Because Harry Potter wanted every house to have insulation you got a problem take it up with him
Reflect heat (sunlight).
Heat rises so the best be would be to put a crap tonne of insulation in th roof
People should get solar panels to take advantage of the free sunlight falling on their roofs. The price of solar panels is reducing every year, and the return is coming more and more quickly. The more people have PV panels on their roofs, the fewer new fossil fuel (coal, oil and natural gas) power plants have to be built, reducing the rate of global warming.
Technology helps people live in space because it provides them with air and insulation also ability to work in microgravity.
You are likely thinking of the High-temperature reusable surface insulation (HRSI) tiles. These are part of the larger thermal protection system (TPS) which also includes the Low-temperature Reusable Surface Insulation (LRSI) tiles, Toughened unipiece fibrous insulation (TUFI) tiles as well as the Felt reusable surface insulation (FRSI) blankets and Flexible Insulation Blankets (FIB).
Fiber glass.
Also known as "living roofs", green roofs serve several purposes for a building, such as absorbing rainwater, providing insulation, creating a habitat for wildlife, and helping to lower urban air temperatures and combat the heat island effect
The advantages of having green roofs on schools is that they are environmentally friendly. They absorb rainwater, provide animal habitats and provide insulation.
To silence the wind noise on metal roofs
Viking houses were protected from the winter by using turf or sod walls, which offered insulation and kept the heat inside. The roofs were thatched with straw or reed, which provided additional insulation. Fireplaces or hearths were also used inside the houses for warmth and cooking.
the loft insulation is bad in that house
Kingspan insulation is used to insulate roofs, walls, floors, and HVAC ducts. This helps keep the heat inside the building and decrease energy costs used to heat the building.
Because they are there home made roofs and they are kind of poor people in life so that is why they have sloping roofs
Roofs are very fun to sit on, but no fun to fall off of.
To keep heat in - and cold out. Many buildings are poorly insulated ( the 'standard' house-brick is the main culprit. This lets heat escape through the walls (and roofs) of buildings. Insulation traps the heat inside.
The cottage owners refused to put thatched roofs on their heads because thatched roofs were often associated with lower social classes and were not seen as fashionable or prestigious. They wanted to maintain a certain level of social status and perceived thatched roofs as beneath them.
As Energysavingtrust.org points out, insulation of one's roofs and/or walls can prevent heat from escaping one's house. Because people who want to retain more heat would instead turn up the heat if it is escaping through porous walls, having insulation could thereby save energy.
