Buildings need to be protected. And there are various ways of doing so. Generally, the right roof, cladding and waterproofing are the three main ways. Problems related to unwanted moisture are by far the most common and expensive of those encountered in building design and construction. The common avenues of water intrusion are: roof leaks, degraded sealants around windows and other penetrations, and seepage through concrete cracks. Other leak sources are not so obvious and require careful evaluation of not only the individual envelope components (e.g., roofing membrane, wall cladding, foundation waterproofing, windows) but also the interface between components and their interaction with the HVAC systems.

Terrace is the most crucial segment of a building, and it is exposed to direct climatic variations, extremes of rainfall and structural movements caused thereby. Every effort should be taken at the design stage itself to ensure that a proper protection system has been incorporated. It has often been found that the economic solution is not always the best solution. So, the system, which assures maximum protection, should be selected even though it may cost little more.

Tata BlueScope Steel, a market leader in roofs, has designed some unique roofs for establishments and individual houses. Riten Choudhury, MD, Tata BlueScope Steel, says, “One of the advantages of our steel is that it brings down the inside temperature of the room by 50 Centigrade as compared to any other steel. It is because of the superior quality of paint we use. The paint is highly expensive & patented by BlueScope Steel. We have our own design team in India who come up with different profiles which are then tested by reputed institutes like IIT Chennai, before they are offered to customers. Our ZINCALUME steel is the world’s leading Al-Zn alloy coated steel product and continues to set standards for corrosion resistance and long life.”

Today, the cladding material for the creation of façades is high on quality and safety while keeping in mind its aesthetic appeal. Conventional products that were once used as the default cladding materials – such as ACP (aluminium composite panel) – are gradually being replaced by much better alternatives like slim porcelain slabs. WPCs (wood polymer composites) are now one of the most preferred materials for exterior cladding. It is used for its almost real texture and the look and feel of wood...Yet it is more lightweight, durable with an ease of application and maintenance.

Ashwani Khanna, AVP, marketing, FunderMax India, says, “Residential building designs have evolved in the past decade. Cladding was not a common sight earlier in residential facades except for the traditional overhang-type sunshades, but now it is fairly present in most contemporary residences. Also, cladding is more common in private residences in tier 1 cities when compared to tier 2 & 3 cities. Some of the regular applications include the rear ventilated façade system, sun-shading system and extended soffits. Cladding as an application is gaining popularity in private residences due to their aesthetical and functional benefits that can be clearly seen or experienced via their commercial applications. Besides, they are also influenced by energy efficiency and operational efficiency of the buildings and adds to the occupant comfort.”

FunderMax has Max exterior panels that are safe, durable and anti-microbial high pressure laminates (HPL) which can give your buildings character. The market seeks safer materials that are fire retardant, solvent resistant, anti-graffiti, etc. They should meet the performance requirements of the building such as structural integrity, durability, weather-resistance, acoustic insulation, thermal insulation. Some of the modern alternatives are UHPC (Ultra High Performing Concrete), Carbon Fibre, Corten Steel, ETFE Membranes and Solid Surfaces, to name a few. The differentiating advantage of Max Exterior (FunderMax) are eco-friendliness, thermal efficiency, energy renewability and sustainability.

Cladding commercial buildings are a common sight. In addition, buildings that have gone through cladding don’t easily crack, especially if subjected to climate or temperature change. Kapil Chikodi, VP, business development, Glass Wall Systems, “says, “Maintenance costs of commercial buildings tend to increase with weather conditions being what they are in India. Hence, cladding is necessary. Today, more buildings are going in for cladding so as to reduce maintenance costs in the long run.”
He goes on say that the market is seeing a range of products for cladding materials.

In construction, a building or structure is waterproofed with the use of membranes to protect contents underneath or within as well as protecting structural integrity. Sanjay Bahadur, CEO – CC, Pidilite Industries, says, “We strive to come up with innovative and relevant technology and ensure that we stay true to the environment. With energy being in short supply across large parts of India, it is essential to create comprehensive solutions that are energy efficient and best suited for creating sustainable structures. Our aim to provide sustainable waterproofing and insulation solutions with zero maintenance."

Apurva Gupta, Chief Marketing Officer, Rivali Park CCI Projects, says, “For the purpose of basement-waterproofing treatment we make use of crystalline coating-maxseal super chemical while for the toilet, flower bed, balcony and terrace waterproofing we use Mastercrete 81 chemical. During the construction process we take steps to ensure that our buildings are totally water-proofed through the use of caulk and seal window. We inspect the roof and terrace, the downspouts and the sprinkler and irrigation system. Additionally, in our construction site we have installed gutter guard and our plumbing systems have an emergency pressure release value installed in them to safeguard the process of water-proofing.”

Khanna says, “Functional cladding helps in protecting the building from rain and avoids seepage of water into the building walls. When rainwater seeps in through the gaps between cladding elements, it gets easily drained from the bottom. The remaining moisture in the space between wall and cladding is quickly dried due to the constant flow of air behind. This phenomenon ensures protection of the building envelope from water.”

FunderMax Max Exterior façade system is based on the Rear-ventilated principle, which is advantageous due to its compatibility in integrating insulation and weather protection materials. During monsoons, this sustainable façade system drains the rain water away from the walls. They are hence less susceptible to damage and additionally, fire and noise protection requirements can be incorporated easily. Also, it provides lasting protection against condensation of water.

Today, developers are not turning a blind eye to keep buyers happy. Technology is ready at hand and most of them are using them to the maximum to keep residents happy and tension-free.
