From Forgotten Fittings to Foundations of Comfort: An 18-Year Journey into Doors, Windows, and Well-Being

How often do we, as homeowners or even architects, truly think about the doors and windows in our spaces? For most, they are simply functional boundaries, chosen quickly and often left to the contractor’s discretion. And yet, after 18 years in the uPVC, aluminium, and glass industry, I can say with conviction: doors and windows have an unseen power to shape how you live, feel, and even grow as a family.

In this article, based on my candid podcast discussion, I share my story, lessons learned, and actionable insights that every homeowner, architect, and builder should know. I started DoorWindowBasics.in to make a complex, jargon-filled industry accessible to everyone, and I am more committed than ever to demystifying what is truly one of the most impactful parts of your home.

 

The Hidden Importance of Doors and Windows

Why do doors and windows get so little attention in Indian homes, when they have such a visible—and invisible—impact on daily life? In most projects, people will research marble, lights, bathroom fittings, but for doors/windows, they simply trust the architect’s contractor.

The problem:

• Every home is unique, and so is every owner’s need.
• The wrong choice of window or door system isn’t just an aesthetic mistake—it can affect sleep, stress levels, health, and even monthly utility bills.
• Critical requirements like noise insulation, thermal comfort, and even daylight are overlooked, leading to regrets that last years.

My Own Awakening: From Industry Insider to Consumer Advocate

I entered the glass industry in 2006—drawn by the endless variety of what seemed like a simple product. After working with both Indian and multinational giants in glass, uPVC, and aluminium, I realized that our market is low on awareness, high on assumption, and flooded with misplaced trust in “brands” over “needs.”

What changed my mindset? Real stories of families unable to sleep due to road noise, of parents whose children’s learning and health suffered from a lack of daylight, of beautiful homes ruined by water seepage because of wrong window selections. Every one of these stories made me see how much education and conversation was needed—and how little existed.

“People will show off their marble, their bath fittings, their imported chairs, but ask about why they picked a certain window profile, and there is mostly silence. This silence—this gap in knowledge—is what I set out to change.”

DoorWindowBasics.in: The Mission & The Method

The purpose of my blog is simple: provide unbiased, practical information and help people ask the right questions before they make costly mistakes.

What sets it apart?

• No brand promotions, no commercial agenda.
• Only facts, real-life case studies, and direct answers to reader questions.
• Covers technical topics (glass choices, locking systems, energy rating, noise standards) in plain language.
• Backed by research, standards, and international best practices.

Key Lessons and Actionable Insights

• Every Home and Office Has Unique Needs

• Decisions on doors/windows shouldn’t be based on what your friend installed, or what’s trending on Instagram.
• Factors to consider: proximity to noisy roads, sunlight orientation, ventilation needs, and even lifestyle (work-from-home, elderly, children).

• Technical But Practical: Beyond the Brochure

• Thermal insulation isn’t “extra”—it’s essential for both comfort and energy savings.
• Double-glazed units (DGUs), properly sealed frames, and laminated glasses can lower air conditioning costs by up to 40%.
• Multi-point locking isn’t show-off; it’s required for actual safety and peace of mind, especially in urban areas.

• Don’t Overlook Invisible Benefits

• Soundproofing is measured in decibels, not just by “feel.” Most issues come from tiny leaks, wrong installation, or using the wrong kind of window for your environment.

• Daylight isn’t just about mood—it affects productivity, sleep cycles, and even children’s development.

• Safety: Burglar-resistant glass and intelligent lock systems can let you enjoy big windows without the old-fashioned iron grills.

• The True Cost and ROI

• While “premier” brands cost more, the price difference must be weighed against years of reduced stress, greater comfort, safety, and better resale value.

• For a 2 BHK flat costing ₹75 lakh, windows/doors are typically about 2-4 lakh—but skimping on them is a false economy when you’re investing in a multi-decade home.

• Case Studies: Learning From Real Mistakes

• A client in Narayana Industrial Area, Delhi, replicated a window system from their quiet residence, only to find it failed completely in a noisy new office.
• A five-star hotel in Agra spent years battling noise complaints, until performance-focused window solutions solved the problem—at a lower cost than replacing everything with a "top" brand.
• Hospital and school projects: Proper orientation, daylight, and insulation became critical for health, learning, and running costs.

Barriers, Myths & What Needs to Change

• The biggest enemy is the “low interest” in doors/windows—until things go wrong!
• Brand marketing often overshadows performance and requirement-based choices.
• Many professionals focus on price or aesthetics but ignore functional standards.

What the Industry, and You, Can Do Next

• Ask Questions: What are my actual requirements (noise, safety, daylight, climate)? What are the scientific metrics (decibels, energy ratings)?

Door/Window functions

• Research, Don’t Delegate Blindly: Use reliable blogs, independent experts, and case studies before finalizing.

• Ask for Demonstrations: Experience the product you’re buying, whether for sliding doors, laminated glass, or locking systems.

The Future: Evolving Standards and Growing Awareness

India is shifting from “good enough” to “what’s best for me,” albeit slowly. Increased policy focus on efficiency, growing competition, and platforms like DoorWindowBasics.in are leading the way.

What will create the biggest impact, in my view, is the willingness of homeowners to ask questions and insist on answers.

Your Role: Empowered Consumer, Builder, or Architect

Every project is a chance to do better.

• Don’t settle for the default; seek knowledge and compare options.
• Share your experiences—good and bad—so others learn and the market matures.
• Consider reaching out with your questions, success stories, or problems via DoorWindowBasics.in. I answer personally and enjoy learning from each case study.

Closing Thoughts

“There’s more to a window than meets the eye. For years, I saw doors and windows as just frames. But now I see them as the foundation of peace, comfort, and health for every home and family.”

The Risks of Relying on AI like ChatGPT for Door and Window Decisions

As homeowners and architects in India seek knowledge about door/window & glass over Internet, many are turning to AI tools like chatbots for advice on doors and windows. However, this growing trend raises concerns. I’m Shivendra Singh, writer for doorwindowbasics.in, with more than 19 years of experience in designing energy-efficient windows for Indian climates. This article explores why relying solely on AI for such critical decisions can lead to misinformation—and how to make informed choices instead.

The Problem with AI Advice

AI tools, while helpful for general knowledge, depend heavily on the questions asked. A poorly framed prompt can yield oversimplified or inaccurate answers. For instance, a recent AI response claimed low-E glass “blocks the heat but not the natural daylight,” suggesting it fully controls summer heat in India. 

This overlooks key details which i asked in another question. 

As Nassim Taleb aptly said, “That ChatGPT passes exams is much more a reflection on exams than information about ChatGPT.” The same applies here—AI’s output reflects the quality of the input, not its reliability for complex decisions.

Understanding Low-E Glass: The Facts

Low-E (low-emissivity) glass features a thin, invisible metal oxide coating that reflects long-wave infrared—heat radiating from warm surfaces like walls and floors—back outside. This reduces indoor heat gain, making it valuable in India’s 35–45°C summers. However, it does not significantly block short-wave infrared (direct solar heat), which requires tinted or double-glazed windows for effective control. Studies from the Bureau of Energy Efficiency show low-E glass, when paired with low-SHGC (Solar Heat Gain Coefficient) glazing, can cut cooling costs by 20–30% and block 99% of UV rays.

Why AI Missteps Matter for Doors and Windows

Choosing the wrong window can lead to higher energy bills, discomfort, or even structural issues. AI might miss nuances like India’s humid monsoons, coastal corrosion, or the need for soundproofing—areas where ours slimline and lift-and-slide systems excel. The screenshot’s claim that low-E glass “blocks the heat” oversimplifies this, risking misguided decisions like skipping double glazing in hot regions.

How to Make the Right Decision

• Consult Experts: Work with professionals for tailored advice.

• Verify AI Outputs: Cross-check AI suggestions with industry standards or case studies, such as our case studies which i am posting since 2013.

• Consider Local Needs: Opt for solutions like low-E glass with double glazing, suited to India’s diverse climate.

Conclusion

AI can be a starting point for knowledge, but it’s no substitute for expert guidance in door and window choices. Low-E glass is a game-changer for Indian summers when used correctly, not a magic fix as some AI responses suggest.

Last but not the least quoting once again- [Mark Twain] "What gets us into trouble is not what we don't know. It's what we know for sure that just ain't so." So BE ALERT ALWAYS.

Soundproof Sliders ?

I want to discuss the topic of soundproof sliders, particularly in the context of the increasing trend of installing glass sliders in bedrooms and living rooms, and the importance of making an informed decision when selecting a branded product. While choosing a reputable brand such as fenesta, schueco, or RSVP can certainly contribute to ensuring quality, it is crucial to also consider specific requirements for soundproofing. It has been observed that many people are often swayed by brand names without fully understanding the potential flaws or limitations of the product.

Pl read my previous articles about fenesta soundproof sliders & tostem single point locking sliders. In the case of sliders, it is important to note that conventional sliders with brush seals may not provide the desired level of soundproofing. The brush seal connection between the frame and sash can have a low impact on the effectiveness of noise insulation as well as dust proofing. Considering recent weather changes and sandstorm incidents in Delhi and Mumbai, my belief in the need to address this issue has only grown stronger. 

Over my 18 years of experience in visiting numerous projects, I have witnessed installers attempting to smoothen sliders by removing the brush seal at the bottom or top, solely to satisfy the customer. Unfortunately, this ignorance on the part of customers becomes an advantage for installers who are often hired on a contract basis, as their focus tends to be on the handover rather than the long-term performance of the product. To overcome this bottleneck, we have taken the initiative to form our own team for installation as well as after-sales service. 

Visualize the infiltration of PM10 dust particles into your living space as a result of inadequate or deteriorated brush seals on your sliders. This occurs even if you have opted for premium luxury brands like Fenesta, Schueco, Tostem, and others that provide traditional sliders equipped with brush seals. To prevent this issue, it is essential to regularly inspect and maintain the brush seals on your sliders. Additionally, consider upgrading to modern Lift & Slide with advanced sealing technology to effectively block out dust particles as well as unwanted soundproofing. Properly sealed sliders can significantly improve indoor air quality and prevent health issues related to dust exposure.

We are delighted to announce our collaboration with Sobinco Belgium, a trusted OEM partner of prestigious brands such as Schueco and Reynaers. Together, we are unveiling the Slim Lift & Slide, a groundbreaking product that we confidently believe presents one of the finest solutions available in the industry. The Lift & Slide distinguishes itself by its innovative gasket design, replacing the conventional brush seal typically found in the connection between the frame and the shutter. I wish to clarify that my intention is not to merely promote our company's Lift & Slide but to emphasize the advantages of opting for this superior alternative over traditional sliders featuring brush seals. Its exceptional air tightness rivals that of a casement window. For further clarity, please refer to the explanatory video provided below.

Thank you for your time and consideration. I look forward to discussing this further with you and exploring how our slim lift & slide can meet your specific requirements for soundproofing.
