Castilla are your traditional half round tapered overlapping 2 piece Mission clay roof tile or as some people call it pan and cover tile. This is basically one of the oldest European forms of roof tile dating back to the Greek and Roman times, so you can be assured this is a tried and tested system.
Onda is a tile that brings the second oldest European style profile (what we in North America know as ‘Spanish S or Terracotta’), into the 21st Century. By combining the classic beauty of the Spanish clay roof tile profile with high tech double side and head locks they can provide a tile that will withstand whatever Mother Nature wants to throw at it.
Lusa is a Roman style profile, a one piece interlocking tile with a wide flat pan and smaller tapered barrel. This tile is just like a Spanish S style roof tile updated with modern technology. it has a thick butt (bottom edge) which gives a strong horizontal shadow line to the roofscape.
