When the first breeze of September sweeps through the islands, the Philippines quietly enters its Christmas season. From Manila to Cebu, malls, hotels, and office towers don their luminous attire. During these four festive months, building façades cease to be static shells. Instead, they transform into canvases of celebration, using their scale, transparency, and interplay of light to brighten the city nights and also the hearts of people.
As dusk falls in Cebu or Manila, the first sparks of light often radiate from commercial complexes and landmark towers. By day these façades symbolize contemporary architecture; by night they become glowing stages carrying the spirit of the holidays.
This transformation comes to life in SunFrame’s Philippine projects, where malls, hotels, resorts, offices, and even healthcare facilities show unique expressions of the season.
At City Mall Cebu, a 560 m² façade system of 120-series frame curtain walls and aluminum windows bathes the interiors in daylight, while at night its smooth surface becomes the backdrop for Christmas lighting.
◐ Though far smaller in scale than the Sheraton’s façade package, its clean geometry allows nearly full coverage of festive lighting, drawing foot traffic and fueling evening retail activity.
☞ Engineered for tropical wind loads and thermal performance, the façade’s high surface flatness ensures efficient installation and clear projection of decorative lighting.
Sheraton Hotel Cebu incorporates 3,780 m² of aluminum doors and windows along with 1,160 m² of balcony railings. During the holidays, the dialogue between tropical scenery and architectural lighting creates a vibrant yet refined atmosphere.
◐ Unlike City Mall, the hotel’s façade is not about sheer brightness but ambiance. From the poolside, guests can see soft lights echoing the lines of the balcony railings, balancing spatial depth with festive warmth.
☞ The Sheraton Hotel system utilizes thermal-break aluminum profiles with weather-resistant coatings. It can maintain stability in humid coastal climates while offering a durable surface for seasonal illumination.
At Camiguin Resort, 12,000 m² of curtain walling and stainless-steel glass balustrades maximize views of the shoreline. When Christmas arrives, the resort turns into an immersive scene. Lights shimmer in rhythm with the sound of the surf. A place where romance meets nature.
◐ At twenty times as large as City Mall’s 560 m² façade, Camiguin stands as a far more expansive stage for light and space.
☞ By combining thermal-break and hurricane-resistant design with 316-grade stainless railings, SunFrame makes this system robust against coastal challenges while transforming it into a reliable canvas for festive lighting.
The RealSteel Office in Quezon City features 890 m² of curtain walling and 426 m² of aluminum decorative strips. By day, it projects a modern corporate image. At night, seasonal lighting adds warmth to an otherwise austere district.
◐ In contrast to the romantic glow of resorts, the office façade carries a symbolic touch. It is enough to comfort late-working employees or passersby with a sense of seasonal cheer.
☞ Powder-coated finishes are applied on both curtain walls and decorative strips, which enables the surfaces to remain durable and flat. As a result, lighting spreads evenly without diminishing the building’s professional aesthetic.
Apple One Equicom Tower, a 17-story mixed-use development in Cebu’s business district, showcases 2,400 m² of façade. During Christmas, its illuminated frontage can be seen from kilometers away, securing its place in the city’s skyline.
◐ At nearly three times the size of RealSteel’s 890 m² façade, this landmark’s scale alone ensures its dominance in the nocturnal cityscape.
☞ Combining invisible curtain wall systems with ACP cladding, the tower achieves a flush-glass surface for uniform light distribution, while the cladding’s durability sustains long-term performance of its lighting scheme.
At Marikina Valley Medical Center, a 400 m² unitized curtain wall focuses on daylighting and energy efficiency. During Christmas, there is no extravagant display, but soft illumination filters through the façade, extending the concept of “healing space” to the city outside.
◐ Rather than sprawling commercial façades, its modest scale delivers a quieter yet meaningful presence, offering citizens a sense of calm and reassurance.
☞ Optimized for daylight penetration, airtightness, and watertightness, the system enables interior lighting to blend seamlessly with external seasonal glow.
☁ Durability and Safety: Proven performance against typhoons, high humidity, and coastal exposure.
❀ Form and Function Together: By day, façades capture natural light; by night, they come alive with expressive illumination—seamlessly merging utility and beauty.
✲ Energy and Sustainability: Advanced curtain wall solutions such as double glazing, thermal breaks, and powder coating contributes to efficient, long-term operations.
✔ Energy-Smart Systems: LED technology and intelligent controls are rapidly becoming the industry standard.
✔ Integrated Design: Invisible curtain walls, decorative profiles, and lighting systems are conceived and executed as a unified whole.
✔ Contextual Solutions: Lighting strategies are increasingly tailored to the distinct needs of malls, hotels, offices, and healthcare facilities.
In the Philippines, Christmas is not a single night of lights nor a fleeting carol. In fact, it is a four-month celebration woven into the fabric of city life. Through its façade systems, SunFrame enables buildings to speak in two languages: realism by day, poetry by night. A façade is no longer the boundary of structure, it is also the beginning of celebration.
