Q:Aluminum foil surface, SBS roll multilayer superposition, waterproof effect is good?

Generally speaking, SBS waterproofing membrane superimposed use, will certainly be better than the use of single layer. But the first time with the construction of aluminum thread with a little waste. Because aluminum Bu in coil plays only a reflective insulation function, so if the two house the first time it is not necessary to use the superposition with aluminum Bu, PE film can be second times, and then the aluminum coil Bu
