SIPS EXPLAINED

 

Structural Insulated Panels (SIPS) are an advanced method of construction offering excellent thermal performance, light-weight structural strength and time and cost saving benefits over traditional construction methods or systems. SIP panels are used in floors, walls and roofs for residential, commercial and educational applications, providing ecologically friendly and energy efficient buildings.

SIP MAJOR BENEFITS

EXCELLENT THERMAL PERFORMANCE

Structural Insulated Panels provide superior thermal performance, which will last the life span of the building. This is due to the solid core of polyurethane (PUR) insulation throughout the structure which ensures that the building is heated evenly, remains free from cold spots and will benefit from reduced heating costs.

LOW U-VALUE WALLS AND ROOF

Structural Insulated Panels offer extremely high thermal performance, the Polyurethane (PUR) core of rigid insulation and OSB/3 archives U-VALUES as low as 0.10 Watts per Metered Squared Kelvin (W/m2K) or better, making significant savings on your annual heating costs.

INTEGRAL INSULATION

The insulation is integral to the SIP Building System, and therefore eliminates the need and cost for cavity insulation.

HABITABLE ROOF SPACE

SIP Building Systems do not require roof trusses, therefore providing an additional habitable room in the roof.

EXTRA FLOOR SPACE

Structural Insulated Panels create more internal floor space for the same external dimensions in comparison to masonry construction. This is because a SIP structure provides excellent strength and insulation in a smaller wall section.

ENVIRONMENTAL SUSTAINABILITY

A SIP home is environmentally friendly for several reasons. Structural Insulated Panels are made from timber which is sourced from managed plantations. Timber is seen as a green building material because trees produce oxygen and remove carbon dioxide from our atmosphere and timber is the only truly renewable building material.

The polyurethane (PUR) core of insulation in the Structural Insulated Panels is CFC/HCFC-free with zero Ozone Depletion Potential and a Low Global Warming Potential (GWP).

LOW WASTAGE

Structural Insulated Panels are pre-engineered in a factory which results in less defects and wastage throughout the manufacturing and construction processes.

FAST CONSTRUCTION METHOD

By using Structural Insulated Panels, on-site construction time can typically be reduced by up to sixty percent (60%).

IMPROVED SCHEDULING & PROGRAMME CONTROL

External and internal follow on trades can start sooner as the SIP Building System, when wrapped with a breather membrane, offers a weather-tight shell helping you complete your project faster.

With a SIP Building System it is easier to predict project completion times as the system is relatively simple to erect and requires no wet trades or brick layers.

ROBUST AND SOLID FEEL

A SIP home delivers a robust and solid feel compared to other timber frame systems. This is achieved due to its solid core construction and the fixing of plasterboard directly to the inner face of the SIP Panel.

AIR-TIGHTNESS

Poor air-tightness is a major cause of heat loss. A SIP home provides a controllable indoor environment due to the superior air tightness of the system. This enhanced with the use of a Mechanical Ventilation with Heat Recovery (MVHR) system or similar.

LIMITED COLD BRIDGING

Structural Insulated Panels are joined together with an insulated SIP spline providing a continuous polyurethane (PUR) core through the walls and roof of the building. This greatly improves the thermal efficiency of the building compared to timber frame studs and cavity insulation which is prone to slumping and mortar drops during the construction process.

SOLID PANELS PROVIDE A RIGID SURFACE FOR FIXINGS

In most cases, no additional timber ’noggins’ are required to facilitate the hanging of radiators and kitchen units as is required with timber frame construction.

EXCELLENT RESALE POTENTIAL

SIP homes are attractive to future buyers and occupiers due to the inexpensive running costs of a SIP structure and the many other benefits a SIP home provides.

THE CODE FOR SUSTAINABLE HOMES

Structural Insulated Panels contribute to The Code for Sustainable Homes through excellent thermal performance, air tightness and limited cold bridging.

About the Code for Sustainable Homes
The UK Government introduced the Code as a voluntary standard in 2007, complementing the current system of Energy Performance Certificates for new homes. From September 2010 all new build dwellings, both public and private sector are obliged to comply with the Code.
