What are the benefits of double glazing?

By having double or triple glazing added throughout your home, you will eliminate any drafts caused by your windows - meaning in the winter months your home will feel much warmer. In turn this will also mean that your energy bills will reduce - due to your home retaining a lot more heat and there being less need to turn the heating up. Double glazing will also make your home more secure and will reduce any unwanted outside noise.

Double glazing is not just practical, it’s also a beautiful way to update the look and feel of your home inside and out. With a range of different materials, finishes, styles and colours, our double glazing will give your home a fresh new look.

What’s the difference between double glazing and triple glazing?

Choosing double glazing will mean your home is warm and draft free but if you want that extra layer of warmth then triple glazing will hold onto the heat in your home even more. If you are unsure which is best for you then one of our experts will be happy to help.
