We provide a variety of different plywood types for a range of applications which we can cut to any size or shape on our CNC router for a greater level of precision and reliability. Whatever shape you have in mind, we can cut it – all you need to do is send us your drawings, in either CAD format or a sketch, and we can make it a reality. Along with our ability to cut any shape or curve, our CNC router can be used for rebating, pocketing and hole cutting on virtually any sheet material. We also have the capability to carry out laser cutting, CNC engraving services for greater versatility and creative options. 

Using state-of-the-art UV printers, we are able to print full sheets of plywood in one go, providing a consistent finish at a much faster turnaround time than painting. We currently only list 8x4 sheets (2440x1220mm) but we’re able to purchase and cut sheets of up to 2000x3000mm, so get in touch with our team today to discuss your specific requirements. With optional next day delivery, your products can be with you quickly and for bigger orders, we can deliver throughout most of the UK using our own transport service. If you have a larger ongoing project taking place, please contact us to discuss bulk discounts and regular supply orders. 

A tough and hard-wearing material that can be used in external applications, marine plywood is designed to perform for long periods in humid or wet conditions. 9mm marine plywood can be used for a wide variety of applications, from walls and roofing to storage boxes and indoor vehicle buildings. This plywood resists fungal attacks and delamination so it’s ideal for using in climates and environments that are prone to moisture. We can provide 9mm marine plywood in any size or shape you require, and we offer quick delivery so you can use your products as soon as possible.


9mm Marine Plywood Grades

Wood comes in a variety of grades; we offer the grades listed below. For more information on the grades available, see our plywood grading guide.

Marine plywood is for use in environments where the wood is exposed to moisture for extended periods. The type of wood we offer has a high-quality BB/BB face grade and is well-suited to demanding environments such as gardens, bathrooms and parks as well as for roof supports and advertising panels where it needs to withstand harsh elements. 


Advantages of 9mm Marine Plywood

A big benefit of using marine plywood sheets is that it’s easy to machine and work with, as it has a great strength to weight ratio. It can be cut to size easily with just a handsaw or an electric saw, so it’s great for DIY projects. This wood can also be varnished or painted easily as it has a great surface that’s smooth and free from knots. Most woods don’t cope well with water or moisture, which can lead to rotting and warping, and a lower integrity of the structure. By using marine plywood, you can ensure that the application will remain strong and sturdy for a long period of time.

The versatility of marine-grade plywood is a huge advantage of this material. It can be used for such a wide variety of projects, from garages and sheds as a construction material to walkways where it’s expected that the wood will come into contact with moisture. Marine plywood is also a pliable wood that can be bent into shape without it losing its structural integrity, which provides an added layer of versatility. This wood provides excellent value for money without compromising on the quality. It’s resistant to cracking, warping and twisting, and also minimises splitting when screws or nails are used. Our other most popular sizes are 12mm marine plywood and 18mm marine plywood.


Applications of 9mm Marine Plywood Sheets

9mm marine plywood is a great option for using in joinery in areas where moisture is common. The thinner variety of marine plywood is ideally suited to van or trailer linings as well as for cold storage containers, packing cases or for boxing in pipes and wiring. It can be used to great effect in temporary structures or for concrete frameworks. Marine plywood can be used for signage as well, as it can be painted or stained well and can cope with outdoor environments as well as indoor signs, whether it’s for door signs, branding or directional signage. We also offer birch plywood, hardwood plywood and softwood plywood.

Frequently Asked Questions


What tolerance do you cut to?

We cut to a tolerance of +/-3mm.

What is your delivery timescale?

3-7 working days.

Is mirrored acrylic like normal mirror?

Mirrored acrylic is a flexible material, and needs to be attached to a perfectly flat surface. We recommend attaching it to MDF or something similar, making sure the adhesive is spread in a thin even layer across the acrylic. we also recommend using the 5mm thick acrylic as it is more rigid.

Can you cut any shape?

Yes, in acrylic. We will shortly be able to also cut any shape in polycarbonate as well.

What's your standard radius corner?

20mm, but we can cut to your requirements.

How many holes do I need in my acrylic?

1 per corner should be sufficient for smaller pieces. You might want to consider an extra hole in the middle if your sheet is larger.

Can I cut acrylic?

Yes, you can. Just take it slow and easy.

Can I put acrylic behind a hob?

Not if it is gas or electric. You need a gap of 5cm between an induction hob and the acrylic.

Do you fit the acrylic?

No, we don't. We do provide some templates which should help you to take your measurements. The acrylic is easy to install by any competent DIYer.

What's the difference between acrylic and Perspex?

Perspex is a brand name. It is the same as acrylic.

What's the difference between acrylic and polycarbonate?

Rated 4.7/5 on Feefo

I had no trouble placing the order it arrived sooner that expected and it was well wrapped to avoid any damage
Good value.Came securely packaged,and promptly.
I have been really happy with both products I have received from Cut My Glass. The service is brilliant and both were delivered quickly. I will definitely be using the company again.
There was a lot of questions and time wasted at the start which seemed to go on for ages. Once we had paid our money they did seem to get a move on, it was well packaged and arrived undamaged. Although there were the occasional scratch mark, so in the end we re-used 2 of our old curved windows as we thought they were in better condition.
