Energy Efficiency

Simco offer 'A', 'B' or 'C' energy rated windows, doors and conservatories. By getting your old windows replaced with 'A' rated windows you will save a small fortune on your annual utility bills as 25% of heat is lost through windows on a typical household. The way which it is achieved is by having K glass, filled with argon gas and warm edge spacer bar. A typical household would save around £350 if upgrading from 'C' rating to an 'A' rating
