Listed Building Sash Window Restoration
If your building is listed then the conservation officer may insist that you either replace or restore your box sash windows like for like which means, you will require hardwood window specialists. James Riggall Fine Joinery will liaise direct with the conservation officer on your behalf, to confirm the requirements for your new or restored sash windows, we will then manufacture or restore the windows in accordance with these guidelines making them compliant.
All our box/sliding sash windows are manufactured using the highest grade Sapele, Iroko or Oak hardwoods.
Sash Window Options
Sapele Sash windows
Sapele is reminiscent of Mahogany as it is a member of the same family. It has been given a 40 year approximate lifespan durability by TRADA (The Timber Research and Development Association). We would typically use Sapele hardwood for sash windows that have a hand painted or spray finish and we would recommend to maximise the lifespan of your sash windows, that they are painted every five years.
Iroko Sash Windows
The hardest and most durable of these three hardwoods and does not require regular treatment. It is sometimes referred to as African Teak although, it is unrelated to the Teak family. Iroko is initially yellow in colour however, darkens to a rich brown over time. Although it requires little treatment we would always advise adding a UV protective Osmo Oil as this will prolong the life of the sash window (which, even untreated, will last much longer than our lifetimes!).
Oak Sash Windows
Oak has great strength and hardness, because of its high tannin content it is very resistant to insect and fungal attack. Oak is very popular as it has beautiful markings, particularly when quarter sawn and finished with a UV protection Osmo Oil.
Our windows are built using the traditional wedged mortise and tenon joint, fitted with Aquamac 21 draft excluder and a hardwood sill for extra durability. We only use the highest quality Ironmongery, all hinges and screws are stainless steel and all glass used when double glazing, has a planitherm coating which is designed to absorb the suns heat from the outside and reflects heat from the internal of the building which keeps the room warmer in the winter and cooler in the summer months also giving improved thermal and acoustic efficiency.
We manufacture sash windows which are fully factory fitted with draft excluders into the inside lining on all four sides, parting beads and staff beads eliminating draughts and stopping rattles.
Sliding sash windows can be fitted using either a traditional cord and perfectly balanced counter weight system for smooth easy operation and minimum effort or a modern day spring balance. The windows can be fitted with both locking and non locking catches i.e security vent locks and lockable fitch catches. Internal architraves, linings, cillboards and panelling is all manufactured, supplied and fitted with correct mouldings and details to match the originals.
