Window Styles
A window style is the descriptor used to describe how a window opens or where it is hinged, are Casement, Sash, Tilt & Turn and the newest, Flush.
Casement Windows
Opening outwards, these windows are hinged at the top or the side and can sit either flush within the frame creating a flat surface from the outside creating establishing a more modern look or can be a traditional fit to create a more classical aesthetic.
The perfect all-rounder, with adaptability of layouts and designs, a casement window allows you to have control and to choose a design, whether jazzy or plain, that suits you and your home, making you happy for years to come.
Tilt & Turn
Hinged at both the bottom and the side, this style of window is a master of flexibility and adjustment. Hinged at the bottom these windows tilt into the room to allow for ventilation, however with the turn of the handle they utilize the side hinges to allow the window to swing fully into the room for extra ventilation and easy cleaning.
These windows are perfect for when your outdoor space is limited and you live on a higher floor where cleaning the windows isn’t so practical.
Sash Windows
Sash windows typically have two panes, one that is vertically over the other where both panes can slide to allow for ventilation from top or bottom.

Fitted with the best possible hardware, sturdy hinges, locking handles and high security locks, Optima meets the high standards of hardware that is required by the ’ Secured by Design scheme. You don’t have to comprise the safety of your home for style but rather choose a product that impeccably combines both practicality and style.

Energy Efficient
We all try to be more energy conscious, whether it is to reduce carbon footprint or to save money on energy bills, ensuring that you have the right windows is only going to improve your home energy efficiency. Designed with performance as the first priority, REAL Aluminium windows offer superior thermal efficiency utilising energy efficient glass.

Double Glazed Energy Efficient Units
It’s never been more important to try and reduce your carbon footprint but ensuring that your home is as energy efficient as possible. Not only is this good for the planet but it means that you’ll reduce your energy bills and keep your home warmer in the winter.
In our double and triple glazed units we use low iron and a low-E softcoat glass that utilizes advanced coatings to retain warmth from within the home whilst also allowing for natural heat from daylight to be captured. They also include a Warm Edge Spacer bar made from a highly insulating composite plastic that reduces the thermal bridge between the two panes of glass, thereby reducing condensation and cold spots. Finally the units are filled with argon gas which is a colourless, odourless and tasteless gas that provides optimum thermal insulation whilst being both non-toxic and inert. Using argon gas in our products allows them to achieve a higher energy rating compared to units using air.
26% of all domestic heat loss is through the windows, which is a staggering event and improper efficiency means your energy bills can increase. Choosing a window that is energy efficient and offers warmth retention is imperative for an efficient and warm home. On average 22% on energy bills are saved* when using energy efficient double glazed glass.
*22% savings are typical but each home will vary. Example is for a semi-detached, 3 bedroom UK home saving £179 per annum for an A rated window (source Glass & Glazing Federation and Energy Saving Trust) with an annual gas bill of £800 (source: Department of Energy and Climate Change).

Triple Glazed Windows Windows
Triple glazing is well established in many parts of Europe and is becoming increasingly popular in the UK. The windows are more energy-efficient than modern double glazing. The additional pane of glass and gas filled cavity provides enhanced insulation.
Triple glazed windows can also provide outstanding acoustic performance, minimising noise levels from outside. This could benefit you if you live close to a road or in a densely populated area.
