Selectaglaze supplies sensitive secondary glazing; the primary choice for Listed former Mill


However, its history goes back considerably further. In the 11th century, it was recorded in Domesday as the water mill at Benton Hall, a subsidiary manor of Blunts in Witham. Today, it has been reinstated to its 18th century version, with surviving machinery used as adornments and effective monuments to pay homage to the proud history of Blue Mills. The turret clock which was purchased by previous owner Dr Grabham in the post milling era is still in place and in full working order.

The recent owners have lived in Blue Mills for almost 20 years and required a thermal solution, with acoustic  benefits to make their home at the mill more comfortable. The thermally inefficient primary windows across most of the house did little to retain heat.


The owners reached out to Selectaglaze for advice on the best possible treatments for their primary windows; a mixture of timber sash windows, fixed lights and inward or outward opening casements. The quirks and  irregularities around some of the bay windows meant that a considered approach was required. Maldon District Council confirmed that no formal listed building consent was required for the works.

22 windows have been treated thus far using a number of window styles: fixed light, vertical sliding and side-hung casements. Two windows in the wood-panelled room were treated with Selectaglaze’s heritage Series 47 hinged casement system which was able to sit tight behind the wooden shutters, allowing their continued operation. The aluminium profiles were coloured in a woodgrain finish which colour matched the existing surrounds perfectly.  

The stunning Billiard Room was fitted with four Series 45 side hung casements. Additionally a Series 25 vertical  sliding unit was installed as one of the windows in the Billiard Room was larger than the other. The front door was treated with a mixture of two Series 42 fixed light units on either side of a Series 41 double-side hung casement, whilst the rear door was fitted with a Series 41 side hung casement. The bay windows on the ground and first floors were the most challenging treatments because the primary windows were not plumb and true, due to the age of the building. In order to prepare the bay windows for the secondary glazing, tapered timbers were fixed to the openings to square up the reveals.

“We have been impressed by the design of the windows and frames and the bespoke options.  External noise has been all but eliminated and the air tight fittings and  thickness of glass will significantly reduce our energy bill. Initially we were focused on the windows at the back of the house but were so pleased with the outcome we doubled our order to include the front upper levels of the Georgian house. The Selectaglaze product has transformed the living experience of our home.”
