Collector body is two chamber Aluminum profile , filled with polyurethane as thermal isolation. Werner collector has very small thermal loses. 

Absorber is selective with. 1 mm absorber thickness. Cooper tube is mechanically bounded in his "Ώ" Omega seal. Thermal heat transfer is realizing trough 75% surface contact between cooper tube and solar cell
