Straight Edge Insulation

Straight Edge Insulation (or slab-edge insulation) is one of the most important, yet frequently abused construction details. It offers enormous energy savings and occupant comfort gains when done correctly. Unfortunately, many builders scrimp on this crucial component of a cost-effective and durable home.

Traditionally, builders have used fiberglass batts or rolls for this type of insulation. But, recently, more and more builders have opted for foam-in-place insulation products, such as closed-cell or open-cell polyurethane. Foam insulation can reduce the cost of weatherization by eliminating the need to apply a housewrap and vapor barrier, and by providing an air, moisture, and thermal barrier in a single product.

Soundproofing Solutions Made Simple with Straight Edge Insulation

Foam-in-place insulation can be installed by the homeowner, or a contractor, in most residential situations. The installer needs to follow the manufacturer’s instructions for installation and use of the product. Foam insulation is available in a wide range of R-values, and the installer should consult with the product manufacturer to determine what R-value is appropriate for the climate zone and the application.

To ensure that the insulation is placed properly, a straight edge should be used to mark the location of the first course. The straight edges that Preisser makes are calibrated to meet the DIN 874 GG-00 standard, which works out to about 3/1000 of a millimeter. These straight edges are manufactured from a tough, hardened steel alloy and burnished to be glare-free. They come with a plastic tip protector and are encased in a vinyl case.
