Our range of uPVC windows provide great energy efficiency, meaning they’ll make sure that no heat escapes and no chill gets into any London and Croydon properties. But they also make sure things won’t get too hot in the height of summer! The glazed panels effectively control heat entry and heat exit. Our window frames use an optimised ventilation system to ensure that the room remains at a pleasant temperature, no matter what is going on outside!

The thermal performance is optimised in all aspects of the Kommerling design, which means that homes that implement our flush casement windows can become less reliant on central heating and air conditioning. The only thing better than reduced energy bills and a reduced carbon footprint is the reduced effort that’s needed to keep the temperature comfortable!

All of our Kommerling flush casement windows are specifically designed and manufactured to support the use of special security fittings and additional anti-burglary measures. Security is an important concern in any construction project in London and Croydon, and our range of flush casement windows is certainly up to the task.

As well as offering excellent protection from would-be intruders, our range of flush casement windows also offer superior soundproofing, with sound insulation of up to 42 decibels. Just like how they keep the heat in and the cold out, they’ll keep private conversations inside and external noise outside. A must in London and the surrounding areas!
