Invisible but everywhere

• Our PU foams seal gaps, cracks and thermally insulate joints, thus preventing energy losses in buildings and reducing their CO₂ emissions.
• Penosil PU foams save over 70 times more energy during their lifecycle than was needed for their manufacturing process.
• 1kg of PU foam saves 1,000kg of CO₂ during its lifecycle. By comparison, a tree can absorb around 1,000kg of CO₂ over its 100–year lifetime.
• PU foam is an excellent insulation material as it can access otherwise hard–to–reach places, and it has a lower thermal conductivity than mineral wool.
• Correctly applied PU foam also acts as sound insulation and reduces the risk of condensation and mould.

• Buildings’ airtightness helps to prevent air leakages, humidity problems and condensation, increases fire safety and minimises noise problems.
• The air leakages account for about 25% to 40% of heat losses in a cold climate and 10% to 15% of heat gain in a hot climate.
• Even the smallest unsealed crack in the structure can have a big impact on a building’s energy efficiency.
  For example, a 1mm-wide unsealed joint in an exterior wall in wintertime can increase the wall’s heat loss by around 4.8 times more than a sealed joint.
• To improve a building’s airtightness, it is crucial to use sealants to seal even the smallest crack in the structure.

The typical places for air leaks are:

Doors 10%

Windows 15%

Roof construction 25%

Penetrations through building’s envelope 15%

Building’s envelope 35%

• Wrongly installed windows and doors can cause a lot of heat loss in a building.
• Penosil offers various energy-efficient building solutions for window installations and facade sealing.
• If used together and in the correct order, the products in Penosil’s Energy Efficient Window Installation solution help to minimise a structure’s thermal bridges and its CO₂ emissions.
