How do I waterproof my replacement windows? What is the cause of water leakage of replacement windows?

Replacement of windows how to do waterproofing? What is the cause of window leakage?

Households have windows, so that the home appears more transparent and bright, but the window leakage is the most likely thing to happen, and the window leakage occurs for more reasons, the window leakage if not repaired in a timely manner, the rain will corrode the window and the wall, so that the leakage of water is more and more serious.

Traditional window joints, generally with cement mortar to add full, although through the wind gently blowing sun later will easily produce small gaps, insulation properties are also relatively poor. Over time, it is inevitable that gaps occur, precipitation will of course seep in. Foam adhesive is now the latest type of home improvement materials, energy-saving and environmentally friendly, easy to use, easy to work. Because it is a flexible colloidal solution, it can be tightly bonded to the window seam without worrying about leaks and gaps, and has good thermal insulation properties.

What is styrofoam?

Foam adhesive is a kind of adhesive with foaming characteristics and bonding characteristics, it is mainly used in the door and window side seams, prefabricated components deformation joints and holes in the additive, sealing, bonding. With waterproof (anti-leakage), waterproof, sound insulation and noise reduction, flame retardant, heat insulation and heat preservation, heat insulation and heat preservation, sealing these roles, will be unfavorable conditions are blocked outside the adhesive.

What is a high-quality styrofoam adhesive?

1, look at the color: high-quality styrofoam hit out of the milky white (white that type). Color tone gray-black or especially yellow are not good (indicating the application of cost-effective and its quality of raw materials made of lesser to achieve the purpose of cost control);

2, look at the consistency: Styrofoam glue out of the foam, get out of the foam, can not be too thin and do not thicken, too thin foam will collapse, thickening of the foam will be dry and easy to collect;

3, look at the bubble holes: and so on after the drying of the styrofoam solid, cut open the foam, look at the bubble holes, the bubble holes are well proportioned and fine, the bubble holes are well proportioned and fine. Bubble holes, bubble holes are proportional and delicate for good foam, such as bubble holes are very large, indicating that the relative density is poor, it is not good (only after the density is high, styrofoam waterproofing, sound insulation and noise reduction, ductility strength and other properties are guaranteed);

4, look at the surface of the foam: a good foam surface is a gully shape; poor foam surface is flat, with wrinkles;

5, look at the size of the foaming: a good foam foam rounded and plump; poor foam foaming Full-bodied; poor foam foam small, and show collapse;

6, see the adhesion: good foam adhesion is good, poor bonding strength is not very good will lead to the project building body surface and aluminum alloy profiles or door frames bonding is not strong or even pull not tight.
