Double glazed sashes Cumbria Wildlife Trust, Kendal

We have just completed the first phase of works at Cumbria Wildlife Trust, Kendal, Cumbria. After upgrading their heating systems they wanted windows that would be far more energy efficient than the existing single glazed Georgian sashes. We manufactured new spele hardwood sashes containing warm edge low e argon gas filled units, drastically improving the thermal efficiency. We finished the sashes in two colours white on the inside and Valley Rock on the outside.
