PVC — IGLO Series
IGLO ENERGY CLASSIC
7-chamber Class A platform with the optional angular glazing bead aesthetic. Uw = 0.73 W/(m²K). Three factory standard colors. The 7-chamber thermal range with a modern square-edge sightline.
- 0.73 W/(m²K) Uw
- Class A Profile (EN 12608)
- 7 Chambers
- 82 mm Build depth
- Angular Glazing bead
- 3 colors Factory standard
Why spec this one
IGLO ENERGY CLASSIC is the option for projects that want 7-chamber thermal performance but need:
- The angular glazing bead aesthetic. A square-edge glazing bead reads cleaner on modern architectural details; the standard rounded bead on IGLO ENERGY reads softer. Same frame, different visual at the glass-to-frame intersection.
- Three factory standard colors. White, anthracite, brown all available as factory PVC — anthracite without going through Renolit foil.
- A balanced spec. Uw of 0.73 sits between IGLO EDGE (0.66) and the 5-chamber IGLO 5 (0.89). For most premium residential, this is the right thermal tier without paying for IGLO EDGE performance you won’t fully use.
Standard equipment
- Double-chamber triple-pane IGU at Ug = 0.5 W/(m²K)
- Swisspacer Ultimate warm-edge spacer (free option)
- V-Perfect weld corner
- 4 anti-burglary engagement points
- Microventilation
- Aluminum window handle
- Sash position blocker
- Perimeter, glazing, and central EPDM seals in black or grey
- Hardware groove sealing
- Sub-sill drip cap profile

Full technical detail
IGLO ENERGY CLASSIC is a 7-chamber Class A PVC tilt-turn window system built on the 82 mm depth profile platform shared with IGLO EDGE and IGLO ENERGY. It differentiates from IGLO ENERGY through two features: the availability of three factory-standard PVC colors (white, anthracite, brown) and the optional angular square-edge glazing bead at the glass-to-frame interface.
Thermal performance of Uw = 0.73 W/(m²K) is achieved through the 7-chamber frame geometry, the standard double-chamber triple-pane IGU at Ug = 0.5 W/(m²K), the Swisspacer Ultimate warm-edge spacer (free upgrade), and the triple EPDM gasket sealing including the foamed central gasket. The thermal number sits between IGLO EDGE (0.66) and the 5-chamber IGLO 5 (0.89), a balanced specification for most premium residential.
Acoustic insulation ranges from 36 dB to 42 dB depending on glazing. Standard hardware is MACO MULTI-MATIC KS with Silber-Look anti-corrosion coating, 4 anti-burglary engagement points, and sash position blocker; aluminum handle standard, with Smart Home electronic handle upgrades available. Color options include three factory-standard PVC colors plus the full Renolit foil range — the factory-standard anthracite is the key differentiator from IGLO ENERGY, which provides anthracite only through foil.
Operation types include tilt-turn, fixed, tilt-only, side-hung, and top-hung; custom geometric shapes supported. Application range is residential new build and replacement, multi-family, and light commercial across the Northeast US climate envelope. NFRC-equivalent thermal data, wind load, and water tightness ratings available for code compliance submission.

Selected finish:
Where it fits
Spec it for
- Modern residential where the angular glazing bead is part of the architectural language
- Premium residential where 7-chamber thermal is needed and three standard colors matter
- Multi-family premium tier where mixed color specs across the project are common
- Projects that want the modern look without committing to the IGLO EDGE upcharge
Don't spec it for
- Projects requiring Uw < 0.7 (use IGLO EDGE)
- Coastal or storm-exposed sites where IGLO ENERGY’s air infiltration ratings matter more
- Outward-opening applications (use IGLO EXT or IGLO PREMIER)
