Insulation for Pitched Roofs

Insulation for Pitched Roof
Insulation of pitched roofs is challenging.

Considering today's scarcity of residential accommodation and bearing in mind the ever-increasing cost of energy, no property owner or developer can afford to do without thermal insulation for pitched roofs. This holds true for new buildings as well as for old ones requiring modernization.

Pitched roofs present special problems, e.g. openings for chimneys can prove to be weak spots through which moisture can enter. Because of their accurate fit, Covestro's insulating panels and systems made of rigid polyurethane foam provide outstandingly consistent insulation without thermal bridges. There are various insulating options: systems for insulating on top of the rafters are often used when working with conventional rafter constructions and new buildings. This is the best and most efficient method of insulating a roof, because the insulating material completely envelops the roof, thus protecting the whole roof structure against adverse temperature influences.

When carrying out attic conversions, the insulating material is often applied beneath the rafters in order to reduce the loss of energy through the roof. Here, the polyurethane insulating panels made from Covestro raw materials demonstrate their superiority over other insulating materials because the loss of usable space is small owing to the panels' minimal thickness.

Advantages of polyurethane insulating panels for pitched roofs:

  • Space-saving
  • Dimensionally stable
  • Exclusion of soot, dust, wind and rain
  • Long service life
  • Suitable for fitting around roof openings (chimneys, aerials, etc.)
  • Light weight
  • Special joint design
  • Decorative interior design
  • Good resistance to chemicals and wood preservatives

Covestro also offers its customers the opportunity to eliminate expensive rafter construction altogether by using special self-supporting polyurethane wood sandwich panels. The panels are directly mounted onto the horizontal purlins, thus forming a perfect seal on the inside of the roof.
