The patented bituminous shingle welding has increased bonding strength. Adhesive surfaces form a single molecular system - as in metal welding
Slag is not used in the sprinkling - only pure basalt. Therefore, tiles do not give cheap shine in the sun
Tensile strength, resistance to UV radiation and the flexibility of the bitumen base comply with GOST 32806–2014. The warranty on flexible tiles of the Premium series is 50 years (Standard - 30, Europa - 20)
The sprinkle is painted using the firing method and practically does not change color during operation
