Does adding an extra layer of home window tint help?

I put a diy layer of window tint on my kitchen window which gets a direct hit all afternoon. 1 layer may (?) be helping a little bit, would putting another layer on - maybe on the outside - help a bit more?Does adding an extra layer of home window tint help?
in my bedroom the sun hits my windows all morning and the room get hott as hell in the summer.


what i did ?...i bought some white window film that people use in bathroom for privacy , still lets the light in but it reflects the sun


i did it on the upper halfs of the windows and it at least 10 degrees cooler in the room now.


But i think a better solution would be some awnings on the outsideDoes adding an extra layer of home window tint help?
If you have duo pane windows, be very careful!!! If the tint is too dark, it will cause the window to absorb too much heat and it can crack the glass. I would suggest a sun screen. That way you can remove the screen and replace it with the original one during the winter when you may want all the sunshine you can get. Good Luck!!
actually they sell this car tint that makes the window almost like amirror then add your dark tint
An awning would solve your problem better.
Help to what? Keep the heat out?





Yes.





But I would also suggest curtains.

How is the ozone layer broken down in the stratosphere?





10 points to someone who can give ma good answer that I can understand.How is the ozone layer broken down in the stratosphere?
The ozone layer is created when the solar winds collide with the earth's magnetic field. It is also called the Van Allan Belt. The atoms in the solar wind is all ionized because of the sun's heat. There are 2 parts . The beta particles that is attracted to the North pole and makes it negative. The other part is alfa particles and they are attracted to the south pole and makes it positive. . At the same time every year they form a particle gun that blows a hole in the ozone layer at the poles.Now back to the charges at the poles ,this voltage and current holds the O3 and stabilizes the ozone layer . There is a built in automatic repair system to repair the ozone layer.If the ozone layer gets thin it will let alfa particles to come through and bombard the Nitrogen which will trans mutate to oxygen which repairers the ozone layer.How is the ozone layer broken down in the stratosphere?
green house gases thin the ozone layer. this causes more of the sun to shine through which is y we have global warming

  • How to use a layer 3 switch and a firewall?

    I have a layer 3 Cisco switch. I've made 10 VLANs with different IP address range and I want each VLAN users to be controlled by a firewall when they want to communicate with users in other VLANs. But my Cisco switch layer 3 module simply routes all packets to their destinations because it recognizes them all as connected subnets.


    How can I prevent this? I want all packets have to go to firewall and then firewall decides if packet is permitted or denied accessing other VLAN.How to use a layer 3 switch and a firewall?
    If they are all in the same switch, this is nearly impossible unless it's a Catalyst 6500 with a firewall blade. But I'm betting you're dealing with a 3750 or something similar.





    You might be able to assign a next hop using policy based routing, but I've never tried this. Not sure if it would work or not. But that's the only way I can think of to get them through an external firewall.





    You could set up access lists and apply them to the individual VLAN interfaces on the switch. It isn't stateful, but it might get you where you need to go.How to use a layer 3 switch and a firewall?

    How do you handle flashing when putting on a second layer?

    I've put on roofs before, but I've never put on a second layer of shingles. Now that I am, what do I do about flashing? Do I put on a second flashing layer? Do I replace the old flashing? Do I just leave the flashing as it is?





    Any help greatly appreciated!How do you handle flashing when putting on a second layer?
    To the best of my knowledge you just lay the new shingles on and go for it. If the flashing is Steel you would need to put on another flashing over the old and shingle as usual.

    What is a good layer for inbetween gravel and sand for a fish tank?

    What is a good divder for gravel and sand so they dont mix for a salt water fish tank?


    Ive heard of a gravel mesh where can i find them? or what would make a good gravel mesh?What is a good layer for inbetween gravel and sand for a fish tank?
    Why are you mixing gravel and sand? Dolomite /crushed coral or sand, you really don't need both unless you are going for a specific look. You can buy nylon netting (in various colors from Walmart or fabric store. They do sell the clear at pet stores or you can use a divider designed for the separaton of gravel colors at a good/larger LFS.
