A Lammin thermal exterior door is reliable, and it stays tidy and straight. The door is safe, and it keeps heat inside even under challenging weather conditions because a durable weather strip is fitted on both the door and the frame. This provides a genuine, double door sealing.
A Lammin exterior thermal door the is ideal for the exterior door of a residential building or a warm store. Our outward-opening thermal exterior doors meet the modern requirements of thermal efficiency, and the double thermal frame structure ensures that the door remains tight even after years of use. The outer frame is made knotless by jointing, and therefore the resin of the knots does not become visible.
The price of energy rises year after year, and the importance of thermal efficiency in new building and renovation is growing constantly. For this reason, the thermal door is today a sensible choice for the exterior door of every home.
Our thermal doors are custom-made. The doors have effective polystyrene insulation and durable double sealing preventing air leakage. The triple glazing of the door ensures that heat will not escape through the window opening either.
Lammin thermal exterior door thickness is 70mm, and the door framework is made of laminated pine. The thermal exterior door is also available as a double door. An option that is more solid than the ordinary thermal exterior door is the Lammin Plus door with 90mm thickness and with thermal efficiency that is even higher than that of an ordinary thermal door.
