Five chamber profile design
5Stars boasts six chambers (front to back) at the core of its design philosophy. Having two chambers either side of the reinforcement chamber greatly reduces thermal bridging and provides a superb thermal insulation performance.
Acoustic insulation or noise reduction is also much improved so windows manufactured from 5Stars provide the householder with a greater level of all round comfort and well being.
The five chamber construction and resulting thermal performance means that 5Stars is well prepared for any changes to specifications or building regulations calling for enhanced thermal efficiency.
