Structural Insulated Panels Economic advantages across the project A shell constructed from SIPs is erected much faster and, therefore, more economically than a conventional shell. They enable builders to complete their part of the building project quickly and to provide a safe, weather-protected environment for other trades to carry out their work. And not being weather-dependent, the project is much easier to plan and complete, which also reduces cost and uncertainty. Unbeatable insulation values Insulation values for SIPs are vastly superior to conventional framing and insulating methods, as a building constructed with these panels is virtually airtight. Occupants have excellent control over the interior environment without the problem of draughts and irregularities in air temperature. To be precise: In a building constructed with SIPs there are none of the hot and cold spots found in homes built with conventional building materials. Precision and accuracy using CAD drafting systems The super-eco building benefits CAD drafting systems help to detail the SIP fabrication process, allowing precise cutting instructions to be sent to the SIP manufacturers (such as Hemsec) or engineers for foam, relief and spline set up. With the help of technological design systems the architect optimise the use of materials in all areas of the building. The ultimate environmentally- friendly product A key advantage of using SIPs in design is that there is no requirement for trusses in finished roof spaces. As an example, a SIPs building provides spacious room-in-roof attic rooms which increases total floor space by up to 25% in any project. Clearly, added floor space is desirable and adds to the value of the property. One of the major qualities of SIPs is that they are an environmentally-friendly resource. Their facings are made from renewable, farm-grown trees. This means that these components do not contribute to environmental degradation, making them an obvious choice for construction companies that care for the future of our planet. Planning a project with Hemsec SIPs in mind, before entering into the design phase, can lead to improved efficiencies during the process and eliminate unnecessary changes during later stages. 8 As well as reducing the cost to the occupant of heating fuels, a key advantage of using SIPs in the construction of homes is that they produce far less waste than buildings constructed from conventional materials as there is a reduction in harmful gases released from burning waste as well as a reduction in the need for landfill space. Excellent sound resistance As with timber studwork, acoustic performance using SIPs is determined by the mass and continuity of the plasterboard linings. Acoustic rated plasterboards are used to improve the insulation performance of walls where required.
