• Comparing Alpha Systems Superflex and LaSalle Bristol RV Roof Membranes
• The Alpha Systems Superflex RV Roof Membranes like part # AL42CV uses a TPO membrane and the LaSalle Bristol RV Roof Membranes like part # 3441700534142711435 uses a PVC membrane. The TPO membrane is more resistant to punctures and wear but the PVC membrane is more energy efficient. These are the main differences but they both work well on RV's. I recommend the TPO due to the increased strength which would therefore mean less maintenance. I have attached a full list of options below.
