LIJAN GROUP operates through its flagship entity LIJAN INSULATION CONT. LLC, with two primary verticals:

1.    Industrial Thermal Insulation 
2.    Renewable Energy Solutions, including Green Roof Ventilators, Solar Tubular Skylights, and Lilly Bright Daylighting Systems.

LIJAN provides repair and maintenance services to industries like power, desalination, and oilfields, offering both onshore and offshore solutions with sustainability in focus.

LIJAN GROUP contributes to carbon footprint reduction through thermal insulation, energy-efficient jacketing, and renewable ventilation and daylighting solutions. Using solar tubular skylights and wind-driven green roof ventilators, we promote zero-energy cooling and lighting systems that drastically reduce electricity consumption and CO2 emissions.

“Decarbonising Together” reflects LIJAN GROUP’s mission to lead and support collective sustainability efforts. Through innovative insulation, ventilation, and daylighting systems, we help businesses and communities lower energy use, reduce dependency on fossil fuels, and build a greener future together.

LIJAN GROUP has extended its operations to India and the MENA region, offering services to power plants, petrochemical industries, commercial buildings, and offshore platforms. Our team continues to expand into global markets, delivering sustainable insulation and ventilation solutions.

The Windolite Green Roof System by LIJAN GROUP provides natural ventilation and daylighting using wind-driven ventilators and UV-resistant polycarbonate skylights. These systems reduce reliance on electricity, improve indoor air quality, and enhance building energy efficiency through zero-carbon operation.

The Lilly Bright Skylight provides high-impact natural lighting using UV-protected, weather-resistant materials. Unlike conventional skylights, it prevents overheating, blocks UV rays, and delivers consistent light transmission without yellowing—making it a long-life, maintenance-free daylighting solution.

Ventilator sizing is based on building height, indoor activity, and required ACH (Air Changes Per Hour). LIJAN GROUP uses precise calculations to ensure that the number and size of wind-driven ventilators match the ventilation needs of each facility, usually ranging from 5 to 30 ACH.

8(a) What is Air Changes Per Hour (ACPH or ACH) in LIJAN GROUP’s Green Roof Ventilators?

ACH (Air Changes per Hour) indicates how many times the air inside a room is completely replaced in one hour. For instance, 6 ACH means the full volume of air is changed six times per hour, ensuring improved indoor air quality and temperature control through natural ventilation.

The typical ROI (Return on Investment) for LIJAN’s Green Roof Ventilators is 2–3 years compared to electric exhaust systems. Key benefits include:

•    Zero operational & maintenance cost
•    Silent operation
•    Carbon neutrality
•    Longer lifespan
•    No civil defence approval required

LIJAN GROUP’s polycarbonate skylights offer:

•    Superior impact and UV resistance
•    No fiber bloom or yellowing
•    High light transmission
•    Better thermal performance
•    Durability and low maintenance

These features make them more reliable than GRP skylights for industrial daylighting.

No. LIJAN GROUP’s ventilators are engineered with a bevelled, overlapping 42-blade design and continuous 24/7 rotation, ensuring leak-proof performance even during heavy rain.

Yes. These natural roof ventilators utilize the stack effect—hot air rises and exits through the ventilator, drawing in cooler outside air. This passive method provides continuous airflow, resulting in better indoor comfort and lower energy usage.

LIJAN’s ventilators are made from AA1100-grade aluminum, known for being lightweight, rust-resistant, and enabling high RPM. This leads to better airflow discharge and long-term durability compared to other metal fans.

We use customized soaker panels and a vertically rotating fan shaft that delivers frictionless, high-speed operation. This ensures leak-proof installation, maximum airflow, and long product life.

Our trading division offers Marine-class A60-rated insulation materials like:

•    Rockwool
•    Ceramic fiber
•    Calcium silicate
•    Stainless steel accessories (hooks, washers, pins)
•    High-temperature glass cloth

These materials are ideal for marine vessels and onshore/offshore insulation needs.
