Insulated Metal Roofing: Lots of Choices for All Types of Building Needs
Metal roofing is the default roofing for a very large range of very different types of building. It’s cheap, it’s reliable, it’s long-lasting – And it NEEDS proper insulation. Metal roofing conducts heat, and that heat must be managed properly. Modern buildings are nearly all climate-controlled, and these buildings (and their owners) don’t need added expensive demands on power for heating and cooling.
Insulation is the obvious, efficient, fix for these potential problems. The problems themselves are worth a look, to understand the issues in more depth:
1: Metal gains and loses heat rapidly. Metal can absorb a lot of heat, and that heat is almost like having a gigantic bar radiator on your roof, if the heat isn’t dissipated. (If you’ve ever worked in an un-insulated metal building, you’ll understand exactly how astonishingly hot that can be. The heat is positively gruesome, in a hot Australian summer. Lack of insulation can also make buildings extremely cold in winter with added heating costs, too.)
2: A lot of heat and building structures don’t mix very well at all. Whatever the building, sudden heat can warp supports, damage interiors, and damage structures.
3: Power consumption can cost a LOT of money. In a big building, if the air conditioning is constantly compensating for heat buildup, you’re looking at a very ferocious power bill. You may not be too surprised to learn that this seemingly obvious fact was discovered the hard way. The constant temperature variations don’t do your air conditioning a lot of good, either, adding extra wear and tear to temperature controls.
Why Metal Roofing Insulation Is Best Building Management Practice
Roofing insulation does more than protect your building. It also protects your metal roofing. Heat transfer from metal is continuous, to the nearest cooler temperature region. That’s why insulation protects your building, but there’s a less obvious benefit – By acting as a firewall against heat transfer, insulation means that the metal roofing transfers heat outside to the surrounding air, not inside to the building. This also means the roof loses heat more quickly.
This process prevents excess heat buildup in the roofing metal. That’s a very good effect, because metal expands and contracts when heated, and expansion and contraction can damage the metal. If you’ve seen those warped rail lines in recent summers around Australia, that’s a pretty good example of what your roofing insulation is preventing.
Expansion and contraction also affects roofing joins and can literally pull apart a roof over time. It’s no coincidence that you see slipped metal panels on some roofs; the heat has simply expanded and contracted to the point that the roofing falls apart. Another good reason for insulating your metal roof, for sure.
That’s why roofing insulation is now considered best practice for building management. It reduces maintenance costs and ensures that the building and the roof are well protected against the Australian climate.
