SpanishVexis Windows & Doors Co., Ltd. is an industry-leading Chinese manufacturer specializing in the structural design, precision extruding, thermal break processing, glass fabrication, and international export of premium Aluminum Sunrooms, winter gardens, and architectural glass enclosures. Operating from our state-of-the-art industrial hub in Lishui Town, Foshan, Guangdong, China, we combine 20+ years of export engineering with advanced structural physics to serve commercial real estate developers, window importers, general contractors, and architectural firms across North America, Europe, Australia, and the Middle East.
In modern architectural engineering, an aluminum sunroom is far more than an assembly of glass sheets and frames; it is a fully integrated building envelope structure that must withstand extreme thermal differentials, severe wind uplifts, snow loads, solar radiation, and torrential rainfall. Unlike local resellers or uncertified fabrication workshops, Vexis Windows & Doors Co., Ltd. manages the entire manufacturing chain in-house. Our engineering team designs custom structural extrusions featuring high-tensile 6063-T5/T6 primary aluminum alloys, reinforced PA66-GF25 polyamide thermal break strips, and multi-layer EPDM vulcanized sealing gaskets that meet or exceed rigorous international building standards including AS2047, ASTM E330, NFRC, and European CE specifications.
Whether you require prefabricated Knock-Down (KD) sunroom kits for residential housing developments, heavy-duty span winter gardens for luxury hotels, or motorized bioclimatic glass roofs for commercial rooftop venues, Vexis delivers factory-direct wholesale pricing backed by comprehensive CAD/BIM shop drawings, FEA structural calculations, and zero-defect quality control inspections.
A technical analysis of structural durability, thermal insulation physics, water management, and lifetime maintenance compared to traditional steel or wood glass additions.
Unlike standard architectural aluminum profiles that use thin 1.4mm walls, Vexis aluminum sunrooms feature heavy-gauge load-bearing pillars, rafters, and ridge beams with profile wall thicknesses ranging from 3.0mm to 5.0mm. Engineered from 6063-T6 primary aluminum billets, our structural profiles deliver yield strengths exceeding 210 MPa, allowing wide-span clear glass roofs without requiring unsightly steel support columns inside the living space.
Aluminum is naturally highly conductive. To prevent thermal bridging that causes severe winter heat loss, summer heat gain, and interior frame sweating, Vexis embeds 24mm to 34mm wide PA66-GF25 (25% glass fiber reinforced polyamide) thermal break strips into all main profiles. This structural break reduces overall sunroom roof frame thermal conductivity (Uf) to below 1.6 W/m²K, turning a glass house into an energy-efficient year-round living area.
The leading cause of sunroom failure in global field installations is water leakage due to degraded silicone caulking. Vexis eliminates external silicone dependence by engineering a patented internal multi-stage water gutter system. Integrated internal channels inside the roof rafters collect condensation and rainwater seepage, directing it through hidden structural downspouts built within the vertical posts.
Overheating and UV damage are common issues in cheap sunrooms. Vexis specifies high-performance double or triple insulated glass units (IGUs) incorporating tempered laminated safety glass (e.g., 6mm Low-E + 12Ar + 6mm Toughened Laminated 5+1.14PVB+5). This configuration reflects up to 78% of infrared solar radiation, absorbs 99% of UV rays, and guarantees roof glass safety under heavy snow or falling hail impact.
For seaside villas, tropical coastal resorts, or industrial urban sites, frame corrosion is a critical concern. Vexis sunrooms undergo an automated multi-stage pre-treatment phase before applying AkzoNobel or PPG PVDF (Polyvinylidene Fluoride) fluorocarbon coatings. Rated for 20+ years of color retention under intense UV and salt-spray conditions (tested to AAMA 2605 specifications), your sunroom frames will not fade, chalk, or corrode.
A complete Vexis sunroom seamlessly integrates our high-performance thermal break sliding doors, bifold doors, tilt-and-turn windows, and skylights directly into the main roof and wall extrusions. This systemized approach guarantees perfect structural fit, continuous EPDM weather sealing, and uniform thermal efficiency across all opening components.
Explore our core factory-manufactured sunroom engineering lines designed for luxury residential extensions, commercial hospitality venues, and multi-family housing projects.
Designed with a classic cathedral vaulted peak, the Gable Roof Aluminum Sunroom offers maximum interior headroom, architectural grandeur, and superior snow shedding capacity. Ideal for four-season room extensions in cold northern climates like Canada, North USA, and Northern Europe.
The single slope lean-to glass enclosure is the most versatile and cost-effective structural system for patio enclosures, balcony conversions, and villa wall extensions. Features seamless roof flashing integrated into existing masonry walls for 100% weatherproofing.
Combining elegant smooth curved glass roof transitions with rigid extruded aluminum rafters, the curved eave sunroom offers panoramic sky views without structural roof obstruction. Widely specified in high-end coastal estates and residential garden rooms.
Transform your space instantly from an enclosed indoor sanctuary to an open-air outdoor terrace with Somfy-powered motorized sliding glass roof modules. Perfect for luxury restaurant patios, hotel swimming pool enclosures, and private rooftop lounges.
Engineered for commercial spaces requiring spans exceeding 8 meters without intermediate vertical column obstructions. Vexis structural engineers utilize steel-reinforced internal core profiles within aluminum sleeves to deliver immense strength and clean visual lines.
Designed for contemporary architectural aesthetics, this system minimizes visible aluminum frame sightlines (interlock narrowness of 20mm) while maximizing floor-to-ceiling structural glass transparency. Seamlessly paired with flush-threshold sliding glass doors.
How evolving net-zero energy building codes, smart home automation, and modular off-site manufacturing are shaping international B2B sunroom specifications through 2030.
Procurement Shift: Skyrocketing on-site construction labor costs in Australia, Europe, and North America have made traditional welded or custom-fitted field sunroom assembly economically unviable. International buyers now mandate 100% pre-engineered, CNC-machined KD sunroom kits.
Vexis Engineering Solution: All Vexis aluminum sunrooms undergo full 3D pre-assembly inside our Foshan factory. Connectors are pre-drilled, gaskets pre-fitted, and structural joints milled with high-precision CNC equipment. Field installation requires no cutting or welding—slashing site labor time by up to 60%.
Development Trend: Modern sunrooms are transitioning from static structural glass shells into intelligent bioclimatic microclimates connected to Tuya, Somfy, or Control4 smart home ecosystems.
Vexis Technical Feature: We offer fully integrated motorized thermal roof blinds, smart solar glass with electrochromic tinting, motorized rain-sensing roof skylights, and concealed LED perimeter strip lighting operated via mobile apps or voice automation.
Code Evolution: Strict energy conservation directives (such as the EU Energy Performance of Buildings Directive and California Title 24) require sunroom envelopes to match the thermal efficiency of insulated masonry walls.
Vexis Material Innovation: By integrating multi-chambered 6063-T6 thermal profiles with Aerogel insulation infills and warm-edge spacer triple glazing, Vexis sunrooms achieve whole-structure U-values down to 0.98 W/m²K, making four-season sunrooms feasible in sub-zero subarctic environments.
Market Demand: Importers in tropical typhoon zones (e.g., Caribbean, Philippines, Florida, Coastal Australia) require verifiable structural engineering data certifying resistance against high winds, airborne debris impact, and torrential rain.
Vexis Testing Compliance: Our heavy-duty aluminum sunroom roof systems are FEA stress-tested to resist wind uplift pressures exceeding 5,000 Pa (equivalent to Category 5 hurricane wind speeds) and snow load capacities of over 2.5 kN/m².
