💡 How does a radiant barrier solar heat shield actually lower indoor temperatures in hot climates?
It functions by reflecting infrared energy away from building envelopes before it turns into stored attic warmth.
This setup is mighty handy for anyone trying to tame sweltering roof spaces without ripping out old materials.
- Mirrored metal layers reject direct sunlight rays before hitting wooden rafters or drywall surfaces
- Airflow gaps around perforations prevent condensation buildup while letting trapped gases escape upward
- Lowered deck heat loads take massive pressure off residential compressor units during peak July days
