Rowan Timber window range offers a high level of quality which is monitored and maintained through the quality standard of ISO 9001: 2000. The standard assures that an independent accredited body continually monitors us.
Rowan Timber windows are all A rated and ideally suited to meet the recent changes to Scottish Building Regulations Part J which requires all new windows in extensions and replacement windows, sold to the domestic market in Scotland, to have window energy rating (WER) of ‘C’ or above.
Two factors are considered in WER, the ‘g’ value and the ‘U’ value. Rowan Timber windows use Pilkington K Glass, which is designed to reflect heat back into the building, greatly improving its thermal efficiency and also maximising the use of the available heat from the sun, thereby helping to meet these new regulations. Pilkington K Glass is the leading low E glass in the UK.

- Rowan Fully Reversible
