Our paint has been specially designed for vinyl windows and engineered for maximum durability and heat reflection:

  • Non-toxic, non-hazardous, non-flammable, environmentally friendly, lead- and chromium-free;
  • Has excellent cohesion to the vinyl. It is elastic and moves with the vinyl as it expands and contracts. Also, the paint has exceptional abrasion and impact resistance.
  • Ensures both long-term color retention and low heat absorption.

Annealed glass

Annealed glass, commonly known as the standard glass, undergoes a thermal treatment process followed by slow cooling to eliminate internal stresses. It is commonly utilized in applications where safety considerations are not a primary concern.

Fully tempered glass

Fully tempered glass is significantly stronger than annealed glass, with a strength four times greater. In the event of breakage, it shatters into small, safe pieces, minimizing the risk of injury.

Heat Treated Glass

Heat-strengthened glass undergoes a slower cooling process compared to tempered glass, resulting in a lower compression strength. However, it still provides approximately twice the strength of annealed glass.

Laminated Glass

Laminated glass can withstand strong impacts. It is a superior solution to safety glazing.

Laminated glass does more: it is the type of safety glazing that also remains intact within the window frame.


Neat Glass

Unlike regular exterior window surfaces, Neat glass requires minimal maintenance. With Neat technology, the glass stays cleaner for longer periods. And when the time comes to clean, you'll find it quick and effortless.

Understanding Sliding Windows

Sliding windows are designed to move horizontally along a track, offering a unique opening mechanism. They are celebrated for their contemporary appearance, ease of operation, and their ability to provide unobstructed views of the outdoors.

Horizontal Sliding Windows

Horizontal sliding windows, also known as slider windows, are equipped with sashes that slide horizontally along a track. Here's why they are an excellent choice:

  1. Effortless Operation: Operating horizontal sliders is straightforward. A gentle push or pull allows for excellent ventilation and invites abundant natural light indoors.
  2. Space Efficiency: Unlike windows that swing outward, horizontal sliding windows don't require clearance, making them ideal for spaces with limited room to maneuver.
  3. Modern Aesthetic: The clean lines and contemporary design of horizontal sliding windows make them versatile, suitable for various architectural styles.

Vertical Sliding Windows

Vertical sliding windows, commonly referred to as single-hung or double-hung windows, open vertically. They come with distinct features:

  1. Independent Sashes: Vertical sliding windows have two sashes, one positioned above the other. In single-hung windows, only the bottom sash is movable, while double-hung windows enable both sashes to operate independently.
  2. Precise Ventilation Control: Vertical sliders provide precise control over ventilation. Adjusting the upper and lower sashes allows you to regulate airflow, which is advantageous in rooms where temperature and ventilation needs vary.
  3. Timeless Elegance: Vertical sliders offer a classic, timeless appearance that can enhance the aesthetic appeal of both traditional and modern homes.
