What Is a Conditioned Space?
A conditioned space is a closed space in a building where the thermal conditions are deliberately controlled using natural, electrical or mechanical means within specified limits.
Rooms that do not have a heating or cooling system, but rely on the natural or mechanical flow of heat from adjacent rooms to maintain thermal conditions within certain limits, are considered air-conditioned rooms. Examples include toilets in which the conditioned air is drawn in by means of exhaust fans to maintain thermal conditions and atria which are based on natural convection current to maintain thermal conditions.
Air-conditioned rooms can be further classified using the following definitions:
A closed room in a building that is intentionally cooled to maintain thermal conditions below maximum criteria.
A locked room in a building that is intentionally heated to maintain thermal conditions above the minimum criteria.
Insulating Your Home
Insulation protects your home against environmental influences by tempering indoor temperatures to ensure comfort while reducing energy costs. To ensure proper insulation, it is important to know where to install it.
A properly insulated building should be covered from the roof to the foundation, but we know that there are cases where this is almost impossible.
The type of insulation chosen depends on several factors, including where it is applied.
Insulating Walls for new Buildings and Existing ones
One of the best and fastest methods for insulation during remodelling is the use of blow insulation. The blown insulation ensures a perfect air seal when installing with the sealing package technology. It can be easily installed and reduces the preparation effort. If you are rebuilding and the wall recesses are open, check the two-part spray foam or wet cellulose insulation.
When building a new home, you can choose from many alternatives, including insulated building boards, insulated concrete forms, and insulated concrete blocks. All these materials are considered insulation materials because they are made to increase the R-value of the building.
When building a traditional house with a frame, you should consider using advanced wall frame techniques. These techniques improve the overall R wall by reducing thermal bridges and maximising the insulated wall surface.
Insulate the Attic
If you plan to insulate your attic, consider using loose fleece insulation. Loose insulation is cheaper than fleece insulation and offers better coverage with proper installation. Before sealing, make sure to seal all air leaks and make any necessary repairs. Don’t forget to insulate your knee walls. During conversion, make sure there is free space between the decks and make sure the new addition is raised above the floor beams to leave room for insulation.
Insulate Air Ducts
Ducts must be sealed and insulated to reduce energy loss. Always try to install ducts in air-conditioned rooms in arches that have adequate insulation. If you have a cathedral ceiling (two equal, sloping sides running parallel to the pitch of the roof where both sides slope and meet at a ridge running along the length of the room), you need to keep the space between the roof terraces and the ceiling to have room for insulation and ventilation.
Foil-coated fleece insulation is recommended for cathedral ceilings because it has the permeability required for use in ceilings without an attic. A ventilation flap should be installed between the insulation and the roof terrace to maintain the ventilation duct. The most suitable level of ceiling insulation is R-30 strips, which are as thick as R-25 strips, but fit into a 2×10 frame. If the specification is available, you can also add rigid foam insulation that increases R-values and eliminates thermal bridges. However, this type of insulation must be covered with fireproof material if used in a building. The R-value refers to the thermal resistance of various insulation materials. The higher the R-value of the material, the better it insulates against heat and cold. The R-value of the insulation depends on the type of material, its thickness and density.
Insulate the Foundation of the House
A well-insulated foundation minimises problems with infiltration by insects, moisture and radon. Insulation of the foundation can be treated as walls if you choose insulating concrete moulds and insulated concrete blocks. Typically, when building a new house, you can insulate the foundation before filling the room.
The type of insulation in the basement depends on whether the basement was previously insulated or not. In new buildings, insulation reduces thermal bridges, heat loss, moisture protection, and condensation problems associated with poorly insulated areas. If you want to install internal insulation, you can use almost any type of insulation and save money. Use building codes to find out what types of insulation are allowed on basement walls.
Internal insulation must be equipped with fireproof coatings and not protect against moisture. The following types of insulation can be used:
- Blanket insulation
- Insulation of concrete blocks (new building)
- Foam plate insulation
- Insulating concrete forms (new building)
- Loose insulation
- Spray foam insulation (a good choice for ready basements)
Sloped plates can be insulated by digging the perimeter and installing foam sheets. If the building is new, it may be easier to install the foam panel only outside the panel and base or under the panel. Internal insulation board foundations offer greater resistance to termites.
