Insulation with the highest quality parameters - BauderPIR panels

08 of March '21

Bauder thermal insulation boards.
From the series "Roofing - trends 2021".

Bauder is one of the largest manufacturers of rigid polyurethane foam panels, an insulator with extraordinary quality characteristics. At a time of ever-increasing requirements for thermal insulation due to environmental concerns and the validity of energy-saving guidelines, the product sold under the BauderPIR brand has become an indispensable material.

The main advantages of BauderPIR thermal insulation boards are:

  • High thermal insulation performance
  • Stability and compressive strength of BauderPIR
  • Thermal resistance
  • Chemical and biological resistance
  • Fire resistance of PIR foam on lightweight steel structures

In order to provide optimal solutions for different types of flat roofs, it is necessary to use different boards. For industrial roofs, a possibly lightweight large-format board is very suitable, while for roofs with smaller areas to be covered with weldable membranes, boards of other formats are necessary.

BauderPIR FA - a "slim" board for thermal insulation of flat roofs

It was designed specifically for thermal insulation of light industrial roofs. Thanks to the good insulating properties of polyurethane, it is possible to significantly reduce the thickness of the insulation layer. Combined with the low density, we get a lightweight structure formed by large-format panels.

One panel covers an area of 3 m² of the roof surface at a weight of only 9 kg (for a thickness of 100 mm). Due to the very high strength of BauderPIR FA panels, it is not necessary to mark out separate paths for foot traffic as in the case of other materials. There is also no risk of damage to the waterproofing through protrusion of the rigid connector and through soft substrate.

BauderPIR FA roof insulation board is characterized by the lowest thermal conductivity. The heat transfer coefficient ("U") at 12 centimeter thickness of the board is 0.18 W/m²K. In order to achieve the same U-value as with a traditional thermal insulation material with a λ of 0.040, the thickness of BauderPIR FA board can be reduced by 100 mm.

BauderPIR M/MF - a handy board for thermal insulation

Particularly recommended for installation together with quick-weld bitumen membranes. Thanks to the mineral fleece coating, the surface of the board can be exposed to open flames for short periods. Welding with the substrate, on the other hand, can be done through THERM strips located on the surface of BauderTHERM DS1 DUO or BauderTHERM DS2 quick-weld vapor barrier membranes.

Due to the mineral fleece coating, a thermal conductivity coefficient of 0.027 W/(m-K) applies for board thicknesses up to 80 mm. For greater thicknesses, the value is 0.026 W/(m-K), and from a thickness of 120 mm - 0.025 W/(m-K). Boards from 40 mm upwards can be produced with a staggered overlap. From a thickness of 120 mm onward, the boards are equipped with a milling cutter as standard.

BauderPIR T with a molded slope. Planning the slope through thermal insulation panels

Any type of roof, whether it is a solid reinforced concrete structure or a lightweight construction on trapezoidal sheet, is subject to deflection due to its own weight and imposed load. Roof drains are usually placed at the junctions of the structural elements, so they are located in the deepest places. Water, on the other hand, accumulates in places of deflection and forms stagnation there. The waterproofing is then stressed both by temperature faults between the edge of the stagnation and the roofing felt, as well as by the frequent accumulation of dirt at the site of such depressions.

BauderPIR KOMPAKT. Special board for thermal insulation of compact roofs

BauderPIR Kompaktdach is a flat roof system in which the waterproofing and thermal insulation are attached to each other with the entire surface without air voids., o excludes the penetration of water under the covering in the event of possible damage to the roof. The effects of mechanical damage to the covering remain at the site of their occurrence and do not spread to others. Direct and complete bonding of insulation layers to the substrate in the event of damage prevents the spread of damage. Defective areas can be precisely located.

BauderPIR FA TE. Thermal insulation boards for terraces and balconies

When you want to insulate the spaces under terraces, you need optimal and guideline-compliant thermal insulation to do so. In doing so, BauderPIR panels provide the best possible insulation performance. In addition, they are free of thermal bridges and do not shrink.

BauderPIR FA drop panels. Aluminum-coated drop insulation

BauderPIR FA drop panels are a high-quality, standard drop insulation consisting of aluminum-coated drop panels with a thermal conductivity coefficient of λ 0.022. The associated valley or ridge fillers (BauderPIR KFS or BauderPIR GFS) simplify installation in the valley and ridge area on the one hand, and essentially reduce material losses on the other.

The new BauderPIR FA sloped 2.0% thermal insulation panels make it possible, with a small number of standard components, to easily realize 2% slope thermal insulation with different lengths and characteristics. Installation can take place on any supporting structure on a suitable Bauder bitumen vapor barrier. Depending on demand, the installation is carried out on flat BauderPIR FA panels. In the next step, the new thermal insulation BauderPIR FA sloping boards are laid based on the slope plan. Helpful for the installation is the anti-glare surface, a grid for easy cutting, as well as marking the slabs and printing with the direction of the slope.

BauderECO F - components

Insulation core

The insulation core consists largely of biomass (agricultural waste such as plant stalks and leaves, threshed corn cobs) and recycled materials (sawing and milling waste from the production of our thermal insulation materials). Together, this results in high insulation (λ 0.023/0.024) with low energy and raw material consumption. The element with the smallest thickness meets the highest thermal insulation requirements. Additional advantages are low weight and high compressive strength.

Covering layer

The double-sided, breathable covering layer is made of shell lime and glass fleece. Shell lime is a waste product in the food industry.

Milling around the plate

Milling around the slab ensures that there are no thermal bridges. This also applies to single-layer systems.
