Product Description

A thermal break commercial door utilizes thermal insulation technology to achieve high energy efficiency. Its core design embeds high-strength insulation strips (such as polyamide PA66+GF25) within an aluminum alloy frame, blocking heat transfer between indoor and outdoor spaces while maintaining the strength and durability of the aluminum alloy. Designed specifically for commercial buildings, these doors offer comprehensive insulation, soundproofing, and airtightness, making them suitable for energy-conscious environments.

1. Best Aluminium Doors Data Features

Thermal Conductivity (U-Value)

The U-value of a thermal break commercial door is typically less than 2.5 W/(m²·K), significantly lower than that of standard aluminum alloy doors (U-value ≥ 6.0 W/(m²·K)). For example, models with double-chamber insulation strips and triple-glazed, double-chamber glass can achieve a U-value as low as 1.2 W/(m²·K), approaching Passive House standards and significantly reducing air conditioning and heating energy consumption.

Airtightness

Meets the GB/T 7106-2019 standard for Level 8 airtightness, meaning leakage per unit length is ≤0.5 m³/(m·h) at a pressure differential of 10 Pa. This performance effectively blocks the intrusion of outdoor dust and moisture, maintaining a stable indoor environment.

Watertightness

Water pressure resistance reaches Level 6 (≥700 Pa), equivalent to withstanding heavy rainfall without leakage. The sealing structure utilizes EPDM rubber strips, which offer excellent aging resistance and a service life of over 15 years.

Soundproofing

The combination of thermal insulation strips and insulating glass achieves a weighted sound insulation (Rw) of 35-40 dB, effectively shielding urban traffic noise (approximately 70 dB) to below 35 dB indoors, meeting the quiet requirements of offices, hotels, and other spaces.

Wind Pressure Resistance

The structural strength reaches Level 9 (≥5.0kPa), capable of withstanding the positive and negative pressure differentials generated by a Level 12 typhoon (wind speed ≥32.7m/s), making it suitable for high-rise buildings or coastal areas.

2. Aluminum Doors Structural Types

Multi-Cavity Thermal Bridge Structure

The aluminum alloy profile features multiple independent chambers. Insulation strips physically separate the inner and outer profiles, creating a "cold bridge" barrier. For example, a 65mm wide profile with a 24mm wide insulation strip inside creates a three-chamber structure, reducing heat loss by over 60%.

Composite Profile Structure

A wood grain transfer layer or PVC decorative panel is applied to the aluminum alloy surface, achieving both aesthetics and thermal insulation. For example, with an aluminum exterior and wood interior structure, the wood layer further reduces the risk of condensation on the interior side, making it suitable for high-end commercial spaces.

Modular Combination Structure

Supports a variety of door configurations, including single-leaf, double-leaf, floor-spring, and automatic sensor doors. Modules such as ventilation shutters and emergency exit systems can also be integrated. For example, floor spring doors feature concealed hinges and a thermal break design, accommodating pedestrian traffic while maintaining continuous insulation.

3. Advantages

Significant Energy Savings and Consumption Reductions

For a 100-square-meter door, thermal break commercial doors can reduce heating energy consumption by approximately 1,200 kWh annually (based on the northern heating season) compared to conventional doors, equivalent to a reduction of 800 kg in carbon emissions. These doors meet LEED and green building standards.

Improved Comfort

The thermal insulation eliminates condensation indoors, preventing condensation and mildew caused by temperature differences, and maintaining a dry indoor environment. Furthermore, the sound insulation reduces noise disturbance, enhancing the office or living experience.

Durability and Low Maintenance

The aluminum alloy surface is anodized or fluorocarbon-coated, achieving corrosion resistance that meets AAMA 2605 standards and exhibits no noticeable fading or deformation for 20 years. The thermal insulation strips are UV-resistant and will not embrittle over time.

Design Flexibility

The full RAL color palette is available, allowing for customizable finishes such as wood grain and brushed metal to complement various architectural styles. Furthermore, the modular design of the profiles allows for future upgrades to smart locks, sensors, and other accessories.

4. Application Scenarios

High-end Retail and Commercial Complexes

Main entrances and luxury storefronts utilize thermally insulated Aluminum Commercial Doors, providing transparent display of merchandise while also reducing air conditioning load and operating costs through thermally insulated glass and low-emissivity (Low-E) coatings.

Office and Hotel Buildings

Lobby automatic sensor doors and conference room partition doors utilize thermally insulated structures, combined with intelligent control systems (such as facial recognition and mobile app control), to enhance security and convenience while meeting the energy-saving requirements of star-rated hotels.

Medical and Educational Facilities

Hospital outpatient departments and school classroom doors require strict control of indoor temperature, humidity, and noise levels. Thermally insulated commercial doors, combined with antimicrobial coatings and sealing designs, create a healthy and quiet environment.

Industrial and Cold Chain Logistics

Cold storage doors and cleanroom doors utilize reinforced thermally insulated structures and low-temperature sealing strips to maintain stable performance in temperatures ranging from -30°C to +50°C, minimizing cooling loss. Passive House

This thermally insulated commercial door, which complies with the Passive House standard (PHPP certification), achieves zero-energy building goals through its ultra-low U-value (≤0.8W/(m²·K)) and airtight design. It is suitable for high-latitude regions such as Northern Europe and Canada.
