Replacement Shed Window Details

When it comes to constructing your dream shed, considering the shed windows is as crucial a decision as the walls, doors and roofing. Shed windows are what transform your space and give your shed some light, whether your shed is a functional area or a place where you tend to relax.

Replacing your shed windows with acrylic is often more cost-effective than other window replacement options, such as glass. This is because it's a relatively inexpensive material, and the durability and low maintenance requirements mean that you won't have to replace the windows as often.

This superior strong material can be purchased in varying thicknesses to provide further levels of insulation for your shed. No matter the size of your shed windows, we can provide you with clear materials that fit your measurements at an inexpensive price. Installing new shed windows is usually a straightforward process, and can often be completed by a DIY enthusiast with the right tools and a little bit of experience. This means that you can save money on installation costs, and have the satisfaction of completing the project yourself.

We have constructed guides which can help you choose between acrylic sheets or polycarbonate, as well as assist you in how to replace your shed windows so that your project is easy to accomplish. Our shed window alternative to glass is lightweight in comparison to traditional glass, meaning that they are easier to handle, lift and install.

They are extremely durable, and resistant to impact, weathering and UV radiation. Up to 10 times stronger than glass they don’t show any sign of ageing with continual use, and although slightly more expensive - our polycarbonate option is half the weight of glass and up to 200 times stronger. This makes both glass replacement alternatives for shed windows ideal for use in outdoor houses where windows are exposed to the elements and may be subject to accidental damage.

Further to this, both materials offer excellent light transmission properties at over 90% - higher than most types of glass. This can be especially useful if you use your shed as a workspace, as natural light can help to make the interior of the shed more inviting and comfortable. This can also improve energy efficiency in your shed by reducing heat loss which is why our clear sheets are commonly used for secondary glazing too.

Key Features of Shed Windows

Clarity icon

Durable

With a higher impact tolerance to glass, our shed windows make a stronger, long-lasting alternative. Polycarbonate is 200 hundred times stronger than glass and 30 times stronger than our regular acrylic, as well as being shatter-resistant. At its thickest point polycarbonate is also resistant to bullets!

Weather Resistant Icon

Malleable

Clear acrylic sheeting is easy for us to fabricate and it can be cut, drilled and shaped to any of your requirements so it’s a flexible material to work with.

Built to last icon

Weather resistant

Our replacement shed windows are UV and weather-resistant, as well as resistant to prolonged exposure to sunlight. They are also resistant to most chemicals and have a low moisture absorption rate so perfect for outdoor applications.

Durable

Excellent Clarity

All our shed glazing options give excellent optical clarity, ranging up to 92% light transmission, higher than most types of glass, making them an advantageous option for use in windows or as a skylight.

Lightweight

Lightweight

They weigh half as much as an equivalent thickness of a glass pane, making installation, transportation, and handling an easier option for fitting your shed windows yourself!

Malleable

Inexpensive

Our replacement shed windows are much cheaper than a glass window replacement. They are also built to last and shatter resistant, so you won't need to replace them as often.

Maintainable

Maintainable

All of our shed window options are equally easy to clean, with just warm soapy water and a microfibre cloth.

Food Safe

Salt Resistant

Both materials we use for shed windows are salt-resistant so they are ideal if you live in coastal areas.

Perspex Technical Sheet

100% recyclable logo

100% Recyclable

Perspex® Acrylic is 100% recyclable. Waste products can readily be recovered from the original raw material (the monomer) and re-used in a new sheet.

Perspex® has been manufactured in the UK for over 85 years and still takes place on the same site in Lancashire as it did in the 1930s. This short supply distance to our UK customers helps reduce ‘product miles’ from the manufacturing plant to the end user.

Numerous different investments have already been made by Perspex® to lessen the impact on the environment. Annual waste consumption has been reduced by 24 million litres, and almost 800 tonnes of carbon dioxide have been saved every year as part of a hot water recycling project. At Cut My, we work to be more sustainable by using all of our offcuts to heat our manufacturing facility. We are also currently working towards reducing our packaging.

Frequently Asked Questions

What is the best material for shed windows?

Clear Perspex Acrylic sheeting provides up to 92% light transmission, higher than most types of glass, so is a preferable option to glass for use in windows or roofing for sheds.

How thick should shed windows be?

We recommend a minimum thickness of 3mm however we have found that for some, 2mm is ideal for smaller sheds, or for use as secondary glazing for the colder months.

Should I put a window in my shed?

While sheds often have electricity, having natural lighting in your shed makes the whole room feel more habitable, even if it is used as additional storage. We find that this makes windows a favourable option.

Are plastic windows better than glass?

Our polycarbonate is 300 hundred times stronger than glass, meaning that its resistance to impact and the elements will see polycarbonate shed windows outlast any glass alternative.

Can you replace the shed window?

We are able to provide acrylic sheeting in either Clear Perspex acrylic or polycarbonate exactly to your specifications and measurements making it easier to replace than traditional glass. We have also made a helpful installation guide to assist you.

Ordered the 3mm thickness. The cut to size service is great, so a good idea when the shed you have is fine but the windows need repairing. Delivered in reasonable time, very well packaged up and protected.
