Insulated buildings have better thermal comfort, where the desired indoor temperature can be achieved with less energy consumption; hence lowering the energy bills. Building occupants can experience more privacy and lesser noise intrusion with insulated buildings. As a non-combustible building material, Ecowool insulation provides an effective measure for mitigating the spread of flame and limiting the structural damage in the event of a fire.

Thermal insulation refers to the reduction of heat loss or gain between the building envelope, in order to achieve a desired indoor environment. Acoustic insulation on the other hand is a measure to dampen the sound transmission from traveling between the adjacent space , for an enhanced privacy and comfort.

Ecowool comes with a 70-year warranty for plain glass mineral wool insulation, and 10 years for glass mineral wool insulation with facings. We recommend our customers to check with our team for further information on the warranty coverage, along with its terms and conditions.

Ecowool is a sustainable product due to its high recycled glass content, which goes up to 80%. Clean solar energy is utilized as part of the manufacturing process of Ecowool insulation to reduce the carbon footprint. The energy savings from an insulated building also helps to reduce carbon emissions associated with heating and cooling the building, which is a big part of the source of energy consumption.

Glass wool is made from recycled glass while stone wool is made from natural volcanic rock (or basalt). In terms of product characteristics, glasswool can be made starting with lower density but stone wool’s minimum density is 40kg/m3 . Hence, glass wool has a lower service temperature of 450°C compared to stone wool’s 850 °C. They’re both categorized as mineral wool.

As both are made of non-organic material, both products are non-combustible. However, due to the resiliency of its fibers, glass wool products can be compressed packed which saves storage and reduce transportation costs and carbon emission due to transportation.

Although both products are glass mineral wool, the differences lie in the product characteristic and binding technology used to manufacture these insulation. Ecowool Classic is the yellow coloured, traditional glass mineral wool that caters to a wide range of applications.

Ecowool Brownie V2 sets a new standard for insulation as the right choice for contractors, builders and homeowners. These product range incorporates the revolutionary SensiTouch technology that provides additional benefits to the building performance that features a more superior product quality and better R-value.

Nevertheless, both range of Ecowool insulation products are engineered for the same purpose; to protect the environment, building and its occupants.

The few key factors that should be considered when choosing insulation products are:
1. Flammability; insulation products must be certified fire-retardant by BOMBA.
2. Thermal and acoustic performance based on test reports
3. Sustainability and product life-span; a longer product lifespan will generally be more cost-effective and environmentally friendly as it requires low to no maintenance, depending on the conditions of installed insulation
4. Not harmful for health; most of our time is spent indoors and hence, the building materials used must not contribute to any health effects to ensure the safety of building occupants

Health & Safety

Ecowool Insulation's glass wool have been classified as Category 3 by IARC (International Agency into Research on Cancer) and are not classifiable as carcinogens to humans, similar to black tea and nylon. Therefore, Ecowool is safe to manufacture, safe to be installed and most importantly, safe to co-exist with building occupants.

On top of being categorized as non-carcinogenic, Ecowool has ultra-low volatile organic compounds (VOCs) content, compliant with formaldehyde emission criteria set by major green certification bodies around the world. And this means, the quality of the indoor air will be unaffected with the installation of Ecowool insulation.

The Brownie V2 range of product have received recognition not only from the Malaysia Green Building Council as a GBI-certified insulation, it has also been certified as a two star-green mark as a Singapore Green Building Product. This recognition implies that our product is not just environmentally friendly, but a safe and healthy option as well.

Yes, Ecowool products are certified as BOMBA Class ‘O’. Glass naturally has a high melting point and it will not ignite fire spread which is essential to contribute as a passive fire system in a building.

Ecowool does not promote fire spread or any subsequent damaging situation for both buildings and people. This will indirectly give enough time for building occupants to escape unharmed from the building. When in contact with flame, Ecowool insulation will not produce toxic smoke, which are likely to cause suffocation or serious respiratory complications. This is particularly vital as toxic smoke inhalation can be equally life-threatening as burn injuries.


Yes, Ecowool can be installed according to the installation instructions and guidelines provided but we highly recommend home owners to work with experienced installers or contractors for best results.

The cost of insulating a residential unit depends entirely on the square footage of the target area, which is more commonly on the roof or the partition wall. Please connect with our team for a more detailed consultation on the products and costs, catered to your property’s needs.

A tiny house/ modular house in the Malaysian climate needs to be insulated for thermal efficiency, by reducing the penetration of heat from the outside. Tiny house is known to be energy-efficient but an effective planning on the right insulation installation can save you even more resources. The trick with tiny house insulation is finding the right mix between R-value and thickness; that’s going to keep your internal climate stable without taking up too much precious space. It is highly recommended to insulate the wall and the roof of tiny house/ modular house to ensure a comfortable living environment, especially during day time.


A Green Building refers to the term used to describe an environmentally-friendly type of property that has been certified based on some of the criteria and standards, set by the MalaysiaGBC. Green Building is designed to promote efficiency in energy use, water use, and sustainable building materials used for the construction of this building. The objective of a Green Building is to provide a more positive living environment that improves the health and well-being of residents throughout the building’s life-cycle. Ecowool’s Brownie V2 range of products is a GBI-certified building materials that will contribute to the development of a green building.

Commercial buildings that are insulated are inclined to be more energy and cost efficient, hence reducing the operating costs involving energy bills. With energy costs on the rise, reducing energy waste and consumption should play an integral part of a business operation. An excellent insulation system quality plays a vital role in reducing heat loss too, especially for businesses operating with hot pipes, hot surfaces or regulated temperature space. In short, insulation material is a cost-efficient investment that requires minimal to no maintenance, but comes with significant savings in the long run.

Essentially, all buildings will benefit from being insulated with a common benefit of fire safety features. But to give you a general idea, the following commercial structures are some of the most popular ones to insulate:

Barns and agro houses: In order to ease the farming process, temperature control of the property is essential. The right amount of insulation can help to regulate and optimize the living environment for the livestocks.

Warehouses: Warehouses, distribution centers and other industrial buildings are nearly always insulated for better thermal efficiency to optimize the storage environment and soundproofing.  

Offices: Having a conducive environment is a necessity for the corporate environment. Insulation installed in office walls and ceilings helps to limit the noise transmission between different rooms and levels within the office. The creation of a positive work environment promotes work productivity.

Retail centers, hotels, hospitals, airport, movie theaters: To meet the cooling demand and the acoustic requirement of these premises, insulation primarily helps to reduce noises from outside and inside of the building which is especially helpful if it is located in a heavily populated or high-traffic area. Thermal efficiency plays a vital role in maintaining the desired indoor temperature to ensure maximum comfort to customers and visitors.

Industrial HVAC

Some of the key metrics to consider when choosing a HVAC insulation includes the thermal conductivity, fire safety, condensation risk, sound absorbent properties.

The effectiveness of the acoustic performance of Ecowool insulation can be measured through the NRC result, which are proven to be more superior than foam or other non-mineral wool insulation. Ecowool can significantly reduce noise from the HVAC motors from travelling through the ducts, into the rooms.

HVAC networks and ducts can be the perfect pathway for spreading fire, hot gases and toxic smoke, in case a fire breaks out. A fire incident may spread more rapidly if the selection of the HVAC system materials are not fire retardant. With an effective fire resilient insulation to minimize fire spread, it will give enough time to building occupants to exit the building in case of fire.


Ecowool insulation needs to be installed with foil, for a single layer roof. It is highly recommended to only use a MS 2095 certified foil for optimum result.

Wherever possible, the installers should store the glass wool product in a dry, protected area. All packages should be elevated above the ground or slab, preferably on a flat surface, to prevent contact with surface water accumulations. Exercise care in handling to ensure best product condition.

In the event of water exposure or presence of excess moisture, the insulation performance of the glass mineral wool may be affected. Although Ecowool provides no sustenance for mold or fungi growth, proper product storage and installation must be practiced for optimum performance.

Ideally, we would recommend contractors to work with Ecowool product with additional water repellent treatment if the installation site are prone to wet conditions. Water repellent treatment is an additional protection formulated to withstand water exposure during installation to ensure optimal insulation performance.

Glass mineral wool are normally compressed into smaller pack, right after manufacture to be as space-saving as possible. Once unpacked for installation, the insulation will recover to its normal thickness and it is not recommended for the product to be compressed after the installation. A compressed glass mineral wool may affect the thermal and acoustic performance. To ensure best thermal performance, the thickness of the insulation needs to be maintained, without any compression. We recommend using a spacer to prevent compression after installation, for an optimum R-value.

The density for blanket product is 10 - 48kg/m3 with length availability that varies between 5m, 7.5m, 10m, 12m and 15m.

The density for slab or batts product is 20kg/m3 or 32kg/m3 with a length of 1.2m.

The density for board product is 32-96kg/m3 with dimension of 595mm - 1212mm.

Not suitable


Yes, highly recommended. Mineral wool insulation generally requires Z-spacer as it will provide space for the insulation to prevent compression besides providing support points for installation of roof cladding.

Science of Insulation

An insulated building envelope blocks the sound from traveling through the partition. Soundproofing works by adding extra obstacles which sound waves must travel through, reducing the energy of each wave until it is inaudible or dampened to an extent that it is barely audible. Having glass mineral wool installed within the internal partitions of your home gives you the ability to block internal and external sound transmission from one room or area to another.

STC refers to how well sound waves travel through ceilings and walls. A high STC indicates a better sound-proofing properties.

NRC rating tells you how well the insulation will absorb noises and sounds in a specific frequency range, to prevent the sound from reflecting back into the room.

While Ecowool can contribute to a better STC of wall or ceiling, it is the entire system with a combination of materials (e.g. wall board, studs, air space, etc.) that contributes to the overall STC performance.

An insulation’s R-value measures an insulating material’s resistance to conductive heat flow. Higher R-values correlate to an increase in insulating power. It is one of the key metrics that will determine the insulation’s thermal performance. To calculate the R-value, take the thickness of the insulation to be divided by the K-value (thermal conductivity). The R-value of thermal insulation depends on the type of material, its thickness, and its density.

Formaldehyde is a colorless, flammable, strong-smelling chemical that is commonly used for building and household products. Formaldehyde also occurs naturally in the environment as part of metabolic processes for living organisms. While short term exposure may cause slight irritation to skin, eyes, nose, and throat; high level of exposure may cause adverse health reactions.

The SensiTouch technology incorporated an anti-formaldehyde formula that are specially engineered to promote the quality of the indoor air. With SensiTouch technology, the Ecowool Brownie V2 insulation consist of ultra low volatile organic compounds, thanks to the significant reduction of formaldehyde exposure.
