Energy Efficient Thermal Break Windows



You’ve seen it before. Water droplets on your windows on a cold day. Steam on your mirror after a shower. A damp look on the walls in winter.  What you’re seeing is condensation. But what is condensation? And does it matter?


Condensation occurs when water vapour or steam cools down and transitions from a gaseous state to a liquid state.

In homes, you may see condensation in the form of water droplets or moisture on your windows, doors, or walls. It occurs when the surface temperature of your windows, doors, or walls is cooler than the temperature of the air inside your home.

Often, condensation in your home will be most visible on your windows. But if they appear on your windows, chances are it’s happening elsewhere, too.


When left unchecked, condensation can cause several problems around your home, including dampness, mould growth, wood rot, and corrosion.

None of these outcomes are great for your health or the health of your home and its structure.

That’s why it pays to do all you can to reduce condensation in your home.


There are several everyday things you can do to reduce condensation in your home.

In particular, you should ensure that any warm, moisture-laden air from your bath, shower, kitchen, or clothes dryer exits your home rather than staying inside it.

Use your bathroom extractor fan during and after your bath or shower. Turn on your range hood extractor when cooking. Open your laundry window or door to let hot air escape when your clothes dryer is running.

Some air conditioners have dehumidifying settings to help minimise condensation. And you can always wipe down wet surfaces to reduce the risk of condensation leading to bigger problems.

However, if you’re truly serious about reducing condensation in your home, then you need to take a closer look at your windows.


At Bradnam’s, we take the problem of condensation seriously.

It’s one of the reasons we developed our thermal break range.

All our thermal break windows and doors feature double glazing with a warm edge spacer and reinforced polyamide extrusions that separates the exterior and interior surfaces.

These components create an effective insulated barrier. This barrier ensures the temperature of the air inside your home and the internal surface of the window is similar.

When the internal surface temperature of your windows or doors is similar to your room temperature, you no longer have a recipe for condensation. That’s because you’ve removed a key condensation ingredient: a colder-than-air surface.

As a bonus, our thermal break range also improves your energy efficiency by making it easier to keep your home warm in the winter and cool in the summer.
