Structural insulated panels or SIPs used in constructing homes and buildings are continuously gaining attention because of the many benefits of these engineered panels. SIPs are pre-fabricated in off-site facilities and delivered ready for installation. Although conventional building materials are still more popular than SIPs, the increase in attention and adoption is a clear testament that there is a promising future for SIP panel homes as an advanced technique in construction.
SIPs reinforce faster construction and impressive results
Replacing traditional wood frames with SIPs eliminates many of the structural vulnerabilities inherent in such conventional methods. For example, traditional wood frame walls require adding insulation manually; whereas SIPs already have a built-in insulation core. Builders who use SIPs agree that SIP homes have better workmanship and construction quality.
Apart from superior quality, using SIPs also leads to faster construction time. There is no need to hire separate staff for installing insulation and equipment such as cranes may be used to assist in erecting the panels.
Superior thermal performance
The R-value or thermal performance of SIPs is significantly higher than conventional wood frames. The thermal performance of a building envelope refers to its capability to prevent air infiltration. The less air that enters in building joints and seams, the better the capacity of the building to retain warm air and cold air longer. A well-insulated home is also more energy-efficient because there is less dependence on artificial heating and cooling.
Improved load bearing capacity and overall durability
A SIP panel structure is stronger than a conventional wood frame. The foam insulation core adds rigidity to the boards which adds to the total load-bearing capacity of the panels. SIP panel construction results in a building that is not only impact resistant, but also highly tensile and robust.
Protection from insect infestation and mould growth
SIPs are not by nature, insect or mould repellent. However, manufacturers can take specific measures to treat the boards to protect against termite and insect infestation as well as mould growth. As such, it is essential to consult with the manufacturer in terms of options available to treat the material before installation.
Comparable in cost to conventional building methods
Some would argue that SIPs are expensive. But if you consider the amount you save in labour and construction time, the savings are more than enough to compensate for the relatively higher cost of SIPs.
Environment-friendly building material
Conservation of natural resources is another principle that governs most modern building methods today. SIPs manufactured in factories minimise waste and promote recycling. Apart from this, SIP homes and buildings have superior insulation which increases energy efficiency. SIPs also help reduce the need to use non-renewable construction materials such as concrete.
In conclusion, using SIPs to build homes and other structures promotes green-building techniques and reinforces structural stability, durability, and insulation. Although far from mainstream adoption, architects and builders around the world are slowly paying attention to the many benefits of using SIPs instead of conventional framing methods.
