Cheil Worldwide Created A Thermal Ad To Promote Uniqlo’s Thermal Wear

500,000 HEAT TECH WINDOW kept people warm and helped save energy


SEOUL, SOUTH KOREA – April 10, 2017 – Cheil Worldwide has created an advertisement for Uniqlo that not only promotes its heat-generating thermal wear, HEATTECH, but actually keeps people warm. Last winter, Cheil launched HEAT TECH WINDOW campaign to offer real warmth to consumers in severely cold weather.

HEAT TECH WINDOW uses bubble wrap, commonly used for packaging fragile items. Its layer of air-filled hemispheres blocks the heat conduction between indoor and outdoor, thus raising the room temperature. Just by attaching the HEAT TECH WINDOW to the window, the temperature of the room rises by 2~3°C (3.6~5.4°F)1). This saves an average of 20% on heating costs2).

With logo of HEATTECH printed on each, and the size to fit regular window sizes in Korea, 500,000 HEAT TECH WINDOWs were handed out to consumers for free via all 189 Uniqlo stores in Korea with each purchase of a HEATTECH product.


All the household and office windows which installed HEAT TECH WINDOW turned into new advertising media for Uniqlo branding. This means Uniqlo gained 500,000 free out-of-home ads throughout the winter season.

Cheil also shared the campaign video on various social media to show how to install HEAT TECH WINDOW, and reached 30 million impressions within a month in a country with population of about 50 million. As a result of the whole campaign, HEATTECH sales recorded a year-on-year growth of 203%.

“We looked for an idea that can help consumers who had to worry about the cold and heating costs every winter. Based on our observation, Uniqlo HEATTECH products and bubble wrap had similarities such as keeping the warmth and being convenient to use, so we created the HEAT TECH WINDOW,” said the creative team at Cheil Worldwide.

HEAT TECH WINDOW won 2 Golds and 2 Silvers at ADFEST 2017 which took place from 22nd ~ 25th March, 2017 in Pattaya, Thailand.
