In summer a similar concept applies.
Roof insulation to keep heat out.
I also prefer full width insulation baffles for the underside of the roof sheathing.
Ceiling insulation products and materials become the heat flow barrier between your roof tiles and ceiling boards.
If your home does get heated during the summer months look into adding more insulation in the attic or within the roof trusses.
By sealing off the eaves and encapsulating the attic roof deck this allows the hot air from outside of the home to stay outside and the air conditioning to work less by staying cool in the attic space.
It prevents heat from passing through.
Install insulation under the roofing material to reduce radiant heat gain.
Here s how it works.
The more insulation you have between the actual living area and the roof the better.
It s designed to reflect heat radiation but also comes combined with bulk insulation like glass wool or rock wool batts to create a composite type insulation which insulates against heat transfer through convection and conduction too.
Not sure sierraeast s recommendation would work if your roof is sagging due to inadequate support.
It will work as a barrier to keep the heat away from the home in the summer while keeping the warmth inside in the winter.
Roofs and ceilings work in conjunction when it comes to insulation.
Foil insulation is ideal for hot weather and is mostly used in roofs and walls.
Install insulation in the ceiling to reduce heat gain and loss.
Keeping you cooler in summer and warmer in winter throughout the year.
In winter your roof insulation blocks the cold air keeping your home warmer and giving your heater less work to do.
