At K Parker Joinery, our Premier range caters for both SINGLE and DOUBLE Glazing.
Our Premier range of windows has passed the Mechanical Sans 613 performance test and offers weather seals, satin chrome or brass fittings.
Our Premier range of windows has been simulated using the latest technology with over 240 combinations of SINGLE and DOUBLE glazing.
Please enquire if you have other requirements.
The above results have been tested and backed up by the Rotatable Guarded Hot Box (Sans204).
The standard range of simulations can be transferred to custom windows in most cases.
Windows can be custom made to suit your requirements.
