Frequently Asked Questions

What is the cost of aluminium slit windows?

When shopping for a window, the cost can vary based on several factors such as:

  • Manufacturing company’s reputation: The more recognized the window manufacturing company, the higher its costwill be. Despite our spot-on reputation in the housing industry, TOSTEM aluminium slit windows are priced reasonably so every homeowner can afford them.
  • Quality standards maintained: Based on the quality standards maintained in the manufacturing process, the cost of high quality aluminium slit windows can vary. Despite TOSTEM’s compliance with competitive ASTM, BIS, and JIS quality assurance standards, our products continue to remain within the arm’s reach of all our prospective buyers.
  • Aluminium Slit Window Specifications: Based on your unique customization requests, the aluminium slit windows prices can vary.

How do I choose a modern slit window design?

Consider the following factors when choosing a modern slit window:

  • Reliable window manufacturers: Purchase from a window manufacturer that complies with competitive quality standards.
  • Look for versatility and design options: Is your ideal aluminium slit window available in different colours, design orientations and glazing options.
  • Choose a product that is both cost-effective and quality-tested: While it is ideal that you look for slit windows that fall in your target price range, do not compromise on quality because a slit window is offered at a cheaper price with less-reliable manufacturers.
  • Product Durability: When choosing slit windows, it is critical to buy a durable product. Since the glass panels are fixed to the frame and cannot be closed or opened, you need to invest in a window that won’t easily break. So make sure you look for this feature while shopping for aluminium slit windows.
