Instead of warm air entering your home rising to the top and escaping to a cooler environment the outdoor heat goes out of its way to enter your cool air conditioned house.
Roof insulation summer.
But insulation is also there to keep you comfortable in summer.
Cut each sheet to the desired size using a utility knife then fasten it in place using staples or adhesive.
The airflow from the soffits to the ridge vent keeps the roof cool and prevents ice dams and the material will block that flow.
It helps keep your home warm in the winter and cool in the summer.
In the warm months heat is constantly seeking cooler places drawn to your comfortably air conditioned home.
When it s hot outside the stack effect operates in reverse.
A fantastic but a premium solution for external insulation and mitigating the effects of heat in the summer could be the wood fibre insulation.
Insulation in a home works almost like a thermos.
Avoids nails or screws which could penetrate the metal roof and cause leaks.
Meanwhile in the winter it helps slow heat loss from the interior spaces.
Quality attic insulation will help your hvac system run at its peak efficiency cutting the energy costs by as much as half in some homes.
Insulating in and around your roof attic space also prevents long term damage from moisture build up or ice damming which results from the warm air trying to escape through the apex of the roof but instead heating up the snow.
To understand how attic insulation helps keep your home cool in the summer months you first have to be aware of the ways a poorly insulated attic can make your house hot.
Roofing materials often absorb the sun especially metal sheeting or asphalt shingles.
This heat is then transferred through your wooden beams and into your attic.
It s a misnomer that insulation only helps during winter.
This hot air rises naturally as it gains temperature.
Insulating with spray foam insulation.
This can be installed with a basecoat and silicone top coat once fully finished provides a decrament layer against the heating effects of the sun in the summer months.
In hot summer months proper attic insulation will keep your cold air in and will keep warm air out.
For the same reason insulation shouldn t touch the roof s underside.
In the summer attic insulation helps reduce heat gain through the ceiling to living spaces below.
Additionally insulation serves as a way to enhance sound proofing on the uppermost envelop of your house.
Staple plastic or foam baffles to the roof sheathing near the eaves to keep the material away.
Use rigid foam insulation to cover wider spans of roof sheathing between joists.
Sure the fluffy pink or white foam material helps stop heat from escaping through the walls over the winter but it plays just as vital a role during summer.
