What is a DIY insulation kit?

The DIY insulation kit is a comprehensive thermal management solution to control climate efficiently. Its core lies a sophisticated 3mm closed-cell polyethylene foam that is strategically sealed between layers of reflective foil. This advanced system creates an exceptional barrier preventing heat transfer through structural surfaces, including windows and doors.

The kit includes all necessary installation components. The precisely sized insulation sheets and mounting accessories eliminate the need for additional purchases.

This system excels at stabilizing indoor temperature fluctuations and lowers cooling and heating expenses throughout the year. The material can reflect 95-97% of radiant energy, therefore, it helps establish and maintain optimal indoor comfort in external weather conditions.

With its user-friendly design, the kit allows for straightforward installation without requiring professional assistance. It is an ideal solution for homeowners and RV enthusiasts looking to enhance their space's energy efficiency. The kit works for numerous applications and consistently performs across different installation scenarios.

How does the DIY insulation kit work?

The insulation system operates through a dual-action mechanism that innovatively maximizes thermal efficiency. The exterior reflective foil layers actively deflect incoming radiant heat during summer months, preventing unwanted heat gain. Simultaneously, during winter, they retain interior warmth.

The carefully engineered polyethylene foam core establishes a robust thermal break, dramatically reducing heat conduction between interior and exterior environments. This approach delivers superior temperature control throughout the year.

The highly reflective surface technology can repel up to 97% of solar radiation, substantially decrease the burden on air conditioning systems, and reduce energy consumption. During colder seasons, this advanced technology reflects internal heat back into your living space to keep the warmth inside and improve overall comfort without consuming much energy.

The specialized closed-cell structure of the foam provides an additional barrier against heat transfer to enhance the system's insulation capabilities. This multi-layered approach ensures consistent performance across varying weather conditions.

Great if installed properly

This really helps keep my van cool when it’s 103 outside. Of course I have air conditioner running but I didn’t have to fight the heat in the back seat.

Good heat reflector

My house gets direct sunlight in the afternoon. I use it to partially cover the windows to reflect the heat. It’s been effective to reduce air conditioning.

Keeps out unwanted elements

Purchased to cover an opening in the wall and keep out foul smells and reduce humidity. It works great.

included stickers do not work + update

I ordered too short, so it didn't end up covering the entire window. I didn't want to mess it up around my portable ac unit exhaust, but it does block light and immediately I can notice it's a touch cooler in my living room. the adhesive stickers do not stay though, and it's in danger of falling until I can get more velcro strips. Debating if I want to buy another sheet or try to return this for a different oneUpdate: the seller reached out to offer me a refund without needing to return the item. Adding another star for their quick customer service. I'll still need heavier velcro, but I'll order another sheet to cover the rest of my window
