Double Glazing

• Reducing thermal loss and condensation and in providing sound insulation . 
• Outer pane has a heat reflective layer on its inner surface , the reduce emissivity of the coated surface reduces transmission through the air space
• Gaps filled suitable gases can further reduce thermal transmittance . 
• Double glazing with 6mm gap may be equivalent to a brick cavity wall . 
• In extreme conditions differences between the atmospheric pressure , enclosed air can cause explosion or implosion .
