Nine benefits, Zero problems

At Nine Zero, we manufacture and supply high quality, unique traditional timber products, that we have been perfecting for more than 10 years.

timber windows and doors

1. Sustainable

As we are all very aware, now more than ever, our planet is threatened by climate change. Choosing timber products generates a lot less waste during manufacture and reduces your environmental impact on the earth. When considering the ‘whole life’ cost of timber, research has shown that timber windows are 14-25 percent cheaper than other materials, such as PVCu. Choosing timber products for your home also contributes to saving operational energy over the life of a building. Wood is also the only natural renewable mainstream building material, so if you want to do your bit for the environment with your next home improvement project, then timber windows and doors are the perfect choice.

2. 10 year warranty on paint and stains

All of our products are available in a range of finishes and colours, including any RAL colour, and now the traditional heritage Farrow and Ball range. This way, you can have full design flexibility and create a stylish suite of timber doors and windows for your project. The paint is applied under the paint manufacturer’s conditions and comes with an incredible 10-year warranty. This applies subject to the specification of the type of paint, finish and number of coats applied in the factory.

3. 30 year guarantee on timber

We have full confidence that your windows and doors will last, so there is a 30-year guarantee in place for complete peace of mind. We manufacture high quality, carefully selected timber windows and doors, which have been tried and tested to ensure a safe, high performing and quality product for many years to come.

4. 6-8 week lead times

Get started on your project in no time with our quick lead times of 6-8 weeks. We deliver nationwide, all year round and work closely with you from order confirmation to delivery, so you can have full confidence that you can get perfect timber windows and doors delivered when you need them.

5. All windows and doors are fully certified with Document Q and PAS 24

All of our timber windows and doors are fully certified to Document Q and PAS:24. Adhering to Document Q means that your windows and doors provide a certain level of security against any intruders to ensure that you feel safe and secure in your home. PAS:24 also contributes to the safety of you and your home, protecting houses and commercial buildings from the threat of opportunistic criminals.

6. Made in the UK

All our wooden windows and doors are proudly made in our Cornwall workshop by accomplished, experienced craftsmen. With meticulous attention to detail and state of the art technology, we manufacture the highest quality timber products for any project.

7. Expert specification advice

Our experienced team are on hand to provide you with all the information you need, helping you choose the right specifications for your project. From technical details to product choices, we are here to deliver solutions for any of your specific requirements, from design to delivery.

8. Naturally thermally insulating

Wood offers the most environmentally friendly insulation as it contains chemically bound water which absorbs heat energy and helps to prevent overheating in the summer. Wood fibre is also very dense, which slows the passage of heat through the material to keep homes warm in the winter and cooler in the summer.
