How To Choose The Right Type Of Windows For Your Home

Choosing the right type of window for your project can make a big difference to the comfort of your home, your energy bills and your ongoing maintenance costs. We asked the experts at VELFAC, makers of modern aluminium/wood windows, to explain the wide world of window options.

Windows today come is all shapes and sizes – and also a range of materials. Timber and PVCu are common choices, but metal frames are another option for domestic projects. There are also composite systems that use external aluminium and internal wood, a construction that already popular in roof windows such as VELUX.

To help you decide on the right windows for your project, here’s a quick guide to the different window materials currently available.

Wood

Advantages: Warm, natural wood has always been a popular choice of window frame. It adds character and style, inside and out, and has great design flexibility as wood can be painted, stained or varnished, and can be used in both traditional and contemporary projects. In terms of window performance, wood is a good insulator, and is also an environmentally friendly, renewable building material.

Disadvantages: Wood has a naturally short life cycle, and wooden window frames need regular repainting or repairs, especially in exposed locations, such as on the coast. Timber frames often feature thicker sight lines (frame width) which reduce the amount of natural light entering a room, and also reduce acoustic insulation.

PVCu

Advantages: Many homeowners replace their wooden windows with PVCu alternatives as these require far less maintenance, and offer good insulation and improved security often at an affordable price. PVCu can also be specified in a range of solid colours, not just white, and also in wood-grain effects.

Disadvantages: PVCu systems can also suffer from thick sight lines which impact on the appearance of the window, cutting down natural light and reducing acoustic insulation. White and pale coloured frames can discolour in sunlight, and although ongoing maintenance is limited, the expected lifetime of a PVCu window can be relatively short.

Metal

Advantages: Metal windows (usually aluminium or steel) are also very low maintenance and offer a long performance lifetime. Design versatility is a hallmark of metal-framed window systems, making them an option for traditional and contemporary homes, and they are also very secure.

Disadvantages: Metal frames are more commonly used in business projects, and as a result can look ‘cold and commercial’ in a domestic environment. Insulation is an issue – good performance can be achieved, but at a cost. As with wood and PVCu, sight lines can also be quite thick - slim frame options do exist, but again, they can be expensive.

Composite

Advantages: Increasingly used across the UK, composite frames combine external aluminium with inner timber to give the best of both worlds – an attractive timber internal frame protected by durable, low maintenance, sleek aluminium. This also brings great design flexibility – the opportunity to create large windows, for example, and to specify difference frame finishes inside and out. The composite design allows the construction of distinctive slim frames which maximise natural light while delivering excellent insulation, acoustic control and enhanced security. A composite window can offer an operational lifetime of up to 40 years, and both aluminium and timber are also recyclable, improving sustainability. Composite windows are not the most expensive on the market, and when energy savings are taken into account, together with minimal maintenance costs, a composite system can prove to be the most cost-effective option for many projects.

Disadvantages: We can’t think of any!

If you're considering composite windows, VELFAC gives the best of both worlds - the warmth of the timber inside and the durability of aluminium outside. Find out more about VELFAC and learn about the Price Match Challenge.
