“As a mason, I already have some understanding of why a house like this is going to benefit the homeowners as far as the insulation, the efficiency, and the comfort – it’s going to be quiet, warm when you need it to be warm, cool when you need it to be cool – and I know that as the word gets out, people are going to come to the same conclusions on why this may be the best choice for them when it comes to building a home.”

To extend the use of an outdoor space and appeal to the desire to host family and friends, building an outdoor fireplace is an increasingly popular option.

These patio design elements are functional and attractive, giving any space a high-end look. With an outdoor wood-burning fireplace, homeowners can enjoy time on their patio late into the evenings or even deeper into the shoulder seasons. They make a great focal point for seating, add ambient light, and can even help keep bugs at bay.

The preparation of the base course is the most critical stage of building with the Comfort Block System.

Before beginning construction, all coursing requirements should be considered. Comfort Block units should be used as the base course blocks. When laying the first course, standard mortar may be used to overcome any excessive variation in foundation levels. This should be used between the foundation and the first course of Comfort Block units.

Block layers must ensure that the base course is level horizontally along the length and width of each block and that there are no steps between each block. Once the block layers have the base course leveled, the highly engineered blocks combined with good craftsmanship will ensure that the walls are plumb and maintain a consistently even height.

Before construction of the Comfort Block wall, ensure that all wall dimensions conform to the block dimensions to reduce gapping and cutting.

All steel reinforcement should be located according to engineering recommendations before the base course is constructed.
