Natural tile Alaska Double Roman

In Europe, there are several different models of manufactured concrete tiles with similar physical, chemical and mechanical characteristics, but the most widespread model is DOUBLE ROMAN. The shape of the roof tile has been developed over the years, and each of its elements is designed to perform various functions. the wavy shape reduces the zone of active wetting, the longitudinal double folds and paired grooves on the front surface protect against moisture penetration, the supporting ridges and spikes are designed to transfer their own weight, wind and snow loads to the crate and the underlying shingles and ensure reliable attachment of the shingles to the crate bar, side overlaps form a visually continuous row of tiles, transverse ridges on the back side increase the rigidity of the tiles.
