Installing a Soundproof Door brings many benefits—most importantly, it helps block sound from coming in or going out of a room.
Many people use soundproof panels to improve room acoustics, but they often overlook the door. As a result, the overall soundproofing may not work as expected. Even small gaps, holes, or poor sealing can let a lot of sound pass through.
A proper Soundproof Door helps seal these weak spots, keeping the sound inside and outside noise out.
With over 40 years of experience, Blue Whale Soundproof Door is a trusted manufacturer known for creating high-quality soundproof doors. Our doors not only block out noise but are also designed with fire- and smoke-resistant features, ensuring a peaceful and safe space for you.
H4 Luxury Double Door series is BlueWhale’s premium door collection, crafted for those who pursue refined taste and a life of elevated quality. It is specially designed for private villas, high-end residences, and artistic spaces.
From the selection of materials to the finesse of craftsmanship, from the surface texture to the spatial presence, every detail expresses a deep commitment to “steadiness, elegance, and individuality”.
This is more than a door — it is a work of art, and the opening statement to an ideal way of living.
Named after the historic hill city of Siena in central Italy, the H4 Siena Luxury Door is BlueWhale Door’s tribute to timeless architecture and cultural heritage.
Nestled among rolling green hills, Siena’s medieval townscape—with its red-brick buildings and winding stone streets—creates a view like no other. Every year, the famous Palio horse race festival breathes new energy into this ancient land, celebrating passion and the spirit of tradition handed down through generations.
We translated this cultural memory into our door’s sculptural language: swirling lines and rhythmic curves etched into red copper, as if time itself left graceful traces upon the surface. Each time the door opens or closes, it becomes a ritual—a dance with history.
The fairytale city of Siena unfolds step by step, its red-brick houses surrounded by endless greenery.
Following the cobblestone paths leads to the city’s soul—Piazza del Campo, a shell-shaped square that serves as both the community’s heart and the stage for the legendary horse race.
Every July and August, riders representing different districts compete in a burst of color and excitement, while crowds gather like waves to witness a tradition that transcends time. The surrounding architecture blends Gothic and Renaissance influences, embodying Siena’s cultural depth and historic charm.
Inspired by this iconic square, the H4 Siena Luxury Door features circular and hoof-like engravings that capture the speed and tension of the race. These sculpted rhythms turn the door into more than an entrance—it becomes the beginning of a story, a balance between energy and elegance.
The H4 Siena Luxury Door features a facade crafted from 99.9% pure red copper with engraved patterns that outline classical swirls and rhythmic horse-hoof patterns. This not only symbolizes the racing dynamic of the Palio but also echoes the intricate artistry of medieval metalwork. The pure red copper naturally oxidizes over time, transitioning from warm reddish hues to a rustic green patina. Each day presents a unique appearance, as if the door quietly records the passage of time.
The door frame is made of stainless steel finished with German handcrafted lacquer. Skilled artisans apply multiple delicate layers, brushing and polishing the surface to create a distinctive sheen and texture that beautifully interact with light and shadow. This infuses the entire piece with warmth and depth.
Every opening and closing is more than just a motion; it is a serene dialogue between material, light, and time, showcasing the unique artistic value of the H4 Siena Luxury Door.
The H4 Siena Luxury Door offers excellent performance in sound insulation, smoke control, and safety protection. With an average STC rating of 53, it ensures a calm and quiet interior space—ideal for modern residences that value both comfort and privacy. On-site testing has also shown a noise reduction of up to 40 dB.
The door is equipped with BlueWhale’s signature EPDM rubber seals, creating a seamless fit around the frame. This helps block out noise, insects, and odors in daily life, while also preventing smoke from leaking through in case of a fire—offering up to 20 additional minutes to evacuate or wait for help. It’s an extra layer of protection you can truly rely on.
The door adopts a double sealing system that provides excellent insulation—keeping your home warm in winter and energy-efficient in summer. And the threshold can also be upgraded with a barrier-free airtight drop seal, offering safer and more convenient access for elderly family members.
For those seeking an even higher level of safety, a 60A fire-rated smoke seal structure is available as an optional upgrade. If you’d like to learn more about the door’s construction or applications, we welcome you to reach out to our team.
