Hemsec Control Smooth Metal Faced Insulated Panels
This cost-effective, internal food-safe panel with steel facings is ideal for refurbishment projects.

  • The thinnest panels in our Control range, available in 50mm and 80mm thicknesses.
  • Long cover width of 1155mm helps reduce your panel quantity requirements.
  • There are no unsightly joins and you don’t need supporting frames, so it’s clean and attractive.
  • Control in the 50mm thickness is especially suited for use as a ‘liner’ panel to replace PVC single skin.


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 Preparation.
  • 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 Control 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…

Difference *
Weight Kg/m2 (0.5/0.5)

* Max. Single wall spans (horizontal and vertical) are based on a combination of stress and deflection of 0.3kN/m2 with both walls and ceilings on a temperature difference (between internal and external environments) of 18°C, typically encompassing chill and ambient production zones. For temperatures and structural loadings beyond the above stated, consult Hemsec.

Max. Single ceiling spans are based on 0.9kN point load at mid-span and 0.25kN/m2 UDL (Hemsec strongly recommend referring to our Ceiling Care document for greater detail). Minimum bearing/support of 50mm at panel ends. Consult Hemsec for further information on permitted bearing loads and edge supports.

Panels are manufactured to bespoke lengths starting at the stated minimums above; maximum lengths stated may be increased upon referral to Hemsec up to a manufacturing capability limit of 15m**

** Hemsec should be consulted on any panel lengths greater than the maximum stated in the above table due to the difficulties faced when handling and on installation. Spans greater than 8.00m(Walls) / 5.37m(Ceilings) typically captured within the Control 30 / Control 60 product ranges.

*** Calculated using the method required by the Building Regulations Part L2 (England & Wales) and Building Standards Part J (Scotland).
Thermal transmittance based on λ mean = 0.02038 W/Mk.
