How a warm home that holds heat for generations is assembled from factory-made panels.
SIP is a “dry” construction technology: the house is assembled without liquid binding mixes, by mounting ready-made panels onto a structural frame of timber or light-gauge steel (LGS). Assembly works on any type of foundation and without heavy construction machinery.
A classic SIP is a monolithic three-layer structure. It is formed by firmly bonding energy-efficient insulation between two magnesite boards. Under powerful pressure in a hydraulic press these components fuse into a single whole: the ultra-strong Pirin Construct building panel.
At its core is Sorel cement: magnesium chloride and oxide that react to form an especially strong material with a cubic crystal lattice, far exceeding Portland cement in strength. The filler is expanded perlite and fine wood shavings; the reinforcement is basalt fibreglass mesh and a non-woven cotton layer.
A density of 0.88–1.07 g/cm³ guarantees solid walls and lets you hang heavy furniture without embedded mounts.
Combined with the insulation, the panel effectively muffles street noise, keeping the home quiet.
It withstands extreme temperature swings and more than 70 full freeze cycles without losing its properties.
The material is completely non-combustible, holds back open flame and gives off no acrid smoke.
Thanks to the elasticity of magnesium cement, the board bends but does not crack when the ground settles.
A clean, hypoallergenic material that contains no asbestos or formaldehyde and is completely unappealing to rodents, insects and fungus.
The inner layer comes from a leading German chemical group: the panel's key organ, responsible for life support and the climate inside the home.
Just as the heart pumps warmth around the body, our insulation keeps it inside the home. With a record-low thermal conductivity coefficient, it stays cool in summer and stores warmth in winter, cutting heating costs by up to 60%.
Unlike older materials, magnesite board has a natural self-regulating ability and works as a passive climate regulator (Moisture Buffering). It draws excess moisture from the room in damp weather and releases it back when the air is dry. This protects the inner layers from condensation, completely ruling out damp, mould or fungus. The home always keeps a healthy and clean microclimate.
The SIP building system is almost unlimited in use: its versatility allows complex, large-scale projects, buildings of unusual shape and unique design solutions. Light weight, easy assembly, a warm envelope and strong performance at an affordable price. The panels withstand moisture and temperature swings, are safe for health and take any finish, inside and out.
