Open cell foam

Insulating materials with various functions for different applications.

Polyurethane spray foams are one of the most versatile insulation materials used to address the needs of the construction industry. A significant advantage is the possibility of spraying it directly onto the surface to be insulated thanks to its high adhesion. An additional advantage is the rapid increase in volume, which means that it can adapt to the surrounding space, filling in any irregularities, gaps and empty volumes. Spray PUR foams are available in closed-cell and open-cell versions, each with its own advantages and limitations depending on the application requirements.

OPEN-CELL SPRAY FOAM SYSTEM

EMBEPUR® PRO100 FS

Polyurethane spray foams with an open-cell structure forms a soft, flexible and spongy insulation. The intracellular structure is characterised by 'broken' cell walls that allow them to be filled with air. They usually have a density of 8 to 12 kg/m3. This contributes to very good thermal insulation and air barrier properties. Open-cell foam is less resistant to mechanical damage due to its lower stiffness compared to closed-cell foams. An interesting aspect of polyurethane spray foams is the its over 100-fold volume expansion.

Advantages

  • Foam variant FS – Fire Stop – Increased flammability class E
  • Comparatively lower cost of materials – where economic efficiency is important, open cell foam is the first choice
  • It creates a noise barrier in the typical frequency range
  • Flexibility – open-cell foam is more flexible, so it can adapt to the expansion and contraction of the frame elements under the influence of weather
  • Water vapour permeability – in situations where moisture passes through the insulation, such as in roofs, leaks from the roof enter the attic space below, where it is more likely to be detected
  • Flammability class E

EMBEPUR® PRO100

Advantages

  • Comparatively lower cost per material - where economic efficiency is important, open cell foam is the first choice
  • Provides a sound barrier in the range of typical frequencies
  • Flexibility - foam with open cells is more flexible, enabling it to adapt to the expansion and contraction of the frame parts under the influence of atmospheric conditions
  • Water vapor permeability - in situations where moisture passes through the insulation, such as in roofs, it will allow leakage from the roof to enter the space below where it is more likely to be detected
  • Fire class F
  • 25 years guarantee for the insulation

Benefits (over alternative insulation materials)

  • Despite the requirements related to professional application (spraying) using high-pressure equipment, the application process itself is much simpler
  • More effective, durable and lighter insulation improves the condition of the building without unnecessarily burdening the structure
  • More effective maintenance of the expected temperature inside thanks to the elimination of heat losses (thermal bridges)
  • Better air-sealing thanks to the initial liquid form, and more than 100-fold increase in its volume
  • Material efficiency – insulation applied directly to the surface without the need to use primers to improve adhesion, strings or adhesives for insulation materials

WHAT WE OFFER

Whether in residential, commercial or industrial construction, the insulation of ceilings, attics and walls requires considered choice in the selection of the insulation materials. See for yourself where our spray polyurethane foams work best.

Attics

Attics

Polyurethane spray insulation enables the sufficient and complete insulation of attic spaces, a source of about a 25% of the energy losses for heating or cooling, allowing you to effectively save money by reducing your operating costs, while also protecting the natural environment. Thanks to this we achieve triple protection against: cold, draughts and noise.
Ceilings

Ceilings

Thanks to the insulation of ceilings with polyurethane spray foam, the loss of heat from the rooms is effectively limited, allowing thermal comfort to be maintained. In addition, as the ceiling does not cool, moisture does not condense on it. This helps protect interiors against the potential for microbiological hazards. Due to the universality of spray polyurethane foams, the required thickness of the insulation layer depends on the temperature in the room.
Walls

Walls

Insulating the walls on the inside is often the only possible way to improve the thermal insulation of a building. In such a situation, spray PUR foams can be one of the fastest and most effective solutions, mainly by minimising the relatively high risk of moisture formation inside the partitioning and hence avoiding the appearance of mould on the walls. Foam sprays are also used as a system of acoustic insulation for internal walls.
