Tag Archives: insulate dog house

Insulating a dog house is about trapping the dog’s own body heat: line the walls and roof cavity with rigid foam board or foil faced bubble wrap, seal the gaps with expanding foam or silicone, then keep the door opening narrow and fit a flap or offset entry. Cedar shavings or straw insulate better than blankets, which absorb damp and freeze. Never seal a house completely, moisture and ammonia need a high vent to escape. A raised floor and a wind blocked position do as much as insulation alone. Our wooden houses accept lining without modification, free shipping with no minimum order.
