When we came to name our comprehensive collection of sliding sash timber windows only one seemed appropriate, as it truly reflects the long history of our company – The 1811 Collection. The same things that Allan Bros stood for way back then, in the Georgian period, are the very same things we stand for now.
That emphasis on restoration and tradition is why we firmly believe – given the choice today – the original builders of your home would install FSC®-certified Allan Bros timber windows. Especially as the 1811 Collection has been purposefully designed with conservation concerns as a key priority.
The 1811 Collection offers a wide range of options including traditional Cords & Weights, the more modern Spiral Balance, as well as the versatile Slide and Tilt option. Every window style in the collection has been carefully designed to combine simple and timeless beauty with effortless practicality.
With an estimated lifespan of over 60 years and warranties of up to 30 years, peace of mind comes as standard.
They are available with arched frames, decoration bars, a choice of 4 horn types, as well as coming with extensive hardware options. All the timber we use is FSC® certified and the range is carbon neutral.
The standard specification is internally beaded and double glazed. It comes with a choice of bead profiles, Lambs Tongue or Ovolo, and externally can have a simulated putty profile. Ideal for a modern new build property.
For those customers who need specific conservation requirements, Allan Bros also offers an alternate specification with through bars of just 24mm and double glazing as standard. They can also be ordered as single glazed utilising a special putty option, which adds an extra aesthetic authenticity.
Featuring a lead weight pulley system or our easy spiral balance slide system, the comprehensive range of beautifully engineered, stylish sliding sash windows bring a level of aesthetic elegance to any property.
Perfect for replacement renovations and new builds alike, our Slide and Tilt Sash window combines classical elegance with modern practicality and operates like a traditional sash but with the benefit of tilting inwards for safe cleaning and maintenance.
If you’ve got a modern home that may not accommodate the traditional timber sash window fittings then don’t worry, that’s where our spring system comes in. Using pre-tensioned springs instead of the traditional wheel and pulley system you can enjoy the style and appeal of traditional wooden windows.
These are our standard colours, however we can provide your windows and doors in any RAL colour. There is also a range of woodstains available. More information available on these woodstains on request.
Our team of experts are here to take away all the hassle. We can help you find the perfect window solution, advising on style and finish and taking care of everything from measuring up to installation.
After more than 200 years of hand crafting the finest timber windows and doors, you can expect us to be more experienced than most. You can also expect us to have learnt a thing or two about what our clients want, need and demand – and we have. That’s why we offer an unrivalled support service backed up by industry leading warranties and guarantees.
