Interior storm windows have very little impact on the appearance of the window, although the window frame may appear slightly wider
Image
Interior window attachments such as these light-filtering roller shades can reduce heat gains while providing pleasant, diffuse natural light.
Image
Image
Jalousie windows use shutters rather than glass over the window openings to allow for maximum ventilation. Screens may be installed to keep out insects.
Image
Joist straps or hangers and metal connector plates can reinforce a post-and-pier foundation against seismic movement

Key connection points for a continuous load path for earthquake and high wind disaster resistance
Image
Kickout diverter flashing keeps bulk water from the roof from overflowing the gutter and continuously wetting the siding material.
Image
Knee braces do not stiffen a pile foundation as much as diagonal bracing, but they present less obstruction to waves and debris, are less prone to compression buckling, and may be designed for both tension and compression loads.
Image
Lack of insulation over the top plate can lead to ice dam formation on a low sloped roof.
Image
Image
Landscape trees and shrubs to funnel cooling breeze towards a home in hot climate zones.
Image
Landscaping and Bahama shutters can provide important shade for a designated cool room
Image
Large deciduous trees provide heat-blocking shade to the walls and windows of this house.

Likely amount of time and radiant heat exposure at which different types of window glass would break at 30 feet from the edge of a wildfire.
Image
Image
Locating windows on adjacent and opposite sides of the house will allow cross ventilation regardless of wind direction

Image
Loss of the fascia cover in high winds exposes the vinyl soffit to entry by wind-driven rain.
Image
Image
Low perimeter to area (P/A) ratio home designs reduce heat transfer and perform better in hot climate zones than high P/A ratio homes.
Image
Low-slope roof assemblies constructed of two deck sheathing layers sandwiching rigid foam, and topped with mechanically fastened membrane
Image
Image
Lower-story wall anchorage to masonry (or concrete) base. Straps properly nailed at wall studs.
Image
Image
Many hardware stores sell appliance bracing kits to secure the water heater to wall framing with metal straps
Image
Image
Image
Image
Metal birdstop is installed at the eaves of a tile roof to keep out birds, bats, rodents, and flying insects
Image
Metal connectors help resist wind uplift at the wall to roof framing connection.
Image
Metal hat channel provides a drainage gap of 1 inch between fiber-cement siding and mineral wool continuous insulation.
Image
Image
Metal termite shields make it easier to see termite tunnels and may discourage termite access to wood framing
Image
Minimum horizontal clearance between trees and plants on various slopes for wildfire resistance
Image
Image
Modern interior storm windows include new technology and sleek design features that offer an easy-to-install, cost-effective method for upgrading the energy efficiency of existing windows
Image
Modern Low-E storm windows are typically kept up year-round but can be removed without damage to the existing window frame, an important consideration for historic preservation projects
Image
Modern low-E storm windows can significantly improve the energy performance of the home by reducing both air infiltration and thermal conductance through the window assemblies
Image
Moisture-resistant plastic and fiber cement exterior trim and cladding are indistinguishable from wood building elements.
Image
Multi-layer honeycomb cellular shades such as these can provide summertime energy savings by blocking and reflecting solar heat, as well as wintertime energy savings by providing added insulation.
