Finding gaps above a window air conditioner ( be frustrating, as it allows air to escape or enter, affecting the efficiency of your HVAC system. While sealing the sides with plexiglass is one option, it may not be perfect and can reduce efficiency. This article explores alternative methods to effectively cover the space above a window AC unit. We provide solutions such as attaching weather-stripping, using insulated side panels, rope caulk with acrylic glass, securing with foam insulation and plywood, and using spray foam sealant. Additionally, we discuss the importance of proper insulation and offer tips for camouflaging your window AC unit.
Covering The Gaps Above Your AC Unit
If you encounter gaps above your AC unit that cannot be easily mounted, there are several workarounds available. Here are effective methods to cover the spaces:
- Clean the window surface where the weatherstripping will be attached.
- Measure the gaps and cut adhesive foam weatherstripping to fit.
- Peel the protective paper and position the weatherstripping against the bottom sash of the window to create an airtight seal.
Get Insulated Side Panels
- Measure the gaps on both sides of the AC unit.
- Purchase accurately measured insulated side panels.
- Cut the panels according to the measurements and seal them with caulk or weatherstripping.
- Allow the caulk to dry before turning on the AC.
Use Rope Caulk
- Measure the gaps or estimate their size for spaces narrower than 1/8-inch.
- Tear off a piece of rope caulk that can fit into the space.
- Press the caulk into the gaps, ensuring they are filled.
- Wipe off any excess caulk before operating the AC.
Secure With Foam Insulation And Plywood
- Measure the gaps above or beside your AC unit.
- Mark the plywood according to the measurements.
- Cut the plywood using a circular saw.
- Use spray foam to seal the plywood through the gaps.
- Allow the foam to dry and trim off any excess.
Use Spray Foam Sealant
- Protect the surrounding area where you don’t want the foam to stray.
- Follow safety precautions and spray the sealant along the edges.
- Let it cure and add more layers for larger gaps.
- Trim off the excess foam with an insulation knife.
Camouflaging Your Window AC Unit
After properly sealing and insulating the edges and gaps, you can make your window AC unit more visually appealing by using the following techniques:
Use A Folding Screen
- Place a folding screen in front of the AC unit to blend it with your space.
- Choose a design that matches your preferences.
Conceal Behind Curtains
- Install cafe curtains that can easily hide the AC unit when it’s not in use.
- Pull aside the curtains for proper airflow and natural light.
Decorate Plastic Section With Colorful Tape
- Cover the plastic sections of the AC unit with double-sided tape featuring interesting designs.
- This technique can transform your AC unit into a unique design piece.
Build a Cabinet Around the Window AC
- Create a cabinet that encloses the AC unit.
- Decorate the cabinet to match your room’s aesthetic.
- Ensure sufficient space for air circulation.
To enhance insulation and prevent air leakage, consider the following measures:
- Upgrade windows and doors to energy-efficient options.
- Install quadruple-glazed windows and low-emissivity glass.
- Insulate edges, sides, and sashes.
- Use air-tight insulation and sealers.
- Address draughts and ensure proper ventilation.
Ensuring Proper Fit
To avoid sealing issues and ensure effective insulation, it is important to select a window AC unit that matches your window opening. Take accurate measurements to prevent complications.
Covering every gap and ensuring proper insulation is crucial for maintaining a comfortable home and avoiding moisture-related problems. By implementing the suggested solutions, such as weatherstripping, insulated side panels, rope caulk, foam insulation, and spray foam sealant, you can effectively cover the space above your window AC unit. Additionally, considering camouflage techniques and upgrading insulation can further enhance the functionality and aesthetic appeal of your window AC unit.
