Derchi E5T Aluminum Slide Window Review

The E5T Aluminum Slide Window from Derchi Windows & Doors is one of the most popular sliding window options in the market. And in a region like Melbourne where buildings are developed to match the prevalent weather, there is a lot of benefit that you stand to gain from having this premium aluminum sliding window in your building.

Product Overview

The Derchi E5T Aluminum Slide Window represents the perfect balance of form and function. Designed specifically for residential and light commercial applications, this sliding window system combines a sleek, contemporary aesthetic with robust performance characteristics that make it ideal for Melbourne's variable climate conditions.

What sets the E5T apart from competing products is its innovative frame design, which maximizes the glass-to-frame ratio while maintaining exceptional structural integrity. The result is a window that floods interiors with natural light while providing outstanding thermal and acoustic insulation.

Product Details & Specifications

E5T Technical Specifications

To start with, let’s examine the primary features available with this window to see what makes it stand out:

E5T Performance Specifications

Beyond just the generic specs, we’ve also created this sliding window to provide some reliable added features - including the following:

Available Thermal Insulation

With the E5T sliding window, you get up to 2.5 W/(m²·K) thermal performance, as well as thermal break technology that reduces the transfer of heat considerably.

Resistance to Wind Pressure

The sliding window comes with a reinforced frame build  that allows it to withstand extreme wind loads. This provides up to 5kPa wind pressure resistance, making the sliding window especially perfect for coastal areas.

Waterproof Protection

Another factor that makes the sliding window ideal for coastal areas is its 280Pa waterproof rating. With this window, you get a sealed frame system that prevents the entry of water, especially during periods of heavy rainfall.

Reliable, Air-Tight Build

This window promises a 4.5 m³/(m.h) air leakage rate, as well as multi-point sealing that cuts down on drafts and any unwanted exchange of air. An added tight seal allows you to maintain indoor climate control while reducing your overall energy consumption.

Insulation from External Sound

The window provides up to 30dB in sound reduction. Its assembly is designed to properly block any external sounds, with double-glazing compatibility helping to reduce any acoustic intrusions.

For those quieter indoor spaces, the E5T sliding window is a great fit!

Where to Install the E5T

The E5T is exceptionally versatile, making it suitable for living rooms, bedrooms, kitchens, and home offices. Its smooth operation makes it particularly popular for areas where frequent ventilation is desired.

Primarily, you want to install this window in luxury villas and sunrooms. The windows can also be used in patios, where they provide a seamless connection between indoor and outdoor spaces.

In commercial settings, the E5T works beautifully in boutique retail spaces, cafes, and small office buildings where aesthetics and functionality must work in harmony.

Installation Tips

For optimal performance, we recommend working with certified installers who understand the specific requirements of aluminum window installation in Melbourne's climate. Key considerations include proper flashing and weatherproofing, adequate structural support for larger configurations, and correct sealant selection for long-term water tightness. Our technical team provides comprehensive installation guides and on-site support for complex projects.

Derchi Q15 Heavy Large Sliding Door Review

If you’re looking for a massive, reliable, and sturdy sliding door for your building, then look no further than the Derchi Q15 Heavy Large Sliding Door. This door is one of our bestselling products, seamlessly blending the aesthetic appeal of a sliding door and the physical strength of the aluminum material.

With the Q15 sliding door, it’s not just about finding something that’s beautiful - it’s also about having a door that secures and protects.

Product Overview

Engineered for large-format applications, the Q15 can accommodate panel sizes up to 6 meters wide and 3 meters tall—creating truly breathtaking architectural statements.

Despite its massive scale, the Q15 operates with surprising smoothness thanks to its precision-engineered tandem roller system. Each panel glides effortlessly along the track, allowing even children or elderly users to operate doors that weigh hundreds of kilograms.

Product Details & Specifications

Q15 Technical Specifications

In terms of technical specs, the Q15 sliding door definitely packs a massive punch:

Q15 Performance Specifications

Now, let’s see what makes this unique door so perfectly suited for building applications.

Thermal Performance (U-Factor)

The Q15 sliding door achieves an impressive 0.28 U.S/IP rating, which allows it to cut down on heat transfer. With its impressive insulation, you can cut down on both cooling and heating costs considerably.

Wind Pressure Resistance

The door is also capable of withstanding up to 4.5 kPa, meaning that it manages to stay stable even during periods of strong winds and rainstorms. With a glass build and a reinforced frame, it manages to hold its structural integrity consistently.

Water Tightness

You also get a door that maintains 450 Pa resistance. This would be enough to prevent water entry even during the heaviest of rains. And with its ability to maintain interior dryness, the door easily protects your furnishings and floors.

Air Tightness

With a 4.5 m³/(m·h) rating, the Q15 sliding door reduces any unwanted air exchange. As such, it cuts down on drafts and can even maintain proper indoor temperature control.

Sound Insulation

As you can expect, insulation from sound is also guaranteed with this door. It protects from sounds as loud  as 35 dB, creating a quieter environment by minimizing traffic noise and external sounds.

Where to Install the Q15

The Q15 truly shines in applications where unobstructed views and seamless transitions are paramount.

Luxury waterfront homes, penthouse apartments, high-end restaurants, hotel lobbies, and premium retail spaces are all ideal candidates. In Melbourne, we've installed Q15 systems in some of the city's most prestigious addresses, from Brighton beachfront homes to South Yarra penthouses.

Installation Tips

Given the scale and weight of Q15 panels, professional installation is essential. Structural engineers should verify that supporting walls and floors can accommodate the system's requirements.

We recommend installing the track system on a perfectly level concrete or steel substrate, with adequate drainage provisions in outdoor-facing configurations. Our project managers work directly with builders to ensure seamless integration from design through completion.

Our technical team analyzes each project's exposure conditions and recommends appropriate configurations, glass specifications, and finishing treatments. We don't believe in one-size-fits-all solutions.

Precision Engineering and Fitting

Our manufacturing tolerances are measured in fractions of a millimeter. When windows and doors arrive on site, they fit perfectly—reducing installation time, eliminating the need for field modifications, and ensuring long-term performance.
