fast, cost-effective, efficient

For renovation purposes a window replacement is the most favourable solution cost-wise and technically. It is frequently underestimated how easy and straightforward a window replacement can be. New windows are quick to install. Besides reducing your heating costs for years to come, you are also protecting the environment. PVC windows are particularly efficient in this respect and rank at the top of the league in eco-balances. (Find out more on this topic on our InfoPage Plastic materials and sustainability).

A replacement of old windows installed 15-20 years ago will enable you to reduce the amount of heat loss by over 40 %. Additional refurbishment of the façade and roof can accomplish even greater energy saving potential.

The following chart shows the average heat loss of older buildings according to floor space and façade area:


Greater comfort - fewer costs

A window replacement in a detached family house pays off after about 8 years and offers enhanced comfort and a feeling of wellbeing.

The example shown here is based on a calculation of average values for a detached family home with a window area of around 40 sqm (status: October 2010). The calculation was based on a heating fuel price of 0.70 Euro per litre. The values have been determined using a standardised calculation method (errors and omissions excepted). If fuel prices rise your investment will pay off even sooner.
