Материалы для теплоизоляции
Материалы для теплоизоляции

На сегодняшний день существует просто огромный выбор материалов для теплоизоляции и буквально каждый день появляется новый их вид. Такие материалы играют основную роль в решение вопросов энергосбережения, а также способны значительно повысить комфорт жилых помещений.

Для каждой части здания существует свой определенный вид теплоизолятора, так, например, для утепления фасада используется один теплоизолятор, для крыши другой, а для фундамента - третий.

Все теплоизоляционные материалы должны обладать целым рядом теплотехнических свойств, которые необходимо учитывать для того чтобы выбрать действительно качественный материал для теплоизоляции:

Плотность. Такое свойство материала представляет собой величину, которая равна отношению массы вещества к занимаемым ею объему. От характера плотности зависят все основные характеристики материала-теплоизолятора. Про плотность следует запомнить одно - чем она меньше, тем материал более пористый. Теплопроводность. От такого свойства зависит то, как этот материал умеет сохранять тепло. Чем ниже теплопроводность, тем больше тепла он способен сохранять. На такой показатель влияют несколько основных факторов, таких как плотность материала, его вид, размер и коэффициент излучения поверхности. Влажность. Данный фактор является показателем содержания влаги в материале. С повышением данного фактора, теплопроводность теплоизолятора значительно повышается. Водопоглощение. Прочность.

На сегодняшний день существует несколько основных видов теплоизоляционных материалов:

Стекловолоконные. Такие утеплители производятся из волокна, получаемого вследствие переработки стеклобоя. Такие утеплители обладают достаточно низким уровнем огнестойкости и практически не способны сопротивняться деформации. Минераловатные. Такие утеплители изготовлены путем плавления определенных горных пород. Такой утеплитель является достаточно огнестойким.

Полимерные. Такие материал для теплоизоляции изготавливаются из разнообразных полимеров, методом экструзии.
