Cladding support systems
Nvelope Cladding support systems are developed from the highest specification alloys making them capable of supporting even the most demanding façade materials including:.
HPL (high pressure laminate)
The firm holds extensive stocks of standard façade support systems including brackets, components, extrusions and accessories in all configurations. in-stock items are available for immediate delivery. project specific, cut profile lengths and bespoke systems solutions are available. we turn things around super-fast. The firm ensures that their rainscreen brackets and grid systems are safe and optimised with our design support service. The firm add to the design process with an almost infinite range of façade appearance and layout options.
All of the NVELOPE support sytems have achieved full British Board of Agreement (BBA) certification and are manufactured under the ISO 9001 quality management system.
Nvelope Cladding support systemss support almost any type of façade. There is a concealed fix (mechanical and structural bonding) and visible fix solutions are available. the systems selector will assist in matching the NVELOPE system to the chosen façade materials for your scheme.
The structural requirements of the system can be calculated to ensure the integrity of the installation. project material quantities can be accurately estimated and potential cost savings identified with straightforward access provided via completion of a project checklist.
the 2010 revision to part 'L' places specific emphasis on the performance of the building details and the additional losses through linear thermal bridging.
NVELOPE NV and NH brackets are pre-assembled with thermal isolators isolators help reduce thermal bridging in addition NVELOPE isolators prevent a chemical reaction occurring between aluminium brackets and lime in concrete frames.
The additional heat loss for each m2 of a detail is known as the PSI (ψ) value and this additional heat loss is dependant upon the type of detail, the thermal conductivity of the cladding materials and the quality of the detail design and installation.
NVELOPE brackets (and profiles) are manufactured in the UK to EN7559 production and EN12020-2 alloy and quality standards.
The aluminium density is 2.7kg/m3, or approximately one third that of steel. the low weight and high strength, malleability, simplicity of fabrication, corrosion resistance and good ability to conduct heat and electricity are some of the most important characteristics of aluminium.
Aluminium is very easy to recycle, needing only 5% of the energy required for primary production.
Aluminium alloys have tensile strengths of between 70 and 700n/mm2. in contrast to most steel alloys. at low temperatures the strength of aluminium increases, without any embrittlement of the metal. at high temperatures the strength decreases. at constant temperatures over 100°c consideration must be given to the effect on the structural strength of the material.
