Sandwich panels or trapezoidal sheet metal \u2013 this question always comes up just before the quotation is drawn up. The cladding accounts for 20\u201330% of the hall\u2019s cost, so the decision between \u201esandwich panels or trapezoidal sheet metal\u201d can increase or decrease the budget by several tens of thousands of zlotys. At MatBud, our role is to advise you on what really pays off \u2013 not the most expensive solution, but the best one for your specific application. Below, we present four key criteria that will help you make an informed choice of cladding.<\/p>\n

\u00a0<\/p>\n\n

Cost \u2013 three-fold difference<\/h2>\n

\u00a0<\/p>\n\n

Currently, a sandwich panel is approximately 3 times more expensive than trapezoidal sheet metal per m\u00b2 of cladding. For a 500 m\u00b2 hall, this difference can amount to tens of thousands of pounds. However, be aware \u2013 this is not an argument to always choose sheet metal. Sheet metal is bare cladding without insulation, whereas a sandwich panel is a finished, insulated wall. If you need to insulate the hall anyway, adding mineral wool with a vapour barrier and flashings will quickly eliminate the price difference, and often even turn it in favour of the panel.<\/p>\n

\u00a0<\/p>\n\n

Good news: MatBud constructions are designed with a load-bearing capacity reserve for sandwich panels. You can erect a hall with trapezoidal sheeting today, and in a few years \u2013 when the use changes \u2013 replace the cladding with panels without altering the structure. This is a real saving for investors who want to start cost-effectively but not close off the possibility of expansion or repurposing the facility.<\/p>\n

2. Thermal Insulation \u2013 The Key Distinction<\/h2>\n

\u00a0<\/p>\n\n

Corrugated metal sheeting<\/strong> This is bare sheeting, without insulation. It's suitable for unheated halls where the internal temperature can be close to the external one. On hot days and frosty nights, the difference relative to the surroundings is literally a few degrees.<\/p>\n\n

In turn sandwich panel<\/strong> It's like a sandwich, consisting of two metal sheets and an insulating core (PIR, PUR or mineral wool). The U-value is from 0.18 W\/(m\u00b2\u00b7K). The hall is immediately ready for heating or cooling.<\/p>\n\n


The rule is simple: if a person is to work in the hall for 8 hours a day in winter, and a constant storage temperature is to be maintained \u2013 the panel is definitely the best choice. If it's a garage for agricultural machinery, a straw store, or an independent roof \u2013 corrugated sheeting will do the job for a fraction of the price.<\/p>\n

3. Applications \u2013 what, where, and why it works in practice<\/h2>\n
