Markic Development & Restoration Ltd.was formed in the spring of 2000 by John Markic, sole company owner. John has been involved in different aspects of construction for over 23 years. He is Carpenter by trade and has built over 70 homes in the lower mainland. John has a degree in Civil Engineering Technology and has taken the Building Envelope Course @ BCIT. He’s been involved in Building Envelope Restoration since 1997. He worked as a Carpenter for Perfect Waterproofing and Restoration and worked his way up to foreman, Site Superintendent, Project Coordinator to a proud business owner.
Markic Development & Restoration Ltd. is a young company trained and supervised by John Markic and thrives on new challenges. The company’s main focus is Service and Quality for their clients. MDR Ltd. has skilled workers and Sub-Trades whom have been with them for over 12 years and continues to train new man-power for future growth. MDR Ltd. has never needed to advertise their services, all their work generates from referrals and references through Consultants, Property Managers and most important, satisfied clients.
John Markic believes in being actively involved and supporting his local community. He is an active supporter of the local soccer club WVSC and coaches some of the teams.
Building Envelope Specialists
The building envelope (or building enclosure) is the physical separator between the interior and the exterior environments of a building. It serves as the outer shell to help maintain the indoor environment and facilitate its climate control.The control function is at the core of good performance, and in practice focuses, in order of importance, on rain control, air control, heat control, and vapour control. Control of rain is most fundamental, and there are numerous strategies to this end, namely, perfect barriers, drained screens, and mass / storage systems.
Control of air flow is important to ensure indoor air quality, control energy consumption, avoid condensation (and thus help ensure durability), and to provide comfort. Control of air movement includes flow through the enclosure (the assembly of materials that perform this function is termed the air barrier system) or through components of the building envelope (interstitial) itself, as well as into and out of the interior space, (which can affect building insulation performance greatly). Hence, air control includes the control of wind-washing and convective loops.
The physical components of the envelope include the foundation, roof, walls, doors and windows. The dimensions, performance and compatibility of materials, fabrication process and details, their connections and interactions are the main factors that determine the effectiveness and durability of the building enclosure system. Common measures of the effectiveness of a building envelope include physical protection from weather and climate (comfort), indoor air quality (hygiene and public health), durability and energy efficiency.
In order to achieve these objectives, all building enclosure systems must include a solid structure, a drainage plane, an air barrier, a thermal barrier, and may include a vapor barrier. Moisture control (e.g. damp proofing) is essential in all climates, but cold climates and hot-humid climates are especially demanding.
The thermal envelope (or heat flow control layer) is usually different than the building envelope. The difference can be illustrated by understanding that an insulated attic floor is the primary thermal control layer between the inside of the house and the exterior while the entire roof (from the surface of the shingles to the interior paint finish on the ceiling) comprises the building envelope. Building envelope thermography involves using an infrared camera to view temperature anomalies on the interior and exterior surfaces of the structure. Analysis of infrared images can be useful in identifying moisture issues from water intrusion, or internal condensation.
