Our modern uPVC sliding sash windows marry the vintage charm of sliding sash windows with the modern expectancy of leading thermal efficiency.

The sliding sash windows supplied by Best Value Windows use the very best hardware, including top-of-the-range operating mechanisms, which make the hand-built PVCU windows virtually indistinguishable from the timber windows they could be replacing.

We appreciate that the finished product is not always the reason why you would chose a replacement sash window. A lot of other factors are considered such as price, quality and delivery times, however we would like to bring your attention to a few of the intricate aesthetic detail which we think sets our windows apart from the rest of the competition.

The sculpted system was created to give the window an almost perfect aesthetic finish and a look of elegance rarely found with ‘building products’. These curves tend to soften the appearance of the window and make it much more attractive to look at.

In addition to this the system also offers very slim profile sections in terms of the jambs, sash sections and mid-rail to recreate and mimic the ‘traditional timber sash window’ as much as possible. The basic design and purpose of the window is to be as sympathetic to the aesthetics of an original sash window but without the huge price tag.
