for added insulation but will cost more.

ü  It covers everything, leaving few gaps.


ü  The r-factor in it is the lowest of all insulation types.

ü  Even if it is installed correctly, the r-factor may vary greatly since it is difficult to blow the insulation uniformly across the attic.
