Room Additions in North Hills With Glass to the Yard
North Hills room additions with thermally broken aluminum door frames and coated glass for hard inland sun, drawn for LADBS plan check.
A plain aluminum door frame passes heat straight through to the room side, so for a North Hills garden room we specify frames with a thermal break. Under hard inland sun, the inner edge of such a frame stays close to room temperature because a strip of resin separates the outer metal from the inner metal. Paired with coated dual glazing, it lets most of the garden wall be glass without the room overheating.
What the break does in the frame
The break is a strip of polyamide or poured resin set between the two halves of each frame member. Heat reaching the outside metal has to cross that strip, so the handle stays comfortable and condensation on the inner edge becomes rare. Anodized or baked finishes hold their color under strong sun and resist chalking. Stainless rollers and sealed corners keep a large slider gliding, and weep slots in the sill track let rain drain out. Bronze, black and white finishes are all offered, matched to the trim already on the house so the new wall reads as part of it.
Glass, beam and the LADBS set
Large panes sit under a beam the engineer sizes from the width of the opening, with posts carried down to footings. Panes close to the floor are tempered. A low-E coating reflects heat back out while letting daylight through, and an overhang or patio cover shades the glass through the hardest hours of sun. Plans for a North Hills address go to LADBS, the City of Los Angeles building department, and the energy forms list every window by size and rating. The frame choice appears on that schedule, so the reviewer reads the same figures the supplier quotes.
Room Additions in North Hills: what people ask
Yes. A thermally broken slider or folding wall can fill most of the garden side, carried by an engineered beam, with tempered panes low down. The door layout is drawn before framing begins, so the rough opening matches the unit that gets ordered.
Building out puts the new glass at yard level and keeps the work simpler. Building up keeps the garden, though the roof has to come off and an engineer checks the foundation and walls first. Setbacks and how much yard you want to keep usually decide between them.
The tie-in is listed apart from the room itself: the joint between the two roofs, the opening cut in the existing wall and the floor matched across the threshold. Holding it apart lets you compare frame and glass choices without that connection blurring the figures.
