The surface temperature is lower than
the ambient temperature after application
The impact of global warming is receiving increasing attention, with a growing demand for insulation, thermal insulation, and energy-saving carbon reduction products. Traditional materials such as PE polyethylene and PU polyurethane foam are unsuitable for use on exposed surfaces and exterior walls, as they cannot effectively resist water and moisture infiltration, leading to ineffective insulation and thermal insulation. Our advanced environmentally friendly insulation materials effectively reduce surface temperatures post-construction, with multiple successful cases showing surface temperatures lower than ambient temperatures. These environmentally friendly insulation materials can achieve low VOC emissions that are environmentally friendly, along with excellent insulation and thermal insulation effects. They can save energy by about 30% to 40% and reduce electricity consumption by up to 50%. Our user-friendly systematic construction gives customers the best choice for energy saving, carbon reduction, and significant cost savings!
Our comprehensive maintenance service can help you to solve insulation and thermal insulation problems, including on-site measurements, inquiries about project prices, and professional advice. We aim to address various temperature and water leakage issues in existing building structures using advanced product technology, such as condensation due to temperature differences, heat absorption on village house rooftops causing overheating in lower rooms, high heat absorption rates in glass curtain walls, increased electricity costs from long-term refrigeration in cold storage units, significant power consumption increases in data centers requiring low temperatures, unbearable heat in village house rooftop glass roofs/container houses/tin houses, and excessive heat dissipation in various high-temperature equipment pipelines, among others. The scope of insulation and thermal insulation projects includes village house roofs, rooftops/surfaces, cold storage unit floors, ducts, hot water pipes, steam pipes, storage tanks, data centers, and various insulation and thermal insulation projects of all sizes. Additionally, we closely cooperate with Hong Kong’s supplier of nano-penetrating waterproofing and leak-proof materials – Tru-Seal International (HK) Limited, to provide waterproofing and leak repair services. The engineering scope includes concrete spalling, upper floor water leaks seeping to lower ceilings, exterior wall water leaks infiltrating indoors, efflorescence, rooftop leaks, living room/bedroom windowsill leaks, interior wall leaks, canopy/gap/concrete crack leaks, elevator shafts/basements/parking lot leaks, estate platform planter leaks, air conditioner windowsill leaks, bathroom bathtub leaks, and more.

Ocean Free Limited provides one-stop professional maintenance services to address insulation, temperature, and water leakage issues for individuals troubled by various building-related problems.
We are committed to promoting environmentally friendly insulation products designed for building structures, aiming to solve a variety of temperature and water leakage issues in existing buildings using advanced product technology. These issues include condensation due to temperature differences, overheating in lower rooms caused by heat absorption on village house rooftops/surfaces, high heat absorption rates in glass curtain walls, increased electricity costs from long-term refrigeration in cold storage units, significant power consumption increases in data centers requiring low temperatures, unbearable heat in village house rooftop glass roofs/container houses/tin houses, excessive heat dissipation in various high-temperature equipment pipelines, and more. Our insulation projects cover a wide range, including village house roofs, rooftops/surfaces, cold storage unit floors, ducts, hot water pipes, steam pipes, storage tanks, data centers, and various insulation, thermal insulation, and waterproofing maintenance projects of all sizes. Our environmentally friendly insulation products have been successfully used in various insulation and waterproofing maintenance projects in new and old residential buildings, commercial towers, tenement buildings, shophouses, and churches.
Our experienced construction team, in collaboration with Taiwan’s high-quality environmentally friendly insulation product technology and professional expertise, eschews traditional insulation materials such as organic materials like EPS and PU or inorganic fiber structures like fiberglass, rock wool, and perlite. We solve insulation and thermal insulation problems in a non-traditional manner, focusing on areas requiring insulation like insulated pipes, air conditioning circulation pipes, data centers, cold storage units, building exteriors, village house rooftop glass roofs/container houses/tin houses, and other locations affected by temperature. Since humidity and temperature can affect each other, if there are water leakage issues in the area being treated, they must be addressed before insulation work begins.

We collaborate closely with Hong Kong’s nanotechnology waterproofing and leak prevention material supplier – Tru-Seal International (HK) Limited. Our experienced construction team, in conjunction with European unconventional concrete nano-seepage waterproofing product technology and professional skills, break through the technical limitations of common techniques such as grouting for leak prevention, injection, three-felt four-oil, waterproofing oils, waterproofing membranes, and asphalt, using a non-traditional approach to repair and address troublesome water leakage issues. We primarily focus on common problems such as concrete spalling, efflorescence/alkali-aggregate reaction, and concrete powdering found frequently on exterior walls, interior walls, ceilings, and underground areas. We now offer professional notary water leakage detection and damage assessment services to help clients who are affected by water leakage issues file claims.
We provide various indoor and outdoor professional waterproofing, leak prevention, and concrete repair services, targeting areas including concrete spalling restoration, upstairs leaks seeping into ceilings below, exterior wall leaks seeping into interiors, efflorescence/alkali-aggregate reaction, rooftop and ground leaks, living room and bedroom window sill leaks, interior wall leaks, awning/cracks/concrete crack leaks, elevator shafts/lift pit/basements/parking lot leaks, podium planter leaks, air conditioner window sill leaks, bathroom tub leaks, and more.

Our range of advanced environmentally friendly thermal insulation materials are water-based, non-toxic, mold-resistant, acid-resistant, and alkali-resistant. They effectively reduce surface temperatures, with multiple successful cases showing post-construction surface temperatures lower than ambient temperatures. These environmentally friendly thermal insulation materials achieve low VOC emissions, are environmentally friendly, and provide excellent thermal insulation effects. They can save energy by approximately 30% to 40% and reduce electricity consumption by up to 50%. We advocate for seamless thermal insulation layers, offering excellent waterproofing effects while significantly reducing heat and cold loss. They are more decorative and stronger than traditional products.
