Rockwool stone wool products absorb a very little water from the air. 4. BEIJING NEW BUILDING MATERIAL(GROUP) CO., LTD. ADD: Building 4, Interwest Business Center, No.9, South Road Shouti Haidian District, Beijing … 37-41 45966 Gladbeck . ROCKWOOL insulation can easily be cut with a long bladed knife or insulation saw available from DIY/Builders Merchant outlets. Is my house suitable for cavity wall insulation? It is sourced from abundant lava deposits of volcanic rocks which are melted in a cupola furnace like a controlled man-made volcano. Check it out. ROCKWOOL insulation is classified as A1 non-combustible however, products need to be tested for the specific application they are proposed to be used for and must be tested to perform for the fire resistance period required. Can I achieve a BREEAM insulation credit when specifying a Green Guide ‘C’ rated material? ROCKWOOL products are destined for a wide variety of applications needing different densities, each of which is designed into the product at the manufacturing stage. Can you use that in walls? The requirement of 150mm above ground level is to reduce the incidence of ‘splashback’ from rain and to ensure a minimum amount of elevation above standing water that may occur in periods of heavy rain, etc. Provided the masonry wall width is at least 250mm and the insulation is inserted under at least 10% compression, the 60-minute requirement of Building Regulations will be met. This is ‘Good Practice’ guidance for most buildings built approximately within the last 30 years. Seit Jahren arbeitet die ROCKWOOL Gruppe weltweit daran, die Quote der recycelten Steinwolle stetig zu erhöhen. Can ROCKWOOL be installed underneath site concrete or screed? Each insulation product in the building is calculated as follows: Once this has been applied, along with the Green Guide rating points for each of the insulation materials used, you will have values for the total area weighted thermal resistance and the Green Guide rating correction. It is ROCKWOOL Group policy to adhere to environmental standards better than national or local requirements. To see the full build-up, please refer to the ROCKWOOL FLEXI Datasheet. Comprised of a high-density outer layer and a lower-density sub-layer, Dual Density products provide compressive resistance, excellent sound absorbency and many other benefits for different applications. Should loft insulation be fitted between the joists or be placed over the joists? There is no single answer to this. Brass instrumentalists are taught that higher notes require faster air while lower notes require more air. Doubling the thickness results in an almost 400% increase in absorption at 125 Hz, while doubling the density is only about a 20% - 50% increase. - [150kg/m3] In my small home studio I have already made 10 bass trap panels. Density. We do not recommend that the insulation product is submerged in water. Density of the rockwool is 150kg/m3 and each panel is very heavy. What products do you recommend? Yes, ROCKWOOL insulation has natural inherent properties for thermal, fire and sound which is present in all products. Using a fidget spinner to rotate in outer space. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Do I need to wear any protective clothing to fit ROCKWOOL insulation in my loft? This allows for open airflow between the 'tips'. Two layers of gypsum board mated together has a higher STC than one layer. Accurate understanding of the physics of sound? The ROCKWOOL Roll is supplied in 1200mm widths with cutting guides on the packaging for 600mm or 400mm centres for ease of use as these are the most common widths. If you do get ROCKWOOL on your skin, it is recommended to rinse with cold water. Can I use my Sound Insulation slab for a thermal application or do I need to buy the Thermal slab?
