Work Detail

Surface Waterproofing With Asphalt Blanket, Two Layers, Including Application Of Asphalt Primer, E=3Mm. Af_06/2018 (Sinapi 98547) 3Mm Nanothermal Aluminized Blanket, (Oxidized Asphalt, Elastomeric Asphalt, Using Torch). Type Iii, Class B, In Compliance With Nbrs 9952, 9975 And 9574. Made From Special Laminated Aluminum Alloy, Resistant To Hail Impacts, With High Solar Energy Reflection Power And Partial Self-Cleaning. The Solar Energy Reflection Capacity Is Obtained By The Surface Mirroring Of The External Aluminum Foil, Associated With Its Diffusion Through The Angulation Of Surface Micro Grooves. The Micro Grooves, In Addition To Hindering Thermal Conductivity, Considerably Increase The Heat Radiation Area. Partial Self-Cleaning Is Achieved By The Hydrophobic Capacity Of The Micro Grooves, Providing The Formation Of Micro Droplets For Easy Evaporation And Water Sliding. The Antistatic Property Due To Grounding And Electrical Interconnection Between Panels Prevents The Accumulation Of Surface Dust. The Special Aluminum Alloy Slows Down The Aging And Degradation Of The Material. Formed By A Thin Thickness Of Refractory Material Resistant To Heat Conductivity, It Uses The Resource Of Space Nanotechnology, Inhibiting The Ranges Of Electromagnetic Heat Waves Below Infrared, Entering Into Reverberation With Such Waves, Reflecting The Majority Of Them Back To The First Layer Where They Will Be Dissipated In The Atmosphere. Such A Structure Thus Forms A Barrier For The Transmission Of Heat By Thermal Radiation, Composing A Second Impediment To The Conductivity Of Heat By Convection, Through Its Interior Void. The Nanothermal Elements Are Uniformly Aggregated, Adhered And Distributed Among The Bottom Of The Second Layer By A Stretch Of Heat-Resistant Polymers.
