Lambdaboard® insulation comprises the highest R-value per thickness, together with excellent fire resistance, making it ideal for reducing energy use in buildings.

“Climate change is a reality. As an industry, and as responsible members of society, we need to work to reduce emissions,” says Rigifoam’s Duncan Goldsmith.

From a commercial building perspective, when businesses are able to cut the amount of energy used to heat or cool a facility, the result is a reduction of greenhouse gas emissions and energy use, which translates to cost savings.

Focus on the building envelope
“In the past, the building community thought about the efficiency and effectiveness of individual building components,” Goldsmith explains. “Times have changed. Now the built environment is taking a more holistic view by looking at the efficiency of the entire building envelope. From new construction to retrofits, we’ve realised we can create more energy-efficient buildings from the ground up.”

According to Goldsmith, the focus needs to be on how all the components of the building work together. The design and condition of the building envelope, the quality of materials, workmanship and transitions from one system to the next: Foundation to walls, walls to doors, walls to windows, and walls to roofs, are all critical in creating a tight, efficient building envelope. In order to have an efficient building envelope, a commercial building needs to control heat, air, and moisture vapour and moisture water.

Changes to building codes
The necessity for high-performance building envelopes to decrease energy use has caused the International Code Council (ICC) to create and mandate codes to incorporate air barrier requirements. Societies like ASHRAE are in place to advise and make recommendations to the ICC that advance the heating, ventilation, air-conditioning and refrigeration of buildings.

These changes to codes over time have increased the minimum required R-values.

Lambdaboard® responds to high requirements
Lambdaboard® is a polyisocyanurate (PIR) insulation, one of the materials with the most robust R-value performance, that runs continuously across structural members without thermal bridging and/or compression.

The effectiveness of PIR is backed globally by rigorous testing, which has proven it to be not only a superior insulation material, but its fire resistance qualities also make it a superior choice for building.

Benefits of PIR:
•    Highest R-value per thickness.
•    Meets new insulation standards.
•    Moisture resistance.
•    Low environmental impact.
•    Zero ozone depletion potential.
•    Recyclable.
•    Cost-effective, optimised.
•    Long service life.
•    Thinner walls and roofs with shorter fasteners.
•    Extensive building code approvals.
•    Preferred insurance ratings.
•    Dimensional stability.
•    High compressive strength.

Superior fire test performance:
•    PIR will not melt or drip when exposed to fire.
•    PIR forms a char layer, creating resistance to flames.
•    PIR foam will not spread flames.
