SIP panels

DESIP T&G panels


The use of SIP (Structural Insulated Panels) panels began in the 70s of the last century. This type of panel as such was invented in the 30s of the last century. The first SIP panel house was built in 1937, in the USA.


DESIP T&G consists of a timber frame filled with polystyrene foam sandwiched between OSB3 boards. OSB3 boards can be replaced with boards of other materials.


DESIP T&G panels are used in building construction:

  • floors;
  • walls.

DESIP T&G panels can be installed both on an existing structure frame and without it (the panels are self-bearing). No additional connections or parts are required for connecting the panels to each other.

Standard dimensions:

  • width 1250 mm;
  • length up to 6000 mm;
  • thickness 70 mm, 120 mm, 170 mm, 220 mm, 270 mm.


  • only DESIP T&G panels are available with the length of 6000 mm, thanks to the timber frame;
  • DESIP T&G panels are especially suitable for industrial buildings;
  • the assembly work productivity of the DESIP T&G panels is higher than in the traditional building;
  • DESIP T&G panels are easy assembling;
  • the average specific thermal conductivity of the DESIP T&G panels, also known as Lambda (λ), is 0,038; 0,036(W/mk);
  • the increased durability of the DESIP T&G panels is ensured by the fact that we use polyurethane adhesive in the production process, in order to achieve maximum firmness, and, in addition, we use nails for fastening all materials.
