Using a Sash Window

Gone are the days when you had to fight to open a sash window. These days the vertical sliding panes move up and down in precision tracks designed for ease of movement.

Another older fault was with the counterweights build into the frames. These used to be cast iron weights attached by ropes & pulley wheels to the window.

Although you can still get timber sash windows operated by counterweights, most UPVC examples make use of spring loaded tensioners.

UPVC sash window can also be built to have a tiling function which, not only provides for ventilation, but also makes the outside glass very easy to access for cleaning.

Coloured Sash Window & Glazing Options

Timber Box Sash units, as you would expect, can be painted or stained to almost any colour you like.

UPVC versions will give you a choice of up to about 10 or so (depending on the supplier), such as light oak, Irish oak, rosewood & mahogany.

Wood-grain surfaces are also popular as they recreate the look of a traditional timber window.

Glass can be clear or opaque, with options for patterned or leaded lights (panes) & Double Glazing will come as standard. Glass can also be upgraded to low emissivity energy saving glass or even Argon filled sealed units for extra energy efficiency.

Front & Back Doors

In terms of front doors, most householders want to have a nice one that makes a god impression upon visitors or passers-by.

The most popular options for front doors are hardwood or UPVC.

Hardwood doors are a good option, but a lot of folks think they are expensive and that may not be the case as you can find them at approximately the same price as a UPVC Composite Door circa £500 to £600 – supply only.

UPVC front doors can be very cheap for supply only, but at the lower end of the market you may get less quality.

The higher end price for UPVC front doors would be Composite versions. These are fantastic looking entrances that are very tough, energy efficient & secure.

Patio Doors

There are 2 main differences in design to choose from such and that would be whether you want a sliding door or one that is hinged at the sides.

A typical patio door would be a sliding patio door or Bifold version and the most popular hinged type would be a French patio door or a Tilt / Turn Door.

The design that would give you the biggest clear space when opened would be the bifold door. The panels fold to the sides to give an amazing up to 90% clear opening.

For French doors being used in a wide opening, you would probably need to fit side panels, as each standard door of the pair would be around 3 feet wide.

A standard front door is between 2ft 6ins to 2ft 9ins wide, so any opening over 8 feet could need a side panel.
