What is a GRP garage door?

CDC - GRP - Chertsey

If you’re in the market for a new garage door, you may come across the term GRP. GRP stands for glass reinforced plastic, a material that is quickly gaining popularity for use in garage doors for a host of reasons. Here’s a helpful guide to GRP doors, from their benefits to the styles available and what you should consider when choosing one.

What is GRP?

GRP is a composite material made of polyester resin reinforced with glass fibres. The resulting material is incredibly strong, but lighter weight than many other garage door materials. GRP garage doors are highly impact resistant and durable, able to withstand dings, dents and general wear and tear far better than wood. They also won’t rot, rust or corrode over time like some other materials either.

The waterproof nature of GRP means your door won’t absorb moisture, which prevents warping and swelling, and the material is also resistant to UV rays meaning it won’t fade or discolour over time. In fact, one of the biggest advantages of GRP garage doors is that they’re low maintenance. They don’t require painting or staining every few years, and require nothing more than an occasional wash with soap and water to keep them in pristine condition.

Security and Efficiency

Due to their insulating properties, GRP doors are great for extremely cold and hot climates. The materials prevent heat or cold transfer far better than a wooden or metal door, which helps regulate garage temperature in places with extreme winters or hotter summers.

GRP is also a great option if security is a concern – fibreglass doors are highly impact-resistant, and paired with a secure style such as an automatic opener, it’s the perfect way to keep your home and belongings safe from intruders. When well maintained, a GRP garage door can last anywhere up to 30 years, providing great value for money and peace of mind for years to come.

GRP garage doors are an attractive choice for homeowners seeking a reliable and long-lasting solution that combines functionality with aesthetic appeal. Whether facing harsh weather conditions or simply wanting a unique look, GRP garage doors stand out as a resilient and versatile option.

Customising a GRP Garage Door

GRP allows for versatile design possibilities, enabling homeowners to customise their garage doors to match the architectural style of their homes. With various textured finishes and colours to choose from, you can enhance kerb appeal and personalise your home’s exterior with ease.

You can choose from any RAL colour for a customised door or even choose a wood-effect finish to replicate the beauty of natural wood while still enjoying the benefits that GRP offers. GRP garage door prices range depending on the size you choose, the style of door and any customisation features you opt for. For a tailored quote, get in touch with our team today.

Types of GRP Garage Door

GRP doors come in various styles. For example, you may choose from our range of GRP up and over garage doors which come in a variety of finishes. Up and over doors are very secure, easy to install and maintain, and they’re perfect for smaller garages as they require less ceiling clearance compared to sectional doors.

Alternatively, GRP side hinged garage doors are great if you have a larger driveway or want to maximise interior space in your garage. A sectional door is ideal for achieving a modern look and delivers exceptional weatherproofing and insulation, keeping the interior of your garage warm and dry throughout the winter months. Lastly, roller garage doors provide smooth, quiet operation and are well-suited to shorter driveways thanks to their compact, space-saving design.

Our doors can be operated manually or automatically, depending on your preference or the level of convenience you’re looking for – you may choose to automate a larger, heavier door or if you primarily use your garage for storing a vehicle, for example.

I have dealt with Alan and CDC on several projects through my workplace, our clients and I have always been very pleased with their service so I decided to use them on my own property. Over the moon with my new sectional door, looks stunning and the fitting team were very friendly, polite and carried the work to a high standard. Would definitely recommend and will continue to use one work projects. Thanks Alan, Colin and the team! Anna

Great company! Timely, helpful and very efficient. Timea in the office was great and Ian the fitter was really good even helped out with another snag not on the job list! Would definitely recommend.

When Colin came to run us through all the options he was very knowledgeable, explained everything and was very patient with my many questions. After confirming and paying the deposit, the door was manufactured very quickly and installed within 3 weeks. The door itself is high quality, installation is exactly as agreed and the installers left the place spotless.

I contacted Simon Wallace from CDC Garage Doors a year ago with a tentative enquiry for a single white roller shutter to replace my old up and over manual door. He was very responsive and helpful at the time but I didn't go ahead as I thought we could make do with the manual garage door. Then a month ago my wife's new car was vandalised so I decided to clear the garage so that she could park it safely indoors. I reached back out to Simon who was more than happy to help. He offered a great price and visited site to measure up within a week. I paid the deposit and the fitters came a few weeks later once the door had been delivered. Peter and Mason did a wonderful job of the installation, the service was excellent and the finish was immaculate. Timea in the accounts department has been very helpful with the invoicing and logistics too. I'd recommend this company to all my friends, family and clients and wish I had pushed the button (no pun intended) sooner. Look no further than CDC Garage Doors.

CDC Garage Doors have supplied and installed garage doors for me on a number of projects. In my opinion, they supply the best products available and employ fitters with a wealth of experience. Prior to placing an order, they offer sound advice which is always appreciated. I will be in touch with CDC on our next project and would not hesitate to recommend them to others.

Excellent service. Straightforward and sensible advice given pre-fit, and then double garage door fitted very neatly with no fuss in a single afternoon, with old door removed and site left spotlessly clean. Also great aftersales and refund when I decided threshold strip not required. Would definitely recommend for workmanship from good local firm.
