Product Description

ROXUL Safe n Silent Pro is a stone wool insulation product for use in interior wall partitions of residential wood and steel stud construction where superior fire resistance and acoustical performance are required. This non-combustible, lightweight product has excellent acoustical dampening properties and is dimensionally stable which makes it ideal for friction fit into walls, ceiling and floor applications. The product is chemically inert; therefore it will not promote corrosion.

Rockwool™ is a nature-based insulation made of volcanic stone, a safe and sustainable material that continues to perform and lasts throughout the lifetime of the building. It is designed and manufactured to achieve excellent acoustic insulation performance in all types of drywall partition configurations.

This product is designed for interior wall, ceiling and floor applications. ROCKWOOL™ Safe‘n’Silent Pro is recommended to be used for drywall partition applications in recording studios, home theaters, auditoriums, hospitals, cinemas, schools, offices, residential and industrial buildings. It may be used for metal stud partitions for easy installation, keeps its shape over time without sagging or slumping in the wall cavity.

Sealed hollow cavities in ceiling and walls act as a “drum” with an amplifying effect on noise, especially of certain wavelengths. It is very common in India to use false ceilings with empty cavity. Using Rockwool acoustic mineral wool lessens the sound energy ‘bouncing’ around inside the cavity and creates a quieter environment. This is easy to retrofit by opening the ceiling at a few points and inserting the rockwool.

Absorption Performance:

Water Repellency

Safe’n’Silent Pro is both water repellent and moisture resistant (tested under EN1609). The product repels water even when exposed to temporary splashing of rain water at construction site and still able to maintain its shape over time; thereby delivering maximum noise and fire protection. Moisture and nutrients are necessary conditions for fungal growth. Since more than 95% of this product is made up of inorganic fibres, there is little nutrient source to allow fungal growth. Hence, it does not cause corrosion of the metal studs nor promote fungi growth within the wall cavity.

Fire Protection

Few insulation can take the heat like we do – with the ability to withstand temperatures of over 1000°C without melting according to DIN 4102-17. Safe’n’Silent Pro is non-combustible and achieves the highest European fire classification, A1, according to EN13501-1. This means that it can effectively impede the spread of fire and provides the critical extra minutes for occupants to escape from a room or building. With its fire retardant properties, Safe’n’Silent Pro also does not contribute to fire load within the building and complies with ASTM E84-10 to achieve Flame Spread ‘0’ and Smoke Development ‘5’ that surpass NFPA Class A requirement.

Easy to Cut

It is also simple to cut Safe’n’Silent Pro to size with a serrated knife, for a fast and easy installation between studs, around electrical boxes, pipes, wiring, ductwork and even between studs and joists of non-standard widths.

Sag free & tight fit

The very nature of stone wool makes Safe’n’Silent Pro a wise long term investment that works continuously without requiring any maintenance. The higher density material provides superior sag resistance and fit when mounted within a frame or wall cavity. It can be easily cut and trimmed for the best possible fit into the partition wall cavity, assuring there will be no gaps that may compromise the performance of the system. Safe’n’Silent Pro keeps its shape over time without sagging or slumping in the wall cavity. All these ensure a partition wall system that protects its occupants against noise and fire for the lifetime of the building.

Fast and easy installation

Safe’n’Silent Pro is fast and easy to install, helping to reduce the time taken and labour needed for installation work, hence increasing overall speed of construction. Working with Safe’n’Silent Pro is easy and can be done in 3 simple steps:

Our head-office is in Mumbai; however, we don’t have a showroom or physical stores. We're an online company - we distribute our products online all over India via a distributed warehousing system - we have warehouses in 8 locations. Since our products are technical and used for solving specific acoustic problems, they do not attract walk-in customers. If you want to buy our products, just place your order online or reach out to us via the contact forms.
We do not offer Cash on Delivery. Our products are extremely large and bulky - you can fit a human being into most of our boxes. As a result, one of the highest costs in running this company is the money paid to courier companies like Fedex, XPressBees, etc, which runs into crores of rupees annually. If we allowed COD and the buyer changes their mind and refuses to pay during delivery, we incur double shipping costs (a) for sending the product to the buyer + (b) for shipping the product back to our warehouses. In some cases, this may be more than the value of the product itself. For this reason, we find it impossible to offer Cash on Delivery.
We follow maximum transparency in showing you actual delivery dates at a product level. The exact delivery dates are visible on each product page, cart page, checkout page, as well as your order confirmation emails. Once your order is shipped, regular shipping updates are provided via SMS.
We supply products only. We're an ecommerce company and our focus is on importing, distributing, manufacturing, and supplying a wide range of technical isolation & acoustic products across India. For installation you can engage local contractors / carpenters. Please contact us if you need specific information on installing any product in our catalog.
We accept returns upto 30 days from the date of receipt of product. If you need to return a product, just contact your sales representative and we will arrange a reverse pickup via Fedex. Your refund will be processed within 3 days after we get it back. We charge a 15% fee for restocking the product so this is subtracted from your refund. This is waived off if you have not removed a product from it's original packing and are returning it unused.
Your order could be in several spots... our warehouse, our custom-shop manufacturing units, anticipating dispatch, with the courier on its way, or conveyed. The principal thing to check is have you had your dispatch email? If yes, at that point it's en route. You can track your order by clicking your tracking link from that email. In the event that you haven't got your dispatch email within a week of placing your order, please do contact us.

Installation Materials 3. Product Samples To minimise colour-fading of acoustic foam products due to exposure to oxygen and ultra violate light, carbon is employed during the colouring process. This does not guarantee the colour fastness of the foam component and you should expect the appearance to change over time. Colour fastness is not covered under the Warranty. This warranty does not cover damage to furniture or equipment caused by contact with or destabilization of the foam components or adhesives and hardware used for installation. Care should be taken when placing the product on finished wood surfaces or other surfaces to ensure there will not be a chemical interaction between the surface finish and the foam component.
