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 Metal Insulated 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 Thickness (mm) | Min. Panel Length (m) | Thermal Transmittance U W/M2K * | Weight Kg/m2 (0.5/0.5) |
---|---|---|---|
50 | 2.4 | 0.39 | 9.60 |
80 | 2.0 | 0.25 | 11.00 |
100 | 2.0 | 0.20 | 11.60 |

150 | 2.0 | 0.13 | 13.40 |
175 | 2.0 | 0.11 | 14.40 |
200 | 2.0 | 0.10 | 15.70 |
* Thermal transmittance based on a mean thermal conductivity value of 0.02038 W/mK.
* Pressure/Suction load type.
** Spans specified are not necessarily as per fire test conditions. Refer to the Hemsec Fire Rating Matrix document for further detail, available to download from our website.
All spans are based on single span conditions with 0.5mm internal and external steel faces.
Shaded cells denote dark coloured steels, un-shaded denote light coloured steels.***
Span lengths vary between dark & light colours due to differing UV absorption/reflectivity on the panel face giving varying deflection criteria (see below for Surface Temperature Conditions used in calculations).
*** Please refer to the ECCS document European Recommendations for the Determination of Loads and Actions on Sandwich Panels No136 2015 for examples of temperature loads. This document shows the likely maximum surface temperatures specific colours can have with the full effect of the sunlight. Please also refer to BS EN 14509:2013 page 132 for further details.
Surface Temperature Conditions:
Light coloured steels RG = 40-74 T outside face = +65°C
Dark coloured steels RG = 8-39 T outside face = +80°C
(Where RG is the degree of reflection relative to magnesium oxide = 100%)
Table Data Based Upon:
1. Values have been calculated in accordance with BS EN 14509 : 2013 self-supporting double skin metal faced insulation panels.
Also in accordance with European recommendations for design of composite sandwich panels ECCS Doc 115 : 2001.
2. The following deflection limits have been used. Pressure and Suction L/100.
3. Sufficient numbers of fasteners (through fixed) are required to secure panels to the structural frame. Typically 3 no. per panel end and at purlin/primary steel positions as quantified by a structural engineer.
4. The minimum bearing width on panel ends to be 100mm per end, please consult Hemsec for bearing widths less than this.
5. Wind loads are working loads (unfactored).

Panel joint air-tightness = 0.01 m3/m2/hr at 50 Pa when tested to EN 12114 in accordance with BS EN 14509: 2013.
All panels have a predicted figure weighted sound reduction Rw = 26dB.
Reaction to fire:
Polyester coated PIR sandwich panels have a performance in accordance with EN13501-1:2007 + A1:2009 of B s2 d0.
Plastisol coated PIR sandwich panels have a performance in accordance with EN13501-1:2007 + A1:2009 of C s3 d0.
