Swartland, a supplier to the building industry, will soon launch its Summit XPS Insulation Board as part of its Summit range of insulation and ceiling products. Daneel Pretorius, category manager for the product range, says extruded polystyrene (XPS) is environmentally-friendly, lightweight, easy to install and energy efficient.
“It is also affordable, 100% locally made and manufactured in the Swartland factory, following strict global warming potential protocol to ensure a zero ozone-depletion potential rating. XPS is extruded polystyrene foam board designed to create a single layer of thermal and moisture protection on a building’s walls, roof or floor, thereby greatly contributing to its overall energy efficiency. The insulation begins as solid granules of polystyrene resin, which are fed into an extruder where they are melted and mixed with additives to form a viscous fluid,” says Daneel.
A blowing agent is then injected into the viscous liquid to enable expansion. The mixture is forced through a die into a mould under carefully controlled heat and pressure conditions. After the board has hardened, it gets trimmed to various lengths and thicknesses to suit a wide gamut of commercial, agricultural and industrial thermal insulation applications.
“This continuous process results in a closed-cell structure, which imparts excellent long-term strength and durability to the XPS boards,” says Daneel.
Versatile, easy-to-install green insulation
Summit XPS Insulation Board comes standard with tongue-and-groove edging, which makes for exceptionally easy installation. It also provides a tight, energy-efficient seal, stopping air leaks and gaps, and preventing any hot or cold air from escaping.
It can also be used for a wide variety of applications, including as nail-up ceiling and insulation, also as ceiling insulation between trusses for an exposed truss look, over-rafter insulation, over-purlin insulation, cavity/perimeter wall insulation and under-floor (surface bed) insulation. Its closed-cell structure makes it strong, ensuring an exceptionally long lifespan when compared to some other materials.
