puren FD-L

Format
1200 x 800 mm (external dimensions)
1185 x 785 mm (fitting dimensions)

Edges
all-around with stepped profile

puren FD-L insulating elements are particularly suitable for flat roofs with thin roof structures.

Advantages:

	To be installed using solvent-free puren roof adhesive
	B2 class building material acc. to DIN 4102
	Does not smoulder, melt or drop off while burning
	s_d-value > 1500 m (vapour-tight)
	Improved thermal reflection due to metallic outer layer
	High compression strength, compressive stress at 10 % compressive deformation acc. to DIN EN 826: > 100 kPa
	Water-repellent and resistant to chemicals
	Insulation element can be used from both sides for economical installation with low cut-off waste
	Water absorption acc. to DIN EN 12087: approx. 3 % by volume
	Good resistance to ageing
	Low weight

A U-value of 0.23* can be achieved with a thickness of just 100 mm.
