Whole window SHGC is lower than glass-only SHGC, and is generally below 0.8. Solar heat gain can provide free heat in the winter but can also lead to overheating in the summer. How to best balance solar heat gain with an appropriate SHGC depends upon the climate, orientation, shading conditions and other factors.

Biuret is a chemical compound with the chemical formula C 2 H 5 N 3 O 2. It is also known as carbamylurea. It is the result of condensation of two molecules of urea and is a problematic impurity in urea-based fertilizers.This white solid is soluble in hot water.he biuret test is a chemical test for proteins and polypeptides. It is based on the biuret reagent, a blue solution that turns violet upon contact with proteins, or any substance with peptide bonds.
