Comparing TOSTEM Series: Which Aluminium System Suits Your Home?

Choosing the right windows and doors for your home can feel confusing. On one side, you want strength, safety, and good insulation. On the other, you want a modern design that looks great without costing too much. Many homeowners struggle to balance these needs because most products either focus only on price or only on premium features.

This is where TOSTEM comes in. With a range of aluminium window designs for various budgets and styles, TOSTEM makes it easier to find a solution that fits your home. In this post, we’ll explore how each series performs so you can make a smart, confident choice.

The Grants Series: For Limitless Views

The standout feature of Grants is its ability to hold large glass panels. By maximising glass and minimising aluminium frames, it creates wide, open views, almost like a panoramic picture frame. This makes it ideal for villas, penthouses, and homes with tall ceilings.

Key Features of the Grants Series:

• Symmetrical Frame Design: Clean, balanced frames that give the window a neat and modern look.
• Concealed Hardware: Hardware is hidden from view, so from a distance, the window looks like a fixed glass panel.
• Overlapping Meeting Stile: The panels overlap neatly at the centre, improving closure and maintaining a smooth appearance.
• Integrated Screen System: The screen is built into the frame, keeping insects out without disturbing the overall design.

Grants is the go-to choice when you want your aluminium sliding windows and doors to frame the outdoors beautifully, while still delivering premium performance.

While the Grants series is all about size and scale, the ATIS series is about how you interact with your windows every day. Often described as “art in motion,” ATIS is designed for homeowners who value both beauty and smart functionality.

The ATIS Series: Made for Modern Entrances

ATIS stands out because it makes everyday actions like opening a window or locking a door smoother, easier, and more intuitive.

Why Choose ATIS?

• The Operator Handle:The ATIS window can be fully operated from the operator handle itself. By simply rotating the handle, the window opens or closes smoothly
• Smart Insect Screens: Hidden within the frame, the screen stays out of sight when not in use, keeping the design clean. The smart, almost invisible insect screen is 40% thinner, providing a 20% clearer view than regular screens.
• Safety Stoppers & Limit Arm: Concealed hardware means no visible hinges or latches interrupting the sleek design.

ATIS is the right choice if you want aluminium window designs that combine high aesthetic value with innovative usability, offering a sophisticated solution for modern living.

The WE Plus Series: High Performance for High-Rises

Living in a high-rise apartment or in areas with heavy monsoons means your windows must be built for strength. The WE Plus series is designed exactly for that. It has been tested to handle strong winds and heavy rainfall, making it a trusted choice for tall buildings and coastal homes.

What makes WE Plus special is that it combines resilience with style. You still get the slim, elegant profiles with Japanese design, but with the added protection needed against tough weather conditions.

Performance Highlights of WE Plus:

• Wind Load Resistance: Withstands wind pressure up to 1600 Pa, keeping windows stable even on upper floors.
• Water Tightness: Advanced nanogaskets and drainage valves prevent water from seeping in during heavy rain.
• Air Tightness: Blocks dust and noise, creating a calm and comfortable indoor environment.

For projects where wind speed and rain intensity are major concerns, WE Plus delivers peace of mind without bulky frames or compromising on design.

Quality doesn’t always have to come with a luxury price tag. The WE 70 series brings TOSTEM’s trusted engineering to everyday residential projects, striking the right balance between cost, durability, and design.

Versatile and practical, WE 70 fits seamlessly into standard homes, offering a clear upgrade over traditional wooden or locally made aluminium windows. Like TOSTEM’s premium lines, it is pre-engineered with precision, so every window arrives perfectly cut and ready to install.

Benefits of the WE 70 Series:

• Consistent Quality: Made in a controlled factory setting, avoiding the flaws common in locally assembled windows.
• Durability: Protected with TEXGUARD coating, ensuring the finish resists heat, sunlight, and water for at least 40 years.
• Variety: Available in multiple styles, sliding, casement, and awning, so you can match different room layouts.

If you’re renovating or building a standard residential project and want windows that are reliable, long-lasting, and easy to maintain, WE 70 is the smart choice.

How to Choose the Right Doors & WIndow Series

Choosing an aluminium window design isn’t just about picking the one that looks best in a showroom. The right choice depends on practical factors that affect comfort, safety, and cost. Here are three key points to guide your decision:

1. Assess Your Location

Where you live matters. If your home is on the 15th floor facing the sea, strong winds are a major concern. In this case, the WE Plus series is the safest option because of its structural strength. On the other hand, if you’re in a ground-floor villa with garden views, the Grants series lets you open up entire walls for a panoramic experience.

2. Consider Usage

Think about how often you will use the windows. For spaces like kitchens or studies where windows are opened frequently, the ATIS series offers ergonomic handles and smart features that make daily use easier. For sliding doors or fixed glass panels that stay open during gatherings, the smooth rail systems of Grants or WE Plus are ideal.

3. Balance the Budget

A smart approach is to mix and match. Use the WE series in the living room to create a striking “wow” factor, while choosing the WE 70 series for bedrooms and bathrooms where practicality matters more than expansive views. Since all TOSTEM series share the same colour finishes and TEXGUARD protection, they blend seamlessly across your property.

Conclusion

Your home protects you from the world while keeping you connected to it. Whether you prioritise the sweeping elegance of the Grants series, the innovative functionality of ATIS, the robust protection of WE Plus, or the reliable value of WE 70, sticking with a pre-engineered system ensures longevity.

Upgrading to a high-quality aluminium system is an investment in your property’s future value. By aligning the series capabilities with your specific architectural needs, you ensure that your windows and doors perform beautifully for decades to come.
