Replacement Greenhouse Panels & Shed Windows


A greenhouse is a perfect addition to your property if you love growing plants, fresh fruit and vegetables. The walls and roof are typically made from transparent materials to allow sunlight to enter and create a warm and humid environment for everything to grow. Greenhouses are great to have if you a looking for a new hobby or fancy trying out a more self-sufficient lifestyle. 

Greenhouses can come in many different shapes, sizes & designs so it doesn’t matter if you have a small or big garden, you can get one to perfectly fit your space. 


A shed is typically something you would see in the back garden of someone’s home. It is typically a standalone structure that is used for storage or even as a workspace. Sheds can be made from various types of materials such as wood, metal and plastics depending on the practical and design requirements. Typically, shed windows are made from glass or plastic to enable some natural light and ventilation to enter the shed. 

Garden sheds are a versatile and useful addition to any backyard, they provide extra storage space and a dedicated area for hobbies and leisure activities. They can also add value to a property and enhance the overall appearance of a garden.

Why Would You Need A Replacement Panel or Window?

There are many reasons why you might need to replace your greenhouse panel or shed window and one of the most obvious reasons is due to any damages that may have occurred. If your greenhouse panel or shed window gets cracked or broken, it can cause a number of different problems with what you are storing inside. If you have delicate plants, vegetables or flowers being kept from the harsh weather, cold wind and rain entering through the broken gaps can cause an issue in growth. This can also cause issues in sheds if you have electrical equipment stored away, any rainwater that enters could potentially damage the items.

Another reason could be that panels or windows may have just become a little worn and dirty over the years so you just want to give it a simple upgrade. If you have had panels or windows in place for over 10+ years, they might also become less efficient so by simply switching out new windows or panels, it can give it a big refresh.

Acrylic Greenhouse Panels v Glass

One of the main reasons why people use Acrylic other than glass is due to the difference in impact resistance. Acrylic is a shatterproof material whereas Glass is fragile and prone to breakages. Another reason is due to the cost. The material cost of glass is typically more expensive than acrylic, and if you have to keep replacing your damaged panel, glass is definitely the more expensive option. 

Polycarbonate Greenhouse Panels v Glass

Polycarbonate is an exceptionally strong material and is over 200 times stronger than glass. Although they are both more expensive materials than Acrylic, Polycarbonate however is incredibly durable and will last for many years to come. Polycarbonate is also lighter than glass making it easier for any installations.
