1.SYNTHETIC
1. BIO SOURCES OF INSULATION
3. MINERAL INSULATION
Air, glass, wool, plastic, polyester,paper, rubber are examples of good insulators.
We can reduce heat loss from a building/house by using insulating materials. The cheapest way is drought proofing in which plastic is used to cover windows, secondly, double glazing of windows is also effective but costly. In double glazing, air is trapped and it acts as an insulator not allowing outside air to enter or exit!]]> 2020-03-30 06:14:47 UTC https://padlet.com/nuzhatjaved_79157/4j2esuvqk4xj/wish/481317137 Mueez Imran mueez7089 https://padlet.com/nuzhatjaved_79157/4j2esuvqk4xj/wish/481317949 The most common insulation materials are fiberglass, cellulose and foam. Insulation types include loose fill, batts, rolls, foam board, spray board and vapor barriers.To insulate our house we can start at the roof as hot air rises, so we can place fiber glass there with air sockets, because air is a terrible conductor of heat, same we can do with walls and put foam b/w them and with window we can put a lot of plastic strips that way the heat will not be able to escape

A variety of different types of home insulation exist including: batts and blankets, loose-fill, plastic foam, rigid boards, and reflective. ... Cellulose insulation is a fire-resistant material made from a combination of treated recycled paper and wood. It gained popularity in the 1970s when recycling was first introduced to the public.  Insulators are made of wet, processed porcelain. The fundamental materials used are a mixture of feldspar (35%), china clay (28%), flint (25%), ball clay (10%), and talc (2%). The ingredients are mixed with water. The resulting mixture has the consistency of putty or paste and is pressed into a mold to form a shell of the desired shape.  Types of Insulators. There are several types of insulators but the most commonly used are pin type, suspension type, strain insulator and shackle insulator.]]> 2020-03-30 06:16:49 UTC https://padlet.com/nuzhatjaved_79157/4j2esuvqk4xj/wish/481318887 Hiba Zulfiqar hibazulfiqar06 https://padlet.com/nuzhatjaved_79157/4j2esuvqk4xj/wish/481321635 Thermal insulation usually refers to the use of appropriate insulation materials and design adaptations for buildings to slow the transfer of heat through the enclosure to reduce heat loss and gain. The transfer of heat is caused by the temperature difference between indoors and outdoors. Heat may be transferred either by conduction, convection, or radiation. The rate of transmission is closely related to the propagating medium. Heat is lost or gained by transmission through the ceilings, walls, floors, windows, and doors.

I also learned about the three types of insulation which are Synthetic, Minerals and Bio insulation. I learned about there price and there effects . Insulation can be done by putting fyber glass insulators on the roof because the heat particle rises and the roof is the most heated part in the house ,

Mineral insulation is made of natural materials, such as volcanic rock, glass and sand. These materials are industrially transformed to produce wool. While this method may be cheap and fire resistant, it requires a lot of energy consumption and it releases carbon dioxide into the atmosphere. Synthetic insulation is created from crude oil, a non renewable energy source, meaning this method has a strong ecological impact. The final method, bio source insulation, is made from plant and animal based materials and is thus very eco-friendly, however it is also expensive . I also learnt that there are many ways to insulate homes. We lose heat through roofs, walls, windows and doors. Methods of insulation are: loft insulation (made of fiber glass, on roof), cavity wall insulation (made of foam with tiny air pockets, in wall cavities), double glazing (for windows) and draught proof (made from plastic sort of strips, used on windows and doors).]]> 2020-03-30 06:23:25 UTC https://padlet.com/nuzhatjaved_79157/4j2esuvqk4xj/wish/481325242 abdullah5611 https://padlet.com/nuzhatjaved_79157/4j2esuvqk4xj/wish/481327128 Abdullah noman

• Mineral insulation.
• Synthetic insulation.
• IO source insulation.
I also learnt that we can insulate our house in many ways to trap air inside the house. For example the roofs of our houses are the warmest part of the hoise as warm air rises upwards and we can insulate air house using something like fiber glass as air is a bad conductor of heat and its so small that there are no convection currents formed which reduces conduction. For our walls, we can use something like the cavity wall insulation and double glazing for windows. All these ways can help in the insulation of houses or buildings.]]> 2020-03-30 06:27:55 UTC https://padlet.com/nuzhatjaved_79157/4j2esuvqk4xj/wish/481329751 ALI HASSAN ali6354 https://padlet.com/nuzhatjaved_79157/4j2esuvqk4xj/wish/481330282 I learned about Insulation there are three types of insulation ~=
1.MINERAL INSULATION
~These are made from natural materials such as Volcanic Rug Sand and recycled glass bottles. It is transformed into wool which takes a lot of energy and releases a huge amount of CO2 in the atmosphere.
2. Synthetic Insulation
~It is created from crude oil polystyrene and polyurethane are some examples of it these are created by non-renewable primary materials.
3.'BIO~SORCE' INSULATION
~It come from animals and plants based material it has a low illogical impact the materials used are Renewable and requires little energy however are expensive to buy.

2:synthetic insulation 
3: biosource insulation 
I have also learnt that a house can loose its heat energy by loft insulation which is made of fibre glass as it traps lots of air . The air is a very bad conductor of heat.
Cavity wall insulation is that we pump a load of foam so no convection currents are bad at conducting 
Draught proofing is the cheapest way to refuce energy loses]]> 2020-03-30 06:30:36 UTC https://padlet.com/nuzhatjaved_79157/4j2esuvqk4xj/wish/481332565 today i have learnt how we can use insulation for less heat loss.We can trap air which is a bad conducter and so heat will not escape. saad8366 https://padlet.com/nuzhatjaved_79157/4j2esuvqk4xj/wish/481335830 2020-03-30 06:33:47 UTC https://padlet.com/nuzhatjaved_79157/4j2esuvqk4xj/wish/481335830 Ali abbas 8-A Aliabbas https://padlet.com/nuzhatjaved_79157/4j2esuvqk4xj/wish/481335836 There are 3 types of insulations :
1 mineral insulation :
Mineral insultaion is made up of vocanic errupt, sand and recycled grass the process in which its done cause alot of energy and release alot of Carbon Dioxide gas in the air  the advantages of this insultaion is that it is low of cost.
2 ) synthetic insultion :
Synthetic insulation is caused by crude oil. It uses little energy and however made by non renewable energy resources. The advantages of this insulation is that it has a capacity of strong insulation but is costly.
3 ) isonat insulation :
Isonat insulation is made by renewal materials and takes very little energy it has strong capacity of insulating nut it is hence expensive and costly.
4 ) insulting a house
While insulating a house we should take skme measures :
1) roofs :
Roofs traps alot of heat by air as air is a bad conductor of heat and by convection currents all the warm air rises up to roof so insulating it we should do the “ LOFT insulation “ which is made up of fibre glass it has the holes where air gets.
2) walls : for walls the perfect insulation is “ CAVITY WALL insulation is best.
These are the ways to reduce convection and conduction and the loss of heat / energy

(Bio source ).
(Mineral ).
(Synthesized).
We can also have house insulation as e.g: As the heat rises so the most heated part of a house is roof so we should replace loft insulation made up of fiber glass which traps lot of air . As a bad conductor of heat it is too small that convection current can't form . We have big wall cavities too which are full of air ,as bad conductor of heat. This makes convection currents to form so we can have a cavity wall insulation which pumps a load of foam which stops convection.

It is cheap and fire resistant but if you are handling it remember to use mask, gloves and protective glasses. Second type is synthetic insulation which is made from crude oil and an example is polyurethane. He advantages of this type of insulation are its strong cost and its powerful insulating abilities though it comes at a price of that it's made from non renewable resources. The third type is bio source insulation which is made from plant and animal related material such as the wool of sheeps. It can easily be manufactured and is the best with bringing low economical change but is manufactured in small amounts and therefore is expensive. From the second video I learned multiple ways to reduce energy cost and transfer heat. Due to convection warm air rises towards the roof which is where we use loft insulation made from fiber glass that traps alot of air which is good since air is a bad conductor of heat and air is trapped in such small particles that it stops the formation of convection currents. Then we go to the walls which have a big cavity so we use cavity wall insulation which also traps air. Then the windows where we can use double glazing which stops heat from going outside and the cheapest method draught insulation. We place sort of strips around the windows and doors which stops all hot air from escaping.]]> 2020-03-30 06:45:18 UTC https://padlet.com/nuzhatjaved_79157/4j2esuvqk4xj/wish/481349240 minahil6764 https://padlet.com/nuzhatjaved_79157/4j2esuvqk4xj/wish/481351891 -Mineral insulation:

Insulation types include loose fill, batts, rolls, foam board, spray board and vapor barriers. Tip: The type of insulation you need depends on which 
type is currently installed and the required R-value.
Synthetic: Synthetic insulation is designed to replicate the qualities of down, but retain them even when wet. 
It's made with polyester fibers that are arranged in 
different sized filaments and intertwined, mimicking 
down's lofty clusters.
Bio science : Bio-based insulation materials could replace conventional materials in many cases without loss of thermal performance. It’s a fact.
The heat insulation performance of bio-based insulation materials can compete with mineral or fossil-based materials, such as rock wool, glass wool and polystyrene.
