The paired domes trap air between them to reduce heat transfer while the outer dome’s anti-UV coating helps slow sun damage to interior surfaces. Choose smoke gray, white, or clear covers depending on how much light and glare control you want.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the dual-dome design help control temperature and light?\u003c\/h3\u003e\n\u003cp\u003eThe bundle's inner and outer domes create an insulating air gap that lowers heat flow through the roof compared with a single thin cover. The outer dome also includes an anti-UV surface treatment that reduces solar degradation and helps protect fabrics and plastics inside your RV.
