A structural insulated panel, or structural insulating panel, (SIP), is a form of sandwich panel used as a building material in the construction industry. SIP is a sandwich structured composite , consisting of an insulating layer of rigid core sandwiched between two layers of structural board.
Founded in the 1960s by Eugene Murtagh, the company floated on the Irish Stock Exchange in 1989 with a value of IR£20m. [4] It expanded into insulated panels and rigid insulation boards via numerous greenfield plants and acquisitions, including the European insulation arm of CRH plc in 2010 [5] and the construction division of ThyssenKrupp Steel in 2012.

In 2001 Kingspan Off-Site purchased a German-based business, TEK Haus, which manufactured a Structural Insulated Panel Building System (SIPs). [2] Incorporating SIPs technology, the Kingspan TEK Building System was launched in 2001. Kingspan Off-Site then acquired Century Homes, set up by the McCaughey brothers in Monaghan, in 2005. [2]
Sandwich panels are used in applications where a combination of high structural rigidity and low weight is required. The structural functionality of a sandwich panel is similar to the classic I-beam , where two face sheets primarily resist the in-plane and lateral bending loads (similar to flanges of an I- beam), while the core material mainly ...
LVL is a type of structural composite lumber, comparable to glued laminated timber (glulam) but with a higher allowable stress. [1] A high performance more sustainable alternative to lumber, Laminated Veneer Lumber (LVL) beams, headers and columns are used in structural applications to carry heavy loads with minimum weight.
Panel buildings may refer to buildings of one of the following types: Built of structural insulated panels; Built of pre-fabricated concrete blocks, named differently in various countries. Large Panel System building known as Plattenbau in German, Panelák in Czech and Slovak, wielka płyta in Polish and Panelház in Hungarian.
An Iowa panel is recommending eliminating or consolidating more than 100 state boards and commissions to shrink state government. A state panel wants to eliminate 100-plus Iowa boards and commissions.
Some manufacturers still use Hydrochlorofluorocarbons (HCFCs) which are still harmful to the ozone layer, but not to the same extent as CFCs. As the blowing agent leaks, air replaces the insulating gas, and the R-value of the panel drops. Most rigid panels are made from crude oil byproducts, and some toxic pollution results during their ...
