Application of an energy-efficient roof coating

Even our little country is subject to intense temperatures now and then. In summer, air conditioning units often work overtime to keep the indoor temperature tolerable. A reflective energy coating on your roof (and façade) will reduce your dependency on cooling systems. This will result in a more pleasant indoor climate and allow you to save significantly on energy costs.

Reflective energy coatings are environmentally friendly and resistant to heat, frost, dirt, moss, etc. Generally, reflective coatings are applied in combination with a waterproof, high-build coating that serves as a substrate. Depending on the roof slope and type, cutouts and the existing insulation, this solution may achieve heat reductions of 5-8 degrees.

The coating limits the rise in temperature, which means your cooling system won't use as much power. On top of that, it will add an extra sense of comfort to the space, as it will reduce the forces and tensions in steel roofs and façades. As a result, there will be less creaking and movement, which is a pro for both the employees and the building itself.

My door or frame is damaged or dented. Can this be repaired invisibly?

In many cases, the damage can simply be fixed virtually invisibly. However, this does depend on local circumstances, the condition of the substrate and prior maintenance. Every day, our experts successfully perform work on both new buildings and buildings that are 30-40 years old, so there is plenty we can do.

What products do you use? Are they the same as those on the original?

For example, 9 out of 10 times, overhead doors feature a coil coating, which is also known as pre-painted steel or aluminium. This could be a colorcoat prisma, PVDF, silicon polyester, or an HPS Plastisol coating, among others. Coil coating is a factory process involving extreme heat. As such, it cannot be applied for repairs. Frames, façades and wicket doors often feature a powder coating. This is an electrostatic process combined with temperature, i.e. a factory process taking place under constant and controlled conditions.

Whatever the method, these are all excellent substrates for our paint systems. The products we use are derived from the automotive sector and were specifically designed for repairs to sandwich panels and profiles. The paints seamlessly fit the applied coil coat when it comes to durability and appearance. We are familiar with all types of coating systems and always have the most common colours in stock.

What is the deal with colour differences?

No two colours or buildings are the same. Even if they have the same RAL code or name, every new coil will have a different colour or appearance. This is because most pigments for paints and lacquers are derived from nature, so their properties may differ from shipment to shipment. This phenomenon has an extra dimension in case of metallics, which professionals call “flop”. This refers to the way metallic particles are positioned on the surface, which can result in a darker/lighter effect. You can compare this to a high-pile carpet. The colour doesn't change, but if you run your hand over it, you will get lighter and darker areas.

Buildings and panels suffer from discolouration over the years. One of our specialisations is “retinting”. This means we use the right pigments to touch up the damage so it matches the existing colour.

Van Heemskerk is an expert in mixing the most suitable colour during repairs. We strive for customer satisfaction by making our repairs “virtually invisible.”

We operate both within the Netherlands and abroad. Every day, we perform our activities throughout the Netherlands, Belgium and Germany. We also have projects far beyond this scope, such as in North and South America and the Middle East.

Whom do you work for?

We work for well-known panel manufacturers, property owners or tenants, property managers, installation companies, construction companies and private individuals.

Do you also repair other materials?

Yes, our service covers a wide range of applications, including repairs to sandwich panels and sheeting. Please refer to the other parts of this website for more information. We also work with composite and wooden constructions. We can usually offer a solution, even if this is not necessarily listed on our website.
