Hi Tess & All
The topic is on the front page of the Polaris World Forum under the Hacienda Riquelme section, (2 pages) but I have not actually joined it & so I cannot respond to the guys who have said 'email me for details'- however reading on to the latest - it appears that the Company that several are singing the praises of are a firm called Cristal Glide. Hopefully something useful will come up if you google this! I have a felling that this may be the Company that has an outlet at the Dos Mares Shopping Centre, but not 100% sure. Hope this helps.
I'm sure you won't regret having them fitted - we love the fact that we can choose how many 'curtains' we want to open or close, depending on how windy it is, how cold it is & whether it is raining etc & it effectively gives us an extra room, so that we don't have to clutter up our lounge so much. Additionaly, it gives an additional layer of security & so we certainly have no regrets, even though we had a few problems with the installation of ours & even though the 'draft excluder' bits that have been fitted on ours, keep falling off & we are regularly having to superglue them back! The concept is briliant - I would just choose a different Company if repeating this exercise, given our experiences.
Good luck!
Jan
