Commercial Insulation: Improving Energy Efficiency in Large Buildings
Commercial insulation is a critical building system designed to regulate temperature, manage energy costs, and ensure occupant comfort and safety within non-residential structures such as offices, warehouses, hospitals, and retail centers. Far exceeding the needs of a typical home, commercial applications demand robust materials and specialized engineering to address larger scale, complex building geometries, and stringent building codes. The primary function is to create a continuous thermal envelope, reducing unwanted heat flow to maintain stable interior conditions regardless of external weather. This directly translates to significant financial savings by lessening the strain on HVAC systems, thereby lowering energy consumption and utility bills.
A diverse range of materials is deployed to meet these challenges, each selected for its specific properties and application method. Common types include fiberglass batts, mineral wool, and spray foam, which is prized for its ability to expand and seal irregular gaps and penetrations. For industrial settings like…


The last item, about Global Cornish, caught my eye. After discovering my sweetheart's (Holly Odgers) Cornish mining ancestors in and around Goldsithney and Perranuthnoe, as a birthday gift I gave her some shares of Cornish Metals, Inc., a relatively new mining company in South Crofty. It's traded on the London and Toronto stock exchanges and we've enjoyed following its ups and downs, along with email announcements from the company. Holly has found it meaningful to be invested in Cornwall's mining future while honoring her Cornish ancestors' mining past.
Note: The share price indicated online is in GBX, which is "pence sterling." I was blissfully unaware of that when I invested in Holly's gift, incorrectly assuming it was "pounds sterling," so I initially purchased a modest $25 USD worth of shares. I'd intended to be about 10 times more generous than that and was able to make the necessary adjustment in a subsequent purchase.
[Disclaimer: I'm not a financial advisor (by any stretch), nor am I recommending investment in Cornish Metals.]
