What is Foamglas insulation?

FOAMGLAS® cellular glass insulation is a lightweight, rigid, and durable material composed of completely sealed glass cells. It's non-combustible, provides superior compressive strength, moisture resistance, dimensional stability, and offers long lasting thermal performance.

Is perlite a good insulator?

Perlite is a common insulating material with low thermal conductivity. Perlite is very light. Perlite will absorb water but retain 100% of its insulating qualities once dry.

Is perlite harmful to humans?

Will vinegar lower pH in soil?

Vinegar Basics Vinegar is a diluted, liquid form of acetic acid, so adding it to soil naturally lowers the soil's pH and increases its acidity.

Why is my soil pH so high?

Soils may be alkaline due to over-liming acidic soils. ... Iron chlorosis in plants, caused by inadequate iron, is a common problem in alkaline soils. Phosphate, a macronutrient, may also be limited in these high pH soils due to its precipitation in the soil solution.
