Thermally Efficient

Our double glazing has a WER rating of “A” to guarantee the most thermally efficient windows and doors in the Chessington area. This means that our windows help to insulate your home, retaining heat better and preventing cold draughts from getting in.

Heating your home regularly is expensive and detrimental to the environment, as it is one of the biggest contributions to the UK’s carbon emissions. Replacement double glazing is an affordable and effective way to improve your home’s energy efficiency, as it can reduce the need for you to heat your home as regularly by helping to retain heat.

This also means that you could see a reduction in your energy bills because you are heating your home less!

Safe and Secure

We know that the most important factor to you when choosing new double glazed windows and doors is that they keep your home safe. At Marathon Windows, we ensure just that. Our windows and doors are Secure by Design accredited, a police backed initiative to improve building safety regulations.

uPVC double glazing and aluminium double glazing also provide enhanced security as they are robust materials. uPVC and aluminium profiles will not become weather damaged or lose their structural integrity when faced with force, so you can rest assured that they are keeping your home protected.

Double glazing is a safer option than single glazing because an additional pane of toughened glass provides your windows and doors with an added layer of protection against breakage.


We have a large range of double glazed window styles so that you can find the perfect one for your Chessington home. You can mix and match styles throughout your house or just have one replacement double glazing option. Either way, Marathon Windows are here to help.

Our range includes uPVC Windows, including Casement Windows, Tilt and Turn Windows, Sash Windows and Flush Casement windows. All of which come with double glazing as standard and can be finished in a range of colours. You can choose from White, Cream, Grey, Irish Oak, Golden Oak or Rosewood, depending on which one best suits your house.

The woodgrain effect foils are textured and multi-dimensional in colour so that you can benefit from the authentic appearance of wood with the modern performance of uPVC. All of our finishes are long-lasting and low maintenance, so all you need to do is wipe them with a damp cloth for them to continue looking vibrant and fresh.

Our uPVC double glazing is BBA Certified and manufactured by Eurocell. Many are also made from 100% recycled materials so that you can be confident knowing that your windows are a sustainable option for your home. Marathon Windows also offer a 10-year guarantee on all of our double glazed windows, so you know that your investment is covered for the next decade.

We also have a selection of double glazed doors. These can be matched to your existing window casings, that is if you don’t decide to have our windows installed in your home too! We offer uPVC doors, residential doors, composite front doors, stable doors, French doors, patio door, and uPVC or aluminium bifold doors. So there truly is a style for any Chessington home.

All of our doors are fitted with double glazing as standard, which helps improve your home’s performance. This is particularly important for our range of patio doors, as the large-scale glazed panels take up a big portion of the door. Our double glazing boasts low U-values so that you can benefit from increased thermal efficiency and optimal light transmission.

We have a solution for all larger homes, as well as smaller ones. Our slimline sliding doors are perfect for homes with less space, as they do not need a swing or folding area on either side. On the other hand, larger homes can benefit from our patio doors, creating beautiful, unobstructed views of the outside.
