Timber Casement Windows

A warm look and feel to enhance your interior and exterior

Windows made of hardwood continue to be highly desired among homeowners, chiefly thanks to the beautiful, warm look and feel, which enhances all kinds of interior.

 

What’s the difference between casement and stormproof?

Casement windows sit flush against their timber frame, hence the name “flush casement”. Sitting flush means that there’s no difference in height between the frame and the window.

The stormproof range’s window juts out of their frame, adding extra thickness and defence against strong weather.

  • You can choose from four different sash types to frame your glass.
  • Each hardwood casement window features mushroom bolts and shootbolts for better security.
  • There’s a range of glass panels to choose to suit your window. Chose from a single or double glazed, which provides an A-rated energy rating standard.

Hardwood versus softwood

As the name suggests, hardwood is much more durable than softwood, which is why it’s such an excellent choice for those seeking a timber casement window. To illustrate, an untreated, unpainted hardwood timber window would be expected to last 15 to 40 years above ground in the UK’s temperate climate. An untreated, unpainted softwood window would last up to seven years.

Of course, both hardwood and softwood windows are indeed painted and stained, extending their respective lifetimes by many years.

However, the issue with softwood relates to durability. In this instance, by durability, we mean a wood’s ability to withstand rot and wood-eating insects. While wood-eating insects are not a significant problem in the UK, in our damp, wet climate, decay certainly is. Once fitted, softwood windows are likely to have fittings screwed into them, which permeates the paint and stain, leaving the window vulnerable to rot.

The same is not true of hardwood windows, which possess natural preservative qualities. These properties stay in the wood and extend to its very core. When the hardwood’s natural durability is married with painting and staining, you get a hardwood that lasts several decades.

Here at Osborn Glass our hardwood casement windows are manufactured using highly durable hardwoods and are then protected with the latest in microporous paint and staining systems.
