What Is A Casement Window?



What Is A Casement Window And What Are They Used For?

Casement windows are the most popular type of window in the UK and come in a range of styles to suit any home. Double-glazed casement windows are easy to install, convenient to maintain, airtight, and secure, providing excellent value for money. In this article, we run through the main features and advantages of casement windows, and how they compare to alternative window styles.


What are casement windows?

Casement windows provide effective ventilation for any room using an easy-open top or side-mounted hinge. The four types of casement window are:


1) Top-opening, or awning windows – typically small letterbox shaped windows that provide ventilation above a larger, fixed windowpane, although larger rectangular awning windows are also available.

2) Size-opening windows that open outwards to provide maximum ventilation and, in some cases, an emergency exit.

3) Bottom-opening, or hopper windows – a less commonly used style that pivots outwards from a bottom-mounted hinge. Suitable for upper story rooms to provide increased safety and security.

4) Fixed casement window – a non-opening windowpane installed to provide decoration and draw natural light into a room. Fixed windows are normally accompanied by one or more functioning windowpanes.

Double-glazed casement windows may include a combination of a fixed pane, plus two or three movable windows with top opening or side opening hinges. Casement windows allow for a wide variety of designs to accommodate the style and ventilation needs of your home.


Advantages of casement windows

  • Available in a wide range of durable materials and finishes.
  • Weather-resistant, low maintenance style.
  • Compatible with double- triple- and single-glazed window panels.
  • Excellent energy efficiency and thermal insulation rating.
  • Cost effective to purchase and easy to install in any window space.
  • Energy-efficient double-glazed casement windows could add between 5% to 10% value to your home.
  • Lockable and secure, providing a tough barrier to would-be thieves.




Alternative window designs – are casement windows better?

Despite their historic popularity, casement windows aren’t the only type of window available. Other styles include:

Tilt and turn windows vs casement

Tilt and turn windows are a versatile modern style that are capable of opening from either a bottom-mounted or side-mounted hinge, depending on how the window and handle are ‘tilted’. Many people find tilt and turn windows a practical alternative to casements for inward-opening windows, as they provide good ventilation and easy-access for cleaning.

Sash windows vs casement

Sash windows are an

elegant 18th and 19th century style of window consisting of a movable pane of glass set below and slightly behind a fixed pane. In a vertical sash window – the most common style – the windows open by moving the bottom pane up to where it stacks behind the fixed upper pane.

Traditional sash windows were assembled from multiple small single-glazed panes, but their modern successors use individual sheets of glass, often partitioned to give the effect of a multi-paned Georgian window. Sash windows are still often found in historic Victorian, Regency, and Georgian houses (as well as pubs and some offices), but look out of place in most modern builds, and do not have the versatility of casement windows.

Fush sash windows vs casement

These have been more recently developed in modern materials to mimic traditional timber windows of the past where the opening sash does not protrude relative to the frame, but lies flush within it, giving a sleek and modern finish, while maintaining weather and security specifications.

How much do casement windows cost?

Casement windows vary in cost, with the price depending on several factors:

  • The size of the window.
  • The material of the window frame – e.g. UPVC, wood, or aluminium.
  • Glazing options – e.g. single- double- or triple-glazed
  • Optional add-ons – e.g. extra security features, weatherproof coatings, child locks, soundproofing, tinted windows etc.

As a costing guide, replacing all the windows of a typical three-bedroom house with double-glazed UPVC casement windows starts from around £4,000.

Bifold Doors Vs Sliding Doors – Which Should You Pick & Why?

Bifold Doors Vs Sliding Doors – Which Should You Pick & Why?

    Bifold doors and sliding doors (also known as in line sliding patio doors or 2,3 or 4 pane sliders) are tall, fully glazed doorways available in upvc or more popular nowadays, aluminium. They are usually positioned to allow access to the garden or conservatory. Both types of doors are perfect for letting light and warmth into the house, and for creating a seamless transition between home and garden, so the bifold versus sliding doors choice is mostly one of personal preference. Both types of doors create a good connection between indoor and outdoor spaces, provide plenty of beautiful natural light, and come in a range of modern styles. They both operate in a different way, however, so in this article we present a comparison of the pros and cons of each choice. What is a bifold door? Bifold doors comprise two or more door panels, or leaves, attached to the door frame on a sliding carriage track along the bottom or the top. When the doors are opened, they fold in or out on themselves, creating a v-shape, and stack together in a concertina-style when fully opened. Pros The entire doorway can be made into an opening – unlike sliding doors, in which one or more panes are always shut. The amount of opening space can be varied, with the bifold extended to allow the desired space. Wide range of styles and configurations to fit all available spaces. Different designs open inwards or outwards. Lightweight and easy to install. Increases the value of the home. Cons Requires enough space for the concertina stack either inside or outside the building, equivalent to the width of each door pane. Large spaces will need multiple door panels, resulting in a large stack when fully open, and potentially obscuring the view to the garden. What is a sliding door Sliding doors comprise two or more sliding panels and, like bifold doors, are mounted onto a track at the bottom of the frame, but this is where the similarities end. Sliding doors are designed to slide horizontally along the track without stacking, so that when open, one door sits in front of the other. Sliding doors consist of movable sides and one permanently fixed side, so the door only ever opens on one side of the doorway. ( A French door, on the other hand, has two identical panes that can both be opened). Pros Provide a broad view of the garden or patio with minimal interruption. The opening space can be adjusted to provide access, or simply to let fresh air into the house. Lightweight, modern style. Does not require an outward or inward opening space, so are perfect for smaller areas. Cons Doors only ever open on one side. The large, unbroken expanse of glass may pose a safety issue for children or animals. Making the right choice for your home At Harvey’s Windows, we install beautiful, high quality sliding doors and bifold doors for our customers in the Leicestershire area. We consider both to be fantastic choices for garden and patio access and would be delighted to help you choose a style and door type that suits your home.

Composite Doors Vs UPVC Doors - The Pros and Cons of Each

Composite Doors Vs UPVC Doors - The Pros and Cons of Each

    In this article, we will cover front doors. As the main entranceway to your home, choosing a replacement front door is a big decision; one that must consider security, durability, and ease of access, as well as aesthetic appearance. Of all the options available, composite doors and UPVC doors are the most versatile, long lasting, and cost-effective – with pure timber doors rarely used these days. Let’s start by explaining what each type of door is, before looking at the pros and cons of each. Composite doors Composite front doors are made from a thermally efficient and secure high density foam core, coated with a thick layer of waterproof glass-reinforced plastic (GRP). This gives composite doors the look and feel of wooden doors, but with added durability and heat retention characteristics – as well as a longer service life. The materials are joined together under high pressure to form an extremely strong door, and there are many different styles available to suit different properties and tastes, from the ultra-traditional to sleek, modern designs. Advantages Stronger than both pure timber doors and UPVC doors – composite doors provide a strong deterrent to thieves, and offer the best level of security. Your door can be personalised with custom accessories, glazing styles, and a variety of natural wood finishes or colours to suit your personal tastes. Composite doors have the beauty and class of traditional wooden doors, but retain their appearance for far longer. A wide range of colours and glazing options available. Better heat retention than timber doors, leading to lower heating bills. The anticipated lifespan of these doors is at least 25 years Disadvantages Composite doors are more expensive than their UPVC equivalents. As partially wooden structures, some composite doors have a lower fire safety rating than fully plastic UPVC doors. UPVC doors Unplasticised polyvinyl chloride (UPVC) doors are moulded from a tough, durable polymer/plastic material into a variety of colours and styles. UPVC doors are cheap to produce and provide excellent long-term value for money, being resistant to the elements and changes in temperature. As front doors, they offer a decent level of security and privacy, and can be supplemented with a range of glazing options. Advantages Fully customisable – ‘traditional’ UPVC doors usually came in white, but modern fabrication methods allow a better selection of colours, styles and imitation finishes, including various realistic wood grains. UPVC doors consist of a tough shell with a foam filled interior reinforced with a 4mm core of MDF, and double-glazed panes, providing an excellent level of insulation at the entrance to the home. UPVC itself is a poor conductor of heat, which minimises internal heat loss in winter and helps keep the house cool in summer. Exceptionally low maintenance compared with traditional wooden doors – no repainting, varnishing, or finishing required. UPVC doors display little to no sign of weathering, and just need an occasional clean. Sustainable investment – a UPVC front door and window could last 40 years or more and is recyclable at end of life. UPVC doors have a good soundproofing rating, reducing external noise by up to 50%. Cheaper than composite doors. Disadvantages Some UPVC door designs have a cheap ‘plastic’ appearance. UPVC doors do not have the same level of security and strength as composite doors, and are unlikely to resist a determined break in. Attractive and durable front doors from Harvey’s Windows At Harvey’s Windows, we offer customers a range of UPVC double glazed composite doors to suit every budget, personal taste, and security requirement. Overall, composite doors – although more expensive – provide better long-term value for money, greater security, and better energy efficiency than most standard UPVC front doors. However, if you are unsure of the door you require, or ...

What Is The Difference Between An Orangery And A Conservatory?

What Is The Difference Between An Orangery And A Conservatory?

    Orangeries and conservatories make gorgeous additions to a home; sun drenched rooms that can be enjoyed throughout the year, and a great way of adding value to a property, too. Most people are familiar with a conservatory and what it looks like, but what is an orangery, and what is the difference between a conservatory and an orangery? Both are predominantly glass-based rooms built to adjoin the main home, but there are a few differences worth considering. In this article, we explain the differences between orangeries and conservatories, and the pros and cons of each, as a quick guide for people considering investing in one of these wonderful structures.  For a quote, or to discuss the matter further, please don’t hesitate to give one of our customer service advisors a call. What is an orangery? An orangery is a brick structure with big windows and a flat roof, onto which is built a four-sided glass ‘lantern’. As the name suggests, orangeries were originally designed as large, sunlit rooms in which to grow exotic plants and citrus fruits, and they became popular among English stately homes in the 19th century. Classic orangeries were built as south-facing structures to maximise sunlight and included substantial windows on the walls and ceiling – but also featured strong brick-built walls and an insulated roof to minimise heat loss overnight. In the days before double-glazing, orangeries were warmer than conservatories and usable throughout the year. Key features Stand-alone structure, or built against the main wall of the house, with a door adjoining the main home, or the modern version which tends to be open plan with the house. Multiple tall windows in each wall, comprising up to 50% of the available wall space. Flat solid roof with a glass lantern, comprising up to 75% glass. Rectangular or square layout. Built to match the style of the property. Advantages Orangeries are grand structures that add an air of sophistication and elegance to any home. Fully usable rooms that are adaptable to any purpose, including dining rooms, living rooms, play- and games-rooms etc. Better heat retention than conservatories, making them more energy efficient and comfortable to use on colder days. Less prone to damp and mould than conservatories. More secluded and private than a conservatory. Disadvantages More expensive than a conservatory. Takes longer to design and construct. There are more planning permission and building regulation implications with an orangery construction which take time and cost money Costs and planning permission Orangeries vary in price from £20,000 for small rooms to £100,000 or more for the largest structures, with an average in the range of £25,000 - £50,000. An attractive and well-built orangery may add as much value to your property as a full extension. As single-storey structures, some orangeries are covered under permitted development rules and do not require planning permission, but please consult an orangery and conservatory specialist such as Harveys Windows, before undertaking any building work. What is a conservatory? A conservatory is a fully glazed room built against the main wall of the property, with usually a low brick wall and base, and a design that maximises the amount of glass and sunlight. Like orangeries, conservatories became popular in the mid-19th century and were initially intended as greenhouses in which to grow plants, and relax in the increased ambient warmth. This is how many homeowners still use their conservatories, as they are perfect sun-traps and provide an ideal environment for house plants, sleeping pets, leisurely lunches, and luxurious coffee breaks! The classic Victorian design was updated in the 1970s to the elegant steep-roofed design used by most conservatories today. Key features A fully glazed building constructed on a low brick base and surrounding wall. Walls comprise of 50% + glass. Sloping or pitc...
