Green Red - Brown Grey - Dark White - Creamy Blue Sash/Vertical sliding Timber/Wood

Technical Specification


The John Watson Joinery Mock-Sash Casement window offers all the features of a modern high performance timber window.

Based on our Stormproof window and utilising scribed sash horns to maintain the traditional appearance, this is a viable alternative to a traditional style. A dummy sash to the bottom fixed pane ensures equal sight lines further mimicking the design of a Vertical Slider.

Sashes open as per normal Casement Windows (top hung) but when closed, suggest the look of more traditional sliding sash windows.

The range incorporates:

A Double Gasket Unit for storm proofing
Vented and drained frame & sash with double Silicone Seal
Trickle Vents & Glazing pins
Fire egress facility as Standard

Locking System:
Like our Stormproof Windows, our Open- Out Mock Sash Windows utilise mushroom bolts and shootbolts.
Our standard espagnolette locking systems have achieved more than 7.4Kn which is more than double the requirements of BS7950.

Mock Sash WindowDrainage:
Using the same principles as our other timber product suites, the Mock Sash benefits from dry gasket glazed drained glazing rebates allowing any moisture ingress to ventilate to the outside.
For high exposure areas, aluminium bottom beads can replace the traditional bottom beads. Our Sales & Estimating Teams are happy to advise to meet specific project solutions.

BS 7950 Security:
Our Mock Sash Window utilises the same high specification ironmongery that achieves the BS 7950 certification on our Open Out Stormproof window but has yet to be tested in its own right.
