Structurally insulated roof panels (SIRPs) can streamline any roofing project. They’re easy to handle and install, which can improve the efficiency of a project while significantly reducing building time. Not to mention, they’re energy efficient and require less manpower to install. SIRPs are composed of two layers of metal or wood sandwiching Polyurathane insulation, which makes them highly insulating, thus beneficial to homeowners. Without proper guidance, however, homeowners and builders sometimes fail to choose the right panels for their project. Make note of the common pitfalls below, and consult with our knowledgeable team at Advanced Panel before purchasing your panels.
Not Accounting for Possible Contraction or Expansion
Because of how they’re constructed, SIRPs are more vulnerable to contraction and/or expansion than other building materials. Before choosing the insulated panels and creating a roof design, the potential for movement should be considered. If it isn’t, the roofing system could fail. Let this possible contraction and/or expansion be a guide for the size the panels should be, as well as how their joints should be positioned, and talk to our team for assistance.
Choosing Incompatible Fasteners
All SIRPs must be placed with fasteners. Incompatible fasteners can cause issues for the roof panels. For example, if the fasteners are made of a different metal than the steel roof panels, there might be a reaction between the two. Additionally, ill-sized fasteners can cause panels to loosen and separate, so purchasing the correct fasteners is just as important as purchasing the correct panels.
Purchasing the Wrong Colour
Believe it or not, the colour of SIRPs matters way beyond style. For example, a colour that absorbs heat can cause the outer layer of a panel to overheat and place stress on the rest of the panel. This can lead to corrosive damage throughout the roofing system. The exterior of the panels should always reflect light, so light-coloured panels are first choice. Just remember to specify your colour choice or you might receive a 'standard' colour.
Buying Panels with the Wrong R-Value
SIRPs can be air tight, but only if the R-value is correct. If you’re not an expert, it may be impossible to choose panels with the ideal R-value. The higher the value, however, the more efficient the panels. Panels with higher values will provide better insulation and a greater thermal barrier between the roof and the home. To determine the best R-value for their SIRPs, buyers should always consult with a manufacturer, like one of the knowledgeable people at Advanced Panel Products.
