Frequently Asked Questions (2)

The 4mm sheets come in clear, bronze, and patterned colours and textures.
Typically, sheets are not made to be bended. However, certain type of 4mm sheets can be deformed.

4mm Polycarbonate Sheets

The smallest width of polycarbonate sheets we stock here at ERoofing are 4mm polycarbonate sheets. Despite their size, they are extremely strong and resistant to water, making them versatile and suitable for various roofing needs.

4mm polycarbonate sheets are fantastic, for instance, for cloches and greenhouses. A cloche is an odd, portable structure which is basically a cross between a diving bell and a greenhouse. The result is a mini-greenhouse that can be put over an individual plant or an individual patch of plants to provide the same benefit as a greenhouse. 

4mm sheets can also be cut with a knife which makes them excellent for tasks like replacing broken glass in interior settings. The high level of insulation relative to size and weight also makes 4mm sheeting good for permanent interior glazing. 

Cheap 4mm polycarbonate sheets

At ERoofing, we stock a range of affordable 4mm polycarbonate sheets suitable for greenhouse, glazing, and other related projects.
