Metal coverings on roofs and exterior walls are an old invention. You might wonder, but many historic buildings have long been using metal cladding for houses. This popularity has risen to the extent that you can now easily see steel, aluminium, or other metal cladding on many residential buildings in Australia. 

One of the most popular of all cladding types is Naistrip Cladding. Installing it over your building facades is straightforward, yet neglecting its proper installation can take away its benefits. This is why we will help you identify the common installation problems and their solutions through this blog and let the magic of Nailstrip cladding shine for a long time. Keep reading till the end for professional expert advice. 

Challenges in Nailstrip Cladding Installation and Ways to Resolve Them

Nailstrip cladding is much known for its sleek design, durability, and easy installation. However, any simple installation also demands attention to detail and expert-level knowledge. If you are experiencing problems with its installation, you are likely overlooking some of its important aspects. 

Let’s now understand the problems and solutions to overcome nail strip cladding installation challenges.

1. Metal Expansion and Contraction 

The Challenge

Thermal expansion is common with metal cladding systems, including nail strip cladding systems. Metals expand and shrink for three reasons. First, metals like steel, aluminium, or copper used in nail strip cladding are naturally reactive. Second, temperature changes cause these metals to expand and shrink. Last, leaving too little or too large a space between panels during installation also leads to buckling and loosening.

Solutions and Preventive Measures

Allowance for Movement: 

Install the cladding system to allow panels to move during weather changes. Ensure adequate gaps between panels and at junctions to allow expansion and contraction.

Use of Expansion Joints: 

Install expansion joints at regular intervals that can absorb the panels when they are moving and prevent stress on them.

Proper tools: 

Use flexible bolts, like sliding clips, that allow panels to move slightly without compromising the integrity of the installation. Avoid over tightening these tools to let the panel move freely during heavy winds.

Expert Tip: 

According to experts, using a flexible sealant in joints for metal cladding in houses can help manage thermal expansion effectively while maintaining a weather-tight seal​.

2. Metals Eventually Rust After a Few Months

The Challenge

Rust on metals is a big concern when installing nail strip metal cladding. Although this type of cladding is known for its rust-free quality, excess moisture and industrial pollution can still be enemies to its robust quality. More than that, careless handling of metal cladding should not be overlooked. 

Solutions and Preventive Measures

Material Selection: 

Choose corrosion-resistant materials like Colorbond® steel, aluminium, or stainless steel. These materials are designed to withstand harsh environmental conditions that later turn into excess rust.

Protective Coatings: 

Apply protective coatings to the metal panels. For instance, Colorbond® steel comes with a pre-applied protective layer that can reduce the presence of corrosion.

Regular Maintenance: 

To make the nail strip cladding installation effective, it is essential to clean the cladding and remove any particles, dust, and grease that can degrade the coating.

Expert Tip: 

Professionals recommend using sealants and protective tapes at joints and connections to protect the material from forming heavy rust layers.

3. Installation Errors

The Challenge

Improper installation means you are facing issues with displeasing looks and less durability and are also compromising on its effectiveness. Carelessness in installation can result from incorrect measurements, insufficient attachments, and avoiding the right sealants.

Solutions and Preventive Measures

Follow Manufacturer Guidelines: 

Always adhere to the manufacturer’s installation instructions. These guidelines are true and best written for the safety and longevity of the nail strip cladding.

Proper Training: 

If you are hiring an installer, make sure they have a complete understanding of know-how and are well experienced in installing nail strip cladding, both horizontally and vertically. 

Use of Quality Tools and Materials: 

Employ high-quality tools and materials to ensure precise installation. Cheap or inappropriate tools can lead to mistakes and damage to the panels.

Regular Inspections During Installation: 

Conduct regular inspections throughout the nail strip cladding installation process to catch and rectify errors early.

Expert Tip: 

Experts emphasise the importance of starting with a well-prepared surface. The surface should be even, clean, and properly aligned to support the cladding panels correctly​.

4. Water Leaks

The Challenge

The water inside the building coming through the gaps and lines of the weak cladding system can also occur when it is not sealed.

Solutions and Preventive Measures

Proper Sealing: 

Use high-quality sealants around joints, edges, and other gaps to create a barrier against heavy rains or slight breezes.

Overlapping Panels Correctly: 

Ensure panels are joined correctly to prevent water from seeping through gaps. The interlocking design of Nailstrip cladding helps create a secure overlap.

Adequate Flashing: 

Install flashing at critical points, such as roof-to-wall junctions, window openings, and the base of the cladding, to direct water away from the building.

Regular Inspections: 

Periodically inspect the cladding for signs of wear or damage to the seals and address the problems on the spot.

Expert Tip: 

Professionals suggest using a water-resistive barrier (WRB) behind the cladding as an additional layer of protection against water leaks and damages.

5. Aesthetic Issues

The Challenge

Achieving a flawless and modern design look with nail strip cladding can be challenging if panels are misaligned or there are visible fasteners and seams.

Solutions and Preventive Measures

Precision in Alignment: 

To make the panels look even, take extra care in aligning them during installation. Use levelling tools and alignment guides.

Concealed Fastening Design:

Utilise the interlocking design in Nailstrip cladding to hide screws and nails.

Attention to Detail: 

Pay attention to detail around corners, edges, and junctions to ensure a professional look.

Expert Tip: 

According to installers, pre-planning the layout and marking out the positioning of panels beforehand can help achieve a more precise and aesthetically pleasing finish.
