Controlled Environment Solutions – Part 2

Part 2 – Composite make-up of panels

Our blog series on controlled environment solutions continues with a look at what components make up an insulated panel and how they are put together.

Hemsec began manufacturing insulated panels way back in 1928 as discussed in Part 1 of our blog series, and we have continued to play a key role in innovation in the industry, so we know a thing or two about them. Today, the COVID-19 public health emergency has put into focus the requirement for urgent buildings and NHS projects, using structural insulated panels, metal and timber-faced. Our aim in the series is to give you useful information.

What are insulated panels made from? How are they made?

It’s important to explain the manufacturing capabilities of an insulated panel and how they are made.

All of our galvanized steel faced panels are auto-adhesively bonded together during the manufacturing process, where the application of pressure injected liquid foam expands and fuses between top and bottom coated steel facings.

The insulated core is made from Polyisocyanurate (PIR), Hemsec use this as it has superior insulating qualities when compared with the other types. This closed cell chemical technology ensures that Hemsec panels are extremely versatile, incredibly airtight, can resist moisture and are impervious to water.

There are an array of different colour and steel finishes from various suppliers to meet all project requirements; the facings are completed with our Smooth, Microrib or 100 Rib detail facing options. Panels are pushed together using an engineered tongue and groove joint system, meaning no unsightly joins need to be formed. And the panels are strong, so you do not always require supporting frames, meaning it’s clean, attractive and cost effective.

We have the ability to form rebates and thermal breaks in our panels during the manufacturing process. Rebates are particularly suited for internal Wall to Ceiling junctions, where the insulated ceiling panel will sit upon a horizontal landing (rebate) at the top of the insulated wall panel, these rebates are cut to suit the thickness of the ceiling panel and the landing depth is 50mm (80mm thick wall panels have a 40mm landing depth. 50mm N/A).

Thermal breaks are suited for internal Wall to Floor junctions, particularly for Freezers. A 20mm deep saw cut is made at a height of between 80mm to 300m from the base of the panel.

What are insulated panels used for?

Our controlled environment panels are used in many industry sectors as well as construction; they are amongst the strongest and most thermally efficient panels available anywhere in the world. It’s no wonder that with Hemsec, our clients tell us “you know what you get” – providing them with absolute confidence when they buy and use our panels.

Being able to control the temperature and humidity of an environment is nowadays crucial in a wide range of industries and sectors, particularly health at the present time. Applications include:-

  • Healthcare product manufacturing (Including hygienic/clean rooms and temperature controlled environments)
  • Health services (theatres, treatment rooms, and pharmaceutical storage)
  • Accommodation (temporary isolation rooms, home-working pods, and hospital wards)
  • Food manufacture (food safe freezers, chillers and ambient areas), storage, and distribution
  • Warehousing and data centres

These are only selection of environments which require flexible yet robust solutions. Hemsec insulated panels are made for this very purpose, in a variety of thicknesses and finishes, giving plenty of scope for project-by-project customisation.

What are the benefits of insulated panels?

They are versatile and strong enough to be used as internal walls, external walls, partitioning and ceilings as well as high performance doors. They are also resistant to fire, which is clearly an important factor in every sector, so all our panels are subject to intensive testing to meet the highest safety standards.

Here are just a few of the significant benefits that insulated panels can provide:-

  • Superb thermal performance and energy efficiency
  • Temperature control (ambient, chilled and frozen, from – 40°C to +60°C)
  • Fire resistance
  • Quick installation due to precision jointing
  • Hygienic steel-faced coatings
  • Eco-friendly and cost effective

Let us look now at why Hemsec’s panels are the industry leaders.

What industry standards are used for the insulated panels?

Trust in our products is extremely important to Hemsec. That’s why we have invested over the years in BS EN standards and CE marking, together with rigorous testing to ensure that our panels consistently meet your expectations, needs and the highest standards.

Resistance to fire is priority number one. Hemsec’s insulated panels guarantee up to 60-minute fire performance with both Loss Prevention Certification Board (LPCB) and Factory Mutual (FM) approved certifications.

Taking responsibility in today’s environment is similarly important. Hemsec is committed to achieving the ultimate goal of carbon neutrality for all our products within the built environment, manufacturing insulated panels which are energy efficient, highly effective for temperature control and cost little to run.
