Dantaag have been installers of composite windows for over 25 years, working on over 800 projects throughout the UK and overseas.

For all of this time, we were VELFAC Approved Installers and we are proud to say that every time VELFAC carried out an assessment of their approved installers, Dantaag have been assessed to be their No 1 Approved Installer every year since 2004.

Over this time, we were also responsible for introducing other window installers to VELFAC window installation and the training and knowledge we gave them has enabled them to go on to become VELFAC Approved Installers in their own right, with these being APW Glazing Ltd and ADCO Glazing Ltd.

As of January 2020, we took the decision to increase the number of window systems we install and in addition to VELFAC and Rationel windows, we now also install the the very best composite window systems being offered in the UK:

  • Idealcombi
  • NorDan
  • Internorm
  • SAS
  • Janex
  • Outline
  • Uniform
  • Leiab
  • Russell Timber
  • STM
  • Westcoast Windows

We can also install all aluminium, timber & uPVC windows.
