Stop Condensation and Mould with Secondary Glazing

Are your windows crying every morning? Condensation on single-glazed sash and casement windows is more than just a nuisance; it is a primary cause of black mould, wood rot, and poor indoor air quality.

While many people try “dehumidifiers” or “moisture traps,” these only treat the symptoms. EcoShield Secondary Glazing treats the cause by thermally insulating the glass, keeping your home dry, warm, and mould-free.

Why Do Single-Glazed Windows Get So Wet?

Condensation occurs when warm, moist air from inside your home hits a cold surface—usually your original single-paned glass. This causes the air to reach its “dew point,” turning into water droplets that pool on your windowsills.

In period properties, this constant moisture leads to:

• Black Mould Growth: Which can trigger respiratory issues and allergies.

• Timber Decay: Rotting your original wooden frames from the inside out.

• Heat Loss: Damp air is harder (and more expensive) to heat than dry air.

How Secondary Glazing Eliminates the Problem

Professional secondary glazing creates a thermal break. By installing a bespoke internal pane, we create a managed air cavity between the original window and the room.

1. Warmer Internal Glass: The secondary pane stays much closer to room temperature, preventing moisture from ever forming.

2. Airtight Seal: Our precision-engineered frames stop the warm, humid air from reaching the freezing external glass.

3. Preserved Ventilation: We design our units so you can still open your windows to ventilate your home, ensuring a healthy balance of airflow.

Protect Your Health and Your Heritage Property

If you live in a Listed Building or a Conservation Area, you cannot easily install double glazing. This often leaves homeowners trapped in “damp” living conditions.

Secondary glazing is the council-approved way to fight mould. Because our system is completely reversible and sits on the interior, it protects the fabric of your historic windows while dramatically improving the living environment for your family.

The Benefits of a Dry Home

• No More Morning Towelling: Stop spending your mornings wiping down wet windowsills.

• Protect Your Decor: Prevent wallpaper peeling and paint flaking around window reveals.

• Lower Energy Bills: Dry homes retain heat significantly better than damp ones.
