Blown double glazing compromises energy efficiency and appearance. Understanding the signs, causes, and solutions helps homeowners address this issue effectively. Upgrading to replacement uPVC double glazing or triple glazing provides a long-term fix with improved performance and aesthetics.

Signs of Blown Double Glazing

Blown double glazing shows clear indicators that homeowners should not ignore.

Condensation Inside the Glass

Moisture trapped between the panes creates foggy windows. This condensation results from the seal failing, allowing air and water to enter the unit.

Misted or Cloudy Glass

Cloudy or hazy glass obstructs views and reduces natural light. The misting results from dirt and moisture accumulating between the panes.

Reduced Insulation

A noticeable drop in indoor comfort often signals blown glazing. The loss of insulation makes rooms colder in winter and warmer in summer.

Causes of Blown Double Glazing

Blown glazing occurs due to several reasons, most involving wear or damage.

Age and Wear

Over time, the seals in double glazing degrade due to exposure to weather, UV light, and temperature fluctuations.

Poor Installation

Incorrect fitting places strain on the seals, causing them to fail prematurely.

Physical Damage

Cracks, chips, or impacts weaken the unit and allow air and moisture to enter.

Extreme Weather

Rapid temperature changes and harsh weather conditions cause seals to expand and contract, leading to eventual failure.

Problems Blown Double Glazing Causes

Blown double glazing affects your home in multiple ways.

Higher Energy Bills

Damaged glazing loses its insulating properties, forcing heating and cooling systems to work harder.

Uncomfortable Indoor Environment

Rooms become drafty and less energy-efficient, reducing overall comfort.

Compromised Aesthetics

Misted or cloudy windows spoil your home’s appearance, both inside and out.

Solutions for Blown Double Glazing

Addressing blown glazing promptly prevents further issues.

Short-Term Fixes

You can temporarily seal gaps to reduce drafts, but this does not solve the root problem.

Replace the Glass Unit

Replacing the failed glass unit restores insulation and appearance. However, the frame condition should also be assessed during this process.
