Double Glazed Units have been around for many years and is known to provide insulation. However the degree or amount of insulation that can be provided is not widely known and is the most important factor in today's escalating heating costs (see note below).
By adapting and maximising the latest technology a double glazed unit can be produced which is very slim with an overall perimeter seal depth of 5mm, suitable for most single glazed windows, and most importantly with unbeatable insulation properties.
Rising Energy Costs
A recent commissioned report claims that since de-regulation of prices in 2002 and from 2002 to 2005 average energy prices have risen by about 60% more than inflation.
Figures published in 2005 stated that replacing single glazing with Low E Double Glazed Units will provide payback in 3 years, presumably less in 2008.
Replacing one square metre of single glazing with Low E Double Glazing will produce a saving of approximately 90Kg of carbon dioxide emissions per year.
How its done
Double Glazing Original Timber Sash and Casement windows
We first delicately remove the old putty and the old single pain glass.
Next we route in 2mm or 3mm from the rebate without detracting from the physical appearance of the windows to accommodate the new slim double glazed unit.
Using security glazing tape and butyl tape we bed the new slim double glazed unit into the frame and finish with a hard wood beading.
Beaded and painted to finish.
To finish we preserve, prime, undercoat and top coat paint using Dulux Weathershield system (unless a specific paint or colour is requested)
New Sliding Casements
When an old window is too damaged or rotten to accept the new double glazed unit we can supply and fit new bespoke hardwood sliding casements to fit into the existing sash box. See our Bespoke Joinery page for more details.

Sash Weights and Sash Cord
When replacing old single pain glass with slim double glazing the overall weight of the window increases so the sash weight have to be changed and the window re-corded and re-balanced to accommodate the extra weight.
