Product Overview
rFOIL Ultra NT 1800S/P is a patented, US-manufactured radiant barrier designed to support the strict construction specifications of ICD 705 secure facilities. It serves as a proven technical countermeasure against RF eavesdropping (TEMPEST). Choose the solid vapor barrier version (1800S) for maximum RF attenuation, or the perforated version (1800P) when breathability is required to prevent wall condensation.
Materials
Single layer of woven polyethylene material bonded to and sandwiched between two highly reflective aluminum surfaces.
Available Sizes
- 48″ × 125′ (for both 1800S and 1800P)
- 48″ × 250′ (for both 1800S and 1800P)
- Custom sizes available
Insights
- Choose 1800S for maximum RF shielding (minimum 85 dB attenuation) and when a low-permeance vapor barrier (< 0.01 Perms) is required.
- Choose 1800P to allow breathability (2.69 Perms) in secure environments where moisture vapor buildup must be prevented.
- For RF shielding, overlapping and sealing seams is critical to prevent signal leakage; refer to SCIF construction guidelines for approved taping.
Warranty
10-year limited warranty; see Warranty sheet below for details
