A process and system for making a laminated surface covering and the surface covering itself are described. The covering includes several layers bonded to each other. The system performs the process. One example of the process includes passing a first material across a first conveyor, passing a second material across a second conveyor, passing a bonding material across a third conveyor, contacting the first material and the second material to the bonding material, and heating at least one of the first material and the second material. The process also includes introducing the first material, the second material, and the bonding material into a pressure zone such that the bonding material is introduced between a bottom surface of the first material and a top surface of the second material. The process applies pressure to bond the first material and second material together via the bonding material to produce a laminated material.

The insulation tile comprises a first planar surface, a second planar surface and side surfaces defining the surfaces, and a casting compound layer as well as an insulation material layer, which is manufactured from thermal insulation material, the compression strength of which is at least 10 kPa. The casting compound layer forms the first planar surface of the insulation tile and the insulation material layer forms the second planar surface of the insulation tile. Furthermore, the insulation material layer of the insulation tile comprises grooves in the area of the planar surface which will be against the casting compound layer. The insulation tile according to the invention can be used in floor, roof and wall structures.

A polymer composition comprising a first poly(vinyl butyral) resin having a first residual hydroxyl content; a second poly(vinyl butyral) resin having a second residual hydroxyl content; a plasticizer; and at least one compatibilizer, such as an anhydride compatibilizer; wherein the difference between the first and second residual hydroxyl contents is at least 2 wt. %, and wherein the polymer composition has a percent haze of less than 5%. The use of a compatibilizer reduces or minimizes the optical defects, such as haze and color, without sacrificing other characteristics of the composition. The composition may be used in an interlayer.
