Cost comparisons have shown that building with SIPs is no more expensive than traditional building techniques when the following factors are taken into consideration:
Reduced cost of land
A SIPs roof structure does not require roof trusses and will provide an open habitable warm room in the roof, allowing a three bedroom house to be turned into a five bedroom house on the same size plot.
Reduced cost of foundations
A SIPs structure is a lightweight shell and therefore does not require a heavy foundation design.
Reduced cost of losses through damage or theft
The elements which make up a SIPs structure are generally very large and robust and are therefore inherently unlikely to be damaged or stolen from site. A significant percentage of traditional building materials are either lost, damaged or stolen from sites. The speed of build and the nature of SIPs virtually eliminates this wastage.
Reduced cost of labour - A SIPs structure simplifies the process of construction and can reduce construction time by up to 60%. Once the foundations have been completed, our team can arrive on site with a pre-engineered structure and within 2 to 4 weeks will have erected a weather tight structural shell ready for windows, doors, services and internal and external finishes. The nature of SIPs provides a square, smooth structure which helps follow-on trades and so reduces the eventual cost of snagging.
Reduced cost of waste disposal
A SIPs structure is pre-engineered off-site to avoid both the additional labour and the ever increasing cost of the safe disposal of waste materials.
Reduced site costs
A faster build programme will reduce the overall cost of project management, and in turn will also reduce the cost of hiring scaffolding, plant, safety and security equipment and temporary accommodation.
Reduced heating costs
The unbeatable insulating qualities of SIPs allow a much smaller heating system, combined with a mechanical ventilation system to be installed. This will permanently reduce heating bills by up to 60% over the lifetime of the building when compared with traditional methods of construction.
Quicker return on investment
Building a SIPs structure can radically increase the speed of construction, providing a quicker return on investment. This allows the capital to be used on the next project when it would otherwise still be tied up on a traditional build. A significant gain can be made over a period of time maximizing the return on the initial investment and maintaining a positive cash flow.
Better Resale Value
SIPs houses are attractive to future buyers and occupiers, due to the reduced running costs and the many other benefits that a SIP house provides.
