Let’s talk about GRP
We often get asked why we use Glass Reinforced Plastic (GRP) products and what’s so special about them. So we thought it would be helpful to explain.
GRP, also known as fibreglass, is polyester resin and chopped strands of glass fibres, which are mixed together to form a flexible fabric. GRP is a moulded product, meaning it must be placed in or around the shape of the item it is required to take.
GRP fibreglass has been around since the 1950s, but new production methods mean it has now been developed into a state of the art and superior material. It’s very strong and long lasting, but also light, flexible, fully reinforced, waterproof and capable of being moulded to any shape.
How do we use it?
We use it in two ways: for our flat roofing materials and as our GRP rafter replacement roof system.
Our GRP rafters are strong, impact resistant and because GRP is so light and adaptable, we can use them in nearly any conservatory. The GRP rafters are a higher tensile strength than steel and don’t have any of the issues that aluminium or wood products can have such as condensation, thermal bridging or moisture absorption. They are also very easy and safe to install as well as being a very cost-effective option that are highly suitable for our thermally efficient systems.

GRP flat roofing
GRP fibreglass roofing on a flat roof comes with may advantages:
- Durability and Strength. Fibreglass roofs can last up to 20 years.
- Whatever size or shape your conservatory flat roof, we can cut the fibreglass to fit.
- Waterproof and weather resistant.
- Low maintenance and easy to repair.
- Ease of installation. Easy to install without the need for heat equipment.
Evolving and innovating
Conservatories are in an industry which is ever evolving and developing more efficient materials. Part of our role is to keep a careful eye on these developments so that we can be sure that our products and systems are made up of the most effective, environmentally friendly but cost-effective materials. We’re always looking for new ways to improve what we do, and we believe in being really transparent about the resources we use.

We may be bias, but we honestly believe that a conservatory can be a great place for celebrating Christmas, whether that’s by setting up a table and inviting family members for Christmas lunch or by gathering round a tree to open your presents.
It’s still only November but excitement about Christmas is building, probably because Covid meant that last year, well, Christmas was a bit of a damp squid for a lot of people.
To complete the Leka suite of products, the Leka Xi can provide a warm, sustainable alternative to a traditional block/brick built conservatory base/wall.
The last few years have been extraordinary for so many reasons, not least because of Brexit, Covid and climate change. Of course, we’ve all been affected by these massive events and in our world of conservatories, we’ve really noticed the effects of climate change recently. And if you’re having trouble with cracked, broken or damaged glass in your conservatory, it may be that you have too.
If you’re thinking of refurbishing your conservatory, one of the questions you may have are whether you can tile the roof and if so, whether it’s advisable to do so? So we thought it might be helpful to run through some of the main points to consider:
Lean to conservatories come in all shapes and sizes and the best description of a lean to is a type of simple structure originally added to an existing building with the rafters “leaning” against another wall. Some of the older lean to structures sometimes get bad press as being a bit dated and shabby, but actually, there’s lots you can do to breathe new life into your lean to.
