Premium entrance doors with the thermal performance to match
A front door should do more than create a great first impression. Thermocore™ by Stellar® combines the strength, security and low-maintenance benefits of aluminium with enhanced thermal performance, helping create more comfortable homes all year round.
Designed to complement modern thermal window and door systems, Thermocore™ features an insulated core construction that helps reduce heat transfer through the entrance door while maintaining the clean architectural styling and durability aluminium is known for.
Whether you're building new or upgrading an existing home, Thermocore™ offers a stylish and practical solution for projects where thermal performance matters.
Why choose Thermocore™?
An insulated core helps reduce heat transfer through the entrance door, supporting improved thermal performance throughout the home.
Aluminium construction delivers excellent strength, security and long-term durability.
Enhanced thermal performance can help minimise the conditions that contribute to condensation compared with standard aluminium entrance doors.
Helps support a warmer, drier home during winter and a cooler indoor environment during summer by reducing unwanted heat loss and heat gain.
Unlike timber entrance doors, aluminium will not shrink, split or warp, helping maintain weathertight performance and appearance over time.
Designed and engineered locally to suit New Zealand's diverse climates and building requirements.
Thermally enhanced construction
At the heart of Thermocore™ is an insulated polyurethane core designed to improve thermal performance while retaining the strength and durability of aluminium construction.
The result is an entrance door that works seamlessly alongside modern thermal joinery systems, helping create a more consistent thermal barrier around the home.
Thermocore™ has a calculated panel R-value* of 0.63.
* R-Value based on a calculated non-glazed panel per square metre. Actual thermal performance may vary depending on door size, glazing configuration and other design factors.
Design options
Thermocore™ is available in a range of contemporary panel designs to suit different architectural styles, from minimalist solid-panel designs through to glazed options that introduce natural light into entry spaces.
Available designs include:
Right-hand and left-hand glazing configurations are available where applicable.
