Omega (Roofing) Plastics Ltd

Specialists in Polycarbonate Roofing and Sheets

Omega (roofing) Plastics Ltd manufacture and supply Polycarbonate Roofing, Polycarbonate Sheets and a wide range of components and services to the conservatory and lightweight roofing market. We are able to offer professional advice, based on over 15 years experience from our dedicated staff in helping our customers select the most suitable solution for their roofing requirements. The professional advice includes the design and supply of bespoke conservatory roofs.

Polycarbonate Roofing

We manufacture and supply structured polycarbonate (SPC) panel roof-packs, cut-to-size to both trade and DIY customers. The projects we are involved with range from the relatively simple lean-to roofs, through the huge variety of domestic conservatory designs to large commercial roofing solutions for supermarkets, warehousing, large public projects.

We supply all polycarbonate roofing components from stock to anywhere in the UK. We supply a variety of glazing bars and accessories. These include rafter-supported bars (suitable for timber supported roofs), self-supporting bars, wall plates, eaves beams, hip rafter bars, ridge beams, finials. We also supply roof vents suitable for all installations with either glass or Polycarbonate glazing.

Our range of accessories include all the components required to complete a roof installation. These accessories are Sheet Closure Extrusions (used to protect and finish the bottom edge of the polycarbonate panel), Eaves Filler (to close gaps at the Eaves and prevent draughts), Screw Buttons, Solid Aluminium Top Tape and Breather Anti-Dust Tape to seal the ends of the polycarbonate roof sheets, Silicone Sealant and Self Adhesive Flashing

Polycarbonate Sheets

Our polycarbonate sheets are supplied in a wide variety of colours and thicknesses. The colour range is clear, bronze opal, bronze-opal and heatguard-opal. Heatguard-opal is designed to control the heat build-up in conservatories and is effective in reducing the impact of the suns’ energy by 50%. We are also able to offer solar inserts as a factory fit option fitted to the polycarbonate sheets. These are the most effective solution in controlling heat build-up in conservatories. The solar inserts reflect 80% of the suns’ radiant heat and reduce glare by 80%. Solar inserts can also be fitted by Omega fitters to existing polycarbonate roofs through our Omega Solar Insert Retrofit Service and, in addition, solar inserts are supplied as a solar insert DIY kit.

The polycarbonate Sheets vary in thickness from 10mm, through 16mm, 25mm, 32mm to 35mm. The thicker polycarbonate panels offer the highest level of insulation of any glazed roofing solution. The 35mm polycarbonate has a U-value of 1.2.

A similar solution is provided as a supply and fit service for glass roofs, employing a solar film with similar specifications to the solar inserts.

In order to provide a comprehensive range of roofing solutions we also supply and fit a number of different types of canopy. These canopies can be Cantilever or Self-supporting. The cantilever options are suitable for a wide range of applications. Their key attribute is that no supporting posts are required and therefore provides an uninterrupted floor area. These are particularly popular as car ports. The Post-Supported Canopies are very flexible as they can be configured to fit most customer specifications for an outside covered area. Both types of canopy can be used as Smoking Shelters. We do supply specialist standalone Smoking Shelters in addition to the canopies.

The secondary glazing can be supplied with different thicknesses of glazing material to suit the installation and also in either acrylic sheet or plate polycarbonate sheet. Plate polycarbonate is specified where security/safety is a key customer requirement, being 250 times as strong as glass. All secondary glazing can be cut-to-size in our factory.

The tubular roof lights are supplied in both rigid and flexible variants. The flexible roof light is very popular as it is very easy to install.

C Allen,

I just wanted to let you know how pleased I am with my canopy. My husband erected it in 2 days without too many hitches and it looks stunning with the clear roof panels. Congratulations on such an efficient, friendly and helpful team.

Hi. This is the omega canopy that I purchased from you. I fitted on my own in a couple of hours. Instructions were detailed, it was well packaged, and was exactly as I expected based on the description on your website. Obviously I have modified it a little. Thanks

Mr Iliffe,

We would be delighted to recommend Omega and their wall mounted lean-to Smart Canopy product. From our very first enquiry they were helpful and informative and a pleasure to deal with throughout the purchasing process. Delivery arrangements were mostly excellent and although one problem was encountered which was beyond their control it was quickly and cheerfully rectified. Installation is simple for anyone with basic DIY skills provided you follow the comprehensive instructions (which are provided) carefully. The product itself is very good quality, strong, looks good and professionally made. If you are considered glass vs the glass clear plate polycarbonate we would definitely recommend the polycarbonate as it is much lighter to handle and therefore easier to install than glass would be but looks just as good as glass with the benefit that it won’t shatter if something falls onto it. Overall we are very pleased with our canopy and can now plan barbeques without worrying about the weather.
