Insulated Architectural Precast Concrete
Beauty, durability, and energy performance in one complete wall system
Insulated architectural precast concrete combines beauty, durability, and energy performance in one complete wall system. By integrating continuous insulation between concrete wythes, these panels deliver the clean, high-end appearance of architectural precast while improving thermal efficiency and helping reduce energy loss through the building envelope.
​
At TKL, insulated architectural precast panels are manufactured under controlled plant conditions to ensure consistent quality, finish, dimensional accuracy, and long-term performance. These systems can be produced in a wide range of shapes, colours, textures, reveals, and finishes, making them ideal for commercial, institutional, residential, and mixed-use projects where both appearance and performance matter.
How it works
An insulated precast panel is typically made up of:
-
An exterior architectural concrete wythe
-
A layer of rigid insulation
-
An interior structural or backup concrete wythe
This creates a strong, efficient panelized wall assembly that can provide excellent thermal performance while maintaining the durability and low maintenance benefits of concrete.
Typical insulation
thicknesses and
approximate
R-values
The insulation thickness can be tailored to suit the thermal requirements of the project. Approximate effective insulation values are often based on the insulation material selected, most commonly polyisocyanurate, extruded polystyrene, or expanded polystyrene. Actual assembly performance can vary depending on panel design, connectors, thermal bridging, and project requirements.
Common insulation options
​
1" insulation → approx. R-5 to R-6
1.5" insulation → approx. R-7.5 to R-9
2" insulation → approx. R-10 to R-12
2.5" insulation → approx. R-12.5 to R-15
3" insulation → approx. R-15 to R-18
4" insulation → approx. R-20 to R-24
5" insulation → approx. R-25 to R-30
6" insulation → approx. R-30 to R-36
Benefits of insulated architectural precast
Energy efficiency
Continuous insulation helps improve thermal resistance and reduce heat transfer through the wall assembly.
​
Architectural flexibility
Panels can be customized with a wide variety of finishes, colours, shapes, textures, liners, and reveals.
​
Durability
Precast concrete offers exceptional resistance to weather, impact, moisture, and long-term wear.
​
Quality control
Manufacturing in a controlled plant environment allows for greater consistency and precision than site-built systems.
​
Speed of construction
Panels arrive on site ready for installation, helping accelerate building enclosure and reduce site labour.
​
Low maintenance
Architectural precast is designed for long service life with minimal upkeep.
