Hi there
Thank you for your comment,
The cladding is a composite board, that's better than wood but with the same effect, it comes in a wide range of colours,
Something that size with bifolding doors avarage between 8k to 14k
I'm in torrevieja from the 17th July for 2 weeks if you would like me to meet and measure, I can show samples of the product.
Thank you
Regards paul
