Devana Insulation offers multiple solutions to create perfectly insulated masonry-constructed buildings. We primarily use injected insulation for masonry constructions with products that ensure high performance whilst being suitable to the building’s structure.
In order to insulate masonry cavity walls, Devana will use Blown Mineral Wool insulation. This cavity wall insulation is silicone treated, non-combustible, and high performance. It is injected into masonry cavity walls after the wall is constructed. We install into newbuild properties where it is much more efficient than alternative methods. It’s very quick so saves time in the build schedule; bricklayers can concentrate on their specialist skill; there is no need to buy material to store on site getting damaged; and there is no waste as we only use what we blow in.
Devana uses Supafil 34 Glass Mineral Wool for masonry external walls. This insulation has excellent thermal performance properties. At a minimum installation density of 25 kg/m3, the thermal conductivity of this insulation is 0.034 W/mK.
Supafil 34 Cavity Wall Insulation has a high content of recycled material and no known threat to the environment, zero Ozone Depletion Potential, and zero Global Warming Potential. The reduced requirement for heating with insulation also benefits the environment.
Tests on this masonry cavity wall insulation confirm that there is no transmission of water to the inner leaf or moisture transmission by capillary action across the cavity. Furthermore, Supafil 34 does not add to the risk of water penetration
For separating party walls, Devana Insulation is able to use Supafil Party Wall Glass Blowing Wool Insulation. Heat can often be lost through a party wall cavity due to air exchange between the party wall cavity and the external environment. Our insulation solution can be installed into new or existing masonry cavity party walls in order to prevent this party wall loss of heat
Supafil Party Wall has been proven to effectively eliminate the air movement that causes party wall bypass in both new and existing buildings. Within existing homes, installation of this insulation will not compromise acoustic performance. It can contribute to a zero effective U-value to be claimed in SAP calculations.
This insulation has no known threat to the environment as well as zero Ozone Depletion Potential and zero Global Warming Potential. It is made from recycled glass that is inert, therefore will not react with insulation to wiring or metal wall ties.
As the product is formed in-situ, we are able to accommodate variations in cavity width. The installation is quick and easy with our injection process. This installation is easy to combine with other masonry construction insulation such as external walls.
Devana uses Blowerproof Spray VCL, which has been extensively and independently tested for suitability on a variety of materials
including brick and masonry.
The Devana Process
Devana’s installation of Spray VCL offers complete peace of mind. By using a dual process with brush and spray methods, Devana can guarantee excellent airtightness. All gaps and junctions are filled with fibre-reinforced polymer and then the whole area is sprayed with the membrane.
This Spray VCL is VOC free, water-based, flexible, and has fibre reinforced polymers. It is a unique and sustainable solution for the production of airtight building connections with a durable highly adhesive spray VCL.
Our expert installers can ensure a complete and secure coverage with great performance. The installation process is very quick with some cases taking less than a day.
