Particularly in large cities where space is at a premium, new builds frequently feature comfortable living spaces beneath the roof while loft conversions and extensions are just as popular for existing properties. In both cases quality dormer windows make this possible. Available in a range of shapes, the windows can fit different constructions and project out from the main roof. Ideal for adding interior space, bringing in much natural light, and creating great views out, dormer windows from Neuffer transform loft spaces into bright and well-insulated rooms. With a wide range of quality finishes, shading options, and purpose-designed glazing, they can be easily tailored to match building design as well as various customer priorities.
The Different Types of Dormer Windows
Depending on how a loft conversion or new build is constructed, dormers can come in different forms, requiring differently shaped windows.
There are shed roof dormers, for example, where the extension slopes in the same direction as the main roof but at a shallower angle. A hip dormer, on the other hand, works in a similar way but is rather characterised with a slanting roof of its own. An eyelid model, on the other hand, would feature a long curve. These types of dormers are well-suited to standard square or rectangular-shaped windows. Others, such as eyelid loft conversions then require particularly small dimensions while a flat-roof dormer could work well with a strikingly generous glazed surface. Thanks to our custom manufacturing, at Neuffer a wide range of window sizes are possible – just contact our expert teamto find out more today.
Some further types of loft extensions then also exist. These include gable-fronted dormers or bonneted models that add impressive character or may be required in certain listed areas. Due to their unique shape, these gables often require trapezoid or arched windows that can be harder to find. At Neuffer charming design has few limits though and a range of different arched, trapezoid, and triangular windows are available. Many of the shapes can also be coupled together or feature extra glazed elements like upper fanlights. This makes our products particularly versatile, ideal for fitting with an elegant, traditional style to showcasing contemporary architecture.
Key Factors to Consider when Purchasing a Dormer Window
When it comes to renovations, gaining more living space without having to move is one of the main attractions of loft conversions. From adding a home office to creating an extra bedroom for a growing family, turning an empty space into a functional room can increase property value as well as quality of life. To ensure maximum comfort though and meet planning permissions, the window should perform excellently in the following categories:
- Thermal insulation
- Noise protection
- Ventilation & weather resistance
- Design
Saving on Energy and Creating Peaceful Spaces
Given the fact that a dormer window is often located at the front of homes and may aim to make once damp, cold spaces warm, it should be produced with purpose-designed parts. As a large proportion of a window's surface area consists of glass, efforts are often focused here. At Neuffer all windows come with good quality double glazing as a standard. Featuring two panes with the space between them filled with inert argon gas, this makes for effective thermal insulation. Microscopic low-e coating made from metal oxides then also helps to reflect solar radiation. To further enhance energy efficiency though and create a comfortable year-round interior climate, triple glazing is also available. Featuring three panes, this glass is thicker and will prevent energy loss via conduction to a greater extent, helping to keep roof rooms cool during hot spells and warm when it's cold out, which in turn saves on utility bills.
Beyond glazing, the window's frame also plays a role in ensuring a steady interior temperature. Choosing one made from innovative uPVC, for example, will have the frame feature multiple built-in chambers that contain air and slow heat conduction. A warm edge spacer can then also be added to the material's core during manufacturing.
Alongside heat, because they are installed high up, dormers are also exposed to sound waves. These may be from typical nearby noises but also those from far away since the elevated position means there is less in the way to block the travelling sound. At Neuffer, glazing can therefore also be customised for soundproofing. Panes of asymmetrical thickness are used to reduce sound by up to 38 dB, for example, which has it meet noise reduction classes 2 and 3. At a maximum, this glass is recommended for a house situated around 300 m from a motorway with around 5000 vehicles passing each hour. If an invisible "silence foil" is additionally integrated during manufacturing, noise reduction classes 4 and 5 can then also be achieved, reducing sound by 45 dB to create quiet spaces even for a house located 300 m from an airport.
Ensuring Durable Weather Resistance
Given its exposed position protruding from the front of the roof, a dormer window also tends to be more exposed to the elements than a standard window installed in an average wall opening. Although vinyl frames provide superior insulation and can be particularly suitable for locations that face extreme temperatures or for damp attic roof renovations, for other properties an aluminum or externally clad frame may be a better option. For coastal areas, for example, the naturally impact resistance and robust metal could be ideal because it can withstand high pressures and strong winds very effectively. At Neuffer, aluminum window frames and composite aluminum vinyl oraluminum clad timber are then additionally anodized to make them anti-rust and particularly durable. Special coatings can then also be applied to improve anti-corrosion properties and reduce the weathering impact of salt in the air.
Customising Design & Smooth Operation
No dormer window will be ready for its purpose without a safe, user-friendly opening and tailored style. At Neuffer we therefore offer a range of different systems and finishes to achieve this. Whether formed from one or multiple sashes, the product can be fully fixed, for example, but also feature separately openable sections that can swing open or securely tilt inwards via a handle or motor. These systems have the window provide a steady, secure, and subtle supply of air to roof spaces, which helps to prevent mould and creates a comfortable climate.
Alongside user-friendly openings, at Neuffer we can also supply different shading systems. One popular option are our roller shutters that can be operated with a crank, belt, or motor, which can optionally be connected to a smart home system. The shutters add extra weather protection and keep interiors cool. They can also be coloured to match the house façade.
Beyond coloured shutters, our window frames come with a wide range of quality surface finishes. From a charming oak frame fashioning a varnish to a uPVC one coated in a durable anthracite tone, all colours are professionally applied during manufacturing.
