Morgen Scaffolding keeps men efficient
Now you can continue masonry through freezing weather — at a reasonable cost! The answer is Morgen Tower Scaffolding with a winter enclosure accessory that lets you enclose only the work area and the fresh masonry. This simple plastic "greenhouse" elevates with the masons, laborers, materials and heaters as the wall is being built. The enclosure is assembled and covered at ground level, eliminating the dangers of handling heaters and drapes or panels on elevated scaffolding.
With the Morgen winter work enclosure and overhead protection accessory, you can schedule work right through the winter and offer steady employment to your men. At a price you can afford! Even in Canada masons are getting up to 50 weeks of work per year! In addition, Morgen Scaffolding gives you at least 20% more production from your masons and slashes the cost of scaffolding erection, moving and dismantling.
