Smart ways to safeguard your property

Waterproofing is a means of preventing water from entering your property. Keeping a building dry, allows for reduced humidity within and is essential for retaining a building’s structural integrity and aesthetics.

It has become ever more vital to also consider the performance of a building’s thermal efficiency. Poor thermal protection of the building envelope must be addressed. That includes all areas connected to the external environment such as facades, shafts and especially roofs.

When considering different building envelope products, it’s important to understand that energy radiates from all objects. The sun radiates energy primarily on the visual spectrum and near-infrared. There are 3 methods of energy transfer that affect energy efficiency in the building envelope. These are:

• Conduction, which is countered using an insulation R-value;

• Convection, which is countered with an airtightness layer;

• Radiation, which is countered with a radiant barrier. Indeed, solar reflective white paints contain additives that generally deliver near-infrared deflection performance better than other products such as shiny metallic surfaces and Low-E films.

Solar reflective paints work by deflecting the sun’s radiant visual energy. Earth receives energy from the sun in the form of solar radiation with varying radiation wavelengths along the electromagnetic spectrum. The sun emits strongly in the visible light range, but it also produces ultraviolet and near-infrared radiation.

High solar reflective paint helps keep heat out of buildings. Should that building not have any insulation, a real solution for improving the performance of a roof includes using a solar reflective paint. High solar reflectance also improves comfort during a hot day. Indeed, they offer better durability over standard white paint and therefore add significant value to an asset.

Weber Dry Reflex-P is Saint-Gobain’s Solar Reflective Paint with a Solar Reflectance Index (SRI) that has been tested and certified according to 103, ASTM E1980-11. It also carries LEED certification since it contributes to the satisfaction of the SS Credit for the reduction of the heat island effect, according to the LEED v 4.1 Protocol.

This high-performance, single-component paint, is water based and contains special pigments and ceramic additives which confer high solar reflectance properties when applied over liquid membranes, to concrete, cement, wood and metal surfaces, and in particular over already laid carpet membranes, in so doing extend their life.

With 10,000 people in 60 countries, supported by almost 200 production units, Weber is the brand that cares about building better for people and the planet by offering proven solutions that deliver improved sustainability and high performance.
