Hemsec Carrier Smooth Metal Faced Insulated Panels
Hemsec Carrier is an external fire-resistant panel, which allows for you to apply a range of external cladding options.

  • Ideal solution for structural, low-air permeability and thermal ‘support’ for roofs or walls.
  • Enhances the energy performance of the building and reduces CO2 emissions.
  • A superior, smooth surface over long panel lengths, which can take external finishes such as zinc, aluminium, standing seam and rainscreens.
  • Full thickness range from 50mm (U value of 0.39) to 200mm (U value of 0.10).


Hemsec Control panels are ideally suited for use in your internal refurbishment projects and for forming multiple suites of rooms. As the thinnest panels in our range they are not only the most cost effective solution but offer fantastic thermal performance alongside unrivalled wall and ceiling spans.

Our 50mm thick panels are especially suited for use as lining walls replacing the likes of PVC single skin products, avoiding unsighlty joins and supporting frameworks resulting in a clean, attractive and aesthetically pleasing finish.

These temperature controlled solutions are typically used within the food and drink industry, for applications such as:

  • Chilled Storage.
  • Food Processing and Preperation.
  • Storage and Warehousing.
  • Retail solutions.


We aim to provide you with easy to follow and relevant technical information, suited to the vast majority of applications. 
Whilst we are confident the below data will help you specify, design and build your project using our Hemsec Carrier panels, we always encourage further conversations around your project specific requirements. This can make the most of our panels capabilities, allowing us to tailor our technical details with a project specific guarantee. Its good to talk during the early stages of your project…

Span Information:

Span capabilities for Hemsec Carrier panels are determined on a project by project basis and require specific site data to be checked by a qualified structural engineer. Please contact Hemsec during the early stages of the projects design phase to make the most of the panels capabilities.

All designs should be qualified by a third-party structural engineer who can then determine the appropriate arrangement of tophats and their fixings, Hemsec can provide the names of such structural engineers upon request.

Ideally the preferred solution is to fix vertically laid tophats to the panel face with through fixings into rails behind as shown on the detail, helping hand brackets are then fixed to the tophat, this approach eliminates any localised forces from the bracket into the outer skin of the panel.

If cladding rails are not available, then it may be possible to fix the vertical tophats into the outer skin of the panel with special fixings, it is advisable to keep the tophats in a vertical orientation on all applications as this reduces the loads in the fixings considerably compared with tophats laid horizontally.
