Aluminum Windows Installation & Replacement | Slim-Frame & Custom Styles

Standard systems can be competitive, while thermally improved architectural lines cost more.

Usually the lowest-cost material category, with many series and option levels.

Specialized fabrication, finishing and installation generally make steel the costliest option.

Aluminum is conductive; whole-window performance depends heavily on thermal-break design.

Multi-chamber PVC frames insulate well; foam-filled designs can improve performance.

Steel is conductive, so modern thermal breaks and high-performance glazing are important.

Quality anodized or baked finishes generally need cleaning rather than repainting.

No painting is normally required; periodic cleaning and hardware care are typical.

Modern coatings are durable but should be inspected, especially in wet or coastal exposure.

Rigid frames and durable finishes provide long service when corrosion exposure is addressed.

Resists moisture and decay, while quality and reinforcement affect long-term stability.

Properly protected steel offers excellent rigidity and a very long potential service life.

High strength-to-weight ratio supports large units and demanding configurations.

Adequate for most residential openings; larger units may use internal reinforcement.

Very high strength supports large glass areas and slender custom profiles.

Extruded metal profiles can deliver narrow frames and expansive glass.

PVC profiles generally need more frame width than stronger metal or fiberglass frames.

Steel's strength creates the narrow profiles associated with premium architectural windows.

Well suited to modern forms with many durable powder-coat and anodized finishes.

Many common colors and styles are available, but premium finish options vary by line.

Excellent for custom industrial, historic and contemporary designs, with a more focused aesthetic.

Does not rot, but coastal salt exposure requires suitable coatings, fasteners and maintenance.

PVC does not rot and performs well around moisture when drainage and installation are correct.

Galvanizing and quality coatings are essential to resist corrosion, especially near salt air.

Hardware and finishes can be serviced; bent or damaged extrusions often need specialist replacement.

Hardware and glass can be serviced, but damaged welded frame sections are difficult to repair.

Skilled metalworkers can repair some sections and finishes, though the work is specialized.

Aluminum is highly recyclable, although primary production has substantial embodied energy.

Long service and energy savings help, but PVC production and end-of-life recycling remain trade-offs.

Long life and high recyclability are benefits, balanced against energy-intensive production.
