For the ultimate in sealing performance for steel slabbed or skinned doors and steel enclosures. Also an excellent choice for OEM applications where steel surfaces are used.
Your door systems need to perform day in and day out in the real world. So does the seal you use. That is why only Pro-Lon door seals dare to show actual air filtration values after real world temperature cycling. Put Pro-Lon performance in your next project for a very special effect.
Testing to ASTM proposed "Standard Test Method for Determining Leakage Through Exterior Window and Doors under Specified Pressure and Temperature Differences Across the Specimen." The comparisons above were derived by force testing for air infiltration performance of the vorgin seals on a steel entry door. The laboratory produced benchmarks were compared to air infiltration values for each seal after one complete temperature cycle (70°, 125°, 160°, 20°, 0°, -20°, 70°), with the door exterior then cycled a second time and air infiltraion measured at 0° F.
