44 DER #aluminium Flush Casement #Windows and a DER French Door in anthracite grey have been fitted in a substantial residential property in Leeds. The job was carried out by local Leeds installer Abbey Windows and fabricated by Kingfisher Windows and the end result is incredible!

“DER is a superior aluminium window and door system and the slimline, flush aesthetics make it an attractive product to sell to our customers. The low-level gaskets mean the frames look even slimmer, which taps into the trend for big expanses of glass which are so popular at the moment and the flush aesthetics present a straightforward sell. It is a stand-out aluminium product.” - Darren Capitano, owner of Abbey Windows.

DER offers installers a clear point of differentiation when selling into the consumer. Similarly, the ease of fitting has proven popular with installers too!

“The positive comments from Abbey Windows is typical of the feedback we have been receiving for DER across our #trade, retail and commercial customers. It’s an intelligently-designed system that offers clear benefits for our customers across all market sectors. It’s clear that DER is delivering what the market needs.” - Deborah Beeley, Kingfisher Windows.
