Thermal insulation is basically insulation to reduce the flow of heat. It keeps hot things hot and cold things cold. Insulation is basically anything that conducts heat slowly.
Heat is a form of energy and travels from hot to cold. Pretty much like water might flow from high places to low places, from the top of a waterfall downwards.
Insulation keeps you warm in winter by trapping the heat in the building, or trapping your body heat within your clothing.
Yes, you can use heaters or a fireplace to keep your home warm in winter. But you would need less electricity to keep the temperature comfortably warm if thermal insulation is taken into consideration when the building was made. Fibreglass batts or blankets can be used to insulate the floor as fiberglass is a poor conductor of heat. Cellulose or other loose fitting materials that trap air can be used to seal in the heat in the building by plugging up the nooks and crannies.
If the home is well insulated to keep the heat in and the cold out, you would need less energy to heat up the home. The result would be significant savings in terms of electricity. Not only would you be making wiser use of the earth's resources, with the price of fuel these days, you would save money in the long run as well.
As for thermal clothing, I keep thinking about the homeless guy in the movie The Day After Tomorrow. He couldn't afford thermal clothing, but he sure knew how to keep warm. Through thermal insulation. He stuffed newspapers into his clothes and paper is a poor conductor of heat. Hence body heat gets trapped under the newspapers, keeping the guy warm.
Wearing newspapers doesn't sound very comfortable and certainly not glamorous. For women who want to look great, you know, slimmer in spite of the insulation needed to keep warm, womens thermal underwear [http://buy-underwear.net/womens_thermal_underwear.htm] would be a better bet. Wear it as a second skin to trap your body heat. Today's thermal undies are not bulky. You could still look sleek in your favourite jeans without the necessary bulk of thick layers of clothing, if you choose the right thermal underwear.
