Thermally Efficient Products

The Sternfenster range of products has been designed to offer an impressive degree of thermal efficiency, combining a thermally broken profile, high-performance weather seals, and professional installation to ensure the warmth from your central heating stays in your property for a longer period of time. This means that you’ll be able to keep those winter winds at bay without having to worry about letting the elements in!

Not only does this design work to keep the winds at bay, but the high-performance weather seals also work to keep draughts and water ingress out of your home too. This is important, as water ingress can cause a build-up of mould and damp which can cause structural problems for your windows and doors. However, this isn’t something that you’ll have to worry about when it comes to getting a window or door from Sternfenster.

Alongside this, investing in this standard of thermal efficiency for your home could also see you saving money on your heating costs too! This is because the warmth from your central heating is going to stay in your home for a longer period of time, so you could find that you rely on it less frequently to keep your home at the optimum temperature. Alongside this, your reduced energy use could also see you lowering your carbon footprint too!

High-Security Products

Sternfenster products combine premium grade materials and high-security locking systems to ensure they can achieve an impressive standard of structural integrity and protection for your home. The inherent security that is achieved through high quality materials enables them to withstand impact attacks. Also, the integrated, high-security locking systems are fitted into the frame to ensure they can’t be easily accessed by a would-be intruder as a point of leverage.
