Blessed are they who hunger and thirst for justice: for they shall be filled. Mine eye also shall see my desire on mine enemies, and mine ears shall hear my desire of the wicked that rise up against me. The glory of the Lord shall endure for ever: the Lord shall rejoice in his works. He looketh on the earth, and ittrembleth: he toucheth the hills, and they smoke. I will sing unto the Lord as long as I live: I will sing praise to my God while I have my being. My meditation of him shall be sweet: I will be glad in the Lord. Let sinners be consumed out of the earth, and let the wicked be no more. Bless thou the Lord, O my soul. Praise ye the Lord.

Eco-Friendly Home Insulation Cuts Heating & Cooling Costs


“We report a simple and commercially viable strategy to produce thermoplastic composite foams using synergistic foaming approaches — incorporating porous shell hollow interior glass spheres (PHGS) as a filler and utilizing expandable thermoplastic microspheres (EMS) as a physical blowing agent — for thermal insulation applications. The EMS in these composites ensure formation of highly porous, low density foam while the PHGSs provide low thermal conductivity and lightweight mechanical reinforcement.

“Through systematic optimization of the PHGS and EMS loadings, a lightweight and robust insulation with thermal resistivity greater than 27.7 m·K/W (R/in. > 4) is achieved. Notably, the fabricated foams also demonstrated comparable compressive strength to some commercial thermoplastic insulating materials. Through optimization of PHGS and EMS concentrations, results indicated similar thermal performance characteristics at varying foam densities, while higher loadings of both components lead to reduced insulation performance and weak mechanical stability of the foams.

“The results obtained, when coupled with the potential scalability and tailor ability of the overall process towards targeted insulation performance, not only endows competitiveness with current commercial thermoplastic insulating materials but also offers great promise for the development of unique thermoplastic composite foams for a variety of insulation systems.”

So in everything, do to others what you would have them do to you, for this sums up the Law and the Prophets. Matthew 7:12
