Six aspects that always apply.

Before dismantling is carried out, it is recommended to carry out the preparatory work below. On the one hand, these steps help to estimate the reuse potential. On the other hand, they contribute to the traceability of the insulation, which can increase new users' confidence in the insulation.

• Analysis of plans and documents (as-built)

• Dismantling trials

• Test drillings to detect hidden materials and connections

• Drawing up a reuse inventory

Not all insulation will be reusable. If one of the points below applies to your construction site, you are advised not to dismantle the insulation with a view to reuse.

• Presence of asbestos

• Presence of tar

• The safety of the dismantlers cannot be guaranteed

• The insulation is fully bonded

• The insulation shows water damage

• The insulation shows a lot of damage

Besides the deal-breakers, there are also considerations that can affect the reuse potential. If one or more of the considerations below apply, you are advised to assess for yourself whether or not it is worthwhile to dismantle the insulation with a view to reuse.

• A limited quantity of insulation

• Insulation with a small thickness or non-standard dimensions

• The possible presence of F-gases / CFCs

• Insulation that is difficult to access

• Insulation that is difficult to handle from a logistics point of view

• No space to store the insulation

• Time and efficiency

• Selective vs traditional demolition

• A new destination

During storage and transport, it is important that both the information about the insulation and the condition of the insulation are preserved. Pay attention to the following:

• Dry and well-ventilated storage without excessive exposure to sunlight

• Store the insulation on offcuts (for boards), on pallets, in boxes or in bags

• Do not excessively compress or deform

  • Boards that are larger than their pallet can start to bend over time

• Protect the insulation with plastic film and/or cardboard corner profiles

Always make sure the dismantling can be carried out safely. Also think about suitable personal protective equipment (PPE). Preferably wear work gloves, a dust mask of at least type FFP2, appropriate workwear and, if necessary, safety glasses. Limit dust generation during dismantling and, if possible, work in a well-ventilated environment. These precautions help to limit exposure to dust, fibres, particles and any contaminants until the material has been correctly identified and assessed.

After dismantling, it is important that the insulation is sorted into uniform lots and the information is collected per lot. Lots are classified on the basis of:

• Type of insulation (insulation type, manufacturer, ...)

• Thickness

• Current condition (A, B and C quality)

Elements with a high moisture content are collected in a separate lot. The moisture content can be checked with a moisture meter. During dismantling, damp boards can be distinguished from dry ones by their weight.
