Thermal Insulation Screen for West-Facing & South-Facing Windows
If your west-facing room turns into an oven every afternoon, the problem is solar heat gain through the glass. Interior blinds only trap that heat once it is already inside. The MBORMC H05 thermal insulation screen stops it on the outside — the solar-reflective mesh blocks up to 90% of UV rays and a significant portion of solar heat before it reaches your window.
Designed for American west-facing and south-facing windows, the H05 is custom-cut to your exact frame. It keeps rooms cooler in summer, protects hardwood floors and furniture from UV fading, and maintains daytime privacy — without darkening the room like a blackout shade.
Why Solar Screens Beat Interior Blinds for Heat Rejection
Once sunlight passes through your window glass, the heat is already inside your home. Interior blinds and curtains can only trap that heat against the glass — which is why a west-facing room with closed blinds still feels hot in the afternoon.
An exterior solar screen works differently. The mesh sits outside the glass and reflects a large share of the sun's energy back out before it can warm the window. US solar screen installers consistently recommend 90% density mesh for west-facing windows that take the brunt of the afternoon sun[citation:5][citation:8]. The H05 is built for exactly that use case.
Technical Specifications
Engineered for American sun exposure and window types.
Where the H05 Works
Designed for the rooms American homeowners struggle to keep cool.
West-Facing Windows
The most punishing sun exposure in US homes. The H05 reflects the late-afternoon heat that turns living rooms and bedrooms into ovens.
South-Facing Windows
All-day sun exposure. The H05 blocks UV year-round, protecting hardwood floors, rugs, and furniture from fading.
Sunrooms & Bonus Rooms
Large glass areas that overheat quickly. Solar screens cut the heat gain without making the room feel dark or enclosed.
Rooms with Glare
Reduce blinding afternoon glare on TVs and computer screens while keeping natural light and the view.
