Double-glazed windows are generally more expensive than single-pane alternatives due to their superior energy efficiency, noise reduction, and thermal insulation properties. While the initial cost is higher, they offer long-term savings on heating and cooling bills and increase overall property value.

However, drilling into double-glazed windows is strongly discouraged. These windows consist of two panes sealed with an insulating gas layer (often argon or krypton) between them. Drilling compromises the airtight seal, which leads to:

• Loss of insulating gas, reducing energy efficiency
• Moisture ingress, causing internal condensation and fogging
• Reduced soundproofing and thermal performance
• Potential structural weakening of the glass unit

If you need to install a lock or sensor on a double-glazed window, use non-invasive solutions such as surface-mounted locks, magnetic sensors, or external restrictors that don’t require penetrating the glass or frame seal. Always consult a professional glazier before modifying insulated glass units.
