Overview
What makes the Strongline
stand out.
Strongline is built for performance - a 92 mm frame depth with 3 seal lines and a double drip cap delivers the best weather protection in the timber range. Structural grooves in the multi-layer laminated profile provide layered defense against rain, wind, and noise. The Master variant adds an aluminum protective guard on the outer sash edge for UV and rain shielding. The Retro variant features decorative relief milling for a refined traditional look. AQUATOP finish with cold pigments is specifically designed for hot climates - a detail that matters for sun-exposed facades in Texas, Florida, and the Southwest.
Key Highlights
- Deepest timber profile at 92 mm with 3 seal lines
- Double drip cap with structural grooves for layered weather protection
- Master variant: aluminum sash guard protects wood from UV and rain
- Retro variant: decorative relief milling on sash and glazing bead
- AQUATOP varnish with cold pigments - ideal for sun-exposed facades
- Optional burglar resistance and enhanced acoustic upgrades
Ideal For
High-performance timber builds, energy-efficient homes in cold climates, and projects in hot climates where the cold-pigment finish protects against UV degradation. The Master variant is ideal for exposed locations. Also excellent for noise-sensitive sites near highways or airports.
Consider an Alternative When
If you want similar thermal performance with zero exterior maintenance, the aluclad Synergic or Passive Classic are the natural upgrades. If budget is the priority and standard insulation is sufficient, the Softline 78 XL covers most residential needs.
