Sharp Glazing strive for the very highest standards in the work we do and in the installations that we provide. One way that we are able to guarantee those standards is through our membership of the organisations that oversee and regulate our industry. Our membership of the Glass and Glazing Federation, its offshoot the Fenestration Self-Assessment Scheme – commonly referred to as FENSA – the approval of our products (EcoDiamond™ and Sliding Sash windows) by the Energy Saving Trust, and the validation of our workmanship by the TrustMark scheme are a way to ensure that every aspect of our work is at the forefront of our industry.
