DECKING For maximum protection, opt for an ‘above-the-joist’ system with poly or rubberized membranes that drape over the joists to ensure that the joists and beams of the substructure are shielded from moisture penetration. This type of system also helps to hold screws in place longer and acts as a shield between galvanized metal and timber. Furthermore, the membrane material (vs. metal, vinyl or PVC) accommodates a broader range of ceiling options for homeowners seeking a finished aesthetic. Systems that install below the joists leave timber and metal exposed to the elements and more susceptible to water damage and corrosion. This type of system can trap 68 www.landud.co.uk moisture in the core supports of the substructure. In warmer months, rising temperatures ‘cook’ the trapped, wet wood and accelerate rotting. Over time, this combination of moisture, heat and lack of ventilation can create a potentially dangerous formula for deterioration. Once protected, the dry space beneath a deck can be used for storage or as additional living space. Homeowners can add electricity, water and gas lines, as well as furniture, lighting, ceiling fans and entertainment components, depending on how they plan to use their new-found space. The possibilities are limitless, and the process is simple. Trex® RainEscape®, for instance, is a high quality, affordable, above-the-joist deck drainage system that can be installed using just a stapler, utility knife and caulk. Each trough is clearly labeled with staple markers to expedite the process, which takes no more than a few hours to complete. And, the system is backed by a 20-year warranty from the world’s #1 decking brand. Both of these upgrades add considerable function and value to a deck project without adding a lot of time or cost.
