Costa Rica's tropical climate — with its high humidity, heavy rainfall, and intense sun — demands building materials that can stand up to the elements while delivering lasting performance. For residential and commercial projects across the country, aluminum windows and doors have become the go-to choice, and for good reason. As a leading casement window manufacturer with a global footprint, ALPES brings premium aluminum window and door systems designed to excel in exactly the kind of conditions Costa Rica presents.
Costa Rica's weather varies dramatically from the tropical Pacific coast to the cooler highlands and the rainforest-drenched Caribbean side. Regardless of region, every property faces common challenges: year-round humidity, intense UV exposure, heavy seasonal rains, and occasional strong winds. Traditional materials like wood struggle with warping, rotting, and termite damage in these conditions — and even steel can corrode over time.
Aluminum solves all of these problems naturally. It does not rust, rot, or attract insects. It maintains its structural integrity through decades of temperature swings and moisture. When paired with thermal break technology — a standard feature across ALPES product lines — aluminum windows also deliver impressive energy efficiency, helping to keep interiors cooler and reducing air conditioning costs, which is especially valuable in warm coastal areas like Guanacaste and Puntarenas.
Casement windows are among the most popular styles for Costa Rican residential projects, thanks to their excellent ventilation control and superior sealing when closed. ALPES offers three outstanding casement window series, each engineered with 6060-T66 grade aluminum profiles and PA66GF25 thermal break strips for optimal thermal performance.
The C120 Outward Opening System Window stands out for its robust 1.8–2.0mm profile thickness and full standard square cavity design, providing superior wind pressure resistance — a critical feature in areas prone to strong breezes or tropical storms. Its nail-free rolled press mesh structure ensures the screen stays flush and corrosion-free for years.
For those who prioritize a sleek, modern look, the C116 Outward-Open Window features a slim 28mm oblique press line and 22mm medium mullion that maximizes the glass area and field of vision. Its triple sealing strips with seamless welded corners deliver exceptional weatherproofing, keeping Costa Rica's heavy rains firmly outside.
As Costa Rica's luxury residential market continues to grow, so does demand for high-performance tilt and turn windows — a European-inspired design that offers two opening modes in one frame. Tilt the sash inward from the top for secure, draft-free ventilation, or swing it fully open like a casement window for maximum airflow and easy cleaning from inside.
The ALPES AW90 Passive Window represents the pinnacle of this technology, achieving a thermal K-value as low as 1.3 — well within passive house standards. Its dual-matrix eight-layer sealing system creates an almost airtight barrier against humidity, noise, and heat transfer. For premium villa projects in areas like Escazú, Santa Ana, or the Papagayo Peninsula, this level of thermal performance translates directly into lower energy bills and year-round comfort.
All AW90 windows come equipped with Winkhaus hardware — a German manufacturer with 169 years of engineering heritage — ensuring smooth, reliable operation even after decades of daily use. The 360° locking point distribution provides full-perimeter security, an important consideration for both ground-floor and upper-level installations.
One of the great joys of living in Costa Rica is the seamless connection between indoor and outdoor spaces. Whether it is a beachfront condo in Tamarindo, a mountain retreat in Monteverde, or a family home in San José, large-format sliding doors are essential for opening living areas to patios, gardens, and pools.
As a trusted sliding door supplier, ALPES offers several heavy-duty sliding door series designed for large openings without sacrificing performance. The SL155 Thermal Break Sliding Door features a four-track 155mm frame and single-panel double-rail self-balancing pulley system with a 20-wheel configuration that can carry up to 400kg per panel. Single sashes can reach up to 2800mm wide by 2600mm high, creating an opening area of up to 7.5 square meters — perfect for panoramic views of Costa Rica's stunning landscapes.
For projects that demand an even slimmer profile, the SL126/182(75) Thermal Break Sliding Door offers a 75mm narrow edge design with a 38mm extreme slim frame option. Its 27A super-large insulating glass with inert gas filling provides excellent thermal and acoustic insulation — ideal for reducing street noise in urban areas or enhancing the tranquility of rainforest settings.
ALPES operates from a 100,000 m² manufacturing facility with two major production centers in Foshan and Zhaoqing, Guangdong — the heart of China's aluminum window and door industry. This scale allows the company to handle projects of any size, from single-home renovations to large-scale residential developments and commercial builds.
For Costa Rican builders, architects, and project developers, working with ALPES means access to factory-direct pricing without sacrificing quality. The company has extensive experience exporting to markets worldwide, including the Middle East and Australia, and understands the logistics and documentation requirements for international shipping to Central America.

From the precision cutting of aluminum profiles to the final assembly and testing, the company maintains strict standards that ensure every window and door that leaves the factory is ready to perform for decades in Costa Rica's demanding environment.
Choosing the right windows and doors for a Costa Rican property is about more than just aesthetics — it is a long-term investment in comfort, energy efficiency, and durability. Aluminum has proven itself time and again as the material best suited to the country's tropical conditions, and ALPES stands out as a manufacturer that combines Chinese manufacturing scale with European-level quality and design.
