SlateSpacer Makes Every Slate A Vent
SlateSpacer is a thin, concealed, stainless steel spacer that allows slates to be slightly separated, yet remain well supported, while preserving the water-shedding function of the roof. Slate roofs are inherently capable of breathing, but in practice, air movement is substantially constricted. Slate roofs are inherently capable of breathing, as they contain many tiny spaces, however, in practice the actual amount of air that can pass through them is very limited. Consequently, in temperate climates in particular, condensation can accumulate within the roof structure and damage slates, wooden supports (battens or closed decking) and other surfaces. As structures have become more air tight, and as interior water vapour levels have increased, the problem has grown. When slates of different thicknesses are placed next to each other, a small gap is created above the thinner slate that can allow air to pass (conventional overlaps are sufficient to prevent a weather-entry problem). But this...
