30.2mm Durable Polyamide Thermal Barrier for Doors

Overview

The 30.2 mm K thermal break profile is designed to significantly improve the energy efficiency of aluminium framing systems. It is widely applied in windows, doors, façades, passive houses, and curtain wall structures. A thermal break functions as an insulated gap within the aluminium frame, interrupting the natural path of heat conduction. By filling this gap with high-performance insulating materials such as polyamide PA66 GF25, the profile enhances both durability and thermal performance. Systems with more thermal breaks achieve lower heat transfer, resulting in superior energy savings, reduced operating costs, and better comfort for building occupants.

Product Features

• Strengthens frame stability – Provides reliable structural reinforcement for aluminium frames during both assembly and long-term operation. The 30.2 mm hollow chamber profile works with precise extrusion tolerances to prevent frame deformation and ensure secure installation, even under frequent use or wind load stress.

• Cuts heat transfer – Forms a continuous insulating layer between the inner and outer aluminium sections, effectively reducing thermal bridging. This design lowers energy consumption by minimizing heating loss in winter and blocking excess heat in summer, helping buildings achieve better energy efficiency ratings.

• Minimizes condensation risk – Interrupts conductive heat flow across aluminium frames, lowering the surface temperature difference that typically causes condensation. This extends the lifespan of the framing system, protects against moisture-related damage, and reduces the maintenance workload for facility operators.

• Delivers consistent comfort – Maintains stable indoor temperatures across seasonal changes by controlling both heat loss and heat gain. Occupants benefit from year-round comfort in residential or commercial environments, while system owners gain assurance that installations comply with modern energy-efficiency regulations.

Product Advantages

• Predictable U-factor gains – Provides reliable and measurable thermal performance improvements for slim and standard aluminium systems. This helps projects reach energy-efficiency targets and qualify for global green building certifications without redesigning the entire frame system.

• Coats after assembly – Withstands coating temperatures up to 200 °C, making it possible to finish frames after thermal strips are installed. This supports dual-color or two-tone surface options, streamlines production steps, and reduces material handling costs during manufacturing.

• Low air/water leakage – Produced with strict extrusion tolerances that enhance airtightness and watertightness at connection points. This minimizes drafts, leakage, and long-term weathering risks, ensuring aluminium windows and doors maintain indoor comfort and reduce maintenance needs.

• Short lead time – Standard delivery within 7–15 days ensures timely supply for manufacturers and contractors. This fast turnaround supports on-site project scheduling, minimizes delays, and provides flexibility in managing both small-scale and large-scale construction demands.

Product Applications

• Thermally broken aluminium windows/doors – Designed for residential and light commercial buildings that require higher energy efficiency. By integrating thermal break strips, these systems cut heating and cooling costs, improve acoustic insulation, and create comfortable interior spaces that meet modern building standards.

• Narrow-profile façade modules and mullions – Well suited for slim architectural frames where aesthetics and insulation must work together. The hollow chamber thermal break maintains sleek sightlines while reducing thermal bridging, allowing façades to achieve energy savings without compromising on design freedom.

• Retrofit sash upgrades – An effective choice for renovation projects with limited frame depth. The 30.2 mm profile introduces a compact thermal barrier that boosts insulation and reduces condensation risk, enabling energy-efficient upgrades without replacing the entire aluminium system.
