You won\u2019t have to do any measuring with spray foam and it will naturally pour into cracks and seal everything so there are no leaks and gaps.  <\/p>\n<p>With rigid foam insulation you may have to rip out existing insulation and measure out the material to ensure it covers everything. Rigid foam isn\u2019t going to expand leaving more potential for draughts.<\/p>\n<p><strong>Which is more efficient? <\/strong><br \/>\nBoth have similarly high R values and in theory there may be no difference in the level of insulation. However, if there are any gaps left while installing it can dramatically reduce the thermal efficiency and this is more likely with rigid foam insulation.  <\/p>\n<p><strong>Which is cheaper? <\/strong><br \/>\nIf we take rigid foam and spray foam in isolation the former is likely to be cheaper but what this doesn\u2019t consider is the extra work that may be required to install it. Using spray foam is a lot faster and will involve less disruption. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Spray foam and rigid foam both have their advantages and disadvantages depending on the insulating project.
