In a city as busy and dense as Singapore, noise is a daily reality—whether it’s the rumble of MRT trains, the buzz of traffic, or the clatter of nearby construction. Over time, constant noise can disturb your sleep, affect your mood, and lower your quality of life.

Ho Ho’s soundproof windows, also known as double glazed windows, offer an effective solution. Designed to reduce noise dramatically, our systems are suitable for HDB flats, condominiums, landed homes, and commercial spaces. We help you create a quieter, more comfortable living environment—so you can rest, focus, and relax without disturbance.

What Is Double Glazed Window?

Double glazing involves using two panes of glass separated by an air gap to reduce the transmission of sound and heat. This layered structure acts as a powerful barrier that disrupts and absorbs sound waves before they enter your space—effectively lowering indoor noise levels and improving comfort.

Double Glazed Window Options in Singapore

In Singapore, double glazed windows typically come in two thickness options: 16 mm and 18 mm. At Ho Ho, we believe in delivering the highest quality, which is why we use the 18 mm premium configuration as our standard offering for superior acoustic performance.

Standard Double Glazed Glass Window (16 mm):

  • Two layers of 5 mm standard glass

  • A 6 mm insulating air gap

  • Total thickness: 16 mm (compared to 5 mm in typical single-glass windows)

Premium Double Glazed Glass Window (18 mm):

  • Two layers of 6 mm glass

  • A 6 mm air gap

  • Total thickness: 18 mm

  • Offers enhanced sound insulation and improved structural strength

Our Sound Proof Window is Engineered for Maximum Acoustic Performance

Our sound proof windows go beyond just thicker glass. Every element is designed to work together for superior soundproofing:

  • Euro profile aluminium frames – stronger and thicker than conventional frames

  • Multi-point locking system – creates a uniform and airtight seal when closed

  • Rubber edge seals – prevent air and sound leakage

  • Middle bar between panels – eliminates gaps in sliding or swing configurations to maintain airtightness

Together, these features reduce external noise, bringing outdoor noise levels like traffic (80–90 dB) down to a comfortable indoor range of 40 to 50 dB—ideal for rest, focus, and everyday living.

Why Soundproof Windows Are a Worthwhile Investment?

man stressed by noise pollution, showing impact on brain, heart, and health from environmental noise in an urban setting so sound proof window is a great investment as it will improve standard of living and health of the homeowner

Extensive research confirms that environmental noise isn’t just annoying—it has serious health impacts.

According to the World Health Organization (WHO), noise pollution is the second largest environmental health threat, contributing to poor sleep, cardiovascular disease, and cognitive decline.

What the Research Shows:

  • European Heart Journal (2018) – Prolonged exposure to noise (e.g. traffic, aircraft) increases risk of high blood pressure, heart attacks, and strokes, due to stress hormone activation and sleep disruption.

  • RANCH Study (2005) – Children living in noisy areas have slower reading development and weaker memory performance.

  • The Lancet (2014) – Chronic noise exposure is linked to higher rates of anxiety and depression, especially when recovery periods are limited.

  • Journal of Environmental Psychology (2005) – Environmental noise in homes and offices leads to mental fatigue, reduced focus, and lower productivity.

Noise-related sleep disruption leads to fatigue, irritability, and lack of focus. Over time, it can reduce your overall well-being. With Ho Ho’s soundproof windows, you and your family can:

  • Sleep peacefully even with outdoor activity nearby

  • Concentrate better while working or studying

  • Enjoy quiet relaxation during weekends or evenings

  • Improve long-term mental and physical health

You’re not just investing in a window—you’re investing in peace of mind, better sleep, and a healthier home.

  • Significant Noise Reduction: Blocks high- and mid-frequency noise such as MRT trains, heavy traffic, neighbour chatter, and renovation work.

  • Improved Insulation: The air gap between the glass panels also reduces heat transfer—keeping your space cooler and reducing energy costs from air conditioning.

  • Enhanced Safety: The double glass construction is stronger and more impact-resistant than single-pane windows, adding another layer of protection.

  • No Fogging: Double glazing helps prevent condensation and foggy glass, which are common issues in Singapore’s humid climate.

Frequently Asked Questions

  • What can I do to enhance the security of my wooden main door?
    To enhance the security of your wooden main door, consider the following upgrades: Install a High-Quality Lockset – Use a heavy-duty deadbolt lock or a digital lock with advanced security features. Ensure it meets industry standards for strength and durability Use a Solid Core Door – Choose a solid timber core door, which is more resistant to forced entry than hollow-core or low-density doors. Add a Peephole or Digital Door Viewer – This allows you to see who’s outside before opening the door. Install a Security Bar or Door Chain – These add another layer of protection and prevent the door from being opened fully by force. Consider a Smart Doorbell or Surveillance Camera – Pair your door with a smart camera system so you can monitor and record any suspicious activity. Ensure Proper Fit and Alignment – A misaligned door can compromise security. Make sure your door closes snugly and has no gaps that could be pried open. With these enhancements, you can significantly improve the overall security and peace of mind your wooden main door provides.
  • What types of laminate door colours should I get for my doors?
    1. Woodgrain Tones (Oak, Walnut, Teak) – Ideal for creating a warm and natural ambiance – Pairs beautifully with Scandinavian, Muji, and rustic interior styles 2. Solid Neutral Colours (White, Black, Grey, Beige) – Perfect for a modern and minimalist look – White and beige brighten up the space and create a clean, airy feel – Black and grey add depth, contrast, and sophistication
  • Is it advisable to use a laminate door for the main entrance?
    Laminated doors are a popular choice due to their perfect scratch resistance, modern appearance, and low maintenance—they do not require painting or varnishing. However, they are not suitable for main entrances exposed to direct sunlight or rain. Prolonged exposure to UV rays or moisture can cause the laminate surface to discolour permanently, and unlike varnished doors, the colour cannot be restored. In contrast, varnish doors may also discolour over time, but they can be revarnished to look as good as new. If your main door is sheltered from the elements, a laminate door with a solid timber core can still be a practical and stylish option. For exposed areas, a varnish or solid wood door is a more durable and restorable choice.
  • How much does it cost to replace an HDB main door in Singapore?
    The cost of replacing a wooden HDB main door in Singapore depends on factors like the type of finish, door size, and any additional accessories. At Ho Ho, we offer direct factory pricing with no hidden charges, making quality more accessible for homeowners. Our solid laminated main doors start from $599, and the price includes: – Removal of your existing door – Professional installation – Quality lockset – Stainless steel magnetic door stopper – 1-year warranty for peace of mind

Our eco core laminated bedroom doors start from just $250 each, and the price includes: – Dismantling of the old door – Professional installation – A quality knob lockset – Stainless steel magnetic door stopper – 1-year warranty for added assurance
  • What is the lead time and process for getting a wooden door?
    After the onsite measurement, non fire-rated doors are typically installed within 2 weeks. For fire-rated doors, the lead time may extend up to 3 weeks due to the requirement to apply for an HDB permit. Installation takes about 1 hour per door. For laminated doors, the entire process is completed within the same day. However, for varnish or painted doors, the finishing work will be done on the following day to allow sufficient drying time.
  • How do I maintain, repair, and clean my wooden door to ensure its longevity?
    To keep your wooden door looking great and functioning well over the years, follow these care tips: Cleaning Regular Dusting: Use a soft, dry cloth to remove surface dust. Gentle Wiping: For deeper cleaning, use a slightly damp cloth or mild soap solution. Avoid soaking the door or using abrasive cleaners. Avoid Harsh Chemicals: Steer clear of strong chemicals or bleach, as they can damage the finish and surface of the door. Maintenance Lubricate Hinges: Apply a small amount of lubricant (like WD-40) to the hinges if the door starts to squeak. Check for Moisture Damage: Especially for doors in humid or wet areas, inspect the bottom edges and corners regularly for swelling or warping. Inspect the Lockset: Tighten any loose screws and ensure the handle and lock mechanism are functioning smoothly. Minor Repairs Scratches & Scuffs: Light scratches can often be buffed out with wood polish or a furniture touch-up marker that matches your door colour. Surface Touch-Ups: For varnish doors, revarnishing can restore the original shine. For laminate doors, scratches may not be repairable and may require panel replacement if severe.
