Matecno Sandwich Panels

Features :

	High load bearing capacity at low weight.
	Excellent and durable thermal insulation
	Absolute water and vapour barier
	Excellent air tightness and free of thermal bridges which results in considerables energy savings
	Surface finished facings providing resistance to weather and aggressive environments
	Capacity for rapid erection without lifting equipments;easier installation in hostile weather conditions
	Easy repair and replacement in case of damage
	Long life and very low maintenance cost
	Good sound insulation
	Reasonable fire reaction and resistance

Self-supporting metal panel,insulated with polyurethane,for pitched roofs with a minimum stope of 7%.

Profile Specification :

Table of safe spans Values guaranteed with external face in steel,0.5mm thick,and internal face in feel,0.4mm thick or with both faces in aluminium 0.6 thick external face in aluminium,0.6mm thick,and internal face in steel,0.5mm thick.The spans l (m) as a function of a uniformly distributed overload p (kgf/m2), have been obtained from load tests carried out in Metecno laboratories, and provide a deflection f = l /200 with a safety co efficient that complies with the UEAtc standards for insulated panels,which have been established and are implemented by primary European Certifying Orgnizations.

Witht external and/or internal steel thickness interior to the above mentioned ones,the guarantee on the admissible loads for the spans indicated in the table is maintained on the deflection limit and the safely coefficient.

K value is thermal Transmittance Co-efficient expressed in Watt/m²⁰C and Kcal/m²h⁰C
