Structural mechanical properties

Alfa Roof 28/2,5 sheeting comes in excellent, practical shapes and sizes, designed to meet the specific roofing application needs of industrial buildings. The structure of each individual sheet has been designed to give superior load bearing properties and provide ideal performance regardless of the application. The complementary accessories, recommended for a properly finished end result, incorporate the system’s functional qualities.

Optical properties

Alfa Roof 28/2,5 sheeting owes its optical properties to the carefully selected raw materials it is made with. The monitored and certified quality production process is designed to ensure lasting light performance to the highest standard.

Heat and sound insulation

Heat insulation is a characteristic of primary importance to the building industry. With its multiwall structure, Alfa Roof 28/2,5 achieves very high heat insulation values for excellent energy savings and offers considerable sound insulation for greater occupant comfort.

Fire performance

Fire safety is an essential requirement. Alfa Roof 28/2,5 has Euro class B s1 d0 certification issued by independent qualified laboratories. This means it does not contribute to flame spread and does not give off toxic fumes, in accordance with restrictive building regulations.

Behavior under environmental conditions

Alfa Roof 28/2,5 sheeting is protected against the harmful effects of UV rays. This protection is provided by means of the co-extruded application of a special treatment designed to ensure lasting optical, mechanical and performance qualities. With the cells sealed by heat sealing the ends of the sheet with hi-tech instruments, there is less chance of condensation and impurities building up inside the cells.
