Thermal insulation of buildings

To tackle the environment change every people should make their building that is thermally insulated. So that you can feel comfortable within home. T o know more go through https://blog.builtify.in/2019/08/how-to-make-your-house-thermally-insulated-builtify.html

1. Thermal Insulation of buildings by builtify

2. What is Thermal Insulation ? Thermal insulation is the reduction of heat transfer between objects in thermal contact or in range of radiative influence. In simple thermal insulation of buildings mean in hotter area keep the room cold and in colder area keep the hot. Also we can say thermal insulation of buildings means creating a shield around your home to maintain your rooms temperature according to your requirement.

3. Why thermal Insulation is necessary? Thermal Insulation is necessary for every one who are constructing buildings. In today's world Global warming is increasing day by day, for which wheather is changing Drastically. Due to weather change the world is getting temperature variation, some where it is very cold, and some other area it is very hot. And to get rid of extreme weather conditions man has invented every possible devices to tackle this problem. Such as A/C, room heater etc. But these equipments will have another issue that is electricity problem. You have to pay huge amount of money for bills and the gases releasing from this devices have very bad impact on the environment. So it is better to have make thermally insulated home rather than paying heavy amount of electric bills.

4. How to make your house thermally insulated? To make your house thermally insulated you can do in the following way. First while choosing materials for building construction choose the material which are thermally insulated . In that way halif of your work will be done. Second is you have to add materials for your home which can make your house properly thermally insulated.

5. Material that make your house thermally insulted . There are many materials which are thermally insulated. Doors and windows:- There are various materials available which can help to maintain room temperature. Such as fiber door, upvc door, pvc door and window, wooden door and window. It seems like doors and windows have no importance in insulation process , but they affect mainly as the air to room passes through them . Even if a small gap can make large impact in temperature.

6. Colour and surface:- Light coloured and smooth materials have higher reflectivity than dark coloured and rough materials. Whitewash, white paints, Marble have high reflectivity coefficient.

7. Thermal insulation by adding material Thermal insulation by adding material mean adding thermal insulators within walls, roofs or floor can make your house thermally insulated. There are different type of material available i market which you can add to your buildings and make them thermally insulated.

8. Types of Thermal Insulation Materials :- Fiberglass Mineral wool Cellulose Polyurethane foam

9. Fiberglass:- Fiber glass insulating material made up of fine glass fibers. It is mostly found in many homes. These fiber glass insulating material come in 2 types. One is in roll or batts and other one is rigid boards. Advantages :- It can be easily moulded into any shape and has mechanical strength that is so strong and stiff.It lasts for long time. No maintenance required . It is anti-magnetic, fire resistant, Good electrical Insulator, Fire proof. Disadvantage:- It needs to be re-gel coated every 5 years. It may not work if it is wet or damp during installation.

10. Mineral wool:- Mineral wool is a fibrous material drawn from molten mineral or rock mineral. Advantages:- It is installed as sheet into walls. It is fire resistant, Noise resistant. Disadvantage:- it is very expensive material.

11. Cellulose Cellulose insulation is plant fiber used in wall and roof cavities to insulate, draught proof and reduce free noise. Advantages:- Cellulose insulation is treated with boric acid which makes them fire resistant and makes them unpalatable.Have long term thermal insulating properties.Are cheaper than fiberglass. Normally health risk is less. Disadvantages:- Creates enormous amount of dust when installed. Cellulose insulation absorbs moisture easily and decreases the long term insulating properties.

12. Polyurethane foam Polyurethane foam insulation is made up of two chemicals. These foam insulation are spread on walls and roofs and then it solidifies to make an insulating material. There are two types of foam material , one is open cell spray foam. And another is closed cell spray foam. Reduces HVAC capacity requirements. Have stable insulation over time. Reduces air and moisture Infiltration resulting in a more consistent temperature.

13. How to choose insulating material:- During choosing thermal insulation material choose that which have better thermal insulation. And most important thing is whether the materials insulation capacity is long lasting or not. Next how much will it cost. How much will it take to install them. If it requires maintenance or not.

14. Heat Insulation of roofs Heat Insulating materials like a mud phuska can be applied externally. False ceilings with an air gap can be built internally. Water sprinkling on roof . White washing the roof before summer. Applying reflecting materials on the roof.

15. Heat insulation of exposed walls:- Construct wall of sufficient thickness. A brick wall of 23 cm thickness is adequate. Thermal performance can further be improved by Providing cavity walls (gap between two walls) and hollow bricks. Constructing a wall with suitable lightweight materials. Applying a light colour on the external surface.

16. Mud phuska terracing:- Mud phuska terracing and paving with bricks tiles is good for waterproofing and heat proofing of flat roofs. This is the best suited for hot and arid regions. Soil mixed with water is applied on a bitumen laid roof surface. The water quantity should be such that soil can retain it’s shape in the form of a ball. Generally , 150 litres of water is sufficient for 1 cubic meter of mud phuska. A slope of 1:50 and with 1” thickness at the end is adequate.
