5 Insulation Tips To Save Money & Energy


Installing energy-efficient insulation in your house is one of the quickest energy-payback projects you can perform, resulting in cheaper heating and cooling expenditures and better comfort.

Even if you live in an older house, you don’t have to suffer in the winter or bake in the summer. If your home lacks enough insulation, which was typical before 1980, when energy conservation became more popular, putting it up to current requirements will make it more pleasant all year. You’ll also save anywhere from 10% to 50% on your heating and cooling expenditures.

The amount of money you save by increasing your insulation depends on several factors, including where you live, your heating system, and how much insulation you install.

In the summer, sleeping without covers is a good idea, while doubling up on blankets is a good idea in the winter. A better solution would be to insulate your home correctly.

Recognize The Significance of Insulation

Insulation is essential for limiting heat flow, lowering utility bills, and keeping a pleasant temperature indoors, whether building a new house or remodeling an existing one. Home insulation drives hot air to excellent places to maintain a balanced temperature throughout the house by decreasing conductive heat movement or lowering heat uptake. You must consider the placement, material, and amount of insulation to ensure that it does its job effectively.

Insulate The Appropriate Places

You should insulate your home from the top down to the base for maximum efficiency. Fill up the spaces between the floor joists and rafters and the attic access door in the attic. The goal is to isolate the residential areas underneath the attic. All external walls, including those that separate living rooms, garage and foundation walls, and storage facilities, should be insulated. Cover the flooring as well, particularly those that are over crawl spaces and unheated garages—seal windows, doors, vents, and ducting using caulk or weather stripping and adding insulation.

Use The Appropriate Insulation Materials

Insulation may be created from various materials appropriate for multiple regions of the home. Rolls and bats are made of mineral fibers like fiberglass and rock wool and come in conventional sizes that fit attic walls and floor joists. Loose-fill insulation is blown into cavities, allowing it to fit into any size cavity. It also makes insulating hard-to-reach areas like attics with many cables, ducts, and pipes easier.

Exterior and foundation walls benefit from rigid foam or fiberglass insulation, whereas walls, attics, and floors benefit from foam-in-place insulation. You may also purchase tiny cans of foam-in-place insulation and apply it to window and door frames to avoid air leaks. Quality matters more; therefore, you can shop for insulation materials on Croylek if you want quality insulation materials.

Determine The Appropriate Level of Insulation

To discover how much insulation your home needs, consult your local building codes. Insulation is required on most unfinished attic floors, outside walls, and between the garage and living quarters. However, homeowners must also insulate the foundation walls and slabs in certain places. For a comprehensive understanding of the eligibility criteria for grants for loft insulation under the ECO scheme, refer to Warma UK’s detailed guide.

The R-value, which describes the resistance to heat flow, is proportional to the quantity of insulation. The more efficient the insulation, the higher the R-value, although the perfect number depends on the environment and the heating and cooling system type. For example, cold weather areas require more insulation and have a higher R-valve, while moderately warm areas require less insulation and have lower R-values. A local insulation contractor can assist you in determining the best R-value for your home.

Consider The Entire Season

Insulation keeps the chilly, drafty winter air out of your home during the cooler months, but it’s also responsible for maintaining the internal temperature acceptable throughout the summer. You may prepare your home’s HVAC or boiler systems to work efficiently all year long by installing the correct type and amount of insulation. Furthermore, proper insulation is crucial for seasonal boiler and HVAC maintenance. Increase the effectiveness of your efforts by insulating your home against drafts.

Insulation helps keep your home’s heating and cooling systems from working harder than they need, thus saving you money on your utility costs.

What Changes Should You Make To Enhance Insulation and Help Save on Energy Bills?

A few simple alterations and upgrades may transform your home and improve its energy efficiency. These include;

The Windows

You may adore your home’s windows, but you may dislike them, even more, when you learn that they increase your heating and cooling bills by 10% to 25% every summer and winter.

If your windows are made of wood, inspect them for deterioration and, if necessary, fill in any gaps using wood filler or caulking.

If you have aluminum windows, you may use draught excluders to improve your home’s insulation.

Window film can also be used on the inside of your windows. The quantity of light and heat that enters the house through the windows is reduced by window film.

Low-emission window film reduces the amount of heat that enters a home by 75%.

Increase the insulation of your windows with white blinds, curtains, or weather stripping, which may be personalized to match most house décors.

If you don’t plan on insulating all of your windows, concentrate on those facing south.

The Gaps in Doors

Heat can also escape via holes indoors, particularly towards the bottom.

Brush draught excluders for bottom doors are easy to operate, inconspicuous, and effective at minimizing heat loss.

Material draught stoppers are more appealing to the eye, but they might get in the way.

The Attic

One of the key “hotspots” for heat to escape as it rises is via your roof. Loose-fill and batt insulation are the two most common types of attic insulation.

The attic must first be air sealed before adopting one of these forms of house insulation. This entails covering fan housings on the duct’s attic side with a securely built enclosure.

It also entails using plywood to cover and seal holes such as dropped ceilings, soffits, and bulkheads on the attic side of the ceiling.

Loose-fill insulation is less expensive than the batt, and it can give better coverage if installed properly.

There’s a chance that the vermiculite insulation in your attic contains asbestos. Instead of disturbing it, engage an insulation professional to take care of it.

A professional would usually blast loose fill into the attic above the ceiling joists, but you may install batts, which are mineral wool fiber sheets, in a criss-cross pattern between the joists if you’re up to it.

The Walls

The insulation of wood frames and solid brick frame walls vary.

Loose-fill or sprayed foam insulation is blasted into a wood frame wall cavity through holes drilled into the drywall or siding.

A specialist must build a hollow since the cavity of a solid brick wall is generally 25 mm and, therefore, too little a fill to get any insulating advantages.

A new cavity wall is erected on the inside side of the wall, and new board stock and siding are put to the outside.

The Basements

Basement insulation is beneficial, but it is also debatable due to the numerous elements that impact it. The amount of energy and money saved is determined by the climate in your area and the sort of heating system you have.

You may choose between wall and ceiling insulation after determining whether insulating your basement is good for you and your property.

Wall insulation is simpler and more widespread, and it comprises rigid insulation laid on the outside of the walls, such as extruded polystyrene or hard fiberglass.

Interior insulation is ceiling insulation. Depending on the material you use, it might be pricey.


One of the most effective methods to enhance your home’s energy efficiency and minimize your heating and cooling bills is to upgrade your insulation.

You can’t just dump a few fiberglass batts into your attic and call it a day if you want your new insulation to produce optimum savings; you need a strategy. Following the above tips will help you get the most out of your insulation approach and save money on your energy costs.
