When it comes to modern window solutions that combine space-saving design with casement-level sealing performance, side press windows have emerged as a game-changing innovation. Among these, the TS130 Side Press Window from ALPES stands out as a premium option engineered for homeowners and builders who refuse to compromise between functionality and aesthetics. Understanding the available sizes and dimensions is essential when planning your project — whether you're considering sliding window replacement or specifying windows for a new build.
A side press window (also called a side-pressure window) is an advanced window type that merges the horizontal sliding mechanism of traditional sliding windows with a side-pressure sealing system. When closed, the sash compresses tightly against the frame — delivering the same airtight and watertight performance you'd expect from a high-quality casement window, but without any inward or outward swing.
This innovative design means no collision with curtains, faucets, backsplashes, or furniture. It also means you get the best of both worlds: the space-saving convenience of a slider and the thermal performance of a casement. For those weighing the casement window vs sliding window debate, the side press design offers a compelling middle ground.
The TS130 from ALPES is a side press window built with industrial-grade precision. Before diving into size options, here are the core technical parameters that define this model:
| Parameter | Specification |
|---|---|
| Profile Thickness | 1.8 – 2.0 mm (meets new national standard) |
| Profile Grade | 6060-T66 Aluminum Alloy |
| Frame Wall Width | 130 mm |
| Glass Sash Thickness | 55 mm |
| Sash Width | 75 mm |
| Frame Width | 26 mm |
| Track Height | 53 / 31 mm (high/low track) |
| Opening Method | One Fixed + One Movable / Middle Fixed + Two Sides Movable |
| Hardware | German ROTO side-pressure hardware system |
| Load-Bearing Pulleys | 200 kg capacity |
| Locking System | Eight-point locking system |
As a custom aluminum window manufactured by a professional aluminum sliding window supplier, the TS130 is built to order — meaning dimensions are tailored to your specific project requirements. The 130mm frame depth provides exceptional structural rigidity, allowing for larger panel sizes than many competing side press models on the market.
| Configuration | Width Range | Height Range | Best For |
|---|---|---|---|
| Compact (1 Fixed + 1 Movable) | 800 – 1,500 mm | 600 – 1,500 mm | Bathrooms, kitchens, small bedrooms |
| Standard (1 Fixed + 1 Movable) | 1,500 – 2,400 mm | 1,200 – 1,800 mm | Bedrooms, living rooms, studies |
| Large (Middle Fixed + 2 Sides Movable) | 2,400 – 3,600 mm | 1,500 – 2,400 mm | Living rooms, dining areas, villas |
Note: The 200kg load-bearing pulley system allows for generously sized glass panels. The exact maximum dimensions depend on the glass type, wind load requirements of your region, and local building codes. Always consult with the manufacturer's engineering team for project-specific sizing recommendations.
The optimal TS130 size varies depending on the room and its function. Here's a practical guide to help you choose the right dimensions for each space:
Kitchens are one of the most popular applications for side press windows. The horizontal sliding action means no outward swing to interfere with faucets, countertops, or hanging racks. Recommended sizes range from 900mm to 1,500mm in width and 800mm to 1,200mm in height — positioned above the countertop for easy reach and effective ventilation of cooking fumes. The side-pressure seal ensures kitchen odors and steam don't seep through gaps.
For bathrooms, privacy and moisture resistance are key. Smaller TS130 configurations (800mm to 1,200mm wide, 600mm to 1,000mm high) work well, especially when fitted with frosted or textured glass. The eight-point locking system provides security, and the side-pressure seal prevents humid air from leaking into wall cavities — an important consideration for preventing mold and mildew.
Bedroom windows need to balance natural light, ventilation, and egress safety. A TS130 in the 1,200mm to 1,800mm width range and 1,200mm to 1,500mm height range provides ample daylight and fresh air. The eight-point locking system also enhances security, and the smooth operation means you can easily adjust airflow from a gentle crack to full ventilation.
For living rooms and large open spaces, the middle-fixed with two movable sides configuration shines. Sizes from 2,400mm to 3,600mm wide create a dramatic visual effect with a large central glass panel flanked by two operable sashes. The 75mm sash width keeps sightlines slim, and the 200kg pulley capacity means the movable panels can be substantial without sacrificing smooth operation.
Unlike ordinary sliding windows that rely on simple overlap sealing, the TS130 uses a four-sided continuous sealing strip with upper rail frame sealant. This side pressure rubber strip seal achieves casement-level sealing performance — but it requires precise frame and sash alignment, which is why professional measurement and installation are critical.
The TS130 is equipped with German ROTO hardware specifically designed for side-pressure windows and doors. This premium hardware system, combined with 200kg load-bearing pulleys, enables larger sash sizes and heavier glass configurations than budget alternatives — without compromising on operation smoothness or longevity.
The TS130 supports a range of extended functions that can affect frame depth and sizing, including inward-opening sash mesh, integrated glass railing, anti-theft grille, and both inward and outward opening mesh screens. Discuss these options with your supplier early in the planning process to ensure the frame dimensions accommodate your chosen features.
Accurate measurement is essential for a proper fit and optimal performance. While we always recommend professional measurement, here's a basic guide to understanding the process:
Remember that window size and rough opening size are not the same. The rough opening must be slightly larger than the window frame to allow for leveling, shimming, and proper sealing. A general rule of thumb is to allow approximately 10-20mm of clearance on each side and 10-15mm at the top and bottom.
