Rigid foam board insulation, also known as “pink board”, is a flat insulation used for various insulation work. It is easy to install, less itchy than fiberglass insulation, and provides heat retention, soundproofing, and a smooth surface for trim and bricks. It is commonly used in residences and can be placed on the exterior walls to block wind and drafts.
Rigid foam board insulation, or “pink board” as it is commonly called, is a hard, flat insulation that is used for many types of insulation work. The large square slabs are drilled to different sizes to allow the boards to be cut and inserted between the wall studs. They are available in a variety of thicknesses to provide a wide range of R-value insulating properties. While not as well known as fiberglass roll insulation, rigid insulation pieces are much less itchy and easier to use in comparison .
When it comes to placing insulation within a wall, covering the space is a quick process with rigid foam board insulation. Large papers break easily into smaller sized pieces by snapping the perforated line onto a sawhorse or corner post. Once the large sheet has been broken down to the correct size, it simply sits between the wall studs and is held in place with a piece of masking tape. Pink plank can also be used on interior ceilings.
One area where this insulation outperforms its fiberglass counterpart is the residence of a building. Often, when you reside, a contractor chooses to place rigid foam board on the walls before hanging new siding. This insulating layer on the outside of the structure adds many times to the insulating factor of the building. By placing rigid foam insulation board against the exterior walls, wind and drafts are blocked before they can enter the walls. This creates a much hotter building in the winter and a cooler building in the summer.
Placing the pink board on the outside of the structure also provides a smooth, level surface on which to hang the new trim. This method of supporting the fitting also provides a firm, but giving, cushion to the fitting and can prevent breaking or bending when struck with a hard ball or similar object. A notable side benefit of installing this type of insulation is noise reduction. The plank provides a layer of sound insulation which often creates a more comfortable and quiet habitat.
Ease of installation, heat retention, and soundproofing are three reasons why many contractors and builders choose rigid foam board insulation when finishing new construction or renovating an older building. The pink board also creates a solid, level surface on which to lay facing bricks and blocks. Adding insulating properties to a brick wall is a typical use of insulation.
