Window Styles & Layouts
Choosing the right window means balancing architectural style with measurable performance.
Your selection should complement the character of your Project while delivering the energy efficiency and structural resilience required for your local climate.
From thermal performance to weather resistance, every environment demands the right level of protection. The more extreme the conditions, the higher the performance standard your windows should meet.
If your project calls for something distinctive, KONIFER offers the flexibility to create tailored window combinations—engineered to align with your design vision while maintaining uncompromising performance.
Colour & Exterior Options
Opt for a clean, timeless profile, or elevate the façade with decorative grille patterns or exterior brickmould options, available on select window series.
A range of hardware styles and finishes is also available across most KONIFER product lines, allowing you to coordinate every detail with precision and consistency.
Interior Grille Designs
Designed to replicate the timeless appearance of true divided lites, they deliver architectural character without added maintenance.
The result is classic detailing, modern performance, and a completely worry-free finish.
Grille Widths
Dividers & Mullions
You achieve classic architectural detail without sacrificing insulation, airtightness, or long-term durability.
For enhanced dimensional depth, Dual Shadow Bars are available in triple-pane configurations. Installed between the glass panes and precisely aligned with the exterior SDL profiles, these interior bars create the visual depth of true divided lites.

Advanced Glazing Systems
The right glazing configuration has the greatest impact on thermal insulation, solar control, and overall comfort.
Different glass options are engineered for different environments.
Before selecting your glazing package, consider your regional climate conditions. Colder climates demand higher insulating performance, advanced Low-E coatings, and optimized gas fills to maximize thermal efficiency and reduce heat loss.
Did you know? ENERGY STAR® certified windows can help reduce energy consumption by up to 16%, improving both comfort and long-term operating costs.
GLASS PERFORMANCE
All published performance data is reported in imperial units and reflects Centre of Glass (C.O.G.) values generated through Vision v4.0 simulation modeling. U-values and R-values are calculated in accordance with ASHRAE winter design conditions.
Please note that overall window performance is influenced by additional factors including frame construction, cladding, profile design, spacer systems, and installation conditions. Complete unit thermal values may vary depending on the selected configuration.
