The traditional vertical straight sliding window has been made for the last 300 years or more, in our window however, we have two modifications.

One is that the sashes are operated by spiral balances as opposed to weights and pulleys, although these can be incorporated if required, (Albeit at an additional cost). The other is that we have applied up to date technology and design to the seals, on both the weatherproofing and sound insulation.

The sashes are secured with a solid brass Fitch Fastener.
