Insulation protects the home’s building envelope from the elements, but it can also be a barrier to air infiltration. This air infiltration expedites heat transfer between indoor and outdoor temperatures, reducing insulation R-values. This can also increase energy costs and make occupants uncomfortable.Source:https://straightedgeinsulation.com/
To keep the R-value of a particular type of insulation at its maximum, it is important to install it correctly. While many types of insulation can be installed by homeowners, others require professional installation. Obtain written cost estimates from several contractors for the R-value you need and pay attention to the installers’ experience.
How Straight Edge Insulation Enhances Indoor Air Quality and Comfort
One of the most overlooked construction details for insulating homes is slab-on-grade perimeter insulation, often referred to as “slab-edge” insulation. While this simple and inexpensive detail can dramatically improve a home’s thermal performance and occupant comfort, it is frequently installed incorrectly.
When installed properly, the R-value of slab-edge insulation is about equal to that of foam board insulation in other parts of a home’s wall assembly. It also offers the advantage of eliminating other weatherization steps like caulking and installing a house wrap or vapor barrier.
These straight edges, manufactured by Preisser, are ground flat to within 0.001 inch (0.025 mm) over the entire length on both sides and stress-relieved to remain true under temperature variation. They are 1-1/2″ wide and have a cut-out hole at one end to hang for storage. The cladding on these straight edges is black melamine with a smooth outside layer. It is bonded to the core with an industrial grade epoxy.
