Oak Frame Cornwall by Stephane Roux Ltd


Stephane Roux Ltd utilises the direct glazing method when applying glass to a heavy structural timber frame. Face applied glazing or direct glazing is the industry standard for this type of structure and the most fail proof.


Direct glazing basically consists of glass units sandwiched to the outside of the frame by seasoned oak coverboards. However, there many ways of achieving this. The correct method will insure a frame staying dry, looking and staying aesthetically pleasing against one that doesn’t. Poorly realized direct glazing can leak and look shoddy after as little as a year. Badly thought out installations with cheap fixings result in difficult to replace units which can fail prematurely. With the correct procedure applied units last 25 years plus and can be easily replaced if broken (strimmers and lawnmowers being the common culprit). They stay dry and aesthetically pleasing for decades to come.

Method used

Stephane Roux Ltd utilises a dry glazed method. This means no silicon or mastics which can degrade or tear and with drainage built into the system. Not only is this more environmentally friendly but is also extends the life for the glazed units.

General specification:

  •  36mm seasoned European joinery grade oak cover boards with a planed finish left to grey naturally
  • Cover boards secured with M8 SPAX stainless steel washer head T star screws, counterbored and cross grain pelleted
  • Durable softwood packers
  • EPDM black rubber dry glazing gasket
  • 0.6 mm copper flashings
  • 4-20-4 or 6-16-6 toughened safety glass, low-E, warm edge spacers, argon filled IGU’s
  • European painted softwood joinery (Rationel Domus) Quality locally made joinery units also available.

Key Features of the system used

The entire structural frame is clad providing a continuous waterproof seal. The glazed units are floating on EPDM rubber seals allowing for movement of the structural timber frame. Drainage is built into the system and copper flashings utilised over lead or zinc as both lead and zinc react with acidic timbers. Furthermore lead is poisonous therefore it should not be used where it can be in contact with people. Stephane Roux Ltd offers the choice between “bright” copper that develops and changes in the environment or a more predictable pre-oxidised copper for all flashing details. For all joinery elements, rebates in the structural timber frame are formed improving performance and the aesthetics of the installation. Both double and triple glazed installations are possible.
