What are internally embedded aluminium frames?

Internally embedded aluminium frames are glazing systems designed so the aluminium sits within the internal wall structure rather than exposed to the interior.
Instead of stopping at the wall surface like traditional or thermally broken frames, the internal edge of the frame is recessed into the plasterboard, timber lining, or joinery.

This refined construction:

  • Minimises the amount of visible aluminium
  • Creates a cleaner, more contemporary wall-to-glazing transition
  • Aligns the frame more closely with the wall’s insulation layer

With insulation and linings running right up to the frame, thermal continuity is significantly improved, reducing heat transfer at key junctions. Systems such as AWS ComfortEDGE™ illustrate how rethinking the frame-to-wall connection can dramatically enhance overall efficiency.

Benefits of internally embedded frames



Superior Thermal Performance

By sitting within the insulated wall zone, the frame is better protected from internal and external temperature swings.

This limits heat gain in summer, reduces heat loss in winter, and strengthens the building envelope.



Minimalist sightlines & architectural clarity

Embedding the frame removes the need for bulky reveals—allowing interior finishes to meet the glass cleanly and consistently.
The result is a sleek, almost frameless aesthetic with:

  • Less visual clutter
  • More natural light
  • Stronger connection to views



Comfort, Efficiency & Long-Term Value

Better thermal performance equals better living.

Lower energy consumption over the building’s lifetime improves comfort year-round, while reducing operational costs and supporting sustainable building outcomes.

What is a thermal break?

Aluminium is durable, long-lasting, and strong—but it also conducts heat very efficiently.

A thermal break solves this by inserting a high-performance insulating barrier (typically a polyamide strip) between the internal and external aluminium components of the frame.

This barrier:

  • Stops heat and cold from passing through the metal
  • Helps maintain more consistent indoor temperatures
  • Enhances the overall energy rating of the window or door

ThermalHEART™ – Taking Efficiency Even Further

ThermalHEART™ systems represent one of the highest-performing thermally broken aluminium solutions available in Australia. They are engineered to make a measurable difference:

  • Up to 51% more thermally efficient than standard aluminium frames
  • Polyamide insulation integrated into the frame for exceptional thermal resistance
  • Structural integrity maintained, thanks to aluminium and polyamide expanding at similar rates

ThermalHEART™ creates a stronger barrier between inside and outside, keeping warm air indoors in winter and blocking heat in summer. It’s a proven way to reduce reliance on air conditioning and improve overall energy efficiency.

Advantages of thermal break systems



Higher Energy Efficiency

ThermalHEART™ dramatically reduces thermal bridging and delivers superior insulation performance.



Lower Heating & Cooling Costs

With less energy needed to stabilise internal temperatures, homeowners can enjoy reduced energy bills year-round.



Dual colour finish option

Dual-colour options allow you to choose different internal and external finishes—perfect for tailoring your look both inside and out.
