When ordering your Prior DIY conservatory we will supply the full fixing to enable you to assemble the conservatory. However, we do not provide flashing. The reason is that there are a number of options open to you.
The obvious choice is the traditional lead flashing. This will last for many years providing that someone does not come along in the middle of the night and remove it! It has the advantage of being easy to work and it will stay put. Another much cheaper option is called conservaflash, which, as it's name suggests, is desiged with conservatories in mind. Another lead free alternative is called Lacomet, which is much thinner than traditional lead but can be worked in the same way.
The key issue here is price. Lead being the most expensive and the other types being cheaper. The choice is up to you.
