Disposing of Double Glazed Windows

12th May 2020

The environmental credentials of uPVC double-glazed windows are now well known.

With improved insulation, they help to keep your home warmer and increase energy efficiency as a result.

What is less well-known, but equally important, is that new windows are often manufactured using advanced and environmentally friendly practices, as well as being manufactured from recyclable materials. 

But in order to have the most positive impact from this, it’s important that you dispose of your double glazed windows correctly. 

Recyclable materials

There are two key materials used in your double glazed windows and you’ve probably already guessed what they are: uPVC and glass.

uPVC is widely and easily recycled so as long as you dispose of it correctly, you can rest assured that it will go to good use and not to landfill.

The glass is a little more tricky as the different types of glass have a different chemical makeup and therefore a different melting temperature. It can be recycled, but you have to make sure you take it to the right facility. 

If your windows date back to the 70s or sooner, you may struggle to recycle all of the materials due to the lead paint used. This will need to be disposed of in accordance with strict regulations and you should consult your local authority for guidance to ensure they are disposed of correctly. 

Disposing of the materials

First, remove the window from the frame by unscrewing the hinges.

Then you need to separate the glass from the casement using a hammer and chisel.

Once you’ve separated the glass from the plastic, you then need to identify the best place to take them for disposal. Your local council will point you in the direction of an appropriate facility, usually a building materials reuse centre. 

uPVC windows are a great way to ensure you are doing your bit for the environment. Not only do they help with energy efficiency in the home, but the recyclable materials used and sustainable manufacturing processes, means each window is made and installed with environmentally sound principles in mind.

So helpful - Steve was so patient while I chose my new front door - which was installed by PBM Exteriors who recommended MLI. I cannot emphasise how much my new and very contemporary front door makes the house look so modern and 'new'. Just huge thanks for great service and an amazing grey anthracite grey front door and side panels!
