What is the difference between a three and a four-season enclosure?
A4: Typically, a three season room has a 2″ or 3″ wall thickness with a 3″ or 4″ roof thickness. Glass windows are typically single-pane and walls are not thermally broken. A four-season room will usually have thermal breaks throughout along with insulated glass. Wall thickness is usually a minimum of 3″. Branstrator Incorporated offers both three and four season rooms along with a host of options including wallpaper interiors; Low-E/argon filled glass and welded frame vinyl window sashes.
