Lambdaboard®

SUPERIOR

INSULATION

Finally an insulation material that offers you LTTR (Long Term Thermal Resistance) on top of that a life time guarantee on the R-Value.

LAMBDABOARD is a flexible faced Polyisocyanurate (PIR) insulation board, manufactured on a continuous laminator In South Africa. That offers you the best possible insulation values available in the market. LAMBDABOARD is the perfect solution for ceilings, doing away with the outdated method of ceiling and insulation practices, no more pest and rodents nesting in your ceiling insulation.

LAMBDABOARD versatility allows the board to be used in an array of applications, from ceiling, cavity walls, underfloor heating too slab insulation.

Using LAMBDABOARD will save you time and money, by reducing your energy bill and installation costs. PROVEN.

Take control of your energy costs

Using Lambdaboard has been proven to reduce your energy consumption. The investment in Lambdaboard will repays it self in 2-4 years.

In a bid to remain faithful to its mantra, "Take control of your energy costs", Rigifoam recently renewed its commitment to the supply of insulation capable of reducing operational heating and cooling costs resulting in positive environmental and climate change consequences. Its launch product, LAMBDABOARD, is a unique solution to the current energy crisis.

R-VALUE PERFORMANCE

LAMBDABOARD has the highest R-value per 25mm thickness, therefore the design U-value of the insulation system can be achieved with a minimum thickness. This in turn allows the overall footprint of the building to decrease and reduces the cost of construction.

Installing Lambdaboard will have positive impact on the HAVC system required, reducing the requirements for over engineered systems, thus having an effect on energy consumption required to run the HAVC system. Putting money back in your pocket.

40mm (1.67) 50mm 60mm 65mm
50mm (2.08) 70mm (30mm + 40mm boards) 80mm 80mm
60mm (2.50) 80mm 100mm 100mm
70mm (2.92) 90mm (40mm + 50mm boards) 120mm 120mm
80mm (3.33) 100mm (50mm + 50mm boards) 130mm 135mm
90mm (3.75) 110mm (80mm + 30mm boards) 150mm Cannot compete
100mm (4.17) 125mm (60mm + 65mm boards) 170mm (80mm + 90mm boards) Cannot compete

* when using a double layer board, fire compliance is comprised, the labour costs to install the boards are also doubled. *

The regulations were designed to counter act the dramatic climate change and the degradation of the planet. The South African Government promulgated the SANS 10400 XA building codes, in order to reduce greenhouse emissions These regulations are designed to reduce energy usage and pollution in the built environment.

Lambdaboard has a proven R-Value and a Long-Term Thermal Resistance (LTTR) and will outlive the life span of the building, reducing the future building envelope’s energy consumption and demand, compared to similar thermoplastic products in the market.

Lambdaboard is a member of PIMA (Polyisocyanurate Manufactures Association) with has a proven track record in LTTR and sustainability.

Lambdaboard provides 30% saving energy consumption. 70% of heat loss can be found in the roof of a structure. Lambdaboard can reduce this by 100% so that no heat is lost via the roof structure.
