Our thermal break aluminum alloy sunrooms are widely exported to Europe and North America and are recognized for their energy efficiency, structural stability, and modern appearance. We sincerely look forward to building a long-term partnership and becoming your trusted supplier in China.

Applications & Living Scenarios

Designed for outdoor-to-indoor transition spaces, our thermal break aluminum alloy sunrooms are ideal for:

Private villas and terrace extensions

Rooftop gardens and penthouse spaces

Courtyards and backyard leisure areas

Tea rooms, lounges, and multi-functional sunspaces

The sunroom creates a bright, transparent environment while maintaining excellent thermal performance, allowing comfortable year-round use . It is an ideal solution for high-end residential projects and leisure space upgrades that balance aesthetics, comfort, and practicality .

Key Performance Advantages

Excellent Thermal Insulation
The thermal break structure combines 6063-T5 aluminum profiles with PA66 GF25 nylon thermal break strips , effectively blocking heat transfer. Compared with conventional aluminum sunrooms, indoor temperature differences can be reduced by 5–8°C , significantly lowering cooling and heating energy consumption.

All-Weather Durability
The aluminum frame is treated with anodizing or powder coating, offering strong resistance to corrosion, UV exposure, rain, snow, and extreme temperatures, with a service life of over 30 years  for outdoor use.

Sealing & Noise Reduction
Double sealing systems combined with insulated tempered glass improve thermal performance while effectively reducing outdoor noise, creating a quieter and more comfortable interior space.

Structure & Design

The sunroom adopts a thermal break aluminum frame + insulated tempered glass  structure. The frame consists of columns, beams, and diagonal supports, assembled through a modular system that supports multiple roof styles, including gable roofs, flat roofs, and curved roofs .

The thermal break design separates the inner and outer aluminum profiles, with a PA66 nylon insulation strip embedded between them to fundamentally block heat conduction.

Design features include:

Sliding or hinged glass doors for easy access and ventilation

Hidden drainage channels integrated into the frame to prevent water leakage

Double-sealed insulated glass to reduce condensation and fogging

Optional accessories such as sunshades, electric skylights, and ventilation systems

This combination ensures both functional performance and architectural aesthetics.

Manufacturing Details

High-precision CNC equipment is used throughout the production process. Cutting and jointing tolerances of thermal break aluminum profiles are controlled within ±0.3 mm , ensuring tight connections and structural integrity.

Thermal insulation strips are assembled using a strip-insertion process , combined with high-strength corner adhesives to enhance stability, insulation, and sealing performance, effectively preventing air or water leakage.

Surface treatments include anodizing, powder coating, and fluorocarbon coating. Custom colors such as matte gray, champagne gold, and antique bronze are available. The coatings offer strong adhesion and long-lasting color stability.

Insulated glass units feature double sealing and are filled with desiccant gas to prevent condensation, while dedicated glazing beads enhance overall sealing and safety.

Avoid scratching surfaces or glass with sharp objects; replace cracked glass promptly.

Regularly inspect electric skylights and sunshade systems to ensure smooth operation.

Frequently Asked Questions

Q: Will the thermal break strips in a thermal break aluminum alloy sunroom age and fall off?

A: We adopt PA66GF25 reinforced nylon thermal break strips, which are high temperature resistant and anti-aging. They will not fall off during normal use for more than 20 years and maintain stable performance.

Q: Can Low-E insulating glass be customized to enhance thermal insulation?

A: Customization of Low-E insulating glass is available, which can further reduce the heat transfer coefficient and deliver superior thermal insulation and sun protection effects. The additional cost is about 80 RMB per square meter.
