A Satisfied Homeowner in BC, Canada

After experiencing another rainy winter and a brief yet sunny summer in Vancouver, I can now confidently share our family's experience with this complete DERCHI door and window system. From the entry door to the casement windows, sliding doors, and the stunning folding doors throughout our home, they are more than just building components—they are key to enhancing our quality of life and sense of home.

1. The Entry Door: The First Impression of Security and Aesthetics
When we chose the DERCHI entry door, we were drawn to its solid aluminum frame structure and clean, modern design lines. After installation, its substantial feel and perfectly tight seal exceeded our expectations. In Canada, winter warmth and security are paramount. This door provides excellent thermal insulation, significantly reducing heat loss in the foyer, and its multi-point locking system offers complete peace of mind. Neighbors often compliment its "stylish look."

2. Casement Windows: Framing the View, Keeping the Elements Out
We installed DERCHI casement windows on the main scenic sides of our house. Their exceptional sealing and structural stability perform remarkably well against heavy rain, wind, and snow. The sashes operate smoothly and close quietly and tightly, with virtually no drafts. To our delight, the high-transparency glass combined with the slim frame design maximizes the view of the backyard mountains and natural light indoors. Sitting by the window with coffee, watching the snowy landscape, has become our most cherished winter pastime.

3. Sliding Doors: Seamlessly Connecting Indoors and Patio
The sliding door from our living room to the wooden deck is central to our interaction with the outdoors. The track on DERCHI's sliding door is incredibly smooth; even the large panels glide effortlessly. The sealing strips are well-designed, effectively keeping out dust, moisture, and insects. When fully opened, the indoors and outdoors almost merge into one, perfect for summer barbecues and gatherings, greatly enhancing the sense of space and ventilation.

4. Foldng Doors: The Space Magician, A New Way to Embrace Nature
This is our family's favorite feature! Transforming an entire wall in the dining room into DERCHI folding doors has redefined the space. When folded, the panels stack completely to one side, instantly turning the dining area into an open "sunroom" or semi-outdoor veranda. Whether hosting parties or simply enjoying the summer breeze and autumn colors, it offers unparalleled flexibility and openness. The craftsmanship is superb, with all panels moving in smooth unison, creating a highly modern visual effect.

Overall Impressions:

Quality & Detail: From the feel of the profiles and the smoothness of the hardware to the professionalism of the installation team (who coordinated seamlessly with our local contractor), DERCHI's commitment to quality is evident.

Climate Adaptability: In Canada's variable climate, this system has proven itself, delivering satisfactory performance in insulation, soundproofing, and wind resistance.

Design Integration: The modern, minimalist design language blends perfectly with our contemporary-style home, elevating the overall look of the property.

Worth the Investment: As a significant home investment, I believe it offers full value for money, providing long-term returns in energy efficiency, user experience, and aesthetics.

If you are also in Canada looking for an aluminum door and window system that balances performance, beauty, and durability, DERCHI is definitely an option worth serious consideration. It's not just a door or a window—it's a pathway to a more comfortable, more connected lifestyle with nature.
