Direct factory supply of fusion-welded uPVC and thermal-break aluminum fenestration systems designed to meet ABNT NBR 10821 structural and energy standards.
The Brazilian architectural sector is experiencing a paradigm shift toward high-performance envelope engineering. Driven by expanding luxury residential construction in regional hubs such as São Paulo (Alphaville, Jardins), coastal developments along Santa Catarina (Balneário Camboriú), and premium resort hospitality in the Northeast (Bahia, Ceará), demand for structural opening systems has moved beyond standard sliding doors toward grand entrance portals.
Among these, Double French Swing Doors with Sidelights have emerged as the specification of choice for architects seeking grand visual symmetry, maximum clear opening width, and seamless indoor-outdoor transitions. However, sourcing these complex fenestration assemblies for the Brazil market requires solving acute engineering challenges: extreme UV exposure, saline corrosion in coastal zones (salt fog resilience), torrential tropical rainfall, and strict structural compliance under ABNT NBR 10821 (Performance of External Doors and Windows).
Engineered with internal heavy-gauge galvanized steel reinforcements within the fusion-welded profile chambers to withstand positive and negative pressure loads exceeding 2000 Pa in coastal Brazilian high-rises.
Utilizes advanced double-pane insulating glass integrated with LoĒ³-366 triple-silver low-E coatings and argon gas fill, reducing Solar Heat Gain Coefficient (SHGC) down to 0.22 while preserving clear visible light transmission.
Formulated with 100% virgin uPVC vinyl profiles titanium dioxide (TiO2) stabilization or marine-grade anodized/powder-coated aluminum profiles that will not pit, peel, or rust under intense Atlantic ocean air exposure.
Selecting the right door substrate for Brazilian microclimates requires evaluating long-term degradation vectors against structural integrity.
| Performance Criterion | Amar Fusion-Welded Virgin Vinyl | Thermal Break Aluminum | Traditional Brazilian Hardwood |
|---|---|---|---|
| Thermal Conductivity (U-Factor) | 0.27 – 0.30 W/m²K (Superior Thermal Barrier) | 0.35 – 0.42 W/m²K (Good with Insulated Thermal Strip) | 0.45 – 0.55 W/m²K (Moderate, structural shifting distorts seals) |
| Salt Spray & Coastal Humidity Resistance | Immune (No oxidation, zero chalking or surface pitting) | High (Requires Qualicoat Class 2 finish in coastal zones) | Low (Rapid expansion, fungal rot, requires annual refinishing) |
| Corner Joint Structural Integrity | Monolithic Fusion-Welded Corners (Zero Leak Joints) | Mechanically Crimped / Cleated with Silicone Gaskets | Mortise & Tenon with Adhesive (Prone to sagging & gap opening) |
| Air Infiltration Rating (ASTM E283) | < 0.04 cfm/ft² (Dual EPDM Continuous Weatherstripping) | < 0.08 cfm/ft² | > 0.20 cfm/ft² (Deteriorates as wood warps) |
| Maintenance Overhead | Zero Maintenance (Simple water clean, built-in color) | Low (Occasional rinse and hardware lubrication) | High (Constant sanding, varnishing, anti-termite treatment) |
A primary failure point in traditional double French swing door installations with sidelights is frame flexure at the mullion junction. Amar solves this through integrated steel-reinforced structural mullion couplings.
The sidelights are not merely butt-jointed to the swing door jambs; they are interlocked using high-tensile internal connector keys and continuous vinyl snap-covers. This ensures uniform wind-load redistribution across the entire rough opening width, preventing sash binding or frame distortion even under severe gust conditions in high-altitude residences in Campos do Jordão or beachfront towers in Florianópolis.
Security and weather-tightness are inseparable in large swing door portals. Our factory fits all Double French Swing Doors with German-engineered, heavy-duty multi-point locking systems.
When the active door leaf is engaged, continuous shoot-bolts project into top and bottom frame keepers while multiple cam-locks pull the sash tight against dual EPDM bulb gaskets. This creates an airtight seal that eliminates water intrusion during heavy Brazilian winter rains and provides formidable resistance against forced entry.
Brazil’s diverse regional climates demand specialized fenestration configurations. Our factory customizes frame profiles, glass build-ups, and hardware finishes to match local architectural blueprints.
Locations: São Paulo, Campinas, Belo Horizonte, Rio de Janeiro.
Design Priority: Acoustic attenuation paired with grand aesthetics. Double French Swing Doors with matching operable or fixed sidelights connect grand living areas to outdoor verandas (varandas gourmet). Configured with 6mm + 12Ar + 6mm acoustic laminated glass to block urban ambient noise.
Locations: Salvador, Recife, Fortaleza, Trancoso.
Design Priority: Maximum solar control and extreme corrosion defense. Formulated with UV-stabilized virgin vinyl and 316-grade stainless steel hardware. Paired with obscure privacy glass or LoĒ³-366 tinted glazing to eliminate heat gain and protect interior furniture from harsh tropical radiation.
Locations: Curitiba, Gramado, Bento Gonçalves.
Design Priority: Thermal retention and zero draft penetration. Winter temperatures in southern Brazil require airtight seals. Our fusion-welded frame geometry with warm-edge spacers retains internal home heating, preventing cold spot condensation along glass edges.
As a vertically integrated fenestration manufacturer, Amar Engineered Products controls every step from raw PVC resin extrusion and alloy formulation to automated glass insulating and container palletization.
We do not assemble bought-out white-label profiles. We own our extrusion dies, maintaining ultra-strict wall thickness tolerances and profile wall geometry. This guarantees exact alignment when coupling sidelights with French swing door frames, eliminating uneven sightlines or joint gaps on-site.
Standard off-the-shelf doors force Brazilian builders to modify rough structural masonry openings with costly fillers and extra plasterwork. Every unit in our factory is custom-fabricated to exact schedule call sizes in 1/8-inch (3mm) increments, saving significant jobsite labor and ensuring a precision fit.
Our commitment to quality is backed by a written limited lifetime warranty covering vinyl extrusion profiles, welded joints, hardware functionality, and insulating glass unit seals against stress cracks and moisture ingress. Real estate developers can hand this warranty straight to property buyers.
Exporting to Brazil requires flawless documentation and protective packaging to navigate customs at Port of Santos, Paranaguá, or Rio de Janeiro. Every unit is individually wrapped in protective film, corner-shielded, and crated in heavy-duty ocean-freight pallets to prevent shipping damage.
Essential guidance for Brazilian real estate developers, window importers, general contractors, and architectural specifiers.
