Sandwich Panels
Did you know all your glass can be replaced with sandwich panels? The roof, sides, and gables of any commercial glasshouse structure can be swapped out for this innovative solution to help you create a well-insulated professional space that looks as good as new.
Whether you’re constructing an entirely new commercial or industrial space or would like to re-purpose and transform an existing glasshouse into one, a sandwich panel system provides the ideal solution for creating professional-looking insulated spaces you can depend on.
We are experts when it comes to helping growers and garden centre professionals re-purpose their glasshouses with a sandwich panel installation. You can choose to remove all the glass, some of the glass, or choose the half-and-half option for your roof, sides, and gables.
Replacing your glass with sandwich panels delivers the perfect no-waste solution. It is cost-effective, as your initial investment of your glasshouse structure gets reused. It has a positive impact on sustainability, as sandwich panels are made from 100% recyclable materials. And the best thing about them is that they’re an extremely energy-efficient solution, providing unrivalled levels of insulation which ensures you don’t lose heat whilst keeping the water out of your structure.
Sandwich panel insulation guarantees you will have a nice cool and comfortable environment in the summer, and a cosy and warm indoor temperature in the winter.
We only use the best materials from our partner in sandwich panels, WNL Horti Insulation, to create 100% leak-proof professional spaces. From storage areas to garden centres to office spaces, sandwich panels will transform any space into a stylish and comfortable environment.
What Makes a WNL Sandwich Panel Roof Systems 100% Leak-Proof?
Unlike other sandwich panel solutions, WNL Sandwich Panel Roof Systems have separated gutter profiles.
This means that your roof panels sit above your original glasshouse gutters and surpass them on the way to your downpipes. This solution ensures water collects on your roof and runs off straight into your drainage system, leaving the gutter free from water.
The combination of separated gutter profiles and the materials that make up the sandwich panels keeps the heat in and the cold out, ensuring any condensation in your existing gutters is minimal, and water cannot make its way inside your structure.
The most popular sandwich panel solution is the Build Up Sandwich System, which can be applied to both steel and aluminium gutters.

We Lead by Example
The warehouses in our own yard are all sandwich panel constructs because it provides the best insulation for comfortable working temperatures all-year-round and keeps our stock safe from water damage in rainy UK with the 100% leak-proof roof.
Our Dutch Barn (pictured) is the latest addition to our yard, fitted with 60 mm Goosewing Grey roof panels alternating with light sheets, and Sapphire Blue flashings to give it that GVZ finish.
As the Dutch Barn houses our steel, it’s important we keep the weather out to keep everything rust-free. The light sheets make for a lovely lighting effect, especially on a sunny day, which brings a pleasant atmosphere into the space.
Our glass shed has a similar sandwich panel roof, but our main warehouse is constructed using the full assortment of sandwich panel solutions with a sandwich panel roof, sidewalls, and interior space created using sandwich wall panels.
