No matter what time it is,even it’s hard time in the whole world, urban construction will not be stopped. Recently we received several questions,like “What to consider, when choosing an insulated panel for my project?” “Which parameters are important when choosing a sandwich panels?” Hereby Yumisteel team will make a systematic explanation for you.

☆ Definition of sandwich panel

Sandwich panels were result of thermal insulation and construction speed improvement in the construction industry. It’s made by two surface sheets and one layer of core material,we also called it as composited panels. The surface sheet of sandwich panels can be steel, aluminum, PVC, stainless steel, aluminum foils,etc. And core material can be polystyrene, rockwool, glass wool, Hollow glass magnesium, PUR, PIR,etc.

Sandwich panels are acting an important role in steel structure construction industry, because compared to single skin metal sheets,it’s more excellent performance on construction speed, soundproof and fireproof function,etc.

☆ Those factors we need to consider, when buying laminated panels

·Before purchasing:

What’s the purpose of the building?

For commercial use, we need to consider about esthetics of the building.

For industrial use, perhaps durable and long life service time will be best choice.

For resident use, there are various possible factors.

What’s circumstance that insulated panels will work for?

For example, near the sea, the local weather is extremely hot, or there is much precipitation.

What are the fire safety requirements of the building?

Any requirement for noise reduction?

Are there any requirements for indoor temperature?

Your budget for the project?

·During inquiry:

For the issues you consider before buying, you can explain the requirements of the insulation panel with the supplier. Then suppliers can offer technical data and professional suggestion for you.

Specifically speaking, they will offer you with the following information:

- U value or R value (thermal transmittance) as insulation properties of wall or roof,to verify if the panel thickness can meet up thermal insulated requirement;

- Verify supporting beams span,to make sure panel can bear the local wind,snow,rain load capacity;

- Offer related panel ribs type,or we say profiled on panel surface,and maybe make 3D drawings for your building,in order to show you how the appearance of the building will be;

- About colors, If you require indoor temperature to be lower,suppliers won’t advise you to use dark colors. Here we list one table for you to check about temperature difference on different colors:

- Explain to you each advantages of different kinds of laminated panels:

Polystyrene sandwich panels: Lightweight & Best price;

Rockwool sandwich panels: Best fireproof & soundproof;

PIR/PUR sandwich panels: Best thermal insulation material;

Glass wool sandwich panels: Fireproof

After discussion, you will find that you already have a concept of which sandwich panel is suitable for you, and make the right choice. According to your needs, Yumisteel team will offer you the correct panels, not expensive ones.
