With 1㎡ of Fiberglass, Protect 10㎡ of Forest: The Ecological Calculation of Material Substitution

I. The Ecological Cost of Traditional Materials

• - Steel: Producing one ton of steel consumes 1.5 tons of iron ore and 0.6 tons of coal, emitting 1.8 tons of CO2. For a 1000㎡ steel structure building requiring 150 tons of steel, it equates to consuming 225 tons of iron ore and emitting 270 tons of CO2 (equivalent to the annual absorption of 3000 trees).

• - Wood: Globally, 15 billion trees are cut down annually, with 30% used in construction. A wooden villa consumes 50 cubic meters of timber, equivalent to cutting down 50-100 trees, disrupting ecosystems.

II. The Ecological Advantages of Fiberglass

• - Superior Performance: The thermal conductivity of 1㎡ of fiberglass insulation material is 0.03W/(m・K), merely 1/300 that of steel and 1/50 that of wood. Under similar insulation effects, its usage is only 1/10 to 1/5 of traditional materials.
• - Energy Saving and Consumption Reduction: Using fiberglass insulation systems in 1000㎡ buildings can save 15,000 kWh of electricity per year and reduce CO2 emissions by 12 tons (equivalent to the ecological benefits of 600 trees). The proportion of renewable energy in production has increased, reaching over 30% for some companies.

III. The Ecological Value Throughout Its Life Cycle

• - Raw Materials: Made from natural minerals like quartz sand, which are abundant and renewable, avoiding the excessive mining of ores required for steel.
• - Production and Recycling: Advanced technologies have reduced energy consumption by 20%, with waste recycling rates exceeding 90%, forming a closed-loop ecological chain. Each 1㎡ of fiberglass reduces the use of 0.5 cubic meters of wood; for a 1000㎡ building, this translates into protecting a forest area covering 1000 trees.

Choosing 1㎡ of fiberglass means cutting down one less tree and protecting an additional 10㎡ of forest. From steel and wood to fiberglass, each material innovation writes the future of our planet. Let buildings not only be dwellings but also become green strongholds for protecting the Earth.
