Insert Window Replacement vs Full Frame Window Installation
Insert windows are often called pocket windows because they slide into the existing frame of the old window. They are a fast and cost effective way to update windows.
· When the old frame is square, level and in good condition they are a great option.
· They are a great alternative for older home renovations with ornate and expensive trim work that must stay put.
· Cost of install and ease of install. Very little needs to be disrupted with an insert window
· Time: install per window is rather quick. Average install time is around a 45 minutes with removal of the old.
· Historic homes that must meet a period specific style, can update to a more energy efficient window without losing the character.
· New insulation cannot be added between the window frame and rough opening.
· Sill & water protection cannot be added.
· Essentially with an insert, a smaller window and frame is being installed in the existing opening. Light and glass is lost because of it.
· Even though the glass will be more energy efficient than your old glass, the frame will not be.
FULL FRAME WINDOWS OR NEW CONSTRUCTION
A new construction window is a completely new window, nothing existing is being reused. This window is the most efficient because it allows the entire opening to be updated to current building code. Insulated with foam, flashed properly, and caulked.
When is a new construction window required6+?
· The old window frame is deteriorated beyond repair
· A larger opening is required by fire egress code.
· An improvement in energy efficiency is desired by reducing air leakage.
· The existing window frame is not a candidate for insert window replacement.
· The maximum R and U values can be achieved when all areas, including the rough opening can be properly insulated.
· Allows code approved installation.
· The exterior window trim is minimized to provide the greatest glass area.
· Can accommodate any style window within that rough opening.
· They are used in all new home construction, they are the best in all cases when installed properly.
· Cost is the biggest issue for an existing home, however they can easily justify themselves for energy reasons, water & rot problems. Which are far more expensive in the long run.
· Many factors play a role in how easy or difficult the install will be. Type of siding, prep work with opening, type of interior, height of install, and those are just a few.
