Klass Serramenti: windows and doors that decorate, excite, and reveal who you are

Danilo Usai's radical vision has given rise to a new way of conceiving window frames: as design objects, architectural details, and symbols of artisanal perfection

An ambitious goal: to create a window frame never seen before (a window frame that furnishes and tells who you are...). Thus begins the story of Klass Serramenti, with the famous phrase of CEO Danilo Usai at the first meeting of the group: “We are here to do something unique, something that will leave its mark.” It was the company's starting point, but already there was the echo of a precise, almost obsessive vision: to make the window frame a cult object, an architectural detail that speaks of style and rigor. The window frame that tells who you are. A mantra uttered in a low voice, but with the power of an oath: “We pursue quality and perfection. At any cost.”

Creating the perfect window frame

After 25 years in the world of window and door frames, Usai decided to break the mold and found something radically new with a clear idea: to design not just a product, but an experience. A laboratory of perfection, a workshop where German precision meets Italian sensibility. Thus, Klass Serramenti was born, now with offices in Sassari and Rome, and already a point of reference for those who want not just a window or door, but the perfect window or door; a window or door that combines beauty, performance, and reliability. A window or door that is not just a technical element, but an integral part of the aesthetics and comfort of contemporary living.

The alliance with the best: the Schüco choice

To realize his vision, Klass chose to partner with Schüco, the prestigious German brand and world leader in PVC and aluminum window and door systems. It was a natural choice for someone who demands absolute precision, advanced materials, and meticulous quality control. "We couldn't have started any other way: together with the best. Schüco guarantees engineering rigor, while we at Klass bring the Italian soul of design and service."

The perfect angle

At the heart of Klass's production facility are four production lines equipped with state-of-the-art machinery, enabling millimeter-precise machining, essential for creating the famous “perfect angle,” without imperfections and without visible welds (the ultimate in elegance). But it's not just a question of aesthetics: mechanical precision also guarantees exceptional performance in terms of acoustic and thermal insulation, with a direct impact on energy savings and domestic comfort. Each component is selected from among the best available on the market: robust, durable materials, designed to withstand and enhance any architectural context.

Integrated warehouse, just-in-time production

One of Klass's greatest strengths is its internal logistics: a well-stocked and constantly updated warehouse that eliminates downtime between ordering and production. In an age where waiting has become the norm, Klass speeds things up, and does so with style. But it's not just a question of speed. The real heart of excellence lies in certified installation, carried out only by in-house teams trained according to an exclusive Klass protocol. This means zero outsourcing, zero buck-passing, maximum responsibility, and guaranteed quality even during installation.

The invisible charm of performance

Every Klass window and door is guaranteed not only for its sturdiness, but also for its thermal and acoustic performance, which exceeds all standards, with a direct impact on energy savings and living comfort. In addition, Klass offers an after-sales service of scheduled maintenance that borders on tailor-made care.

Speed, reliability, responsibility: installation according to Klass

Another pillar of the Klass system is the internal and certified management of installation. Installation teams are not outsourced but trained directly in-house according to a precise and replicable protocol. This means uniformity of method, direct responsibility, and, above all, guaranteed perfect installation. In addition, thanks to a well-stocked internal warehouse, Klass is able to drastically reduce waiting times, ensuring fast and punctual production and delivery. “Those who come to us have no time to waste. They want a job done well, and done quickly.”

The window frame loved by architects and interior designers

The Klass window frame in wood-effect PVC is a true technological masterpiece. The wood-effect PVC model by Schüco, with realistic grain and oak texture, is a sophisticated and functional alternative to natural wood: warm to the eye and durable over time. “We have created a window frame that furnishes your home and tells your story.”

Design that furnishes: More light, more space, more beauty But perhaps it is the design that is the true trademark of Klass.

The Klass window frame stands out for its ultra-thin profiles, designed to leave maximum space for light and the landscape. In architecture that is increasingly oriented towards continuity between interior and exterior, this feature makes all the difference. The minimal profiles, reduced to the essentials, free up light and amplify the perception of space. The result is unparalleled brightness, which transforms the atmosphere of the rooms and enhances every design detail. The window frame thus becomes an architectural form, a gesture of elegance that defines the language of living. “Our customer is like us: they love what is essential, sober, functional, and perfect. They do not accept compromises. They want a product that represents them...that speaks their language.”

Minimalism, style, and elegance

But what truly makes Klass windows and doors unique is their formal elegance. Their clean, minimalist, refined lines make each window and door a design object that blends naturally into contemporary, classic, or prestigious settings.

For all these reasons, Klass Serramenti is not just a company. It is a philosophy. It is the result of a vision, a rigorous aesthetic, and a commitment to craftsmanship. A window onto a better world.
