Cuts out near-infrared rays, the main cause of heat, while leaving visible light intact

Reduces air conditioning load and helps create a comfortable indoor environment
The heat from the windows has a big impact on indoor temperatures.
In office buildings and restaurants in the summer, air conditioning accounts for a large proportion of electricity consumption.
A survey by the Ministry of Economy, Trade and Industry's Agency for Natural Resources and Energy shows that approximately 49% of electricity consumed in office buildings and approximately 51% of electricity consumed in restaurants is due to air conditioning.
The cause of this is heat (near infrared rays) entering through windows.
Sunlight is divided into ultraviolet rays, visible light, and infrared rays. Although infrared rays (especially near-infrared rays) are invisible to the naked eye, they have a significant impact on the indoor environment as heat.
Near-infrared rays contained in sunlight pass through glass and enter the room, causing the room temperature to rise, which increases the operation of air conditioning and ultimately leads to higher electricity costs.
In order to achieve both energy conservation measures and comfort in a facility, the most important point is how to reduce the amount of heat entering and leaving through the windows.
Heat-shielding coating that utilizes existing windows to improve energy efficiency
What is Macnicut a heat-insulating paint for windows?
Macnicut, a heat-shielding coating for windows, is applied to existing window glass to efficiently block near-infrared rays (heat rays), the main cause of heat, and reduce indoor heat and air conditioning load.
It allows visible light contained in sunlight to pass through, saving energy without compromising the brightness of the room. It also blocks approximately 99% of UV rays.
Installation from the indoor side is expected to maintain performance for a long period of time, and the product meets the "F☆☆☆☆" rating standard for the lowest formaldehyde emission, ensuring durability and safety.
Energy savings and improved comfort can be achieved through windows
Benefits of using Macnicut heat-insulating window paint
-
◆ Energy saving and cost optimization by reducing air conditioning load
By effectively blocking near-infrared rays (heat rays), the rise in room temperature in the summer can be suppressed, reducing the amount of air conditioning required.
Improving cooling efficiency is expected to reduce power consumption and optimize energy costs, contributing to decarbonization measures and ESG management initiatives. -
◆ Maintaining a comfortable indoor environment with good brightness
The design allows visible light to pass through, so the room does not become dark and natural brightness and visibility are maintained.
It can be installed as a heat-blocking measure without compromising comfort in spaces where brightness is important, such as office spaces, stores, and waiting areas. -
◆ Maintaining asset value and beauty by blocking UV rays
By blocking approximately 99% of ultraviolet (UV) rays, it prevents fading and deterioration of products, interiors, fixtures, etc. caused by sunlight.
It also helps maintain the beauty of commercial facilities and offices and preserve asset value. -
◆ Reduced cleaning and hygiene management burden (UV protection + antibacterial measures)
By cutting ultraviolet rays, it is less likely that light from indoor lighting will leak outdoors, which is expected to reduce the phenomenon of insects being attracted to window glass at night.
Many insects are said to be phototactic, reacting to ultraviolet light with a wavelength of 300 to 400 nm. Reducing the number of insects that attach to areas around windows reduces the burden of cleaning work and makes hygiene management easier.
In addition, the antibacterial properties of the dedicated cleaner suppress the growth of bacteria on the glass surface, making it easier to keep it clean even with daily cleaning. -
◆ Long-term durability and ease of installation and operation
Since the coating is applied from the indoor side, performance can be expected to be maintained for a long period of time (10 years or more).
It does not require glass replacement, so installation can be done in a timely and cost-effective manner. Installation can be easily tailored to suit the facility's usage, making it suitable for gradual installation or partial installation.
Visible light remains intact, while near-infrared rays that cause heat are significantly cut
How Macnicut a heat-insulating paint for windows, works
The coating film of Macnicut, a heat-shielding paint for windows, is designed to transmit visible light contained in sunlight while blocking near-infrared rays, which are the main cause of heat, and ultraviolet rays, which are of concern for their impact on the indoor environment.This effectively prevents heat from entering the room while maintaining visibility and brightness.
By applying Macnicut for windows to window glass, it is possible to create a comfortable and energy-efficient space that combines transparency, heat insulation, and UV protection.

Addressing heat and energy-saving issues in various facilities
Use scene
-
Office and tenant buildings
It is suitable for spaces that are susceptible to sunlight coming through windows, such as offices, conference rooms, and common areas.
This helps to create a comfortable working environment that maintains brightness while reducing the load on air conditioning. -
Commercial facilities (retail and restaurants)
It is effective in spaces where measures to prevent room temperature rise due to sunlight and fading of products and interiors are required.
It can be used as a heat-blocking measure to reduce the heat when customers visit the store without damaging the store's atmosphere. -
Hotels and accommodations
It is also suitable for facilities where comfort and the impression of space are important, such as guest rooms, lobbies, and common corridors.
This can be used to combat the heat in the summer and reduce the load on air conditioning while maintaining a bright indoor environment that lets in natural light. -
Medical institutions, educational facilities, and public facilities
Since it is used by many people, it is also suitable for facilities where comfort and hygiene are important considerations.
This is ideal for situations where you want to maintain a bright and open space while taking measures against the summer heat. -
〇 Factories and warehouses
It can be used as a measure to improve the working environment and reduce the load on air conditioning at work sites that are susceptible to the heat from large openings and windows.
Since it can be installed using existing windows, Its main feature is that it is easy to implement, reducing construction time and costs.
Construction flow
The construction process involves cleaning and protecting the glass surface, applying a heat-shielding coating, and then checking the drying and finishing process.
Because it does not require glass replacement, construction time and costs can be kept to a minimum, and it is also easy to implement in stages or by applying partial construction, making it suitable for cases where you want to start with measures for windows that are most susceptible to the effects of sunlight.
Frequently Asked Questions
