Thermal Insert Components and Assembly
1. Glazing
a. Manufactured within the United States of acrylic sheeting, also
known as PMMA (Poly Methyl Methacrylate) in thicknesses
ranging from .118” to .236”.
b. Acoustic Grade (AG) Inserts that reduce the noise coming
through operable single-pane windows by 18.9 dBa. Available in
Commercial & Blackout Grades.
c. Blackout Grade (BG) These black panels block all light coming
through your windows and provide the acoustic dampening
and thermal insulation of standard Indow Windows. Ideal for
light sleepers, night-shift workers, newborns and home theater
audiophiles. Available in Standard and Acoustic Grades.
d. Commercial Grade (CG) Have an extra abrasion resistant coating
to provide additional protection against scratching (moving
and frequent cleaning). There is no visual difference between the
Standard, Museum and Commercial Grade acrylic.
e. Museum Grade (MG) Protects furniture, carpets, and artwork by
filtering 98% of all UV rays from sunlight coming through
windows. There is no visual difference between the Standard,
Museum and Commercial Grade acrylic.
f. Privacy Grade (PG) Translucent white acrylic diffuses light
transmission while blocking details and defined shadows.
g. Shade Grade (SG) Reduces the heat and damaging UV rays
coming through the window while maintaining a high level of
visible light and clarity. Shade Grade reduces the Solar Heat
Gain through the opening by 53% (SHGC of .47) while
maintaining 63% visible light transmittance.
2. Compression Tubing
a. Contains no PolyVinylChloride (PVC)
b. Friction fit Silicone tubing
c. Available in 3 standard colors with custom color matching
available per request.
