How To Install A Fixed Window

Installing Fixed Windows

Acquire how to frame, tape, and seal from this passive-solar builder.

Equally builders of passive-solar homes in a severe climate, we combine heavily insulated concrete and stud walls with fixed glass windows on the s side for straight gain.

Big areas of insulated glass tin be installed economically if the units are standard sizes and fixed directly to the edifice's framework. We employ tempered glass fabricated for patio doors; they are available at reasonable price and resist near whatever course of abuse. If a unit of measurement must be replaced, it can be done easily using this form of installation.

Frame the crude opening with a 1/2-in. gap at the top and sides to allow for expansion and framing irregularities. Cuprinol or copper naphthalate preservative on the interior trim will reduce the water damage from condensation,which is inevitable. A few coats of marine varnish volition extend the life of the wooden sill.

Butyl tape greatly simplifies glazing. We use Butyl 440 tape from Tremco; it is a uniform bead of butyl caulk with a paper backing that prevents it from sticking to itself. It is packaged in coils and can be purchased at many hardware or paint stores. Automobile drinking glass installers also use it. Leaving the protective paper layer on allows you to install the tape against the interior stops, bank check the window for fit, remove the paper and instantly secure the window. We identify neoprene setting blocks under the window as it is installed to absorb expansion and wrinkle of the glass and frame. The blocks are site cut to the thickness of the window unit from 1/4-in. thick neoprene and are normally 1-ane/four in. long—ordinarily ii per panel. So we use Tremco mono caulk to seal the base of the window. Compressible foam rope in. wide fills the spaces at the sides and height of the window and allows for expansion.

The aluminum drip cap at the superlative of the window overlaps the brickmold trim on both sides, minimizing exterior trim and further reducing weathering problems. Every bit before long as the dominicus comes out, whatever drift of snow or water ice at the bottom of the window slides off the aluminum flashing (preferably a dark color).
