Why Is My House So Hot?
Large windows and glass doors allow natural light into your home, but they also let in significant solar heat.
Standard glass offers little protection against the sun's infrared energy, causing rooms to overheat, glare to increase and air conditioning costs to rise.
Professional solar window film reduces heat, blocks up to 99% of harmful UV rays and improves comfort—all without replacing your existing windows.
How Solar Window Film Works
Solar window film is a multi-layer polyester film professionally applied to the inside of your existing glass. It works by reflecting and absorbing a significant portion of the sun's heat and harmful UV rays before they enter your property, while still allowing natural daylight through.
The result is a cooler, more comfortable interior with reduced glare, improved energy efficiency and enhanced protection for your furnishings.
How Much Cooler Can Your Home Be?
Professional solar window film can reject up to 79% of the sun's heat, block up to 99% of harmful UV rays, and reduce glare by up to 87%, depending on the glass type and film selected.
On a typical summer day in Spain, when the outside temperature is 35°C, a south-facing room with large untreated windows can easily reach 40–45°C in direct sunlight. Professionally installed solar window film can reduce solar heat gain by up to 79%, often lowering room temperatures by 8–12°C, creating a noticeably cooler and more comfortable living environment while reducing the need for air conditioning.
While every property is different, many homeowners notice a significant reduction in indoor temperatures, making sun-exposed rooms far more comfortable and reducing the need for constant air conditioning during Spain's hottest months.
Solar Film vs Blinds
Blinds reduce light only after the sun's heat has already passed through the glass, allowing much of that heat to become trapped inside your home.
Professional solar window film works directly on the glass, rejecting up to 79% of solar heat, blocking 99% of UV rays and reducing glare while preserving your natural light and outside views—making it a far more effective solution for Spain's climate.
Conservatory Heat Solutions
Conservatories are often the hottest rooms in a home because their large glass surfaces absorb and trap solar heat throughout the day.
Professional solar window film can reject up to 79% of solar heat, block 99% of harmful UV rays and reduce glare, transforming an overheated conservatory into a cooler, more comfortable space you can enjoy all year round.
Air Conditioning Cost Savings
