For building owners that are considering to re-clad or over-clad their building.
Many building owners, in the wake of what was Grenfell, feel emotionally and morally obliged to ensure their tenants are not at risk of a fast-spreading fire, induced by combustible panels on the outside of their building.
Sadly, combustible panels are widespread in tall buildings all across the United Kingdom because they were specified by architects or project managers, essentially because of their aesthetic appeal, versatility and relatively low cost.
Replacing panels on every building is a mammoth task, simply because every building is unique and requires a unique solution.
However, the concept of remedial works needs to consider several things that we have listed out below.
Here are the things you need to consider
Are you over-cladding or re-cladding?
Re-cladding is different from over-cladding.
Over-cladding is a method used to add an exterior layer of insulated cladding (like a curtain) to an aged, usually concrete tall building, in order to prolong its life and improve its energy efficiency, protection against weather conditions and, ofcourse make it more attractive to look at.
Re-cladding, on the other hand, means you already have a cladding barrier in place and you are looking to replace it. That means the cladding substructure frame is already in place and windows and door entrances have already been upgraded and/ or framed.
Alusafe can provide solutions for both scenarios and you can discuss your project specifications
with one of our experienced technical support team on 02035824658.
So What do you need to consider when re-cladding your building?
The remedy is simple but requires the following checks. And each of these can have an impact on your
cost to replace the cladding to non-combustible versions.
Is your existing substructure strong enough to carry the extra weight of non-combustible ACM panels?
The existing façade frame may be too weak to secure panels to the building. This would be tested to ensure it could meet building regulation standards.
Does your existing substructure meet fire safety standards?
Each element of your façade system must be fire resistant, in order to fulfil building regulation standards. This means things like cavity barriers will need to be installed to close the edges of cavities, around openings and in line with every compartment wall.
Does the existing substructure minimise moisture within the façade system?
Building structure, cladding and insulation should be designed to keep moisture to an acceptable minimum. This means including copings, flashing and drainage in the design of the new system to prevent penetration from rain. Insulation materials should not become wet, especially during construction. This can multiply the weight the substructure needs to carry.
Final considerations need to be given to increasing the ventilation inside the apartments because of the increased chance of condensation. Your building will perform better because the new aluminium composite panels, along with the new insulation will prevent air leaks. But this leads to potentially higher condensation in the apartments, hence, you may have to install additional ventilation.
