    We installed trickle vents from smartclimain the strawbale house. We are off-grid and didn’t want to have an air exchange system that depended on electricity to function. We are very pleased with the effect of the vents both in summer and winter. The house itself is very airtight and the vents allow air movement from outside to in and outside again without an appreciable impact on the temperature inside the house. Nor do we experience cold drafts in the vent areas or the “airpaths” throughout the house. We installed one vent low in the wall beside the woodstove and this provides ample air to maintain the fire without depleting interior oxygen levels. In essence it is like having several windows barely open throughout the house, but without the cold drafts….”
