At a glance
Hemsec External helps create more usable space in a building, whilst providing insulation and fire resistance.
- Designed with exceptional inherent strength which reduces the need for secondary supporting steelwork.
- Lightweight, factory engineered and fire resistant.
- Improves the appearance of a building.
- 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 External 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…
|Min. Panel Length|
U W/M2K *
* 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).
External Steel Facing:
- Micro Rib (as standard).
- Smooth (on request only).
Internal Steel Facing:
- 100 Rib.
Hemsec will always strive to push the limitations of our product range. We do this by testing them more thoroughly than even the most rigorous accreditation requires us to do so; underpinning our promise of quality.
The technical specifications outlined above were delivered from successful demonstrations, performed to the test standards set out by our accreditation suppliers. You can relax knowing that the business risks associated with key projects are reduced by us working directly with these bodies:
- Loss Prevention Certification Board (LPCB)
- Factory Mutual (FM Approval)
- BS EN Standards
- Conformité Européenne (CE Marking)
