Window Inserts: A Smart Way to Upgrade Your Windows this winter

Are you looking to improve your windows but not ready to replace them all at once? Window inserts might be perfect for you. Whether you're looking for better insulation, noise reduction, or simply a refresh without the full replacement cost, inserts are a clever solution that works with what you already have.

In this guide, we'll explain window inserts, how they're installed, and whether they're the right option for your home.

What are window inserts? 

Window inserts are secondary window units that fit neatly into your existing window frames. They're designed to provide better insulation and noise control without touching the original frame or glass. That means significantly lower costs than full replacements.

Are window inserts worth it? 

If your existing windows are generally in good condition but could use a boost, then window inserts are a worthwhile investment. Here's why homeowners love them: 

  • Great for reducing drafts and outside noise

  • Less invasive than full replacements

  • Keep the original character of your windows.

  • More affordable than replacing the whole window unit

  • They're convenient for heritage homes or properties where keeping the original look is essential.

Different types of window inserts

At DuCo Group we provide different styles to suit your home and needs:

PVC window inserts

PVC window inserts are a popular choice due to their excellent insulation and low maintenance. They are lightweight, long-lasting, and work well in most modern homes.

Aluminium window inserts

Do you prefer a sleek, modern look? Aluminium window inserts are strong, slim-profile and suit architectural or industrial-style homes. Some models feature thermal breaks to enhance efficiency, so you're not sacrificing warmth for style.

How much do window inserts cost? 

Installation can vary depending on complexity, but it's still much cheaper than full replacements.

Ready to upgrade?

Window inserts are an innovative solution if you're keen to make your home warmer, quieter, and more efficient, without the cost or hassle of full replacement. Whether you're looking at PVC or aluminium windows, we'll help you find the right fit.
