The difference in the surface of aluminum foil is a result of the manufacturing process and has no bearing on heat retention or reflection.

Different pigment patterns provide camouflage throughout the seasons, and alter heat retention as temperatures change.

I have been known to remodel train stations on my lunch breaks, making them more efficient in the area of heat retention.

The frame should have thermal breaks built to help with energy conservation and heat retention.

This works on the same principle but has much poorer heat retention.

The cooked product has less shrinkage, moister taste and also better heat retention.

The attributes they were looking for were heat retention, crispiness and that it would survive the drive.

However, a significant disadvantage is the heat retention caused by heavier weight and darker colored fabrics.

The new surface is notably thinner, and therefore has lower heat retention.

The heat retention of the surface had also been a point of contention between players.
