Sandwich Panel Replacement and Single Skin Sheet Replacement
Sandwich panel replacement and single skin sheet replacement are needed when the cladding material itself has failed. Single skin sheets corrode through from the top or from condensation beneath. Sandwich panels fail differently: the metal skin separates from the insulating core, water enters the core, and the panel loses its stiffness and its insulation value.
Leak Lock Insulation Contracting replaces both types on industrial and commercial buildings, matching the profile and specification of what is already installed. This page covers the materials and options in detail. For a general overview of damaged roof and wall panels, see our roof panel replacement service.
How Sheets and Sandwich Panels Fail
For example, clients contact us for one or more of the following reasons.
- Rusted-through single skin: pinholes and perforation along laps and fixings.
- Delaminated panels: skins bubbling or lifting from the core.
- Waterlogged insulation: panels heavy with water and dripping long after rain.
- Crushed panels: dents from foot traffic or stored items.
- Condensation damage: corrosion on the underside of uninsulated sheets.
- Fire or heat damage: panels distorted by a local incident.
Our Sheet and Panel Replacement Options
Single Skin Roof Sheets
Profiled sheets replaced to match the existing roof.
Roof Sandwich Panels
In addition, insulated roof panels replaced with matching thickness.
Wall Sandwich Panels
Damaged insulated wall panels changed.
Single Skin to Sandwich Upgrade
Similarly, uninsulated roofs upgraded to insulated panels where the structure allows.
Partial Replacement
Only the failed bays replaced to control cost.
Full Re-Sheeting
Also, complete replacement when failure is widespread.
Our Sheet and Panel Replacement Process
Because every site is different, we adapt these steps to your sheet & sandwich panel replacement project.
- SurveyBefore anything else, failed sheets or panels are identified and the profile recorded.
- SpecificationThen, panel type, thickness and finish are agreed.
- RemovalAfter that, old material is removed safely, bay by bay.
- InstallationAs soon as that is done, new sheets or panels are fixed and lapped.
- SealingFinally, laps, fixings and flashings are sealed.
Materials & Methods
Single skin sheets are profiled metal sheets fixed directly to the purlins. Sandwich panels consist of two metal skins bonded to an insulating core, such as PU, and are specified by thickness. We match the existing profile and panel thickness so that laps and flashings fit, then seal the new laps with EPDM membrane.
In short, the work includes the following.
- Profiled single skin metal sheets
- Insulated sandwich panels with PU core
- Matched profile and thickness
- EPDM-sealed laps between new and existing

Sheet & Sandwich Panel Replacement FAQs
Questions about single skin sheets and sandwich panels. Also, you can call us with any other question.
A single skin sheet is one layer of profiled metal. A sandwich panel has an insulating core between two metal skins, so it insulates as well as covers.
Not reliably. Once the skin has separated from the core, the panel has lost its strength and should be replaced.
Often, yes. Sandwich panels are heavier and thicker, so we check the structure and the flashing details first.
We match profile and thickness. Colour is matched as closely as current supply allows.
Yes. They are inspected once the old sheets are off, and replaced if corroded.
