The benefits of Timber Casement Windows

Warmer and quieter timber windows

Warmer and quieter

Timber naturally suppresses sound and when combined with a 20mm argon-filled gap and multiple seals, noise is significantly reduced. Our timber casement windows also include draught-resistant seals for extra warmth and savings on your energy bills.

Easy to maintain

All Everest timber products are are easy to maintain, requiring very little care to keep them looking good for years to come. We also use micro-porous paint and stain finishes to protect your new windows from the elements. They really do last longer – as our long guarantees attest to.

Everest's latest customer reviews


Q: What glass options can I choose from?

You can select from five different types of glass with our timber casement windows. These are: obscure, decorative, security, safety or anti-sun.

Q: Are timber casement windows secure?

They include security features that exceed British Standards, so you can enjoy complete peace of mind.

Q: Is the timber used for timber casement windows sustainably sourced?

Yes – all  the timber we use to create your timber casement windows is accredited by the Forestry Stewardship Council (FSC). They ensure all timber used is sustainably sourced.

Q: What paint and stain finishes do you use?

We offer a range of micro-porous stains and paint finishes to keep the windows looking fresh for many years to come. These protect your new windows from the elements and make them easy to maintain.

Q: How often do timber windows need to be cleaned?

All of our timber frames are made from specifically selected, seasoned wood. Timber has natural properties which help it withstand the elements and in the factory we apply a ‘colour harmonising’ finish containing a preservative. We then apply a micro-porous protective stain or paint finish. However, timber is a natural material so requires regular attention to keep them looking good. You should carry out cleaning regularly, at least twice a year. The factory applied coating systems will give many years of life between repainting cycles and simple steps, such as wiping down the product to remove dirt and insects will help to extend the decorative finish. Washing your windows regularly with soap and water can add years of life to your timber windows.
