A Special Late Summer Offer

Wednesday, August 29th , 2018


We are celebrating our 20th birthday with a late summer promotion and offering all customers the authentic super slim meeting rail FREE on every Bygone Harmony or Symphony window purchased up until 12th October 2018.

The slim meeting rail is an optional extra on Harmony and a standard feature on the Symphony range.  This means that customers will get a FREE upgrade on Harmony or a discount to match the cost of the Harmony upgrade on any Symphony purchase. 

Bygone sash windows complete with the 39 mm slim meeting rail are the perfect low maintenance alternative to timber windows and suitable for installation in Conservation Areas.

This special celebratory offer is only available from the Bygone network of approved installers – nationwide!
