Benefits of a
Casement Window

The casement window is often chosen by homeowners for its practicality, reliability and efficiency. Our casement window reflects radiator heat and absorbs sunlight to create the most efficient A Rating as standard. Replacing standard glazing with our 28mm glass units will dampen outside noise greatly too. Fully reinforced frames, internal beading, multipoint locking systems and lockable handles prevent forced entry.

Maintenance Free

Our UPVC frame requires no painting and little maintenance

10 Year Guarantee

Our window is guaranteed to be faultless for 10 Years

Energy Efficient

A Rated Windows as standard

Opening sashes have locking cranked handles available in white, gold, chrome, satin chrome and black. Fire escape, restrictors or standard friction hinges can be fitted to opening sashes. Roto TSL multipoint locking system is fitted to every opener and can be locked in a slightly ajar position.

Additional Options

Trickle vents have to be specified on new buildings or extensions but for replacement windows they are personal preference. Trickle vents help reduce condensation and allow constant airflow in the room.

A typical casement window will have a mixture of fixed panes and openers. The opening sashes will always stand proud of the fixed panes. Dummy sashes can replace the fixed panes therefore giving the same appearance of an opener, equal sightlines and identical glass sizes.


All windows are double glazed and achieve an A Rating as standard.

The glass is made up of:
- 4mm Saint Gobain Planitherm Total Plus Low E Internally
- 20mm Swiss Spacer & Argon Gas Filling
- 4mm Clear Float Externally


Astragal Bar
The astragal bar option is designed to give the effect of individual panes of glass by using a ‘back-to-back spacer’ inside the glass unit first of all splitting the single unit in to multiple squares without the need for individual units.

Once this grid layout has been included inside the glass unit and the unit fitted in to the window, we then fix a surface mounted PVCu bar to both external faces of the glass unit to give the full authentic appearance.

Georgian Bar
The Internal fretwork is another type of glazing bar used to give an authentic look to the sliding sash windows. This bar is located inside the glass unit and is used to give the window a similar appearance to the astragal bar but with much easier cleaning.

Leaded Options
Natural 9mm lead can be applied to the inside and outside of the external pane in a grid layout suited to your window size and style. Available in square, diamond or queen anne lead designs.

Toughened Glass
Toughened glass is about 5 times stronger than ordinary glass of the same thickness.

Pilkington Toughened Glass is manufactured by subjecting the final glass size to a heating and cooling treatment.

A balance of high compressive stresses at the surface and tensile stresses in the centre of the glass increases its strength.
