Architectural window film
LUNOX manufactures architectural window film in Gyeonggi-do, Korea — sputter, ceramic, safety, reflective, and decorative films for commercial curtain wall, high-rise retrofit, storefront glazing, and signature buildings. Specified for the 555 m Lotte World Tower and 30+ tier-1 Seoul office buildings.
Architectural film vs automotive tint
Architectural window film is a different product category from automotive tint, even when the marketing sometimes conflates them. Architectural film uses thicker PET substrate (2 mil vs 1.5 mil), adhesive chemistry calibrated for lifecycle installation on glass held in aluminum mullions, and warranty terms that reflect the multi-decade building lifecycle. LUNOX runs both product categories on the same production floor under one quality-management system, but with distinct SKU catalogs.
The architectural chemistries LUNOX manufactures
| Chemistry | Where it wins | Signature spec |
|---|---|---|
| Sputter | West / south elevation tall buildings · maximum IR rejection · signature projects | TSER up to 67%, reflects heat at glass face |
| Ceramic | Signal-sensitive tenants · offices with embedded antennas · hospitals | TSER up to 82.5%, metallic-free (no signal attenuation) |
| Safety / Security | Government · retail · banking · schools · residential impact protection | 11 SKUs, 2 mil to 12 mil, ballistic-rated available |
| Reflective | Daytime one-way privacy · commercial storefront · residential privacy retrofit | Mirror finish exterior, neutral interior |
| Decorative / Matte | Interior partition glazing · conference rooms · design-forward projects | Frosted, patterned, gradient finishes |
Why architectural film pays back on tall buildings
On the west and south elevations of a tall commercial building, solar load is punishing year-round. Post-occupancy data on tall-glass projects shows 25–35% cooling-load reduction on treated elevations vs untreated control areas — the HVAC energy savings over even 10 years dwarf the film installation cost. Over a 30-year building lifecycle, the differential is 7-figure HVAC cost.

Installation and certification requirements
Architectural sputter installation at scale (10,000 m²+ curtain wall) requires certified installers. Sputter's high solar absorptance changes the thermal profile of the glazing unit — installation on the wrong glass type without thermal-stress analysis can cause glazing failure. LUNOX certifies installer partners globally and travels the QC team to site for the first 10–15% of installation on major projects to lock in technique.

What buyers typically ask next
What defines architectural window film vs automotive tint?
Architectural window film is engineered for building-scale glazing — curtain wall, commercial storefront, high-rise retrofit, atrium glazing. Substrate PET is typically thicker (2 mil vs 1.5 mil automotive), adhesive chemistry is calibrated for lifecycle installation on glass held in aluminum mullions rather than a rubber-gasketed car window, and warranty terms run 10 years (vs 5 for automotive) reflecting the multi-decade building lifecycle.
Which chemistries matter for commercial architectural work?
Sputter for west and south elevations where solar load is worst and cooling-load reduction pays back over the building lifecycle. Ceramic for signal-sensitive tenants (embedded antennas, cellular equipment). Safety and security film for government, retail, and banking. Reflective for daytime privacy. Decorative and matte for interior partition glazing and design-forward projects.
What certifications should an architectural spec require?
ISO 9001 on production, TÜV Rheinland or NFRC third-party spec verification on the finished film (VLT, SHGC, U-value, TSER), RoHS environmental conformity, and Certificate of Analysis per production batch. For safety film specifications: ASTM D 3652 (thickness), D 882 (tensile), D 3330 (peel adhesion), GSA bomb-blast test cert for ballistic-rated films.
How does architectural film pay back on tall buildings?
Post-occupancy data on similar tall-glass projects shows 25–35% cooling-load reduction on treated west/south elevations vs untreated control areas. Over a 30-year building lifecycle, that's a 7-figure HVAC cost differential. See the sputter HVAC energy savings guide for the ROI math on typical commercial curtain-wall retrofit scenarios.
What's the MOQ for architectural film OEM programs?
500 rolls for a first order; 2,000 rolls for distributor pricing tier; 2,000 rolls per SKU for custom-spec runs. Roll size 152 cm × 30 m (60-inch × 100-foot) is architectural standard. Custom widths from 90 cm to 183 cm available on OEM programs. Custom-cut lengths for specific glazing dimensions available on 2,000-roll+ commercial contracts.
Does LUNOX certify installers for architectural sputter projects?
Yes. Architectural sputter installation at scale (10,000 m²+ curtain wall) requires installer certification — LUNOX certifies installer partners globally and travels the QC team to site for the first 10–15% of installation on major projects to lock in the technique. Installer certification list per country available via the Inquiry form.
Which architectural warranties come with LUNOX film?
10-year color-stability and structural-integrity warranty on sputter, ceramic, and reflective architectural lines. 10-year film-integrity warranty on safety and security lines (with test-rated ballistic performance held for the film thickness spec). Warranties are issued in the OEM partner's name for private-label programs; LUNOX backs coverage as manufacturer of record.
What projects has LUNOX architectural film been specified for?
555 m Lotte World Tower curtain wall (Seoul, world's 6th tallest), Incheon International Airport Terminals 1 and 2, and 30+ tier-1 office buildings across Seoul — typically retrofit projects for energy-code compliance. Full case: see the Lotte World Tower architectural retrofit guide.
