Hemsec Control Smooth Metal Faced Insulated Panels
Widely used for Clean Rooms and Pharmaceutical environments.

  • A solution for demanding spans, where Honeycomb systems are length restricted.
  • Superior smooth surface finish with no unsightly joins, so it’s clean and attractive.
  • Long cover width of 1155mm helps reduce your panel quantity requirements.
  • Gives excellent thermal insulation and is a Zero Ozone Depletion Potential product.


Hemsec Clean 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 Clean 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…

Panel Data

Panel Thickness (mm)Min. Panel Length (m)Max. Single Span Wall Height * (m)Max. Single Span Ceiling * (m)Thermal Transmittance U W/M2K ***Deflection Temp. 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. For temperatures and structural loadings beyond the above stated, consult Hemsec.

For specific fire rated spans, please refer to the Hemsec Fire Rating Matrix document.

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.

*** 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.

Cover Width:


Insulation Core:

A rigid Polyisocyanurate insulation core, provides the following benefits:

  • Closed cell.
  • HCFC free.
  • Zero ozone depletion potential (ODP).

Panel Joint:

Tongue and groove panel joint achieves excellent vapour resistance and thermal performance.
