Polyester, Plastisol and Anti-Condensation Coatings: What’s the difference?

Here at eRoofs we currently stock a variety of coatings for our roofing sheets, including Polyester, Plastisol, and Anti-Condensation. But, what’s the difference? Let’s find out…

Polyester
High Tensile Polyester felt is a strong, durable and economical method of waterproofing flat and shallow pitched roofing. It consists of a three layer built up system, including a top layer of green or brown mineral coloured felt and has a life expectancy of around twenty years.

Polyester sheets are made with TATA steel and are ideal for a variety of applications from the construction of basic storage or utility shelters through to bespoke commercial buildings or warehouses. High-quality manufacturing and a broad range of sheet sizes ensure great value for money and long-life in demanding seasonal environments.

The steel substrate has a hot dipped galvanised coating of 275g per square metre and is primed and coated with 25 microns of high quality Polyester enamel paint. The reverse/internal surface is galvanised and coated with an alkali grey wash coat which ensures its longevity of life and has a moderate resistance to scratching.

Our Polyester sheets start at just £21.15 each and are available in Goosewing Grey, Juniper Green, Slate Blue and Vandyke Brown.

Plastisol
Plastisol sheets are designed to have a tough coating, giving the TATA steel sheets a high degree of protection against corrosion. They can be used for various applications, from garage roofs, industrial buildings and garden sheds.

The Plastisol applied to the sheets consists of Polyvinyl Chloride based Thermoplastic Resins with short molecular chains which gives the sheets excellent resistance to UV. To produce high-quality pre-coated roof sheets, a system of multi-layer coatings is applied to zinc coated high tensile steel strips and then oven cured to ensure maximum adhesion. This then provides the sheet with a high corrosion resistance and climatic protection as well as being resistant to abrasion.

With Plastisol sheets, it is imperative that you double check your measurements as we cut them to your requirements.

Our Plastisol Sheets start at £40.50 each and are available in Merlin Grey, Goosewing Grey, Olive Green and Vandyke Brown.

Anti-Condensation
This roofing coating is manufactured by bonding a non-woven polyester membrane to the reverse side of the sheet. The membrane then works by absorbing the formed droplets and retains them until the temperature rises, leaving the moisture to then dissipate naturally. These sheets also have improved noise reduction from rainfall due to their cushioning effect.

Benefits of Anti-Condensation coated roof sheets are that they are easy to clean, by simply using a hose or pressure washer, their durability compared to non-coated sheets and the fact that in the long run due to these other benefits they are more cost-effective as you will not have to continuously replace them.

As with Plastisol sheets, we do recommend that you carefully check your measurements as the sheets are cut to your specifications.

anticon merlin

Our Anti-Condensation Sheets start at £46.02 each and are available in Goosewing Grey, Merlin Grey, Olive Green and Vandyke Brown.

To keep your Polyester, Plastisol or Anti-Condensation coated roofing sheets secure and watertight, we recommend using Tech Bolts, which are ideal for fastening steel sheets down to timber and steel. These stainless bolts are excellent quality and are supplied with a hexagon head which enables fast and reliable installation time after time for exterior construction.

To give your roof the full finish it deserves, be sure to add our Tech Bolt Caps, which conceal the Tech Bolt heads. They are available in matching colours of Goosewing Grey, Juniper Green and Vandyke Brown and ensure a fabulous, professional finish.

Polycarbonate Roofing Sheets: A Few Helpful Tips

Polycarbonate is a high performance material which is perfectly suited for roofing. Polycarbonate roofing sheets have been designed for both domestic and commercial use and there are glazing systems which support polycarbonate sheets, making for a strong, yet light, shatterproof system which has UV protection built in and transmits up to 90% of available light. It is also quicker and easier to fit than traditional glazing and offers a longer lasting finish than corrugated sheets.

When choosing polycarbonate roofing sheets, it is important to make careful measurements and get the correct size because the sheets need to fit between your roof joists, however, our helpful eRoofs Sales Team can assist to ensure you get the measurements you require. You can either opt for polycarbonate sheets suitable for roofing and cut them, or buy them at the sizes you need, already cut. Additionally, polycarbonate sheets can be cut to any shape or size making it suitable for all kinds of roofs, including gable end roofs, lean-to roofs, Edwardian and Georgian roofs as well as canopies.

There is also a range of thicknesses when choosing your polycarbonate sheets suiting different purposes. We recommend the following guidelines;

Clear polycarbonate roofing sheets are a versatile option, not only because they are extremely durable, but they also have a modern and sophisticated appearance. They also offer UV blockage, even if they let light in, and because of this, they won’t discolour and will keep their smart appearance for many years to come. It is also worth mentioning that clear polycarbonate roofing sheets are lightweight, making them super easy to work with.

If you are thinking of choosing polycarbonate roofing sheets for your property, here are some helpful hints and tips we think you will find useful.

  • Polycarbonate roofing sheets are only UV protected on one side, therefore prior to installation, ensure you are clear are which side has the UV protection.
  • If you are re-using polycarbonate roofing sheets, and are purchasing more, make sure you check the exact colour to avoid any mismatches.
  • Sealing is very rarely required when installing this kind of roof sheet, so if you are using a sealant, check with the manufacturer to ensure the one you are using is compatible with the sheets.
  • When cutting the sheets, avoid using high-speed cut-off wheels as these can melt the sheets, and instead use sharp scissors or a power saw fitted with fine-toothed blades.
  • It is perfectly normal to see condensation during cooler months, but this can be rectified by modifying your ventilation system.
  • If you find debris and dirt on your sheets over time, the best way to remove this is by using soapy water and a soft brush. Avoid using any abrasive tools or chemicals as they may damage the sheets.

We also offer Polycarbonate accessory essentials to go with your Roofing Sheets, such as Glazing Bars, which are available in white or brown. These Glazing Bars are suitable for Conservatory Roofs, Carports, Gazebos and more, and are super easy to fit, securing a roof sheet on each side.

For roof edges with a sheet on only one side, the gap on the bar’s outer edge must be fitted with a Side Flashing, which again comes in brown or white. Side Flashings act as a drip into the gutter and give a lovely, sealed finish to your roofing sheets.

We also sell Corotherm Anti-Dust Breather Tape, which is a self-adhesive tape for sealing and protecting polycarbonate roof sheets to prevent build-up of moisture while keeping dirt, debris and insects out.

To protect the Breather Tape, you can then use End Closures which allow ventilation of the sheets. End Closures are safe, easy to fit, are UV-resistant and offer good weathering properties.

Another options are the Polycarbonate Super Fixing Buttons, which allows you to secure polycarbonate sheets to timber rafters to reduce the risk of the sheets becoming dislodged in windy conditions. They also come with a rubber compression gasket to stop water ingress and allow a natural expansion and contraction of the sheets.

Bitumen Roofing Sheets: Taking a Look at Their Benefits

With Winter just around the corner, it is important to ensure your roofing is safe and secure. One of our most popular roofing products are Bitumen sheets, which are a great long-lasting roofing option and can be modified to suit your needs.

Modified bitumen is a type of asphalt product which can be fitted on to the roof in a variety of ways, in both hot and cold temperatures. They are seen as the modern-day alternative to the built-up roof and today we will be taking a look at advantages of Bitumen Roofing Sheets.

As mentioned, there are several advantages to using Bitumen Roofing Sheets on your home or building and unlike more recent types of roofing, it already has a proven track record of being reliable and sturdy and Bitumen Roofing Sheets are known to last 20 years or longer.

Durability – Bitumen Roofing Sheets have a high-tensile strength, making them unlikely to develop cracks which may often appear in other flat and membrane roofs. Bitumen Roofing Sheets are also a good protectant against elements such as wind, fire and hail and are therefore unlikely to be damaged in the event of a storm and such like.

With all things in life, there are of course some drawbacks to Bitumen Roofing Sheets, however it is all about finding the product that best suits your needs. Black Bitumen Roofing Sheets do tend to absorb rather than reflect heat, and even though the roofing sheets themselves may not be heat or UV Ray damaged, if proper insulation is not used with it, the heat absorption can lead to overheating the building of which it is protecting.

The cost of Bitumen Roofing Sheets can be quite costly, however eDecks keep very competitive prices and will help you to conclude the amount of sheets and accessories you will need. You may also need to purchase granules which help protect the roof from the sun, and without including them as part of the installation process, the roof can become damaged, or again the building may overheat.

Bitumen Roofing Sheets are one of the most durable and secure roofing options available when applied and installed correctly. They may be quite costly to begin with, but will far outlast a competitive product and will keep your building safe and protected.

Galvanised Roofing Sheets: An Introduction

galvanised 1

Galvanised roofing sheets are a simple and speedy fix, offering enough flexibility to cover projects of all levels, such as a DIY project to a much larger commercial job. They have the capacity to cover large areas dependent on the size selected and are often chosen due to their protective attributes and lightweight properties. From a cosmetic point of view, galvanised roofing sheets offer something more traditional and are considered to be very cost effective.

A galvanised roofing sheet is steel that has been formed into a flat panel of sheet and is commonly referred to as steel sheet metal, which has undergone the galvanisation process in order to prevent corrosion. The galvanisation process is completed by the steel sheet undergoing a chemical process which increases resistance to corroding over the years. This process also makes the steel much stronger and more dependable.

Key Benefits:

  • Even in rural and harsh conditions, galvanised roofing sheets have a life expectancy which is much longer than sheets which have not been treated for protection against corrosion. This makes it a better option because it reduces how often the materials will need to be replaced.
  • Galvanised roofing sheets are a sustainable and recyclable product and because it has been treated with a zinc coating, galvanised roofing sheets will last longer, ensuring a lower impact on the environment. The material can also be reused if its properties have not had too much use over time.
  • Reliability is a key benefit when it comes to galvanised roofing sheets, and how the product will react throughout its lifespan is easily predicted and presents very few products over time. Galvanised roofing sheets are also renowned for their strength as it can hold its weight when implanted in structural applications.
  • Another advantage of galvanised roofing sheets is that due to the longevity of them, they are almost always the most cost-effective material. More often than not, galvanised steel is cheaper upfront than other methods of treatment and even if the initial cost is more, the long-term costs will be much lower because of how long they last and how little maintenance they require.

To ensure your galvanised roofing sheets are securely fastened down, we highly recommend Spring Head Nails, which are the perfect fit with an extra-large head to distribute the load directly underneath the top of the nail. Spring Head Nails have a twisted shank for increased holding power and absorb movement when expanding and contracting in varying climates and ensure your roofing stays firm and secure and come complete with PVC dowty washers.

There are two types of galvanised roofing sheets, and starting with Box Profile Sheets, these are economic sheets in a robust, rigid profile design that offer high strength and are available in multiple lengths. Box Profile Sheets are suitable for industrial, agricultural, commercial and domestic roofing and cladding, and can be used as single skin sheeting, over clad of an existing roof or part of a built-up insulated area. They are lightweight, fast and easy to fit, and are the perfect product to be used on walls and roofs. Box Profile Sheets are made using seven rigid profiles of 166mm pitch across the sheet width and 34mm profile height ensuring maximum strength. You will find that they have a wider coated steel strip which gives a secure weatherproof lap, and are a modern alternative to traditional, corrugated roof sheets, often being favoured for domestic properties.

Whereas Corrugated Roof Sheets give a more traditional look compared to Box Profile Sheets and have been around for many, many years. Their popularity often occurs due to their ability to be cut to length, making them a quick and easy roofing solution. Corrugated Roofing Sheets are available in a variety of colours and finishes enabling you to personalise your roofing, whether it be in a domestic, industrial or agricultural setting.

Here at eDecks we have a broad range of sheet sizes which have been manufactured to a very high standard which gives you, the customer, great value for money and longevity in demanding seasonal environments. Be sure to check out our Galvanised Roofing Sheets here.
