Wood moves. Temperature fluctuations and moisture lead to constant change. And Ramsauer’s sealants are fully equipped to keep up with it.

A natural attachment to wood

Timber has been a key part of creating living spaces for millennia. It’s a material that breathes and responds to its environment. Inhospitable weather and swings in temperature can affect its composition. It requires sealants that will adjust to this transformation while also being able to provide a lasting bond.

Decades of experience for the best window putty

We have decades of experience with window putty, so we know all about it and what it requires. Sealants used to assemble timber windows must meet the highest standards and demonstrate specific qualities. Moisture can lead to mould forming, for instance, and sun rays could create porous spots. The sealant also needs to be capable of withstanding mechanical forces and abrasion. When the right material is deftly applied, the result will be an attractive and functional seal that’s made to last. 

  • The sealants should be compatible with laminated glass.
  • The material should be easy to shape and smooth.
  • We recommend non-corrosive sealants.
  • The material should attach without priming.

No gaps for draughts

Interior joints in a home connect doors and windows to the masonry. As well as bonding these elements to the wall and holding them in place, these joints also prevent draughts from blowing in and mould from forming when properly executed. That’s why it’s particularly important to seal these points so that they are air-tight with a thick enough joint. Professional installation will deliver seamless joints that work as intended.

  • Low emitting materials are best suited for indoor use.
  • The sealant needs to be compatible with the relevant coating system.
  • A brush-on material will ensure an attractive outcome.

Weather-proof seals

Professionally executed perimeter joints on windows and doors are more than just essential for a properly sealed building envelope and a warm home. An imperfectly jointed structure can also result in considerable damage to the masonry. It’s imperative that joints between doors and windows are fully sealed from driving rain on the outside. At the same time, the sealant should be less impermeable to vapour than that used in interior perimeter joints. Different skilled-trade professions are responsible for this task based on how the sealant is to be applied.

  • Construction materials resistant to weathering and ageing allow joints to stay sealed long-term.
  • An elastic material absorbs mechanical stress.
  • The sealant should provide minimal shrinkage.
