Choose Windows That Fit Your House & Needs


Everest offer a fully customisable window solution. You can tailor almost every aspect (material, style, glazing, colour, hardware, glass type) to match your energy-efficiency goals, home’s architecture, and aesthetic preferences.

Everest Window Styles

Your new window style should match the architecture of your house and your functional needs.

Storm Casement

Storm Casement windows are our most versatile, available in a range of colours and designs to match your homes individual style. Can be personalised to match all budgets.

Flush Casement

Flush casement windows have a sleeker and cleaner “flush-in-frame” look, good for modern and period mix properties.

Sliding Sash

Sash windows are more traditional / classical, good for older or period properties; available in uPVC or timber.

Tilt & Turn

Inward-opening or tilting for ventilation and easy cleaning. Practical for flats, upper floors or modern builds.

Bay Windows

Bay windows add architectural interest and more light/space to your home. Frames can be matched to other windows.

Secondary Glazing

Improve insulation for listed buildings or conservation areas where replacing the original windows is restricted or undesired.

Everest Frame Material

When choosing your frame material, consider key factors such as energy efficiency, durability, maintenance needs, and the overall aesthetics and style you want to achieve.

uPVC

Our uPVC windows are low-maintenance, highly secure, with good energy efficiency, and offer a wide colour/finish range.

Timber

Our Timber windows are made with traditional styling, perfect for period homes. Choose from a wide range of RAL paint and stain colours.

Aluminium

Our Aluminium range offers slim, modern frames with large glass area, strong and weather-resistant, and are low maintenance.

Everest Customisation

This level of customisation allows windows to match a wide range of property styles — from modern builds to heritage / period houses.

Double and Triple Glazing

Double glazing has a good standard insulation, while triple glazing delivers greater efficiency with lower U-values and better heat retention.

Colour Choices

Choose from an array of colours, woodgrain finishes (on uPVC or timber) and dual-colour frames (different inside and outside colours).

Window Hardware

Choice of hardware & finishes lets you pick between functionality, security, and emphasis on looks.

Privacy & Obscure Glass

Obscure glass covers a type of glass that includes frosted glass, patterned glass, textured glass and privacy glass.

Leaded Glass & Georgian Bar

We create square, diamond, and custom leaded glass windows, plus elegant Georgian bar designs for added traditional charm.

Decorative Glass

Our decorative glass options provide you with almost an infinite number of designs and styles to choose from.
