Does perlite retain heat?

While it is true that perlite concrete will insulate more than regular concrete, in practice you will find that perlite concrete will retain heat and offer more thermal mass than it will practical insulation.

Also question is, how much heat can perlite take?

Perlite softens when it reaches temperatures of 850–900 °C (1,560–1,650 °F). Water trapped in the structure of the material vaporises and escapes, and this causes the expansion of the material to 7–16 times its original volume. The expanded material is a brilliant white, due to the reflectivity of the trapped bubbles.

One may also ask, what is better vermiculite or perlite? Perlite is a hard, highly porous material made by super-heating volcanic glass. Vermiculite retains more water and retains it for longer periods than perlite. Vermiculite affords slightly less aeration than perlite. For plants that thrive growing in a more-wet soil, vermiculite would do well as a potting soil additive.

does perlite decompose?

Perlite does not furnish any nutrients to the plants. Its particles do not decompose with time, so perlite is a better choice than vermiculite for plants that will be repotted infrequently.

What is perlite insulation made of?

Perlite & Perlite Perlite is a type of rock (a form of volcanic glass) which is mined, crushed, heated and thus expanded (4 to 20 x original volume) to form an inorganic insulating material.
