![]() ![]() With the air infiltrating the attic and crawl space, the weather inside will never get cooler than the weather outside, despite the use of energy-consuming fans. The air coming in is humid and most-likely polluted. With these spaces vented, the weather inside can get up to 95 degrees in the summer. Also, the opened spaces causes air conditioned air to escape from the living area and insects and rodents to enter through the voids of the vents. However, ventilating these spaces allows air to bring in pollution, moisture, and other allergens into the home or building. Ventilating the attics and crawl spaces was the only way to deal with issues caused by heat transfer, air infiltration, and moisture brought on by condensation. ![]() The reason for these spaces needing ventilation is to address issues such as condensation, heat transfer, and the results of "stack-effect issues," which building design practices and standard materials were not capable of resolving. It is both customary and code-compliant in home and building design to ventilate crawl spaces and the attic. To extend the sustainable service life of commercial and residential buildings, new design practices and materials are continually being brought to the forefront. In order to achieve a more healthy, comfortable and stable indoor climate, the building's insulation, as well as the moisture and air barrier, need to work together. We provide warranty and maintenance packages with any building envelope upgrading.The temperature inside a building, the moisture coming into and out of the building, and the movement of air is all controlled by a system of design components and construction materials known as the building envelope. A quotation will then be drafted to outline any costs associated with the necessary work. Westerly can evaluate and report our findings regarding the condition of the exterior of your building and provide scope of work recommendations. New and improved air, vapour, or moisture barrier membranes (allow air out, no water in).Through wall flashings (breaks up wall and allows for ventilation every 10ft).Vertical / horizontal strapping (creates the air gap for ventilating walls).Think of rainscreen as an extra line of defense, prepared to shed any water ingress before it sees internal framing. These new systems allow your exterior walls to continuously ventilate behind the exterior cladding enabling walls to dry out faster, increasing air quality, reducing energy loss, and putting an end to rain penetration. If your building pre-dates the 1990s, chances are rainscreen systems were not implemented. Well thought out and installed detailingĪs technology advances new systems and materials are designed to increase building envelope performance.To ensure your building envelope system effectively meets these goals, your building envelope system must have: Energy efficiency and potential cost savings provided.Durability and longevity of the materials used.The quality of indoor air that it creates.The protection it provides from exterior weather.The effectiveness of a building's envelope is measured by several factors, all of which contribute to the comfort, health, and energy efficiency of a building. This barrier is crucial to the longevity of any building. While moisture control is critical in all climates, the wet environment found in Vancouver is especially taxing on a building's envelope.įailure to maintain or upgrade your building envelope could result in heat loss, air leakage and/ or penetration of rain ‐ which in turn causes poor indoor air quality, early deterioration of the structure and high energy costs due to energy inefficiency. This “skin” provides thermal and moisture protection creating a buffer between the building and outside elements. As licensed and experienced contractors, we are your building envelope restoration and repair experts in the lower mainland, and across BC.Ī “head-to-toe” building envelope consists of the roof, exterior walls, windows, doors, the foundation and everything in-between. Westerly Restoration specializes in small to medium sized building envelope projects. ![]()
