A silicone system for draught proofing steel frame windows has been developed by our company and has been successfully applied to many properties such as schools and commercial buildings.
Firstly the windows are serviced so that they open and close properly. We then apply a coat of metal enamel paint to the rebate and a release agent to the opening sash, liquid silicone is then gunned to the rebate on the window frame. The sash is then closed and any excess silicone trimmed and left till the silicone has cured. After curing the sash is opened and the cured silicone has bonded to the rebate creating a form of gasket, but due to the release agent it has not bonded to the opening sash. Thus creating a seal of variable thickness to match the gap between seals and frame.
Over the years we have salvaged many pieces of antique ironmongery and offer these on historic restoration projects to replace missing ironmongery.
What has appeared to be insignificant over-painted ironmongery often, after dipping in our caustic tank, reveals interesting and in many instances irreplaceable items in brass, bronze and cast iron? If you are missing authentic ironmongery for a special project we may be able to offer something to meet the bill.
