Selecting the right window

Aluminium Casement Windows Price

Why do we often hear that choosing the right window is a difficult decision!

The product is Complex – Window has many moving parts. It must have high strength and long life, with excellent sealing against water, noise & dust. Manufacturing and Installation is an even more complex process – The window size has to be measured before production & each window becomes an independent project. The complexity grows multi-fold as building height increases – Biggest challenges are wind load and protection from horizontal rain.

Here are some factors to consider when selecting the right window:

  1. Purpose: Determine the primary purpose of the window. Is it for ventilation, natural light, or simply for aesthetic purposes?
  2. Style: Consider the style of your home and choose a window that complements it. There are various styles to choose from, including double-hung, casement, bay, awning, and sliding windows.
  3. Size: Choose a size that suits the room’s scale and purpose. Larger windows can provide a more open and spacious feel, while smaller ones can offer a cozy and intimate atmosphere.
  4. Orientation: Consider the orientation of the window in relation to the sun and the view outside. South-facing windows provide ample sunlight, while east-facing windows can provide a beautiful sunrise view.
  5. Energy Efficiency: Look for windows that are energy-efficient to help reduce heating and cooling costs. Look for windows with high insulation ratings and Low-E coatings.
  6. Materials: Choose a material that suits your budget, style, and maintenance needs. Common materials include vinyl, wood, aluminum, and fiberglass.
  7. Security: Consider the safety and security of the window. Look for windows with durable locks and shatter-resistant glass.

Here is a comparison of Different Window Materials and their suitability for modern buildings.
